How to launch properly php cli script in phpunit test?

Question

I need to test some php cli script which uses stdout, stderr and return error code.

exec seems that it does not return stderr.
system does not return stdout (only last line), stderr.

I would advice proc_open then. It's a bit unwieldy though :) — Ja͢ck

proc_open could be used.

File: script.php

echo 'Standart output'; //stdout

error_log('Error output'); //stderr

exit(1); //return

File: test.php

<?php

$descriptorspec = array(
    1 => array("pipe", "w"), // stdout is a pipe that the child will write to
    2 => array("pipe", "w") // stderr is a pipe that the child will write to
);

$process = proc_open('php script.php', $descriptorspec, $pipes);
if (is_resource($process))
    {
    echo 'stdout: ' . stream_get_contents($pipes[1]) . PHP_EOL;
    fclose($pipes[1]);

    echo 'stderr: ' . stream_get_contents($pipes[2]) . PHP_EOL;
    fclose($pipes[2]);

    $return_value = proc_close($process);
    echo 'return: ' . $return_value . PHP_EOL;
    }
