phpunit中的stubs桩件与上桩

发布时间：2021-09-21 23:32:13编辑：雪饮阅读（）

这里要上桩的类

Database.php：

<?php declare(strict_types=1);
final class Database
{
    public function doSomething()
    {
        // 随便做点什么。
    }
}

对被测类进行上桩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->method('doSomething')
            ->willReturn('foo');

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

此时运行是会报错的
