Introduction to JUnit Jenkins

Jenkins means JUnit test XML report format. We can use this format in the TestNg tool when we require additional information about the test case. But before that, we need to configure Jenkins. In other words, we can say that it provides some different types of functionality for JUnit and the plugins for the other technology. Normally Jenkins is an open-source automation server that provides a different kind of functionality to the developer to build the test case, deploy their software, pipeline, etc.

What is JUnit Jenkins?

Jenkins comprehends the JUnit test report XML design (which is additionally utilized by TestNG). Therefore, when this choice is arranged, Jenkins can give valuable data about test results, for example, chronicled test result drifts, a web UI for reviewing test reports, following disappointments, etc.

To utilize this element, first set up your work to run tests, then, at that point, indicate the way to JUnit XML records in the Ant glob grammar, for example, **/construct/test-reports/*.xml. Be certain not to incorporate any non-report records into this example. You can determine different examples of records isolated by commas.

Do you also feel functional tests are one of the main elements for conveying top-notch programming? You share my viewpoint that we should help the designer robotize this errand to obtain practically identical outcomes and get meaningful pattern reports.

How to Use Plugins JUnit Jenkins?

Now let’s see how we can use JUnit Plugins as follows:

The JUnit module gives a distributor that consumes XML test reports produced during the forms and provides some graphical representation of the verifiable experimental outcomes (see JUnit chart for an example) as well as a web UI for survey test reports, following disappointments, etc. Jenkins comprehends the JUnit test report XML design (likewise utilized by TestNG). Jenkins can give valuable data about test results, like patterns, whenever this choice is designed.

Likewise, the module gives a conventional API to other unit-test distributor modules in Jenkins. This usefulness was important for the Jenkins Core until it was parted out to this module in the form of 1.577.

JUnit Jenkins Configuration

Now let’s see the configuration of Jenkins in JUnit as follows:

Test report XMLs: Specify the way to JUnit XML documents in the Ant glob language structure, for example, **/fabricate/test-reports/*.xml. Be certain not to incorporate any non-report records into this example. You can indicate numerous examples of records isolated by commas. The base registry of the fileset is the work area root.

Hold long standard result/blunder: If checked, any expected result or mistake from a test suite will be held in the test results after the form finishes. (This alludes to different messages printed for comfort, not to a disappointment stack follow). Such a result is constantly assuming the test fizzled, yet as a matter of course, extensive result from breezing through assessments is shortened to save space. Take a look at this choice, assuming you want to see each log message from breezing through assessments, yet be careful that Jenkins’ memory utilization can considerably increment accordingly, regardless of whether you never check out the experimental outcomes!

Wellbeing report enhancement factor: The intensification element to apply to test disappointments while processing the experimental outcome commitment to the form wellbeing score. The default factor is 1.0. A component of 0.0 will impair the experimental outcome commitment to fabricating wellbeing score, and, for instance, an element of 0.5 implies that 10% of tests bombing will score 95% wellbeing. The component perseveres with the form results to reflect changes in new forms.

Permit void outcomes: If checked, the default conduct of bombing and expanding on missing experimental outcome records or void experimental outcomes are changed not to influence the situation with the form. If it’s not too much trouble, note that this setting makes it harder to detect misconfigured occupations or assemble disappointments where the test instrument doesn’t exist with a mistake code while not delivering test report records.

Skip distributing checks: If this choice is uncontrolled, then, at that point, the module consequently distributes the test results to compare SCM facilitating stages. For instance, if you involve this element in a GitHub association project, the warnings will be distributed to GitHub through the Checks API. If this activity dials back your assembly, or you would rather not distribute the alerts to SCM stages, you can use this choice to deactivate this component.

Look at the name: If given and distributing checks empowered, the module will utilize this name while distributing results to compare SCM facilitating stages. On the off chance that not, a default of “Test” will be utilized.

