PHPUnit cannot open file

Question

I've started learning how to use PHPUnit. However, I'm facing a problem which I have no clue how to solve.

I have a folder called lessons and inside there is a composer.json which I installed PHPUnit with. The output resulted in a folder called vendor and a sub-folder called bin which has the phpunit file in it.

In the cmd I typed: cd c:/xampp/htdocs/lessons/vendor/bin. Now the cmd folder sets to the same folder as phpunit. I've created a directory in lessons which I called tests (lessons/tests) which I store all of my tests in. I've created a file called PracticeTest.php with a very simple test script in it.

When I go back to the cmd and type phpunit tests I get cannot open file tests.php When I try to type phpunit PracticeTest I get cannot open file PracticeTest.php. When I try phpunit tests/PracticeTest (with .php or without) I get the same error that the file could not be opened.

My suspicious that it has something to do with that face that the cmd is pointing at the lessons/vendor/bin directory, but I'm not sure if it is really the problem or how to fix it.

just to arrange the paths:

• lessons\vendor\bin\
• lessons\tests\
• lessons\tests\PracticeTest.php

Thanks in advance!

Answer 1

This is what worked for me.

vendor/bin/phpunit ./tests/PracticeTest

Answer 2

I was getting the same, but if you type phpunit then tab you will see what directory you are in and it should autosuggest. Then navigate to your test file.

Answer 3

Go to path project:

D:\>cd www
D:\wwww>cd lessons

And execute:

D:\www\lessons>vendor\bin\phpunit tests
