PHPUnit Selenium 服务器 - 更好/自定义错误处理？

发布于 2024-12-10 13:28:20 字数 88 浏览 1 评论 0原文

有没有办法让 PHPUnit 在发生错误后继续？例如，我有一个大型测试套件（400 多个步骤），我希望如果没有找到某个元素，它不会阻止我的脚本的其余部分继续执行。

我们在 Selenium 测试中做了同样的事情。您需要捕获因断言失败而引发的异常，唯一的方法是创建一个重写断言方法的自定义测试用例基类。您可以存储失败消息并在最后使用测试侦听器使测试失败。

我面前没有代码，但它非常简单。例如，

abstract class DelayedFailureSeleniumTestCase extends PHPUnit_Extension_SeleniumTestCase
{
    public function assertElementText($element, $text) {
        try {
            parent::assertElementText($element, $text);
        }
        catch (PHPUnit_Framework_AssertionFailedException $e) {
            FailureTrackerListener::addAssertionFailure($e->getMessage());
        }
    }

    ... other assertion functions ...
}

class FailureTrackerListener implements PHPUnit_Framework_TestListener
{
    private static $messages;

    public function startTest() {
        self::$messages = array();
    }

    public static function addAssertionFailure($message) {
        self::$messages[] = $message;
    }

    public function endTest() {
        if (self::$messages) {
            throw new PHPUnit_Framework_AssertionFailedException(
                    implode("\n", self::$messages));
        }
    }
}

We do the same thing in our Selenium tests. You need to catch the exceptions thrown for assertion failures, and the only way to do that is to create a custom test case base class that overrides the assertion methods. You can store the failure messages and fail the test at the end using a test listener.

I don't have the code in front of me, but it was pretty straight-forward. For example,

abstract class DelayedFailureSeleniumTestCase extends PHPUnit_Extension_SeleniumTestCase
{
    public function assertElementText($element, $text) {
        try {
            parent::assertElementText($element, $text);
        }
        catch (PHPUnit_Framework_AssertionFailedException $e) {
            FailureTrackerListener::addAssertionFailure($e->getMessage());
        }
    }

    ... other assertion functions ...
}

class FailureTrackerListener implements PHPUnit_Framework_TestListener
{
    private static $messages;

    public function startTest() {
        self::$messages = array();
    }

    public static function addAssertionFailure($message) {
        self::$messages[] = $message;
    }

    public function endTest() {
        if (self::$messages) {
            throw new PHPUnit_Framework_AssertionFailedException(
                    implode("\n", self::$messages));
        }
    }
}

有一个更好的方法可以做到这一点。您可以只重载一个方法：runTest()，而不是重载每个 assert*() 方法。它针对每个断言，并且可以捕获异常：

abstract class AMyTestCase extends PHPUnit_Framework_TestCase
{
    public function runTest()
    {
        try {
            parent::runTest();
        }
        catch ( MyCustomException $Exc ) {
            // will continue tests
        }
        catch ( Exception $Exc ) {
            if ( false === strpos($Exc->getMessage(), 'element not found') ) {
                // rethrow:
                throw $Exc;
            }
            // will also continue
        }
    }
}

There is a better way to do this. Instead of overloading every assert*() method you can overload just one method: runTest(). It is for each assertion, and exceptions can be caught:

abstract class AMyTestCase extends PHPUnit_Framework_TestCase
{
    public function runTest()
    {
        try {
            parent::runTest();
        }
        catch ( MyCustomException $Exc ) {
            // will continue tests
        }
        catch ( Exception $Exc ) {
            if ( false === strpos($Exc->getMessage(), 'element not found') ) {
                // rethrow:
                throw $Exc;
            }
            // will also continue
        }
    }
}
