Just like we have frameworks for writing software, we have frameworks writing test cases as well. As we are PHP developers, we will use a testing framework that is written in PHP or in which we can write test cases in PHP so that we can use it easily.
First of all, there are different testing frameworks that we can use in PHP, no matter which development framework we are using for application development. However, there are also testing tools that come with Laravel and Lumen. We can also use them for writing test cases. In fact, it will be easier to write test cases for Lumen but it will be Lumen and Laravel specific. Here, we will use a framework that you will be able to use outside the Lumen and Laravel ecosystems as well as for any PHP project, no matter which development framework you are using to write the code.
There are many different testing frameworks in PHP so how will we decide which one we want to use? We are going to use a framework that will not be so low...
