阅读 SDebug README 有如下说明

The name of the extension is sdebug instead of xdebug, if you want to use Phpunit CodeCoverage, you have to manually modify xdebug to be sdebug.

为了避免 swoole 的检测 xdebug 警告, 扩展注册的名称是 sdebug, 如果想使用 Phpunit CodeCoverage , 需要手动把检测 xdebug 的判断修改成 sdebug。

因此需要对如下文件进行修改

vendor/sebastian/environment/src/Runtime.php

 211       return ($this->isPHP() || $this->isHHVM()) && (extension_loaded('xdebug')|| \extension_loaded('sdebug'));

...
79        $this->pathCoverageIsMixedCoverage = version_compare(phpversion('sdebug'), '2.9.6', '<');
...
126        return 'Xdebug ' . phpversion('sdebug');

...
52                    phpversion('sdebug')
...
117        return 'Xdebug ' . phpversion('sdebug');

  • 修改完上述文件代码后修改 phpunint.xml

  • 去除 coverage 标签中 processUncoveredFiles="true" 否则会抛出异常

运行测试

co-phpunit -c phpunit.xml --colors=always --coverage-html ./runtime/codeCoverage

image

执行成功后 会在 ./runtime/codeCoverage 中生产对应测试报告

image

测试报告生产出来了,但是覆盖率始终未 0

cs-fix 会添加 @coversNothing 去除 test/Cases/ExampleTest.php中的 @coversNothing 再次执行 co-phpunit -c phpunit.xml --colors=always --coverage-html ./runtime/codeCoverage 就能正确的生产测试覆盖率报告了

与 Hyperf 2.0 差异

hyperf 2.1 对 phpunit 的依赖从 ^7.0.0 提升到 ^9.4 阅读 PHPunit 的 ChangeLog-8.5 可知 phpunit 支持了 xdebug 3

vendor/phpunit/php-code-coverage/src/Driver/Xdebug.php 被拆分分为了 vendor/phpunit/php-code-coverage/src/Driver/Xdebug3Driver.php vendor/phpunit/php-code-coverage/src/Driver/Xdebug2Driver.php

因此hyperf 2.0 要支持测试覆盖率只需将 Xdebug3Driver、Xdebug2Driver 的修改调整为修改

vendor/phpunit/php-code-coverage/src/Driver/Xdebug.php
