Suggested April 2024 Database Testing Using Selenium: How To Connect?

Database Connection in Selenium

Selenium Webdriver is limited to Testing your applications using Browser. To use Selenium Webdriver for Database Verification you need to use the JDBC (“Java Database Connectivity”).

JDBC (Java Database Connectivity) is a SQL level API that allows you to execute SQL statements. It is responsible for the connectivity between the Java Programming language and a wide range of databases. The JDBC API provides the following classes and interfaces

Driver Manager

Driver

Connection

Statement

ResultSet

SQLException

How to Connect Database in Selenium

In order to test your Database using Selenium, you need to observe the following 3 steps

Step 1) Make a connection to the Database

In order to make a connection to the database the syntax is

DriverManager.getConnection(URL, "userid", "password" )

Here,

Userid is the username configured in the database

Password of the configured user

And the code to create connection looks like

Connection con = DriverManager.getConnection(dbUrl,username,password);

You also need to load the JDBC Driver using the code

Class.forName("com.mysql.jdbc.Driver"); Step 2) Send Queries to the Database

Once connection is made, you need to execute queries.

You can use the Statement Object to send queries.

Statement stmt = con.createStatement();

Once the statement object is created use the executeQuery method to execute the SQL queries

stmt.executeQuery(select * from employee;); Step 3) Process the results

Results from the executed query are stored in the ResultSet Object.

Example of Database Testing with Selenium

Step 1) Install MySQL Server and MySQL Workbench

Check out the complete guide to Mysql & Mysql Workbench here

While installing MySQL Server, please note the database

Username

Password

Port Number

It will be required in further steps.

Step 2) In MySQL WorkBench, connect to your MySQL Server

In the next screen,

Select Local Instance of MySQL

Enter Port Number

Enter Username

Enter Password

Step 3) To Create Database,

Enter Name of Schema/Database

Step 4) In the navigator menu,

Enter Table name as employee

Enter Fields as Name and Age

Step 5) We will create following data

Name Age

Top 25

Nick 36

Bill 47

To create data into the Table

In navigator, select the employee table

Enter Name and Age

Repeat the process until all data is created

Step 6) Download the MySQL JDBC connector here

Step 7) Add the downloaded Jar to your Project

Select the libraries

You can see MySQL connector java in your library

Step 8) Copy the following code into the editor

Package htmldriver; import java.sql.Connection; import java.sql.Statement; import java.sql.ResultSet; import java.sql.DriverManager; import java.sql.SQLException; public class SQLConnector { public static void main(String[] args) throws ClassNotFoundException, SQLException { String dbUrl = "jdbc:mysql://localhost:3036/emp"; String username = "root"; String password = "guru99"; String query = "select * from employee;"; Class.forName("com.mysql.jdbc.Driver"); Connection con = DriverManager.getConnection(dbUrl,username,password); Statement stmt = con.createStatement(); ResultSet rs= stmt.executeQuery(query); while (rs.next()){ String myName = rs.getString(1); String myAge = rs.getString(2); System. out.println(myName+" "+myAge); } con.close(); } }

Step 8) Execute the code, and check the output

Selenium Database Testing Summary

Step 1) Make a connection to the Database using method.

DriverManager.getConnection(URL, "userid", "password")

Step 2) Create Query to the Database using the Statement Object.

Statement stmt = con.createStatement();

Step 3) Send the query to database using execute query and store the results in the ResultSet object.

ResultSet rs = stmt.executeQuery(select * from employee;);

We will create following data

How To Download & Install Selenium Webdriver

Selenium WebDriver Installation

Selenium installation is a 3-step process:

Step 4: Configure Eclipse IDE with WebDriver

In this tutorial, we will learn how to install Selenium Webdriver. Below is the detailed process

NOTE: The versions of Java, Eclipse, Selenium will keep updating with time. But the installation steps will remain the same. Please select the latest version and continue the installation steps below-

Step 1 – Install Java Software Development Kit (JDK)

Download and install the Java Software Development Kit (JDK) here.