How To Choose WordPress Plugins

WordPress plugins are helpful. But they can also slow a site down, invite hackers and even cause a Google penalty.

These are my top five considerations when choosing a WordPress plugin.

5 WordPress Plugin Considerations

The plugin is vetted by WordPress.

It is popular.

Changelog indicates plugin is not abandoned.

Support participation and feedback indicate a healthy plugin.

It doesn’t overlap with a currently installed plugin.

1. The Plugin Is Vetted by WordPress

Some paid plugins don’t have a free version. But many of the most respected plugins have a paid premium version and a free version that is vetted and included in the official WordPress plugin repository.

The fact that a free version has been vetted by WordPress provides assurance (to me) that there is some kind of quality control.

If a serious issue is discovered with a free plugin, WordPress will remove the download from its repository.

Coding that results in a vulnerability or a state of abandonment is one potential issue. There are many other reasons why a plugin may be removed, as outlined in the WordPress Plugin Guidelines.

It’s not a perfect system and doesn’t 100% ensure that the plugin is safe to install. But it’s generally safer than downloading a plugin that is not available through the official WordPress repository.

Premium plugins may undergo their own private testing. They are generally safe to purchase and download. However, it may be useful to research the testing and vetting practices before purchasing.

2. The Plugin Is Popular

I’m not totally convinced of the wisdom of crowds. However, I do feel a sense of safety in knowing that a WordPress plugin is popular and vouched for by many users.

Popularity by itself does not guarantee that a plugin is without issues. In fact, a few of the most popular plugins have been the sources of near-catastrophic issues or larding up web pages with needless code.

Nevertheless, popularity can (alongside other factors) contribute to an assurance that the plugin is likely safe and works reasonably well.

3. Changelog Indicates Regular Updates

Some plugins may be abandoned. Every plugin’s WordPress page notes when the plugin was last updated.

A plugin might not be updated because the function it performs is relatively simple. But in general, this is a sign that a plugin has been abandoned.

Abandoned plugins should in most cases be avoided.

WordPress is constantly evolving. Installing a plugin that hasn’t been updated could cause conflicts with the current version of WordPress or the version of PHP that your website runs in.

4. Support Feedback Indicates a Healthy Plugin

Every plugin page in the WordPress Plugin Repository has a support page. The support page may provide evidence of a plugin that has ongoing issues.

Typical issues might be that the code conflicts with other plugins. Sometimes the WordPress template may need changes in order for the plugin to function.

The support page will reveal any potential issues you may face before discovering them the hard way.

Plugin Doesn’t Overlap With an Installed Plugin

A common issue I see is when two or more plugins designed to do similar things overlap. This generally happens with structured data and speed optimization plugins.

The usual result is that you have more plugins than you need.

It’s important to use as few plugins as necessary. Overloading your site with plugins can slow down the server.

Even a plugin designed to speed up your site may slow down your site if you are using too many of them at the same time.

Before you install a plugin, think hard about how this plugin will solve your problems. If it doesn’t solve all of them, will installing a second or third plugin cause duplication in functions?

How to Choose a WordPress Plugin

These five considerations are not a complete list. You may want to take other factors including user reviews, the reputation of the company behind the plugin, whether the plugin is over-engineered and slows down the site, and so on into consideration.

Downloading plugins can seem like a shell game, where a pea is placed under a cup and then shuffled around.

Are you making an educated guess or just guessing?

I hope that what I consider important factors for judging if a WordPress plugin is trustworthy will help take some of the guesswork out of choosing a trustworthy WordPress plugin for your site.

Beginner’s Guide To Fluxbox Configuration

On any list of lightweight Linux window managers, you’ll find Fluxbox. Originally a fork of Blackbox, Flux is well known as a fast, light, highly configurable desktop. Unfortunately, Fluxbox’s emphasis on text files for nearly all configuration often acts as a roadblock for those first trying it out. There is a GUI which provides some of the basic config options, but the bulk of it (menus, colors, keybindings) is found in text files. In this article, we’ll go over most of Fluxbox’s config files and how to tweak them to your needs.

