为什么 PHPUnit 会尝试查找具有测试套件名称的文件?

2022-01-25 00:00:00 testing unit-testing php phpunit

我的 phpunit.xml 文件中有这个:

I have this in my phpunit.xml file:

<phpunit ...>
    <testsuites>
        <testsuite name="MyTests">
            <directory>../path/to/some/tests</directory>
        </testsuite>
    </testsuites>
    ... // more settings for <filter> and <logging>
</phpunit>

当我去运行它时，我得到了这个错误:

And when I go to run it, I get this error:

PHP fatal error: Uncaught exception 'PHPUnit_Framework_Exception'
with message 'Neither "MyTests.php" nor "MyTests.php" could be opened.'

为什么 PHPUnit 会给我这个错误，如果我给它一个目录来查找测试，为什么它会寻找MyTests.php"?

Why does PHPUnit give me this error, and why is it looking for "MyTests.php" if I gave it a directory in which to look for tests?

在相关说明中，当我在其他测试中添加更多 <testsuite> 条目时，PHPUnit 运行时不会出错.这是怎么回事?

And on a related note, when I add more <testsuite> entries with other tests, PHPUnit runs without error. What's up with that?

推荐答案

默认情况下，PHPUnit 会添加在 *Test.php 文件中找到的所有 *Test 类"(参见 PHPUnit 文档).如果它没有找到与该描述匹配的任何文件(例如，定义 SomeTest 类的 SomeTest.php 文件)，它会回退到基于测试套件的名称属性.

By default PHPUnit will add "all *Test classes that are found in *Test.php files" (see PHPUnit docs). If it doesn't find any files matching that description, (e.g. a SomeTest.php file defining a SomeTest class), it falls back to looking for a file based on the name attribute of the test suite.

解决方案是创建一个与该描述匹配的文件，以便 PHPUnit 不会退回到其默认的按测试套件名称搜索:

The solution is to create a file matching that description so that PHPUnit doesn't fall back to its default of searching by the testsuite name:

<?php
// in ../path/to/some/tests/SomeTest.php:
class SomeTest extends PHPUnit_Framework_TestCase {
    public function test() {
        //... test cases here
    }
}
?>

现在你应该可以运行 phpunit 没有错误了:

Now you should be able to run phpunit without errors:

$ phpunit
PHPUnit 3.5.14 by Sebastian Bergmann.

.

Time: 0 seconds, Memory: 10.75Mb

OK (1 test, 0 assertions)

如果 PHPUnit 能够找到匹配的测试用例以在其他套件下运行，则添加更多 testsuite 条目时它将正常工作.如果它找到要在任何测试套件中运行的测试，它不会通过 name 属性搜索它找不到任何东西的套件.

It will work without errors when you add more testsuite entries if PHPUnit is able to find matching test cases to run under those other suites. If it finds tests to run in any testsuite, it won't resort to searching by the name attribute for the suites it couldn't find anything for.
