对于我的某个库（source），我已将PHPunit配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<phpunit bootstrap="vendor/autoload.php" colors="true">
<testsuites>
<testsuite name="PHPReboot Stopwatch Test Suite">
<directory>tests/Phpreboot/Stopwatch</directory>
</testsuite>
</testsuites>
<filter>
<whitelist>
<directory suffix=".php">src/Phpreboot/Stopwatch</directory>
</whitelist>
</filter>
<logging>
<log type="coverage-html" target="./log/codeCoverage" charset="UTF-8"
yui="true" highlight="true"
lowUpperBound="50" highLowerBound="80"/>
<log type="testdox-html" target="./log/testdox.html" />
</logging>
</phpunit>
在上面的source中，phpunit.xml.dist只是复制为phpunit.xml。
我的代码覆盖率报告正在生成，但报告显示0％的代码覆盖率。但是根据测试（检查源代码中的代码），我确定它必须大于0％。
有人可以建议我的配置出错吗？

答案 0 :(得分：3)
在xdebug的每个测试的注释中告诉PHPUnit该测试中涉及的代码是什么。
可以在测试代码中使用@covers注释来指定哪个 测试方法想要测试的方法：
/** * @covers BankAccount::getBalance */ public function testBalanceIsInitiallyZero() { $this->assertEquals(0, $this->ba->getBalance()); }如果提供，则仅指定的代码覆盖率信息 方法将被考虑。
此外，请确保您已安装{{3}}，因为代码覆盖率报告可以使用。
答案 1 :(得分：2)
我有类似的问题。在我的情况下，我确信该方法正在测试，因为覆盖率报告显示所有行都是绿色的（意味着测试正在通过它们）但是某些方法的摘要显示为0％，我的代码中唯一奇怪的是深嵌套数组缩进，如下所示：
$array['key']
['foo']
['bar']
['fooz']
['bazz'] = "some_value";
制作单曲之后
$array['key']['foo']['bar']['fooz']['bazz'] = "some_value";
奇怪的是，这是一个奇怪的问题
希望有所帮助
答案 2 :(得分：1)
您应该检查filter-＆gt;白名单设置是否包含您要通过代码覆盖率分析的源文件。
答案 3 :(得分：1)
由于这是我找到的第一个答案，因此对于那些遇到类似情况的人，我将保留此评论。我的情况是forceCoversAnnotation="true"。如果将其从phpunit.xml中删除，代码覆盖范围将按预期工作。
答案 4 :(得分：0)
我想添加所有可能正确配置所有其他原因的可能原因，但是代码覆盖率仅为 0％。当您将所有待测代码调用放入PHPUnit setUp()和setUpBeforeClass()方法中时，就会发生这种情况。在实际的测试方法中，您仍然可以检查生成的输出，但这不会影响覆盖范围。
此外，如果有效的PHPUnit测试方法不包含任何断言（并且PHPUnit强制您使用@doesNotPerformAssertions注释），则也不会为此类测试生成覆盖率。
换句话说，如果您关心代码覆盖率，请使用断言将内容移至PHPUnit测试。
