Test

What is this directory about

Put all your test files here so that the framework can find them when, for example, the flutter test command is executed. Every file also needs a suffix _test.dart to be successfully found. Stick to that pattern and you’ll have no problems.

It is considered good practice when your test folder structure matches your lib folder structure. This will speed up navigation inside the project for developers.