Since we’re focusing on configuration, the remainder of the article will assume you’ve already got Fluxbox installed. All examples and screenshots were done using Fluxbox 1.1.1 on Ubuntu 9.10.


Fluxconf is the basic configuration utility for Fluxbox. It doesn’t really have much beyond the most basic config options. It likely came with your Fluxbox package and so should already be installed, and can be launched with the command:

fluxconf Main Configuration

Much of the configuration you’re likely to want to do can be done in the file ~/.fluxbox/init file. Open it with the text editor of your choice, and you can set a wide variety of common options. Some of the more notable entries include:

session.menuFile: (location of the file containing the Fluxbox menu)

session.screen0.toolbar.widthPercent: (1 to 100, width of toolbar across screen))

session.screen0.toolbar.alpha: (0 to 255, transparency of toolbar. 255 is solid)

session.screen0.toolbar.autoHide: (true/false) (items to include in the toolbar, more detail in next section) (0 to 255, transparency of menu. 255 is solid)

session.screen0.workspaces: (number of workspaces or “virtual desktops”)


Setting a persistent wallpaper in Fluxbox can be surprisingly complex. There are various options to various programs that can all be used to set the wallpaper, either temporarily or permanently. For this reason, instead of going into all the complexities here, I’ll let the Fluxbox developers explain it in their own words.

Menu Editing

Fortunately, one of the more tedious aspects of configuration, menu editing, has a nice, functional GUI. The program fluxmenu, also bundled with your average Fluxbox package, does a good job of handling your menu needs.

If, for whatever reason, fluxmenu doesn’t do the job, you can edit the file ~/.fluxbox/menu by hand. Also, make sure you update the ~/fluxbox/init file to point to your custom menu file as described in the Main Configuration section of this guide.

Mouse and Keyboard Bindings

You’ll find keyboard and mouse config in the file ~/.fluxbox/keys. If, like me, you’re used to scrolling the mouse in the opposite direction to move between workspaces, you’ll find that under OnDesktop Mouse4 and OnDesktop Mouse5 near the top of the config file.

Fluxbox names some of the keys in a way that might not be obvious at first. If you find yourself confused by Mod1 and Mod4, here are the keys to which they map:

Mod1 = Alt

Mod4 = Windows (aka Super) key


You may have set some of the transparency options in the init file in a previous section. You may also have noticed that those transparencies may not have taken effect. Fluxbox, by default, does not have full compositing capabilities on its own, but you can get it through xcompmgr. They’ve created a guide located here with all the steps necessary to get xcompmgr and Fluxbox to play happily together. I’ve had mixed results getting this to work with various hardware and software combinations, so your mileage may vary.

How To Use Vlookup True With Examples

VLOOKUP with True

When we apply the Vlookup function, it is obvious that we always look for the exact match. When we get the #N/A, we also assume that the value we are looking for is unavailable in the lookup table. But we have yet to try using Vlookup with a TRUE value match. We can use two criteria in Vlookup functions, which are TRUE and FALSE. FALSE gives us the exact match, whereas TRUE gives us the approximate match for the value if not in the lookup range. Vlookup True is used when we don’t get an exact match, but with the help of TRUE, we can get an approximate match or near value to the value which we are looking for.

How to Use Vlookup True?

To understand the use of Vlookup True, first, we need to understand the syntax of Vlookup. Below we have the syntax of Vlookup;

Lookup_Value = Cell value whose value we need to find.

Table_Array = Range or table from where we need to find the value of lookup_value.

Col_Index_Num = sequence number of the column from which we want to get the value.

Range_Lookup = 0 (or FALSE) for the exact match and 1 (or TRUE) for the approximate match.

We will be seeing the use of TRUE and FALSE range_lookup value and will see how Vlookup True works in the below examples.