This JDK version comes bundled with Java Runtime Environment (JRE), so you do not need to download and install the JRE separately.

Once installation is complete, open command prompt and type “java”. If you see the following screen you are good to move to the next step.

Step 2 – Install Eclipse IDE

Download the latest version of “Eclipse IDE for Java Developers” here. Be sure to choose correctly between Windows 32 Bit and 64 Bit versions.

You should be able to download an exe file named “eclipse-inst-win64” for Setup.

This will start eclipse neon IDE for you.

Step 3 – Selenium WebDriver Installation

You can download Selenium Webdriver for Java Client Driver here. You will find client drivers for other languages there, but only choose the one for Java.

This download comes as a ZIP file named “selenium-3.14.0.zip”. For simplicity of Selenium installation on Windows 10, extract the contents of this ZIP file on your C drive so that you would have the directory “C:selenium-3.14.0”. This directory contains all the JAR files that we would later import on Eclipse for Selenium setup.

Step 4 – Configure Eclipse IDE with WebDriver

Launch the “eclipse.exe” file inside the “eclipse” folder that we extracted in step 2. If you followed step 2 correctly, the executable should be located on C:eclipseeclipse.exe.

When asked to select for a workspace, just accept the default location.

A new pop-up window will open. Enter details as follow

Project Name

Location to save a project

Select an execution JRE

Select the layout project option

4. In this step,

A pop-up window will open to name the package,

Enter the name of the package

Name of the class

This is how it looks like after creating class.

Now selenium WebDriver’s into Java Build Path

In this step,

Select all files inside the lib folder.

Select files outside lib folder

6. Add all the JAR files inside and outside the “libs” folder. Your Properties dialog should now look similar to the image below.

Different Drivers

HTMLUnit is the only browsers that WebDriver can directly automate – meaning that no other separate component is needed to install or run while the test is being executed. For other browsers, a separate program is needed. That program is called as the Driver Server.

A driver server is different for each browser. For example, Internet Explorer has its own driver server which you cannot use on other browsers. Below is the list of driver servers and the corresponding browsers that use them.

You can download these drivers here

Browser Name of Driver Server Remarks

HTMLUnit HtmlUnitDriver WebDriver can drive HTMLUnit using HtmlUnitDriver as driver server

Firefox Mozilla GeckoDriver WebDriver can drive Firefox without the need of a driver server Starting Firefox 45 & above one needs to use gecko driver created by Mozilla for automation

Internet Explorer Internet Explorer Driver Server Available in 32 and 64-bit versions. Use the version that corresponds to the architecture of your IE

Chrome ChromeDriver Though its name is just “ChromeDriver”, it is, in fact, a Driver Server, not just a driver. The current version can support versions higher than Chrome v.21

Opera OperaDriver Though its name is just “OperaDriver”, it is, in fact, a Driver Server, not just a driver.

PhantomJS GhostDriver PhantomJS is another headless browser, just like HTMLUnit.

Safari SafariDriver Though its name is just “SafariDriver”, it is, in fact, a Driver Server, not just a driver.

Summary

Aside from a browser, you will need the following to start using WebDriver

When starting a WebDriver project in Eclipse, do not forget to import the Java Client Driver files onto your project. These files will constitute your Selenium Library.

With a new version of Selenium, there is no browser that you can automate without the use of a Driver Server.

How To Insert A Record Into A Table In A Database Using Jdbc Api?

