Unit testing of functions

I have got a PHP file in which there are some functions (not included in a class). I am using PHPUnit to testing. When I try to generate in a simply way a test file from a file containing functions, the log says:

Could not find class...

Is there any possibility to test functions which are not methods?

Yes, you can with something like this:

includes/functions.php

function my_function() {
    return true;
}

tests/MyFunctionTest.php

require_once '../includes/functions.php';

class MyFunctionTest extends PHPUnit_Framework_TestCase
{
    public function testReturnValue()
    {
        $return_value = my_function();
        $this->assertTrue($return_value);
    }
}

So as long as your function is within scope you can call it from your test method just like any other PHP function in any other PHP framework or project.

If I'm right then PhpUnit works only with classes hence methods. So just convert them into the methods for testing purpose. Shouldn't be hard.
