Question

当其中一个测试失败时，您可以使用--stop-on-failure标志来打破单元测试。

有没有办法快速告诉PHPUnit重新运行此失败的测试，而是手动提供完整路径？

Answer 1

查看--filter cli选项。您可以在organisation docs和CLI Docs中找到示例。

- 过滤器

仅运行名称与给定模式匹配的测试。模式可以是单个测试的名称，也可以是与多个测试名称匹配的正则表达式。

假设您的广告phpunit Tests/和Tests/Stuff/ThatOneTestClassAgain::testThisWorks失败：

您的选择是：

phpunit --filter ThatOneTestClassAgain

和

phpunit --filter testThisWorks

或大多数其他有意义的字符串

我发现实现它的方式相当简单，但需要实现日志记录。您设置phpunit以登录到json文件。然后你将phpunit命令改为类似于：

cd /home/vagrant/tests && php -d auto_prepend_file=./tests-prepend.php /usr/local/bin/phpunit

这样做是在执行phpunit之前auto_prepend一个php文件。这样我们就可以捕获$ argsv并自动向phpunit提供所需的过滤命令。

<强>测试-prepend.php （确保修改json日志的文件路径）

        if($value === '--rerun-failures') {
            $has_rerun = true;
            unset($argv[$key]);
            break;

Since PhpUnit 7.3，您可以缓存测试结果，然后按缺陷排序测试。

在phpunit.xml中，启用cacheResults：

<?xml version="1.0" encoding="UTF-8"?>
<phpunit cacheResult="true"
         ...>

如果您不想编辑phpunit.xml，也可以使用--cache-results标志运行测试。

缓存结果时，PhpUnit将在运行测试后创建一个.phpunit.result.cache文件（请确保将此文件添加到您的（全局）gitignore文件中）。

您可以像这样运行测试以首先运行先前失败的测试：

phpunit --order-by=defects --stop-on-failure

在PHPUnit中重新运行上次失败的测试
