Ease App Testing with Small Tests l Bits&Bytes
Why smaller tests are better for app testing? Why it’s important to test your app as early as possible and preferably do it on real devices. Get your app tests right and smaller, while keeping high coverage and saving your time.
There are three things you should consider when figuring out the best types of test cases for your app.
Small tests are easier to create, maintain, read and modify
Smaller, focused test cases are easy to produce and maintain as the focus of those test cases is limited compared to large ones. Inputs and outputs are also simple and failing any part of the test are easy to observe.
The scope of testing is more accurate with small, targeted test cases
The number of test cases is high while the outcome of one test case can seem irrelevant. However, combining these results can give you a much better covered overall test of your app.
Small equals better reusability and easier to extend your arsenal of test cases
Smaller test cases work better as they are focused on a certain aspect of your application. Those smaller test cases are also easier to reuse – directly or with modifications – as there are fewer dependencies to other resources.
How to prepare for Splitting Test Cases Into Smaller Units?
Smaller tests are more likely reusable and are ready for mobile app testing on a real device cloud. Having a high number of test cases also means better coverage as anything can go wrong in large test cases and the rest of the test is not valid anymore.
Plan – And Split!
Start with planning your test cases and splitting them into scenarios. Every scenario should be created in a separate test method. Try to write your test cases so you test only one thing at a time.
Get Your Test Cases “Atomic”
A well-written test case could be described with five characteristics: Accurate, Efficient, Traceable, Repeatable, and Reusable.
FIRST – Fast, Independent, Repeatable, Small, Transparent
Your test cases should be very fast to implement and execute. All of it should be independent as well and easy to be repeated. Repeatability means that your test cases are ready to be executed at any time and doesn’t require any other test case. A smaller test case makes your test more predictable and obvious for what purpose it was created.
Shorter, smaller tests have made mobile app testing so much easier – despite the huge number of test cases. Choose the best way to run your tests.
