Laravel 5.1模拟``唯一''验证规则 [英] Laravel 5.1 mocking 'unique' validation rule

问题描述

我们在应用程序上使用唯一"规则进行验证，但是对于测试，我们通过使用存储库模式来模拟数据库层.有没有一种方法可以模拟unique规则，以便它不会尝试检查数据库?

We are using the 'unique' rule for validation on the application, but for tests we're mocking the database layer through the use of repository pattern. Is there a way to mock the unique rule so that it doesn't attempt to check the database?

我尝试了模拟Illuminate\Validation\Validator::validateUnique，它不起作用，但是由于该方法是受保护的.

I tried mocking Illuminate\Validation\Validator::validateUnique it doesn't work but since the method is protected.

推荐答案

唯一规则以及其他一些规则(例如 exists )使用状态验证器进行验证检查.默认情况下，使用 DatabasePresenceVerifier .它实现了由2种方法组成的 PresenceVerifierInterface .您可以模拟该验证程序的方法，并在测试期间使用它.您可以使用

unique rule, along with a few other rules (e.g. exists) uses presence verifier to do validation checks. By default DatabasePresenceVerifier is used. It implements PresenceVerifierInterface that consists of 2 methods. You could mock methods of that verifier and use it during tests. You can access the verifier with

\Validator::getPresenceVerifier()
\Validator::setPresenceVerifier()
