Setting Up Selenium with aqua for Automated Testing

This guide will help you set up Selenium with aqua to run automated tests in your development environment or BrowserStack. Follow the steps carefully to ensure all components are correctly configured.

Prerequisites

Ensure you have the following ready before starting the setup:

  • A running aqua PowerShell agent: here the article

  • Java JDK installed on the server where the agent is running

  • Selenium, JUnit, Hamcrest, and Apache Commons IO libraries downloaded: you can find the zip. File here:

30MB
SeleniumJunitLibs.zip
archive

  • Aqua test case created with necessary test data for browser and OS configurations

  • Downloaded and installed browser extension Selenium IDE.

Steps to Set Up and Execute Tests

1. Setting Up the Environment

Please make sure you place the files in proper directory (within the powershell agent folder as in the screenshot below).

  1. Install Java JDK:

    • Download and install the latest version of Java JDK on the server running the PowerShell agent.

  2. Download Selenium:

    • Download the Selenium Java client library from Selenium's official website.

    • Extract the contents into a folder named Selenium inside the PowerShell agent directory.

  3. Download JUnit and Hamcrest Libraries:

  4. Create an empty folder "Temp".

  5. Download Apache Commons IO:

    • Download the org.apache.commons.io.jar and place it in the agent directory. Alternatively, ensure it is declared in the classpath.

  6. Run Selenium Server:

    • Download the Selenium standalone server from Selenium's official website.

    • Start the server with the command:

      java -jar selenium-server-4.23.0.jar standalone

2. Configuring aqua

  1. Login to aqua:

    • Access your aqua account and log in.

  2. Create a Test Case:

    • Navigate to the test cases section and create a new test case.

  3. Add a Test Step:

    • Inside the test case, create a new test step.

  4. Add PowerShell Automation:

    • Configure the test step to use PowerShell for automation.

  5. Upload PowerShell Script:

    • Copy the PowerShell script contained in execute.ps1 to the aqua PowerShell automation step.

  6. Upload Java Files:

    • Upload TestLoginTest.java as attachment to the PowerShell step. This file contains the test logic and logging utility.

3. Setting Up Test Data

  1. Add Test Data to the Test Case:

    • Include the following test data parameters to control the OS and browser configurations:

      • BrowserName

      • BrowserVersion

      • OS

      • OS_Version

    • These parameters are used in TestLoginTest.java to specify which environment the test should run on.

4. Executing the Test

  1. Start the Powershell agent.

  2. Run the Selenium IDE browser extension.

  3. Start the java server using cmd.

  4. Compile the Java Files:

    • Ensure the PowerShell script (execute.ps1) compiles the Java files using the javac command with the appropriate classpath that includes all required libraries and classes.

  5. Run the Test:

    • Execute the test through the aqua interface. The PowerShell script will run, compiling and executing the Java test files.

Example PowerShell Script (execute.ps1)

Notes

  • Ensure the paths in the PowerShell script are correctly set to the locations of the Selenium, JUnit, Hamcrest, and Apache Commons IO libraries.

By following these steps, you will successfully set up and execute Selenium tests within the aqua environment.
