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。
