Question

I have been trying to echo stuff in my phpunit tests but no luck so far.

I read the documentation about the xml config file and apparently the debug parameter is what I am looking for. Unfortunately it still doesn’t work. Anyhow here is my xml config file:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit colors="true"
         processIsolation="true"
         verbose="true"
         debug="true">
</phpunit> 

Both processIsolation and verbose are accepted but debug is not.

The command actually works pretty fine when I directly pass it to phpunit like this:

phpunit --debug MyTest.php # here stuff is echoed correctly

but with the xml config file it looks like it is ignored.

Current versions of PHPUnit >3.6.4 (and all 3.5.* versions) will just print everything you echo in a test case.

<?php

class OutputTestCase extends PHPUnit_Framework_TestCase {

    public function testEcho() {
        echo "Hi";
    }   
}

produces:

phpunit foo.php 
PHPUnit 3.6.7 by Sebastian Bergmann.

.Hi

OK (1 test, 0 assertions)

So if you are on an old 3.6 version just upgrade 🙂
