phpunit中stubs受method的影响

发布时间：2021-09-21 23:41:27编辑：雪饮阅读（）

 上文中我们实现了桩件与上桩，那么我在原始类中添加一个名叫method的方法

Database.php：
<?php declare(strict_types=1);
class Database
{
    public function doSomething()
    {
        // 随便做点什么。
    }
    public function method()
    {
        // 随便做点什么。
    }
}
此时就会发现上桩测试失败

什么意思呢？就是说stubs对于原始类中不允许存在有名为method的方法存在。
那么如果原始类中非要存在method方法，也可以用如下方式修改于测试类中
也就是说只是修改下配置桩件的地方即可。
DatabaseTest.php：

<?php declare(strict_types=1);
use PHPUnit\Framework\TestCase;

final class DatabaseTest extends TestCase
{
    public function testStub(): void
    {
        // 为 SomeClass 类创建桩件。
        $stub = $this->createStub(Database::class);

        // 配置桩件。
        $stub->expects($this->any())->method('doSomething')->willReturn('foo');

        // 现在调用 $stub->doSomething() 会返回 'foo'。
        $this->assertSame('foo', $stub->doSomething());

    }
}

那么再次运行就没有什么问题了
