单元测试

安装

composer require --dev phpunit/phpunit

配置

项目根目录新增配置文件 phpunit.xml phpunit.xml 配置项文档 可按照项目需求进行自定义配置

<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="vendor/phpunit/phpunit/phpunit.xsd"
    bootstrap="support/bootstrap.php"
    cacheDirectory=".phpunit.cache"
    executionOrder="depends,defects"
    shortenArraysForExportThreshold="10"
    requireCoverageMetadata="false"
    beStrictAboutCoverageMetadata="true"
    beStrictAboutOutputDuringTests="true"
    displayDetailsOnPhpunitDeprecations="true"
    failOnPhpunitDeprecation="true"
    failOnRisky="true"
    failOnWarning="true"
    colors="true">
    <testsuites>
        <testsuite name="tests">
            <directory>./tests</directory>
        </testsuite>
    </testsuites>
    <source>
        <include>
            <directory suffix=".php">./app</directory>
        </include>
    </source>
</phpunit>

使用

新建文件 tests/TestConfig.php,用于测试数据库配置

<?php
use PHPUnit\Framework\TestCase;

class TestConfig extends TestCase
{public function testAppConfig()
    {$config = config('app');
        self::assertIsArray($config);
        self::assertArrayHasKey('debug', $config);
        self::assertIsBool($config['debug']);
        self::assertArrayHasKey('default_timezone', $config);
        self::assertIsString($config['default_timezone']);
    }
}

运行

项目根目录里运行全部测试用例

./vendor/bin/phpunit

项目根目录里运行指定测试用例

./vendor/bin/phpunit tests/TestConfig.php

结果类似如下:
