Codeigniter 4: run phpUnit from controller

Question

I'd want to run my tests from a controller and display the output in the browser.

I tried with this code:

<?php namespace App\Controllers;

class Home extends BaseController
{
/**
 * Run tests and display output.
 */
public function test(): string
{
    $out = [];
    exec('./vendor/bin/phpunit', $out, $ret);
    return implode('\n', $out);
}
}

But when I go to localhost:8080/Home/test it return an empty page.

The $ret variable contains 1 after the exec, and the $out array remains empty.

If I call ./vendor/bin/phpunit from the command line it works correctly.

I'm pretty sure that it's a matter of paths and maybe permissions. I tried also the paths ../vendor/bin/phpunit and ../../vendor/bin/phpunit but nothing changes.

UPDATE:

changing the content of the method to

return `./vendor/bin/phpunit`;

throws an exception because it return null instead of a string.

Putting phpunit and phpunit.bat inside the public folder and changing the code to

return `phpunit`;

return the string Could not open input file: [project path]\public\/../phpunit/phpunit/phpunit

UPDATE 2:

the last error is solved by copying the folder vendor/phpunit one level in the root of the project. But still it returns null.

exec, shell_exec etc. are disabled for security reasons. If you have root access you can enable them in the php.ini file (search disabled_functions), otherwise there is nothing to do.
