如何使用Delphi Mocks驗證多個模擬期望？

Question

Delphi Mocks中mock.verify和mock.verifyAll有什麼區別？它是否驗證其他模擬的期望？ 我想驗證爲當前單元測試創​​建的所有模擬的所有期望。

Answer 1

你可以告訴模擬一個接口，它也可以模擬其他接口。如果您通過支持另一個界面來詢問您的模擬界面，這很有用。

Verify檢查直接模擬類型的期望值，而VerifyAll也檢查其他接口的期望值。

例

var 
    foo: TMock<IFoo>; 
begin 
    foo := TMock<IFoo>.Create; 
    foo.Implements<IBar>; 
    foo.Setup.Expect.Once.When.DoThis; 
    foo.Setup<IBar>.Expect.Once.When.DoThat; 

    // pass mock to tested component which 
    // calls DoThis and Supports(IBar) and calls DoThat 

    foo.Verify; // checks if DoThis was called once 
    foo.VerifyAll; // also checks if DoThat on the mock as IBar was called. 
end;
