我正在尝试模拟Cache::put()门面。但这给了我一个错误。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,发生以下错误。

$ vendor/bin/phpunit

我尝试了很多方法,但无法解决。谢谢。

由于Laravel's facade可能会帮助他人,因此包含了一些辅助功能,该功能可以与Mockery测试双倍

这意味着,当您使用shouldReceive时,可以将其与任何Mockery expectation链接,例如,在这种情况下,如果您不关心某些参数,则可以使用:

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

以防万一,可以指出您可能不会想要模拟缓存,而是实际上使用了真正的缓存。

那是因为它是仅用于测试的缓存:

通过vendor / bin / phpunit运行测试时,Laravel [....]在测试时会自动配置会话并缓存到阵列驱动程序,这意味着在测试期间不会保留任何会话或缓存数据。

请注意,与OP的测试不同,您可能需要遵循Laravel关于您的测试类的指导来扩展其TestCase以获得行为,例如

use PHPUnit\Framework\TestCase;

class ExampleTest extends TestCase