Syntax INSERT INTO TABLE_NAME (column1, column2, column3,...columnN) VALUES (value1, value2, value3,...valueN); Or, | Field   | Type          | Null | Key | Default | Extra | | ID      | int(11)       | NO   | PRI | NULL   | | | NAME    | varchar(20)   | NO   |     | NULL    | | | AGE     | int(11)       | NO   |     | NULL    | | | SALARY  | decimal(18,2) | YES  |     | NULL    | | | ADDRESS | char(25)      | YES  |     | NULL    | | import java.sql.DriverManager; import java.sql.SQLException; import java.sql.Statement; public class InsertRecordsExample {    public static void main(String args[]) throws SQLException {             DriverManager.registerDriver(new com.mysql.jdbc.Driver());             String mysqlUrl = "jdbc:mysql://localhost/mydatabase";       Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");       System.out.println("Connection established......");             Statement stmt = con.createStatement();             String query = "INSERT INTO CUSTOMERS(" + "ID, Name, AGE, SALARY, ADDRESS) VALUES "          + "(1, 'Amit', 25, 3000, 'Hyderabad'), "          + "(2, 'Kalyan', 27, 4000, 'Vishakhapatnam'), "          + "(3, 'Renuka', 30, 5000, 'Delhi'), "          + "(4, 'Archana', 24, 1500, 'Mumbai'),"          + "(5, 'Koushik', 30, 9000, 'Kota'),"          + "(6, 'Hardik', 45, 6400, 'Bhopal'),"          + "(7, 'Trupthi', 33, 4360, 'Ahmedabad'),"          + "(8, 'Mithili', 26, 4100, 'Vijayawada'),"          + "(9, 'Maneesh', 39, 4000, 'Hyderabad'),"          + "(10, 'Rajaneesh', 30, 6400, 'Delhi'),"          + "(11, 'Komal', 29, 8000, 'Ahmedabad'),"          + "(12, 'Manyata', 25, 5000, 'Vijayawada')";       int i = stmt.executeUpdate(query);     System.out.println("Rows inserted: "+i); } } Output Connection established...... | ID | NAME      | AGE  | SALARY | ADDRESS         | | 1  | Amit      | 25   | 3000.00 | Hyderabad      | | 2  | Kalyan    | 27   | 4000.00 | Vishakhapatnam | | 3  | Renuka    | 30   | 5000.00 | Delhi          | | 4  | Archana   | 24   | 1500.00 | Mumbai         | | 5  | Koushik   | 30   | 9000.00 | Kota           | | 6  | Hardik    | 45   | 6400.00 | Bhopal         | | 7  | Trupthi   | 33   | 4360.00 | Ahmedabad      | | 8  | Mithili   | 26   | 4100.00 | Vijayawada     | | 9  | Maneesh   | 39   | 4000.00 | Hyderabad     | | 10 | Rajaneesh | 30   | 6400.00 | Delhi | | 11 | Komal     | 29   | 8000.00 | Ahmedabad | | 12 | Manyata   | 25   | 5000.00 | Vijayawada | 12 rows in set (0.06 sec)

8 Picture Books About Using Technology To Connect With Others

These books with characters who use tech to communicate with those they can’t be with in person should engage early learners.

Many years ago, a resourceful kindergarten student in my class took a piece of scrap wood, cut out and glued square foam pieces onto the wood, and created a model of a personal cell phone. In the land of pretend, as well as in reality, there are always urgent phone calls, emails, and texts to respond to, and this child’s improvised ingenuity told me two things: Cell phones had high value in this child’s world, and he wanted a device so much that he was willing to devote time and resources to create one. 

The eight joyful picture books that follow celebrate technology as a set of tools and devices that allow characters to communicate with each other and within their world. This collection features characters who use simple technology for self-expression, communication, and relationship building; characters take and send photos, email, texts, and video chat. Reading these books in the classroom offers the opportunity to have foundational social and emotional learning and STEM discussions couched in a literacy setting.

Three titles in this picture book collection—Marisol McDonald and the Clash Bash, See You Someday Soon, and Tea With Grandpa—feature cell phones and computers as valuable tools for fostering intergenerational communication; in each of these titles, young children video-chat with a grandparent.

