Question

My test case looks like this:

class FooTest extends PHPUnit_Framework_TestCase {

    /** @covers MyClass::bar */
    function testBar()
    {
        $result = MyClass::bar();
        $this->assertSomething($result);
    }

}

Now, the test itself works perfectly fine but code coverage complains with:

PHP_CodeCoverage_Exception: Trying to @cover not existing method "MyClass::bar *//**".

Any ideas?

Correction

The issue was not within PHPUnit its self but withing PHP_CodeCoverage. The parsing logic is somewhat duplicated there and the PHPUnit fix (see below) didn’t help in that case.

The patch to fix this for 3.6 is:

diff --git a/PHP/CodeCoverage/Util.php b/PHP/CodeCoverage/Util.php

+        $docComment = substr($class->getDocComment(), 3, -2) . PHP_EOL . substr($method->getDocComment(), 3, -2);
 
         foreach (self::$templateMethods as $templateMethod) {
             if ($class->hasMethod($templateMethod)) {
                 $reflector   = $class->getMethod($templateMethod);
-                $docComment .= $reflector->getDocComment();
+                $docComment .= substr($reflector->getDocComment(), 3, -2);
                 unset($reflector);
             }
         }

I’ve opened a ticket for this at https://github.com/sebastianbergmann/php-code-coverage/issues/121.

Until this fix is released (and chances are that only happens for PHPUnit 3.7) you need to use the three liner.

Old Answer:

Old versions of PHPUnit didn’t work with one line annotations.

PHPUnit tried to find a class/method combination named: "MyClass::bar *//**"

Using a three line annotation works with all versions

/** 
 * @covers MyClass::bar 
 */

I fixed this PHPUnit 3.6.4.

See Issue 328.

From PHPUnit >= 3.6.4 your code should work just fine.
