Parallel testing is a widely used, highly efficient software testing technique that you surely use most of the time, but may have a little in-depth idea about it. So, here we are going to focus on knowing it in detail.
Parallel testing is the method of running multiple test cases parallelly at once to test multiple applications or their components in a simultaneous order to reduce overall testing time. As this process sounds so simple, it is actually quite easy to perform. You just need to use an efficient test automation tool like Preflight to take care of everything.
However, you must have some operational concept about this important topic to achieve better results. Hence, let’s get started with it.
Parallel testing is indeed a highly efficient approach, but if we consider it more technically, the following points are the reasons to prioritize it.
As you know, testing means confirming that the software as well as all its components are working as expected. Hence, in parallel testing, what you need to do is that you have to run two or more versions of the same software concurrently with the same input or test methods.
Now, while parallelly running multiple versions of the software leads you to test the correctness of those versions, to check the cross-browser & cross-platform compatibility of one single version of an application, you have to run that version simultaneously on different devices and different browser-OS combinations.
Though parallel testing is an overall efficient approach to software testing, there are a few ideal situations where parallel testing is the most effective way to achieve the best results. Let’s check them out below.
The widely used effective approach to perform parallel testing is creating several projects to test different parts of the application and one large project to run all those small projects. Those small projects are called Slave projects and the large one is called master project.
Some best practices and tips & tricks for achieving the best results through parallel testing are mentioned below.
While running the parallel testing cycle, remember to measure the results of both the new and legacy systems line by line with the differences highlighted. Also, define every captured difference as per the type of error.
Parallel testing has gained popularity for its prime benefit of accelerating execution across multiple versions.
However, it also offers a number of benefits that we have jotted down below -
Let’s elaborate on the prime benefit of parallel testing. Accelerating execution lets you significantly save a lot of time. For example, if you have to run 100 tests while each one of them takes 2 minutes to get executed, and if you try to run them one by one synchronously, it will take you 200 minutes to complete running them. But, parallel testing can allow you to run all the 100 tests simultaneously, and you can complete running them in 2 minutes. So, when you are performing tests on a large scale, parallel testing can save you a lot of time.
You surely know how important it is for a tech business to achieve as much test coverage as possible. Parallel testing is one of the most efficient approaches that significantly improve the overall test coverage.
As it allows you to test across multiple devices and multiple browser-OS combinations at the same time, you become capable of achieving remarkably high test coverage in much less time while you can also ensure that your application is compatible with every environment and every situation.
Testing often becomes a bottleneck of DevOps. While the long & time-consuming traditional testing process does nothing to get rid of the bottleneck, parallel testing exempts you from that hassle. It accelerates testing and lets you ensure great product quality while the product is already live.
Besides allowing you to execute multiple tests on different devices and environments at the same time, parallel testing also enables you to fix the bugs during the test sprint. That makes it possible for the developers to focus on creating new features rather than staying stuck with testing the existing ones.
Parallel testing sounds like a very simple term, but in terms of significance, it holds a highly important place among efficient software testing strategies. This article provides you with an in-depth understanding of it and lets you know how it helps you in improving your overall testing efficiency. So, we suggest you carefully go through every detail and acknowledge yourself with a crucial method of achieving higher test coverage.
Also, you must know that parallel testing can be effectively implemented only when you use an advanced testing tool that allows you to test your product across multiple platforms and environments. And, we must mention that Preflight is one of the most renowned advanced AI-based test automation tools that can fulfill all your testing needs within seconds. It has gained and held its popularity by allowing everyone to create, run, and manage complex tests regardless of their coding knowledge. You can get detailed information about the advantages of using this tool from the article “10 Amazing Software Testing Benefits From Preflight In 2022”.