8 books with characters who use simple technology to communicate 

See You Someday Soon, by Pat Zietlow Miller, illustrated by Suzy Lee. A grandchild and grandmother are geographically apart but find ways to be together, including online and talking on the phone, until they can be reunited. (Preschool–grade 1)

One Blue Gnu, by Danna Smith, illustrated by Ana Zurita. When a box of cell phones falls off the back of a truck at the zoo, eager animals swarm to claim a cell phone for their very own. Gnu begins an unforeseen phone chain that cumulatively invites 54 animals to a pool party at his house (as well as an unexpected carnivorous guest). (Preschool–grade 2)

Tea With Grandpa, by Barney Saltzberg. Ebook. A grandfather and granddaughter meet for tea each day at 3:30 p.m. They share stories, sing songs, and have a wonderful time. The last page reveals that this daily event is carried out via a video call. (Preschool–grade 2)

Dot, by Randi Zuckerberg, illustrated by Joe Berger. At home, Dot swiftly and confidently navigates between her computer, her tablet, and her smartphone. Sometimes, however, too much technology puts her system on overload, so she goes outside to recharge by spending time with her friends. (Preschool–grade 3)

Goodnight Selfie, by Scott Menchin, illustrated by Pierre Collet-Derby. A young girl inherits her brother’s camera phone. She immediately spends the day taking numerous selfies and some “elsies” (photos with someone else). She ends the day with one final selfie: a “goodnight selfie.” (Preschool–grade 3)

I Wanna Go Home, by Karen Kaufman Orloff, illustrated by David Catrow. When their parents go to Bora Bora, Alex and his brother and sister visit their grandparents at Happy Hills Retirement Community for two weeks. In this story, told in a series of emails, Alex sends his parents daily grievances, but very soon he has delightful new experiences with his grandparents that make it hard to leave. (Preschool–grade 3)

Marisol McDonald and the Clash Bash, by Monica Brown, illustrated by Sara Palacios. Bilingual (English/Spanish). Marisol McDonald’s birthday is coming up, and she will be 8. As Marisol and her friends and family prepare for the celebration, she thinks of her greatest wish: for Abuelita to visit from far away.

How To Meet Software Testing Objectives

Linda G. Hayes

I was rendered speechless when a fellow professional said, in all seriousness, she was going to discard the majority of her regression tests because they had failed to find errors. After I recovered my composure–and my voice–I asked why she was considering such a thing, to which she confidently replied, Well, so-and-so says tests that don’t find problems aren’t worthwhile.

As it happens, the crazy claim turns out to be based on the earliest and most commonly quoted definition of software testing. Published in Glenford Myers’ 1977 book, The Art of Software Testing, the definition states: The purpose of testing is to discover errors. Testing is the process of trying to discover every conceivable fault or weakness in a work product.

Based on this found meaning, I can see where my colleague and her informant got the idea that tests that find no errors have no value. I can also see why software testers might rival dentists for having the top depression and suicide rates in all professions.

Proving a Negative

Simply finding errors is an unacceptable purpose for software testing. The approach requires software testers to prove a negative–there are no more errors to find. To demonstrate this, they must know how many errors there are to begin with and where the errors are. If we knew that, we would not need to test; we would just need to fix the errors.

Furthermore, if you don’t know how many errors exist, how do you know when you will be finished testing? How can you measure your tests’ effectiveness? Does this mean as you contribute to the overall improvement of the software development process, your effectiveness as a tester declines as well?

Proving the Pointless

Ironically, the true meaning of the term regression testing is to look for software functionality that used to work but no longer does, i.e., the software has regressed. But, based on Myers’ definition, there is no point in running a test that has found no errors, so once a software function works it is immune from further testing. Yet, the functionality that no longer works following a regression test poses the greatest risk, since it is still in use. The new functionality that doesn’t work may be irritating, but it is probably not devastating.

Proving Progress

To give credit where credit is due, more recent authors have improved upon the no errors-no value testing definition. In Software Test Automation, written by Mark Fewster and Dorothy Graham in 1999, the purpose of software testing is to give increased confidence in those areas of the product that work and to document issues with those areas of the product that do not work. Notice this terminology introduces the value of establishing what does work as well as what doesn’t.

