How does parallel testing ensure comprehensive coverage across environments?

Parallel testing ensures comprehensive coverage across environments by allowing you to run multiple test cases simultaneously on different platforms, configurations, and devices. This approach offers several key advantages:Ā 

  1. Testing Efficiency: With parallel test execution, you can significantly reduce the time required to complete test cycles. This efficiency allows for more extensive testing within the same timeframe, ensuring that all necessary scenarios are covered across various environments.Ā 
  2. Consistent Validation: Parallel test execution in testing enables the simultaneous validation of software functionalities across different environments. This consistency ensures that the application behaves as expected under various conditions, identifying environment-specific issues that might otherwise go unnoticed.Ā 
  3. Resource Optimisation: Utilising multiple environments concurrently maximises resource utilisation, ensuring that hardware and software resources are effectively leveraged. This optimisation not only speeds up the testing process but also allows for more comprehensive testing by covering more ground in less time.Ā 
  4. Early Defects Detection: Running tests in parallel helps you detect defects and discrepancies early in the development cycle. This early detection allows for timely resolution, reducing the risk of critical issues persisting into later stages of development or production.Ā 

By using parallel testing, you can ensure that your software is rigorously tested across all relevant environments. How? We explain in the next sections.

What challenges does aqua cloud solve?

When testing a web or desktop application, you will inevitably need to execute your test cases in different environments that your application must support. For web applications, this could mean testing across different browsers or various versions of the same browser. For desktop applications, it might involve different operating systems (Windows, macOS, Linux) or different versions of the same OS (e.g., Windows 10 and Windows 11). These scenarios introduce significant complexity to your testing efforts:Ā 

  1. Managing Diversity: Effectively and conveniently managing the diversity of versions, environments, test cases, and test runs can be challenging and time-consuming.Ā 
  2. Extended Testing Cycles: More environments mean longer testing cycles as you need to run all or a portion of your tests in each environment. Therefore, the issue of parallel testing across different environments becomes highly relevant.Ā 

How aqua cloud simplifies parallel testing in various environmentsĀ 

So here it is: this section will demonstrate how aqua cloud specifically addresses these challenges and simplifies this stage of testing. Despite the complexity, a professional TMS like aqua can help you achieve seamless parallel testing effortlessly. Hereā€™s how, before we show it in our video guide:Ā 

Step-by-Step Guide to Parallel Testing with aqua cloudĀ 

Step 1: Identify the List of Environments
Determine the environments where you need to perform testing. For instance, if you are testing a desktop application (like “Calculator”, in our simple example) on Windows 10 and Windows 11, list these environments accordingly.Ā 

Step 2: Configure Agents for Each Environment
Set up an agent for each environment. For launching applications in Windows 10 directly from aqua, use a PowerShell agent for integration. Make simple adjustments to each agent to bind them to your aqua instance and specific project, then launch each agent in each environment.
Note: This preparation step is similar for other agents, such as a UnixShell agent for desktop applications or a Ranorex/Selenium agent for web applications, etc.Ā 

Step 3: Prepare Your Test Set
Select the test case or set of test cases that need to be executed in these environments and add them to a separate test scenario. Ensure your test data is ready and properly configured.
Step 4: Link Test Executions to Your Agents
Create a separate test execution for each test case in each environment and link it to the previously configured agents.
Step 5: Run Your Test Scenario
With everything set up, aqua allows you to run the tests sequentially or in parallel. If your test plan supports parallel execution, initiate the tests in parallel to save time and increase efficiency.
Step 6: Track Your Results
Navigate to the “Executions” section to collect the results of the entire test scenario. aqua cloud provides detailed insights into each test case, test steps, execution logs, and overall outcomes.

And here is the video explanation of what youā€™ll do (make sure you watch it till the end for full understanding):