Examples of VLOOKUP True

Lets us discuss the examples of VLOOKUP names.

You can download this VLOOKUP True Excel Template here – VLOOKUP True Excel Template

Example #1

In this example, we will see the simple way to apply Vlookup True. For this, we have a list of alphabets, as shown below. As we can see, the alphabets are in proper sequence. And in separate cells, we will be looking up the values from the list and see the output.

In cell C2, we will put any of the alphabets we want to look up from Column A. Let’s consider it D.

In cell D2, insert the vlookup function and select the lookup value and range as needed.

To get the exact match, we can select FALSE range lookup or 0 for the exact match as shown below.

Once we enter, we can see that cell D2 will have the exact match value from the selected range.

Now, if we delete the Lookup Cell value D from the list available in column A, then Vlookup will not be able to look up anything and will return #N/A.

Once we exit the syntax, we will get the value nearer to the lookup cell value D in cell D2.

As we can see, the obtained value at cell D2 is C. This is because Vlookup TRUE gives the near about value if the exact match is unavailable. Here for the D, it returned the approximate match as C because C is the only near value before D.

Example #2

In this example, we will see how Vlookup True works with a larger data set. Below is a table where the names of the different persons, ages, and physique types are mentioned from Columns A to C. And there is another small table in column E: F where we will map the value from table 1.

As we can see, we have age and physique types for each person. Now, let’s find out the physique type of any age, say 26. Insert the vlookup at cell F2 as shown below.

Select the lookup cell E2 and the Lookup range from B2 to C8, as shown below.

Now, if we randomly change the age from 26 to 53 in cell E2 and again apply the lookup using TRUE range lookup criteria and see what we will get? As of now, when we change the cell E2 value from 26 to 53, we got #N/A, as there is no value in column C available for age 53.

Now we will apply the Vlookup function using TRUE.

Once we press enter or get exited from the Vlookup syntax, our physique type in cell F2 is GENERAL, as shown below.

The reason for getting General in cell F2 is the TRUE range lookup in vlookup syntax. As we did not have the age as 53, so Vlookup True returned us the value as General because, before 53, we got general physique in cell B4.

If we again change the value, let’s say 31. Then we will get a value closer to 31 per the table. Here we have 30 in cell B2.

Pros of VLOOKUP True

It helps us get the approximate match if we do not have the exact value for the lookup cell.

It is as simple as Vlookup False.

Using this function is far better than using different IF condition functions.

Things to Remember

It gives an approximate match.

We can also use 1 in place of TRUE in the VLOOKUP syntax.

For the numerical value, It looks up the value less than the value available in the lookup cell.

Vlookup False gives the exact match, and if the match value is not available, then we will be getting #N/A

#N/A means the lookup cell’s value is not found in the entire lookup range.

The lookup range could be a table or column, but the value we will get from the column only.

How To Use Scrapy Formrequest With Examples?

Introduction to Scrapy FormRequest

Web development, programming languages, Software testing & others

What is Scrapy FormRequest?

Traditional scraping techniques will get a long way, but we will run across the problem of Login pages sooner or later. We may wish to scrape data, but we won’t be able to do so unless we have an account logged in.

Scrapy, by default, visits the website while “not logged in.” Fortunately, Scrapy includes the FormRequest tool, which allows us to automate login into any website if we have the necessary information.

Each site has its own set of fields, which must be found by the login procedure and watching the data flow.

How to Use Scrapy FormRequest?

A successful login is very important to developing an automated login. We can implement automated login by using scrapy FormRequest.

Web scrapping is complicated, and there is no one-size-fits-all approach that will work on all websites. Each Spider must be customized to interact with a single website. However, as explained below, the general notion and concept usually remain the same. The below steps show how to log in with FormRequestare as follows.

Examine the site’s log-in page. Recreate the login process and list the “Form Data” fields and values. In particular, keep a look out for hidden fields.

Using our Spider, go to the site’s login page.

