我目前正在加入一个刚加入的项目的PHPUnit。运行PHP单元给了我以下结果：
PHPUnit 4.6.10 by Sebastian Bergmann and contributors.

#5 NotUnitTest.php(633): MyClass in NotUnitTest.php on line 73
存在致命错误，但事实是它没有显示它出现在哪个测试文件中。我现在想要的是排除导致致命错误的测试。因此，我想找到哪个测试文件和哪个行导致错误。我怎么能实现这样的目标呢？
答案 0 :(得分：0)
首先，您应更新PHPUnit。目前版本为6.5。
您的堆栈跟踪看起来很奇怪。通常，它包含完整路径，例如（我降级PHPUnit以获得可比较的结果）：
PHPUnit 4.6.10 by Sebastian Bergmann and contributors.
PHP Fatal error: Uncaught Error: Call to undefined function doIt() in /home/path/to/project/tests/unit/bug.php:6
Stack trace:
#0 /home/path/to/project/tests/unit/FooTest.php(8): Foo::buggy()
#1 [internal function]: FooTest->testFoo()
#2 /home/path/to/project/vendor/phpunit/phpunit/src/Framework/TestCase.php(865): ReflectionMethod->invokeArgs(Object(FooTest), Array)
#3 /home/path/to/project/vendor/phpunit/phpunit/src/Framework/TestCase.php(743): PHPUnit_Framework_TestCase->runTest()
#4 /home/path/to/project/vendor/phpunit/phpunit/src/Framework/TestResult.php(609): PHPUnit_Framework_TestCase->runBare()
#5 /home/path/to/project/vendor/phpunit/phpunit/src/Framework/TestCase.php(699): PHPUnit_Framework_TestResult->run(Object(FooTest))
#6 /home/path/to/project/vendor/phpunit/phpunit/src/Framework/TestSuite.php(722): PHPUnit_Framework_TestCase->run(Object(PHPUnit_Framework_TestResult))
#7 /home/path/to/project/vendor/phpunit/phpunit/src/Framework/TestSuite.php(7 in /home/path/to/project/tests/unit/bug.php on line 6
在这里，您可以清楚地看到错误发生在bug.php的第6行，该FooTest.php来自Foo::buggy()中第8行，并且调用了NotUnitTest.php。
在此之后，您正在寻找的电话位于第272行的MyTool::Something('Hello World')，并在其中调用MyOutdatedPHPFile.php。
如果您无法解决堆栈跟踪中的奇怪输出（缺少的路径），您仍然可以使用IDE查找相关的测试文件。
在->methodName(中找到包含第73行的方法。然后让IDE搜索该方法的用法。如果您的IDE不支持使用率搜索，请更改IDE或使用users的文本搜索。在任何情况下，您都会获得一个包含相关方法调用的文件列表 - 其中一个是您正在寻找的文件。
