What is parallel testing and how does it work?
To speed up test execution, many versions of an application are tested together with the same input on various systems in a process known as parallel testing. Parallel testing used to determine whether the latest iteration is more effective than the old iteration and to decide whether or not they behave similarly or differently. It is one of the many types of software testing processes that can be utilized.
How Does Parallel Testing Work?
A tester does parallel testing by running two or more software packages simultaneously while using the same source or testing procedures. As an alternative, numerous device combinations can execute the same version of the program simultaneously.
Benefits of Parallel Testing
Test execution across several versions being sped up is one of the major advantages of parallel testing. Given below are a few other advantages to note.
Broaden the Test Coverage
Another advantage of testing increased test coverage. You may test simultaneously on additional desktop OS/browser and mobile device combinations. Risk reduced and the likelihood of deploying with escaped problems decreased by increased test coverage.
Speed up the execution
Take this into consideration in terms of speed of execution. If a single test takes a minute to perform and you run ten tests simultaneously, it will take ten minutes to run all of the tests.
The test period reduced to only one minute if the same test done simultaneously on ten different devices. When evaluating at scale, this can result in substantial time savings.
Sooner bug fixes
Bug fixes may also made even during sprint rather than after thanks to parallel testing. As a result, developers no longer have to spend as much time correcting errors and can instead use that energy to innovate and design new features.
In these situations, testers must do testing to determine whether data migration was effective. Furthermore to see if the system functionality unaffected by the modifications in the latest version. The tester must check that modifications are done successfully, and the client is getting the desired result as per the specification.
Eliminate the bottleneck in testing
Testing is all too frequently the DevOps bottleneck. The entire cycle held up by laborious testing. In contrast, parallel testing speeds up testing and considerably lowers the risk of continual quality visibility by assisting you in removing the bottleneck.
Things to note during testing
You can easily execute testing by making numerous projects (called slave projects) that each test a separate component of the application and one project (called a master project) that runs all of the slave projects.
Parallel testing standards have two levels.
- Parallel test entry criteria
- The activities that must be completed before parallel testing may be effectively carried out are specified by the parallel test entry criteria.
Parallel test exit Criteria
The parallel testing stage is defined as having completed when certain exit conditions are met.
There are a few prerequisites that must met before testing can be performed.
- A parallel test cannot start until the environment has been set up.
- Every situation and prerequisite needs to be defined first.
- Effective data migration of both legacy and new data is required.
- The parallel exam is not finished until all exit requirements are met.
Wrapping up
Parallel testing increases test coverage and relevancy while shortening test duration and expense. It becomes crucial that software testers more knowledgeable about the application tested and capable of developing a testing strategy that works in conjunction with the current testing framework.
