What is parallel testing?

Parallel testing is a semi-automated testing process that relies on cloud technology and virtualization to perform tests against several configurations at the same time. The goal of this process is to resolve the limitations of time and budget while still assuring quality.

How does selenium perform parallel testing?

Along with the parallel attribute, the thread-count attribute helps in defining the number of threads one wishes to create while running the tests in parallel. For example, in case one has three methods, with thread count as two, then during execution, two threads shall start in parallel with the corresponding methods.

What is parallel testing in testNG?

In testng. xml, if we set ‘parallel’ attribute on the tag to ‘tests’, testNG will run all the ‘@Test’ methods in tag in the same thread, but each tag will be in a separate thread. By using parallel execution, we can reduce the ‘execution time’ as tests are executed simultaneously in different threads.

Can we do parallel testing in selenium?

Selenium parallel execution enables organizations to simultaneously run tests in parallel on different devices and browsers to significantly shrink testing times. Parallel testing is a test automation method wherein test cases are simultaneously run on multiple combinations of browsers, operating systems, and devices.

Why do we use parallel testing?

Parallel testing is an automated testing process that developers and testers can launch multiple tests against different real device combinations and browser configurations simultaneously. The goal of parallel testing is to resolve the constraints of time by distributing tests across available resources.

Who performs parallel testing?

In parallel testing, a QA engineer executes two or more versions of a software at the same time using the same input or testing method. Alternatively, a single software version can be performed simultaneously on several devices or a combination of browsers and operating systems.

Why is parallel testing recommended?

The primary purpose of executing tests in parallel is to reduce the overall time and efforts of automated browser testing while ensuring a quality product by using a Selenium Grid. Similarly, if you had 4 parallel tests running, the total time would have chopped down to 30 minutes only and so on.

What are the advantages of parallel testing?

Benefits of Parallel Testing

• Speed.
• Cost-Efficiency.
• Better Coverage.
• Optimization of Your CI/CD Processes.
• Improvement of Testing Practices.
• Gradual Transition from Sequential Testing.
• Test in the Cloud-Based Environment.
• Avoid Dependencies Between Tests.

What is Maven Selenium?

SeleniumAutomation TestingTesting Tools. Maven is Yiddish Word which means Accumulator of Knowledge. Maven is a tool which is used for building and managing Java Based Projects. Basically to put it in simple words is a way to manage dependency for Java Based Project.

Can we run parallel tests without TestNG?

You need to write the logic to pass three instances of tests pointing to the hub in parallel for the node to work its magic. Or you can use JUnit or testNG which will do most of these for you.

Why do we parallel test?

Parallel tests consist of two or more parts that check separate parts or features of an application. These parts are executed on individual computers simultaneously. Parallel testing allows reducing the test time significantly and increase the testing efficiency.

How to run parallel tests with selenium?

How to run Parallel Tests with Selenium. There are situations where you want to run multiple tests at the same time. In such cases, one can use “parallel” attribute. The parallel attribute of suite tag can accept four values: The attribute thread-count allows you to specify how many threads should be allocated for this execution.

What is parallel testing in Web testing?

In parallel testing, we test different modules or applications on multiple browsers in parallel rather than one by one. The parallel test execution is different from sequential testing, where we test different modules or functionalities one after the other.

What is the difference between sequential and parallel testing?

The parallel test execution is different from sequential testing, where we test different modules or functionalities one after the other. Even in the case of testing applications on multiple browsers, tests are performed sequentially on various browsers.

Is your selenium testing solution scalable?

With the advancement in technology, testing solutions have become more scalable than ever, as organizations moved to Selenium test automation from manual testing. But, one area that most organizations are still struggling with is the scalability to run multiple tests in parallel.
