unit-testing - 在 CakePHP 测试中显示断言的结果和期望值

Question

有谁知道是否有办法强制 CakePHP TestSuite 在失败时查看断言的预期值和结果值？默认情况下，典型的 PHPUnit 测试在输出中显示它，而不是 Cake 的 TestSuite（使用 PHPUnit）。另一方面，当我在 NetBeans 中调试测试用例时，每当我尝试为变量设置监视时，我都会得到某种 Socket 异常，并且它只发生在 CakePHP 测试用例中，它在每个其他源文件中都可以正常工作。这也有解决方案吗？

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

查看 http://www.dereuromark.de/2011/12/04/unit-testing-tips-for-2-0-and-phpunit/

基本上，您可以扩展 TestCase 类并制作自己的附加方法，例如

public function details($is, $expected) {
    echo 'is:' . $is; echo '<br />';
    echo 'expected: ' . $expected; ob_flush();

}

并在内部调用它或失败时调用它。

或者你只是到处 debug() 。
