Displaying Result and Expected values of an Assertion in CakePHP testing - unit-testing

Question

Does anyone know if there is a way to force CakePHP TestSuite to view the Expected and Result values of an assertion when it fails? Typical PHPUnit tests are showing it by default in the output but not Cake's TestSuite (which uses PHPUnit). A side from that, when i debug a test case in NetBeans i get some kind of Socket Exception whenever i try to set a watch for a variable, and it only happens in CakePHP test cases, it works fine in evry other source file. Is there a solution for this aswell?

check out

basically, you can extend the TestCase class and make your own additional methods like
public function details($is, $expected) {
echo 'is:' . $is; echo '<br />';
echo 'expected: ' . $expected; ob_flush();
}
and call it internally or sth on fail.
or you just debug() everywhere.

Answer 2

Ok I somehow worked it out tho the solution will be wiped when u update the Cake Library files. You need to edit the file lib\Cake\TestSuite\Reporter\CakeHtmlReporter and change the method:
public function paintFail($message, $test)
{
$trace = $this->_getStackTrace($message);
$testName = get_class($test) . '(' . $test->getName() . ')';
echo "<li class='fail'>\n";
echo "<span>Failed</span>";
echo "<div class='msg'><pre>" . $this->_htmlEntities($message) . "</pre></div>\n";
echo "<div class='msg'>" . __d('cake_dev', 'Test case: %s', $testName) . "</div>\n";
echo "<div class='msg'>" . __d('cake_dev', 'Stack trace:') . '<br />' . $trace . "</div>\n";
echo "</li>\n";
}
to:
public function paintFail($message, $test) {
$trace = $this->_getStackTrace($message);
$testName = get_class($test) . '(' . $test->getName() . ')';
echo "<li class='fail'>\n";
echo "<span>Failed</span>";
echo "<div class='msg'><pre>" . $this->_htmlEntities($message->getComparisonFailure()->toString()) . "</pre></div>\n";
echo "<div class='msg'>" . __d('cake_dev', 'Test case: %s', $testName) . "</div>\n";
echo "<div class='msg'>" . __d('cake_dev', 'Stack trace:') . '<br />' . $trace . "</div>\n";
echo "</li>\n";
}
And this will output you something like this when the assertion fails:
Failed asserting that two arrays are equal.--- Expected
+++ Actual
## ##
Array (
- 0 => 'Crypto3DS'
- 1 => 'Zlib'
+ 1 => 'Crypto3DS'
+ 2 => 'Zlib'
)
Faster testing in Cake Yeppie :D
