echo in phpunit tests [duplicate]

Answer 1

In case your test takes a long time and you would like to see the output during the process, add the following method to your test class:

protected function prontoPrint($whatever = 'I am printed!')
{
    // if output buffer has not started yet
    if (ob_get_level() == 0) {
        // current buffer existence
        $hasBuffer = false;
        // start the buffer
        ob_start();
    } else {
        // current buffer existence
        $hasBuffer = true;
    }

    // echo to output
    echo $whatever;

    // flush current buffer to output stream
    ob_flush();
    flush();
    ob_end_flush();

    // if there were a buffer before this method was called
    //      in my version of PHPUNIT it has its own buffer running
    if ($hasBuffer) {
        // start the output buffer again
        ob_start();
    }
}

Now whenever you call $this->prontoPrint($variable) inside your test class, it will immediately show the text in the console. I used this php.net comment to write the function.
