phpunit如何生成代码覆盖率？“No filter is configured, code coverage will not be processed”问题

发布时间：2021-10-21 22:07:12编辑：雪饮阅读（）

php的代码覆盖率生成有点麻烦。

大多数新手按照网上的一贯教程都会出现有驱动问题，当然这个一般就是按照官网的文档安装相关扩展即可。

那么还有一类错误官网没有直接明说，就是下面这个错误：

No filter is configured, code coverage will not be processed

那么这里从头到尾谈谈这个代码覆盖率如何生成。

首先运行命令如：

D:\phpstudy_pro\Extensions\php\php7.3.4nts\php.exe -r "phpinfo();" | findstr "bug" >>1.txt & D:\phpstudy_pro\Extensions\php\php7.3.4nts\php.exe -m >>1.txt & type 1.txt

输出结果很多，需要注意xdebug必须是2.7.0或以上

对于扩展类一般至少要有下面这几个

上面这些扩展都有了接下来如果去尝试代码覆盖率生成就基本不会报错与驱动有关的了，而是：

No filter is configured, code coverage will not be processed

此时通过配置生成向导命令：

D:\phpstudy_pro\Extensions\php\php7.3.4nts\php.exe D:\phpstudy_pro\WWW\phpunitLearning\phpunit-9.5.10.phar --generate-configuration

生成一个phpunit.xml的一个配置文件，默认会生成在当前cmd中你的当前目录中。

然后拷贝这个配置文件到你想要的地方中，然后根据自己的情况修改下里面的比如默认的引导bootstrap之类的。

这里以我这个修改好的phpunit.xml为例：

<?xml version="1.0" encoding="UTF-8"?>

<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/9.5/phpunit.xsd"

bootstrap="src/autoload.php"

cacheResultFile=".phpunit.cache/test-results"

executionOrder="depends,defects"

forceCoversAnnotation="true"

beStrictAboutCoversAnnotation="true"

beStrictAboutOutputDuringTests="true"

beStrictAboutTodoAnnotatedTests="true"

convertDeprecationsToExceptions="true"

failOnRisky="true"

failOnWarning="true"

verbose="true">

<directory>tests</directory>

</testsuite>

</testsuites>

<coverage cacheDirectory=".phpunit.cache/code-coverage"

processUncoveredFiles="true">

</include>

</coverage>

</phpunit>

src目录中的autoload.php：

<?php

function autoload($class){

include $class.'.php';

}

spl_autoload_register('autoload');

以及src下面一个空（内容为空）的default.php。

然后tests目录中的JavaTest.php：

<?php declare(strict_types=1);

use PHPUnit\Framework\TestCase;

final class JavaTest extends TestCase

{

public function testOne(): void

{

echo "\r\n".__METHOD__."\r\n";

$this->assertTrue(true);

}

public function testTwo(): void

{

echo "\r\n".__METHOD__."\r\n";

$this->assertTrue(true);

}

public function testThree(): void

{

echo "\r\n".__METHOD__."\r\n";

$this->assertTrue(true);

}

以及test目录中的MyTest.php：

<?php declare(strict_types=1);

use PHPUnit\Framework\TestCase;

final class MyTest extends TestCase

{

public function testOne(): void

{

echo "\r\n".__METHOD__."\r\n";

$this->assertTrue(true);

}

public function testTwo(): void

{

echo "\r\n".__METHOD__."\r\n";

$this->assertTrue(true);

}

public function testThree(): void

{

echo "\r\n".__METHOD__."\r\n";

$this->assertTrue(true);

}

那么接下来就可以运行代码覆盖率生成了：

C:\Users\Administrator>D:\phpstudy_pro\Extensions\php\php7.3.4nts\php.exe D:\phpstudy_pro\WWW\phpunitLearning\phpunit-9.5.10.phar -c D:\phpstudy_pro\WWW\phpunitLearning\phpunit.xml --coverage-html=D:\phpstudy_pro\WWW\phpunitLearning\report\
