Parallel Testing Execution In Selenium

If you are the ones lagging with your software testing, you better update your skills. There is no denying the importance of testing and its positive impact on software quality. But you can significantly enhance your testing speed by just knowing the definition of parallel testing execution.  

However, with the increasing diversity in the software testing industry, it is becoming harder for software testers to keep up. Parallel testing is helpful in this situation. 

The problem with this approach is limiting your potential to find application bugs. A better system would be to use a tool that can test across multiple platforms, like selenium. Selenium is a prominent open-source testing automation tool in the testing community. 

Selenium provides tools that allow enterprises to integrate test automation into the CI/CD pipeline and conduct Selenium parallel execution on many devices and browsers operating on different platforms. Selenium is all about explaining the definition of parallel testing execution in multiple ways through its tools! 

Parallel testing is the best way to increase your workflow. It is a testing approach that helps you increase your team's productivity by allowing them to test more things simultaneously. This way, you can be sure that your end users will be served with the best quality product.

Definition of Parallel Testing Execution?

Parallel testing is one of the most popular approaches to software testing. It is a testing strategy that allows you to run tests in parallel on different platforms, browsers, and devices. This way, you can be sure that you are testing the maximum number of bugs in the minimum possible time. 

It is a testing strategy that allows you to test more things simultaneously. This way, you can be sure that your end users will be served with the best quality product. In other words, parallel testing is a process of simultaneously testing more than one scenario. 

And when it comes to parallel testing in selenium, you can perform it in two ways: via the built-in Selenium test editor or the API. The definition of parallel testing execution in selenium will be elaborated on in the further article.

Guide to Perform Parallel Testing Execution in Selenium 

The traditional approach to running parallel tests is to use the test editor. This approach is suitable for static tests because it allows you to fail safely and keep working on your code. To run tests in parallel in the test editor, you run multiple instances of the selenium test browser on different browsers/devices. 

If your project requires large-scale test automation, you should use the API to perform parallel testing in selenium. You can run tests in parallel on any number of devices and browsers using the API. This way, you can be sure that your tests are executed in the most efficient way possible.

To execute and perform parallel testing in selenium, you need to use the parallel attribute, which can accept four values, i.e., tests, classes, methods, and instances.

1. Tests  

All test cases within the Testing XML file's test> tag will execute in parallel.

2. Classes  

All test cases included within a Java class will execute parallel 

3. Methods 

All methods with the @Test annotation will run in parallel. 

4. Instances 

Test cases in the same instance will run concurrently, but two methods from distinct instances will run on separate threads. 

This approach requires a lot of coordination among the test engineers to ensure they run the tests in parallel and in the correct order. It is also important to note that running multiple instances of selenium can only increase the number of possible tests that can be run. 

Does Parallel Testing Save Execution Time? 

Parallelization is the technique of performing several automated test cases concurrently rather than running single tests sequentially. Parallel testing allows organizations to significantly reduce the time it takes to perform automated tests while substantially increasing the breadth and scale of those tests. 

Because there is a clear correlation between the number of concurrent executions and the time it takes to execute the test suite, the ROI is instant and easily quantifiable. 

Now, Assume a team has a suite of 100 automated tests, each of which takes an average of one minute to execute. If the test suite is performed consecutively, it will take 100 minutes to complete. 

However, if that team splits the same test suite across ten parallel runs concurrently, the execution time might be reduced to just 10 minutes. As a result, the developers regain control for a substantial period. Until now, you must know that parallel testing saves execution time. 

Benefits of Parallel Testing Execution in Selenium 

Continuous integration requires testers to create separate test scripts for each distinct feature. The scripts will take time to run, and Parallel Testing is the only method to speed up testing while conducting other QA duties. 

As a result, parallel testing using selenium becomes a critical step toward an automated browser testing strategy. Let us look at some of the advantages. 

1. More Test Coverage 

Parallel testing in selenium allows for greater test coverage in less time while maintaining quality by offering automated cross-browser testing. Parallel testing is a speedier method of testing than sequential testing. 

Parallel testing eliminates the need to run the test several times for different operating systems and browsers. Instead, numerous parallel tests can run at the same time. 

2. Reduce Testing Time 

Parallel testing reduces testing time, allowing the QA team to focus on critical duties such as QA strategy. Parallel testing, as opposed to sequential testing, will enable tests to be executed on numerous machines at the same time, lowering testing time. 

Furthermore, the latter eliminates the possibility of human error, ensuring that quality is maintained. Sequential testing is unquestionably a thorough automated browser testing approach. 

However, unlike parallel testing, it is neither productive nor rapid. And as mentioned earlier, it certainly increases the testing speed by two times.

3. Cost-Effectiveness 

Sequential testing is a time-consuming procedure that necessitates constant development, maintenance, and updating of the test environment. Managing all of these aspects, in addition to the knowledge, would significantly increase the cost of the QA department.

Parallel testing, on the other hand, is automated and cloud-based in selenium. As a result, maintenance is not necessary because the cloud infrastructure is always up to date with the latest developments.

Frequently Asked Questions (FAQs) 

Q1. What is an example of a Parallel Testing definition Approach? 

Parallel testing is a method of using automation testing capabilities by allowing the execution of the same tests in various settings, actual device combinations, and browser configurations at the same time. Parallel testing's overarching purpose is to reduce time and resource constraints. 

Q2. Definition Of Parallel Testing Execution? 

Selenium parallel execution enables organizations to execute tests on several devices and browsers in parallel, dramatically reducing testing timelines. Parallel testing is a test automation method in which test cases are run on many browsers, operating systems, and devices at the same time.
