Around 44% of the mobile app user uninstall the app if the app doesn’t work properly. Around 33% will switch to your competitor if they are not happy with the performance of the app. You can bend these figures in your favor with a smart testing strategy and using the right type of testing for the right purpose.

Usually, mobile app testing is considered to be a time taking process. This is why more focus should be on automating the testing process and perform manual testing only where it’s necessary. Let’s have a look at how we can do that by performing parallel testing.

What is Parallel Testing?

Running multiple tests on multiple OS browser combinations at the same time is called parallel testing. The test scripts are created to automate parallel testing and it is usually done on a virtual machine. In parallel testing, two different versions of the app are run with the same input to ensure that the system is capable of running the versions efficiently.

Why and When to do Parallel Testing

Parallel testing is done to make sure that the new version of the app is working correctly. It helps to make sure that the consistencies are the same in the legacy version and the new version. The testers need to ensure that data migration is done properly. The idea is to verify that the changes are done successfully and the users are getting a better experience.

It can be done when synchronization is needed on two systems and legacy data is transferred from one system to another. Parallel testing can be performed using online Android emulators or by using cloud-based mobile app testing services, as multiple devices are required.

Advantages of Parallel Testing

Wider Compatibility Coverage

As parallel testing takes less time, a lot of browser-OS combinations can be used to test the app on multiple devices. This is good for your app as you will be able to find and fix any bugs in the app and there will not be any compatibility issue.

Continuous Integration and Delivery Optimized

Rapid and frequent testing is the key to achieve Continuous Integration and continuous delivery. Pre-scripted testing saves time and also the test data from the detailed reports can be used to quickly rectify the issue.

Sequential to Parallel Test

There are many frameworks for parallel testing which can cater to all your testing routine. You can change from sequential to parallel testing without sacrificing the quality, strategic targets and testing goals. You can transition to it in steps and integrate it into your development.

Fast Testing

As opposed to sequential testing, parallel testing can save time as concurrent runs can divide the time into fractions. So if you are running 10 test at a time on ten machines then the time taken is one-tenth of the time that will be spent on performing 10 sequential tests.

So you can run more tests faster and with the frequent release, you can fix the bugs faster. Parallel testing on cloud device can reduce investment, decrease the cost of lengthy test cycles and delayed the release. Most importantly it can affect the customer review of the product which is good in the long run.

Conclusion

To perform Parallel Testing you need to have complete knowledge of the product and date input with respect to the flow of product should be monitored. It is a great practice which is inevitable in most of the cases.