Similarly, the most recent glossary of standards from the British Computer Society Specialist Interest Group in Software Testing (BCS SIGIST) defines testing as the process of exercising software to verify that it satisfies specified requirements and to detect errors. Ah, now we’re getting somewhere. The concept of requirements–you know, the reason we developed the software in the first place–is finally becoming part of the definition.

I wonder how significant it is that Mr. Fewster and Ms. Graham both hail from the United Kingdom, as, of course, does the British Computer Society. Perhaps we can persuade them to colonize the software testing industry here in the United States?

While it may seem academic to obsess about how software testing is defined, the impact is highly practical. Well-meaning experts–who espouse definitions that lead testers to discard tests that work–are setting the testers (and their companies) up for failure. If software isn’t proven to do the basics, who cares whether it fails to do the obscure?

How To Connect Gopro To Laptop

The most popular action camera device right now is the GoPro. It can take both videos and pictures in extreme environments without suffering major damage. Once the content is added to the GoPro, users will want to export all photos and videos to another device, for example, a Windows PC. Now, the question is, how can we connect a GoPro to a Windows computer and siphon off all the video and picture contents with ease? Well, you should worry not because we have all the information you need to keep on the right track.

How to connect GoPro to PC

We must point out that there are two ways to collect data from your GoPro. You can either connect the device via USB or attach the SD card to your computer.

Connect the GoPro to a computer via USB

Connect the GoPros SD card to your computer

1] Connect GoPro to computer via USB

The first thing to do is to connect the GoPro to your computer. This is pretty straightforward, so let us discuss how to get it done in the easiest way possible.

Begin by pressing the Power/Mode button to boot the GoPro.

Ensure the Wi-Fi is turned off on GoPro HERO3+ and older devices.

Once done, locate the USB port on the GoPro.

The port is usually located on the side of the device.

Connect the USB to the GoPro, then connect the other end to your computer’s USB port.

If the connection is made properly, a USB icon should show up on the screen of the camera.

Now, if you want to have the GoPro automatically open the folder with your files when connected to your computer, then make use of the AutoPlay feature.

The AutoPlay feature is quite useful because it makes it possible for the user to choose what happens when a third-party device is connected to Windows. For example, you can make it so that whenever your GoPro is connected, it will automatically open the video or image folders.

Use the Auto Launch/AutoPlay feature

Let us look at how to get this done in the easiest way possible right now.

Connect your GoPro to the computer via USB.

A small pop-up will appear at the left of your screen.

Windows will now automatically connect to the GoPro.

From now on, whenever the same device is connected to your computer, it will automatically direct the user to the folder containing the files.

2] Connect the GoPro’s SD card to your PC

If you do not have a USB lying around but rather an SD card reader, then this solution is perfect.

Remove the SD card from the GoPro.

If your computer does not have a built-in SD card reader, then connect a third-party reader to the device.

From there, slide the SD card into the reader.

In just a few seconds you should now be able to view the contents on the SD card directly from your Windows 11/10 computer.

Change AutoPlay settings

If you are not pleased with how the AutoPlay feature is working after a period of time, then you can adjust it.

Press the Windows key + I to launch the Settings app.

Scroll down and select AutoPlay.

From there, you can change the settings to what fits your needs, or turn it off entirely.

Why won’t my GoPro connect to my computer?

There are several reasons why your GoPro fails to connect to your computer. The camera itself could be the problem, so if that is the case we suggest removing the battery and the SD card, then reattaching them again before connecting to the computer. Furthermore, you could try connecting the GoPro to a different computer.

Can I connect my GoPro directly to my computer?

Yes, it is possible to connect a GoPro directly to a Windows 11/10 computer. This is possible because the device comes with support for USB, so all you have to do is connect the cable to the GoPro, then plug the other end into the USB port on your computer, and that’s it. However, if you do not have the USB cable with you, you can use the memory card to get the footages. The easiest way to view and manage videos on a GoPro is to use the software known as GoPro Quik for Desktop. Once up and running, you can watch and manage MP4 and HEVC video files. Bear in mind that HEVC requires a competent graphics card to play videos smoothly.
