无法在 Laravel 中模拟 Cache::put() 外观

Question

我正在尝试模拟 Cache::put() 外观。但它给了我一个错误。我尝试了不同的方法，但无法弄清楚。

public function testGetAllFromDatabase()
{
    $industry = new Industry();

    Cache::shouldReceive('has')
        ->once()
        ->with('industries.all')
        ->andReturn(false);

    Cache::shouldReceive('put')
        ->with('industries.all', '', 0)
        ->andReturn(true);

    $this->industryMock
        ->shouldReceive('all')
        ->once()
        ->andReturn(array_reverse($this->industries));

    $this->app->instance(Industry::class, $this->industryMock);

    $industryRepository = new IndustryRepository();
    $all = $industryRepository->all();
    dd($all);
    $this->assertContains( $this->industries[2], $all);
}

但是当我执行它时出现了以下错误。

$ vendor/bin/phpunit

...E                                                                4 / 4 (100%)

There was 1 error:

我尝试了很多方法，但无法修复。谢谢。

Answer 1

既然对别人有帮助，Laravel's facade includes helper functions that allow swapping then with a Mockery测试双人

这意味着当您使用 shouldReceive 时，您可以将它与任何 Mockery expectation 链接起来，例如在这种情况下，如果您不关心某些参数，您可以使用：

Cache::shouldReceive('put')
    ->with('industries.all', \Mockery::any(), \Mockery::any())
    ->andReturn(true);

Answer 2

如果对其他人有帮助，最好指出 您可能不想模拟 Cache，而是实际使用真正的缓存。

那是因为它是一个仅供测试的缓存:

When running tests via vendor/bin/phpunit, Laravel [....] automatically configures the session and cache to the array driver while testing, meaning no session or cache data will be persisted while testing.
https://laravel.com/docs/8.x/testing#environment

请注意，与 OP 的测试不同，您可能需要遵循 Laravel 关于您的测试的指导 class 扩展他们的 TestCase 以获得行为，例如

use PHPUnit\Framework\TestCase;

class ExampleTest extends TestCase
