![]() ![]() To make this happen, you can use Continuous Integration (CI) to run your tests on multiple machines. Since running all tests in a row can take a long time, Cypress has a feature to run tests at the same time and save time and money. Here, we will demonstrate parallel test execution with Cypress, a front-end testing tool built on JavaScript. Overcome QA challenges Understanding Cypress Test Execution Maintaining a parallel testing infrastructure can be complex and require ongoing maintenance and support to ensure that it is functioning correctly. When running multiple tests at the same time, compatibility issues can arise between different tests and the environment in which they are being run, leading to inaccurate test results. While parallel testing can reduce the cost per test, the overall costs associated with setting up and maintaining a parallel testing infrastructure can be significant. Parallel testing can be resource-intensive, requiring significant processing power and memory to run multiple tests at the same time. Parallel testing may require specialized hardware or virtual machines, which can be expensive to purchase and maintain. ![]() When running multiple tests at the same time, there is a higher potential for test failures and errors, which can impact the accuracy of test results. Parallel testing requires complex test management and coordination, including the allocation of resources, the scheduling of tests, and the management of multiple test environments. While there are plenty of advantages of parallel testing, it comes with its own set of challenges too. What are the Parallel Testing Challenges? Parallel testing allows the effective utilization of available testing resources, including hardware and virtual machines, to complete tests more efficiently. Quality assurance teams can improve their processes by performing more tests within a shorter span of time, thus having more time to identify potential bugs and loopholes. With quick reporting and feedback, communication is enhanced between the teams. Furthermore, cloud-based testing grids allow for tests to be run at a high level of parallelism, significantly lowering the cost per test.įor continuous integration and delivery, opting for parallel test execution allows the QA teams to run tests as soon as the developers have submitted the new code updates. Renting testing time on cloud services is a more cost-effective alternative to constructing and maintaining an in-house testing infrastructure. This increased test coverage reduces the chances of releasing the product with any type of bugs and defects. You can test across different devices and combinations, such as desktop OS/browser combinations together. If a test takes one minute across 10 devices, with parallel test execution, you can complete the test in one minute, hence speeding up the process and saving you time. The key benefits of parallel testing are listed as follows: Now that we have explored the meaning and definition of parallel testing, we can go through the advantages it offers. What are the Benefits of Parallel Testing? Verifies if the data format between the two versions has changed.Ensures the integrity of the new application.Ensures consistencies and inconsistencies are the same between the old and the new version.Ensures that the new version of the application performs correctly.The main characteristics of Parallel Testing are: Depending on the requirements of the project, QA teams can perform parallel test execution on multiple virtual machines, browser divides, and processors. By running tests in parallel, teams can reduce the time it takes to get feedback on the quality of their code, which can help to accelerate software development and delivery. Parallel testing is often used in CI/CD pipelines to speed up the testing process and make the pipeline more efficient. This can be achieved by executing tests on multiple physical or virtual machines or by dividing the tests into smaller chunks and running them in parallel on the same machine. The goal of parallel testing is to reduce the time it takes to run a suite of tests by dividing the tests into smaller groups and running them in parallel. ![]() Parallel testing or parallel test execution is a software testing approach in which multiple tests are run at the same time simultaneously.