Create parsing functions and add the Scrapy FormRequest with the form data we collected before.

Make sure our key fields (for form data) correspond to the website’s key fields. After all, variation is to be expected.

Include a quick check to ensure that we have entered our credentials correctly. Look for differences between the “before login” and “after login” pages. This modification will make it easier to tell if we have logged in correctly.

After completing the preceding steps successfully, we can now include the parsing function for data we wish to scrape from the website. In addition, regular Scrapy techniques such as rules and so on are now available.

The below step shows how to use scrapy FormRequest as follows.

1. In this step, we install the scrapy using the pip command. In the below example, we have already installed a scrapy package in our system, so it will show that the requirement is already satisfied, then we do not need to do anything.

pip install scrapy

2. After installing the scrapy in this step, we log into the scrapy shell by using the scrapy shell command, or we can also write code into the visual studio.

scrapy shell

3. After logging into the python shell, duplicate the “Form Data” arguments. If one of the details changes, inspect the page for the changing feature in the source code and extract it into a variable. Then use return FormRequest to include the login information and the name of the callback function that will identify what we want to do scrape from the page we will be routed to after signing in.


def parse (self, response): py_tok = response.xpath ('//*[@name="py_token"]/@value').extract_first () return FormRequest.from_response (response, formdata = { 'py_token' = py_tok, 'password' = 'scrapy', 'username' = 'scrapy'}, Callback = self.scrape_pages)

Scrapy FormRequest is a dictionary that stores arbitrary request metadata. Its content will be submitted as keyword arguments to the Request callback. It’s empty for new Requests.

The dict is shallow copied and can also be accessed from the response in our spider. Cb_kwargs is a variable.

This dict can be seen in the request’s errback as a failure. chúng tôi kwargs in the event of a request failure.

Scrapy FormRequest Examples

Except for any members whose values have been changed by the keyword arguments. By default, shallow copies are made of the chúng tôi kwargs and chúng tôi attributes.

The HTTP method, URL, headers, cookies, and body are all filled up. This is because it precedes the values of the same arguments in the cURL command.

The below example shows that examples of scrapy formrequest are as follows. In the below example, we will be splitting the function into two parts. The first one, parse, is executed automatically on the start URL we defined. Make the start URL or request point to the site’s login page.

We obtain the value of the CSRF token in the parse function and feed it along with the login and password we used before into the FormRequest function.

Example #1

The below example shows a simple code of scrapy formrequest as follows.


class ScrapySpider (CrawlSpider): py_name = 'scrapy' def parse (self, response): py_token = response.xpath ('//*[@name="py_token"]/@value').extract_first() print (py_token) yield FormRequest.from_response(response, formdata={'py_token': py_token, 'username':'scrapy', 'password': 'scrapy'}, callback=self.parse_after_login) def parse_after_login (self, response): print (response.xpath('.//div[@class = "col-md-4"]/p/a/text()'))

It’s worth noting that the FormRequest is tied to a function called parse after login. After a successful login, this function is in charge of handling all subsequent activities.

In this new function, we’ve introduced a single line that checks whether or not the login was successful. According to our observations, the website says “login” in a certain part. However, it will also say “log out” if we are logged in.

Example #2


def parse (self, response): py_form = { } return [FormRequest(py_url = py_url, method = "POST", formdata = py_form, callback = self.parse_form)]

Example #3

In the below example, we are using formrequest with chúng tôi URL. In addition, we have used email ID and password to validate the request.


def start_requests (self): print 'scrapy login' py_headers = self.make_header (response), formdata = { "email": "[email protected]", "password": "scrapy", }, callback = self.parse_page )]


Each site has its own set of fields, which must be found by the login procedure and watching the data flow. Scrapy formrequest crawls online sites using Request and Response objects. Request objects are typically generated in the spiders and passed through the system until they reach the downloader.

