【 callable-fake】虚构你的可调用函数以加速测试

  Callable fake 是 Tim Macdonald 的一个 PHP 测试实用程序,它 “允许您伪造、捕获和断言对可调用 / 闭包的调用”。在某些情况下,此包可以帮助在测试中允许开发人员传递一个 callable。
  它有一个受 Laravel 虚构启发的 API,如下所示:
  // Before, you might collect callables to assert later……
  public function testEachLoopsOverAllDependencies(): void
  {
  // arrange
  $received = [];
  $expected = factory(Dependency::class)->times(2)->create();
  $repo = $this->app[DependencyRepository::class];
  // acthttps:www.weixiu3721.com
  $repo->each(function (Dependency $dependency) use (&$received): void {
  $received[] = $dependency;
  });
  // assert
  $this->assertCount(2, $received);
  $this->assertTrue($expected[0]->is($received[0]));
  $this->assertTrue($expected[1]->is($received[1]));
  }
  使用此软件包,您可以使用类似以下内容的内容:
  public function testEachLoopsOverAllDependencies(): void
  {
  // arrange
  $callable = new CallableFake();
  $expected = factory(Dependency::class)->times(2)->create();
  $repo = $this->app[DependencyRepository::class];
  // act
  $repo->each($callable);
  // assert
  $callable->assertTimesInvoked(2);
  $callable->assertCalled(function (Depedency $dependency) use ($expected): bool {
  return $dependency->is($expected[0]);https://www.weixiu3721.com
  });
  $callable->assertCalled(function (Dependency $dependency) use ($expected): bool {
  return $dependency->is($expected[1]);
  });
  }
  该包提供了诸如 assertCalled、assertNotCalled、assertInvoked 等断言。有关详细信息和示例,请务必查看项目自述文件中的可用 assertions 的完整列表。
  你可以在 GitHub 上了解更多关于此软件包的信息,获取完整的安装说明,并在 timacdonald/callable-fake 上查看源代码。
