根因分析

PHPUnit 的模拟构建器试图配置模拟类上不存在的方法，通常是由于方法名拼写错误或该方法为私有/最终/静态方法。

English

PHPUnit's mock builder is trying to configure a method that does not exist on the mocked class, usually due to a typo in the method name or the method being private/final/static.

解决方案

  1. Verify the method name spelling and visibility. Run `php -r "echo (new ReflectionMethod('App\\Service\\UserService', 'getUser'))->isPublic() ? 'public' : 'not public';"` to check if the method exists and is public.
  2. If the method is static or final, use `onlyMethods()` with the method name, or refactor the class to make the method non-final. Example: `$mock = $this->getMockBuilder(UserService::class)->onlyMethods(['getUser'])->getMock();`

无效尝试

常见但无效的做法:

  1. Adding a @runInSeparateProcess annotation to the test method to isolate state 90% 失败

    This does not fix the method name mismatch; it just runs the test in a separate process, which may mask the error but the underlying issue persists.

  2. Using createMock() instead of getMockBuilder() assuming it's a builder issue 85% 失败

    createMock() also uses the same method existence check internally; the error will still occur if the method does not exist.
