PHPUnit print tests execution time

Question

is there a way to print the execution time of each test with PHPUnit?

Answer 1

Many of the current answers discuss how to access and analyze the duration times in the log file. I will share two ways to modify the CLI output in phpUnit version 3.7.38 (which is what Travis-CI uses for PHP by default), building on @edorian's incomplete answer.

Use a custom printer to override the CLI output. I can't find any documentation for printers but they appear to be supported. You can see which methods are available in the source code.

class TestDurationPrinter extends PHPUnit_TextUI_ResultPrinter
{
    public function endTest(PHPUnit_Framework_Test $test, $time)
    {
        printf("Test '%s' ended and took %s seconds.\n", 
           $test->getName(),
           $time
        );
    }
}

Then add these lines as attributes to phpunit in the phpunit.xml file:

printerFile="path/to/TestDurationPrinter.php"
printerClass="TestDurationPrinter"

You can also use the --printer CLI option but that doesn't play well with namespaces.

You can add to the CLI output, as opposed to overriding it, with a TestListener by implementing the PHPUnit_Framework_TestListener interface (this is the same interface that printers use). This will still print ., S, and F so be sure to account for that, if you desire.

class TestDurationListener implements PHPUnit_Framework_TestListener
{
    public function endTest(PHPUnit_Framework_Test $test, $time)
    {
        printf("Test '%s' ended and took %s seconds.\n", 
           $test->getName(),
           $time
        );
    }

    public function addError(PHPUnit_Framework_Test $test, Exception $e, $time)
    {
    }

    public function addFailure(PHPUnit_Framework_Test $test, PHPUnit_Framework_AssertionFailedError $e, $time)
    {
    }

    public function addIncompleteTest(PHPUnit_Framework_Test $test, Exception $e, $time)
    {
    }

    public function addRiskyTest(PHPUnit_Framework_Test $test, Exception $e, $time)
    {
    }

    public function addSkippedTest(PHPUnit_Framework_Test $test, Exception $e, $time)
    {
    }

    public function startTest(PHPUnit_Framework_Test $test)
    {
    }

    public function startTestSuite(PHPUnit_Framework_TestSuite $suite)
    {
    }

    public function endTestSuite(PHPUnit_Framework_TestSuite $suite)
    {
    }
}

In version 3.8 and above there is a PHPUnit_Framework_BaseTestListener that can be extended so that you only define the methods you want to override.

class TestDurationListener extends PHPUnit_Framework_BaseTestListener
{
    public function endTest(PHPUnit_Framework_Test $test, $time)
    {
        printf("Test '%s' ended.\n", $test->getName());
    }
}

To include your new listener, add these lines to your phpunit.xml file:
