PHPUnit - 'No tests executed' when using configuration file

Question

The Problem

To improve my quality of code, I\'ve decided to try to learn how to test my code using Unit Testing instead of my mediocre-at-best testing solutions.

Answer 1

Came late to the party, but this info may help others.

Above solutions did not work for me. As of Laravel 7.x, by default, PHPUnit executes only PHP files which are suffixed with "Test.php". For example if you create a test, naming it CreateUser will not work, whereas naming it CreateUserTest will work.

To overcome the limitation, go to phpunit.xml and modify suffix attribute from directory elements:

...


    
    ./tests/Unit




    
    ./tests/Feature


...

This will instruct PHPUnit to run all files with .php extension from directories. Note to clear app's cache after updating phpunit.xml:

php artisan config:cache
