PHPUnit 代碼覆蓋率顯示 0% 覆蓋率

Question

對於我的庫（ source ）之一，我已將 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>

在上面的源代碼中，phpunit.xml.dist 被簡單地復制為 phpunit.xml。

我的代碼覆蓋率報告正在生成，但報告顯示代碼覆蓋率為 0%。 但是根據測試（檢查源代碼），我確定它必須超過 0%。

有人可以建議我的配置哪里出錯了嗎？

Answer 1

在每個測試的注釋中， @covers注釋告訴 PHPUnit 該測試中覆蓋了哪些代碼。

可以在測試代碼中使用 @covers 注釋來指定測試方法要測試的方法：

 /** * @covers BankAccount::getBalance */ public function testBalanceIsInitiallyZero() { $this->assertEquals(0, $this->ba->getBalance()); }

如果提供，則僅考慮指定方法的代碼覆蓋率信息。

此外，請確保您已安裝xdebug，因為它是代碼覆蓋率報告工作所必需的。

Answer 2

我有一個類似的問題。 就我而言，我確定正在測試該方法，因為覆蓋率報告顯示所有行均為綠色（意味着測試正在通過它們運行），但某些方法的摘要顯示為 0%，我的代碼中唯一奇怪的是像這樣縮進的深層嵌套數組：

$array['key']
    ['foo']
    ['bar']
    ['fooz']
    ['bazz'] = "some_value";

在使它成為一個像它一樣工作之后

$array['key']['foo']['bar']['fooz']['bazz'] = "some_value";

這是一個奇怪的問題，有一個奇怪的漫游

希望能幫助到你

Answer 3

您應該檢查 filter->whitelist 設置是否確實包含您要按代碼覆蓋率分析的源文件。

Answer 4

我想再添加一個可能的原因，說明一切都配置正確，但代碼覆蓋率僅為0% 。 當您將所有待測代碼調用放在 PHPUnit setUp()和setUpBeforeClass()方法中時，就會發生這種情況。 在實際測試方法中，您仍然可以檢查生成的輸出，但不會影響覆蓋率。

此外，如果您的有效 PHPUnit 測試方法不包含任何斷言（並且您被迫使用 PHPUnit 的@doesNotPerformAssertions注釋），則此類測試也不會生成覆蓋率。

換句話說，如果您關心代碼覆蓋率，請將事情移至帶有斷言的 PHPUnit 測試。

Answer 5

由於這是我找到的第一個答案，因此我將為那些最終遇到類似情況的人留下此評論。 我的情況是forceCoversAnnotation="true" 。 如果您將其從 phpunit.xml 中刪除，代碼覆蓋率將按預期工作。
