phpunit自定义用法

wget  https://phar.phpunit.de/phpunit-7.0.phar
chmod  +x  phpunit-7.0.phar
mv  phpunit-7.0.phar  /usr/local/bin/phpunit
phpunit  --version

mkdir  src
mkdir  tests

<?php
/*
@desc：自动加载带命名空间的类的函数
@param dir 需要注册自动加载的文件夹
*/
function autoloader($dir){
spl_autoload_register(function($name) use ($dir){
    $name = str_replace(‘\\‘,DIRECTORY_SEPARATOR,$name);
    require $dir.DIRECTORY_SEPARATOR.$name.‘.php‘;
});
}
define(‘ROOT‘,__DIR__);
autoloader(ROOT);

b. 测试类：
vim src/Money.php

<?php
class Money
{
private $amount;
public function __construct($amount)
{
    $this->amount = $amount;
}
public function getAmount()
{
    return $this->amount;
}
public function negate()
{
    return new Money(-1*$this->amount);
}
}

c. 测试文件：
vim tests/MoneyTest.php

<?php
use PHPUnit\Framework\TestCase;
class MoneyTest extends TestCase
{
public function testCanBeNegated()
{
    $a = new Money(1);
    $b = $a->negate();
    $this->assertEquals(-1, $b->getAmount());
}
}

phpunit  --bootstrap  src/autoload.php  tests/MoneyTest.php

<phpunit bootstrap="src/autoload.php">
<testsuites>
    <testsuite name="money">
        <directory>tests</directory>
    </testsuite>
</testsuites>
</phpunit>

b. 执行命令：

phpunit tests/MoneyTest
