Problems Unit Testing with Simpletest

I am using PHP and simpletest for unit testing. My tests work fine until I try and set the cookie

try{
    setcookie($name,$cookie,$cookie_expires );
}catch Exception($e){
  blah
}

The exception is thrown because simpletest has already written out header information so I get the following:

Unexpected PHP error [Cannot modify header information - headers already sent by (output started at /tests/simpletest/reporter.php:43)] severity [E_WARNING] in [blah_code.php line 280]

I've seen vague explanations on catching this with $this->expectException(new Exception()); but no further documentation or examples that work. Could someone provide a working example or point me to documentation? To be clear. This is NOT my code producing the output but rather SimpleTest.

One way to get around this is by using output buffering.

You can turn it on globally in PHP's configuration (and possibly in .htaccess), or you can use ob_start() and its related functions (ob_get_clean(), ob_end_flush(), etc). For example:

ob_start();
// your SimpleTest here.
// your header/ cookie manipulation here.

And then:

ob_end_clean(); // Stop buffering and dump everything (don't echo).
ob_end_flush(); // Stop buffering and echo out the buffer.
ob_get_clean(); // Stop buffering and return everything as a string.

Or any of the other related functions. I believe PHP calls ob_flush() at the end of a file if you don't.

You get this error when you have output before (header functions) setcookie($name,$cookie,$cookie_expires );.

Make sure you don't have any echos or html or text or anything(NOT EVEN A SPACE) before <?php of setcookie($name,$cookie,$cookie_expires );.