How To Use A Bluetooth Keyboard With Ipad

Want to use an external Bluetooth keyboard with the iPad? You don’t have to use Apple’s official iPad keyboards, instead if you already own a Bluetooth keyboard the chances are good that it will be compatible with the iPad. If you’re looking to do a lot of typing on the iPad then it’s hard to beat a real external keyboard, as the touchscreen is generally just slower and less accurate for many iPad users. To get a Bluetooth keyboard connected to iPad, all you need to do is pair the device to the iPad and adjust a few iOS settings, we’ll walk through exactly how to do just that.

How to Set Up iPad with a Bluetooth Keyboard

This method will sync any Bluetooth keyboard with any iPad model, for use as an external keyboard.

Put the keyboard into pairing mode, on the Apple Wireless Keyboard this is done by holding down the Power button for a few seconds

The iPad will present a popup notification with a pairing code, type this into the keyboard to confirm syncing

Now you can use your Bluetooth keyboard with the iPad

Once the Bluetooth keyboard has been connected and paired with the iPad, you can use it as your primary text input device, anywhere that you would normally type on the iPad.

Launch any app where the virtual keyboard would normally appear and you can type with the external keyboard instead, and best of all, the virtual keyboard stays hidden when a wireless keyboard is connected, clearing up considerable screen real estate on the iPad screen.

Another great thing about this feature is that you can use almost any existing bluetooth keyboard with the iPad and you’ll be completely wireless. Plus you get the benefit of being able to rotate the iPad to either vertical or horizontal mode and still use an external keyboard, something you can’t do with some particular keyboard cases, the Smart Keyboard, Apple’s iPad keyboard dock, and some others. Additionally, using external keyboards with the iPad will introduce a variety of very helpful keyboard shortcuts for navigation that are not otherwise accessible on the software virtual keyboard of iOS.

Troubleshooting iPad Bluetooth Keyboard Issues

A few quick troubleshooting tips for getting a Bluetooth keyboard working with iPad:

Make sure that Bluetooth is enabled on the iPad (via Settings, or Control Center)

Toggle Bluetooth off and back on again can sometimes help to find a Bluetooth Device if it’s not immediately available

Make sure the Bluetooth keyboard has sufficient power, battery, or charge, if in doubt charge it or change the batteries first

Sometimes simply rebooting iPad, and then turning the Bluetooth keyboard off and back on again afterwards, can resolve difficulty finding the keyboard

If the keyboard is not listed in the iPad Settings Bluetooth section, check to be sure that the keyboards batteries are adequately charged and that it is in pairing mode, both of which may prevent the device from appearing in the Bluetooth menu on the iPad. Many Bluetooth issues are simply a matter of having either too low of battery power, or no battery charge at all. Changing and charging batteries is often a simple remedy.

Another possibility is that the Bluetooth keyboard is incompatible, though this is fairly rare and typically only applies to much older keyboards from the PC world. This can apply if the keyboard doesn’t fit the ‘Bluetooth Human Interface Device Profile’ that allows for compatibility with iOS, but most newer Bluetooth keyboards do so the chance of you running into one that doesn’t is relatively slim unless it’s a pretty old keyboard from the Windows world.

With all this in mind, it makes a lot of sense to get a nice Bluetooth keyboard that you enjoy using and that you like typing on. There are many options, but if you have several different Apple products you may like the Apple Wireless Keyboard since you’ll be able to use it not only on your iPad, iPad Pro, or iPad Mini, but also any other Mac, and even the iPod touch and iPhone. Yes, that’s right, you can turn the tiny little iPhone or iPod touch into the worlds smallest workstation by connecting an external wireless keyboard to either an iPhone or iPod device too. Also, if you have a newer Apple TV, you can even sync a bluetooth keyboard to that as well and use it as a way to control and search your media. This makes one of the Apple Wireless Keyboards an excellent purchase, since it will work flawlessly with quite literally just about any Apple product, whether it’s an iOS device, Apple TV, or Mac OS X based Mac you have in the house.
