如何模拟唯一验证规则? [英] How can I mock unique validation rule?

问题描述

我正在为ResourceController的store()函数编写测试用例，该功能在数据库中添加了新资源.

I am writing test cases for a store() function of a ResourceController which adds a new resource in database.

在我的测试案例中，我不允许访问数据库，因此我在嘲笑所有数据库交互&现在，我需要模拟unique验证规则.

I am not allowed to access database in my test cases, So I am mocking all the database interactions & now I need to mock the unique validation rule.

我已经Google搜索了&甚至在stackoverflow上搜索，但我没有 找到任何具体的东西.

I have Googled it & even searched on the stackoverflow but I didn't found anything specific.

这是我所知道的:- 我可以模拟\Validator::getPresenceVerifier() & \Validator::setPresenceVerifier()，但是如果我模拟它们，那么我将无法制作验证器对象. 此处的StackOverflow问题

Here is what I know:- I can mock the \Validator::getPresenceVerifier() & \Validator::setPresenceVerifier() but if I mock them, then i will not be able to make the validator object. StackOverflow Question Here

谁能引导我正确的方向.

Can anyone guide me in the right direction.

推荐答案

好，给您一些想法:首先，Validator是一个Facade，这意味着您可以使用Validator :: shouldReceive模拟它的任何方法.您也可以使用Validator::swap($mock)模拟整个根对象.如果您的控制器使用的是$this->validate，则还可以通过替换内部验证器实例来模拟验证器-我怀疑您甚至可以在创建控制器时使用IoC容器注入它.

Ok, here are some ideas for you: First, the Validator is a facade, which means you can mock any method of it with Validator::shouldReceive. You can also mock the whole root object with Validator::swap($mock). If your controller is using $this->validate, you can also mock the validator by replacing the internal validator instance - I suspect you might even be able to use the IoC container to inject it when you create the controller.

如果所有其他方法都失败了，您还可以通过创建控制器的模型，然后在控制器模型上调用该方法来测试该方法-这样，您就可以模拟其他内部方法(例如，验证).您可以直接测试该方法，也可以再次使用App::bind映射您的模拟，以便其从调用方法中触发.

If all else fails, you can also test the method by creating a mock of the controller, and then calling the method on your controller mock - that way you can mock other internal methods (e.g. the validation). You can test the method directly, or use App::bind again to map your mock so that it triggers from the call method.

如果您正在使用自定义Request类进行验证，则还可以尝试模拟该类以完全禁用验证，或者使用自定义验证功能(而不是唯一的测试)将其替换为您自己的验证器.

If you are validating with a custom Request class, you can also try mocking that one to disable the validation entirely, or replace it with your own validator using a custom validation function instead of the unique test.
