PHPUnit + Laravel单元测试常用技能(4)

5. 代码覆盖率

使用--coverage-html导出的报告含有类与特质覆盖率、行覆盖率、函数与方法覆盖率。可查看当前单元测试覆盖的范围。例如输出WebDefenderTest的代码覆盖率到桌面(phpunit tests/unit/WebDefenderTest --coverage-html ~/Desktop/test)

6. 指定代码覆盖率报告要包含哪些文件

在配置文件(phpunit.xml)里设置whitelist中的processUncoveredFilesFromWhitelist=true, 设置目录用<directory>标签,设置文件用<file>标签。例如指定app/Services目录下的所有文件和app/Facades/Services/WebDefenderService.php在报告中。

示例代码:

 <?xml version="1.0" encoding="UTF-8"?>
  <phpunit backupGlobals="false"
       backupStaticAttributes="false"
       bootstrap="tests/bootstrap.php"
       colors="true"
       convertErrorsToExceptions="true"
       convertNoticesToExceptions="true"
       convertWarningsToExceptions="true"
       processIsolation="false"
       stopOnFailure="false">
    <testsuites>
      <testsuite name="Unit">
        <directory suffix="Test.php">./tests/Unit</directory>
      </testsuite>

      <testsuite name="Feature">
        <directory suffix="Test.php">./tests/Feature</directory>
      </testsuite>
    </testsuites>
    <filter>
      <whitelist processUncoveredFilesFromWhitelist="true">
        <directory suffix=".php">./app/Services</directory>
        <file>./app/Facades/Services/WebDefenderService.php</file>
      </whitelist>
    </filter>
    <php>
      <server name="APP_ENV" value="local"/>
      <server name="BCRYPT_ROUNDS" value="4"/>
      <server name="CACHE_DRIVER" value="credis"/>
      <server name="MAIL_DRIVER" value="array"/>
      <server name="QUEUE_CONNECTION" value="sync"/>
      <server name="SESSION_DRIVER" value="array"/>
      <server name="APP_CONFIG_CACHE" value="bootstrap/cache/config.phpunit.php"/>
      <server name="APP_SERVICES_CACHE" value="bootstrap/cache/services.phpunit.php"/>
      <server name="APP_PACKAGES_CACHE" value="bootstrap/cache/packages.phpunit.php"/>
      <server name="APP_ROUTES_CACHE" value="bootstrap/cache/routes.phpunit.php"/>
      <server name="APP_EVENTS_CACHE" value="bootstrap/cache/events.phpunit.php"/>
    </php>
  </phpunit>
