I have a class Foo that uses class Bar. Bar is used only in Foo and Foo is managing Bar, therefore I use unique_ptr (not a reference, because I don't need Bar outside of Foo): using namespace std;...

I'm currently learning unit testing with google mock What is the usual use of virtual void SetUp() and virtual void TearDown() in the google mock? An example scenario with codes would be good.

I'm trying to do some sleep inside .WillOnce before invoking FuncHelper. So I need something similar to the following: EXPECT_CALL(*_mock, Func(_,_,_)).Times(1) .WillOnce(DoAll(InvokeWithoutArgs(...

What will be the best way to write (google) test cases using a google mock object and expect the EXPECT_CALL() definitions being called from another thread controlled by the class in test? Simply c...

Not so much a question as a piece of knowledge sharing. According to the GoogleMock FAQ it is not possible to mock variadic functions since it is unknown how many arguments will be given to the fun...

How can I match value of an element in a union for an input argument e.g - if I mock a method with the following signatiure - struct SomeStruct { int data1; int data2; }; void SomeMethod...

Google suggests delegating calls to a parent object when you need to invoke functionality of the real object, however this does not really create a partial (hybrid) mock. When invoking the real obj...

The Google Mock documentation says: Important note: Google Mock requires expectations to be set before the mock functions are called, otherwise the behavior is undefined. In particular, you must...

I have a class with several methods that depend on each other. Lets say foo(), bar() and baz(). When I test bar() I need to mock the behavior of foo(), when I test baz() I need to mock the behavio...

If I call EXPECT_CALL twice on the same mock object in the same TEST_F . . . what happens? Are the expectations appended to the mock object or does the second call erase the effects of the first c...

I need to detect that a given function has been called exactly ONCE with a certain set of arguments. EXPECT_CALL(Mock_Obj, func("abc")).Times(1) but it's ok for that function to be called with di...

It's tremendously helpful that there's a tool to generate mock versions of the client stubs. Testing the server side is causing me tons of headache at the moment. Enough headache where I feel like ...

So I am trying to learn how to write unit Tests and i stumbled upon the problem, that I don't understand how to create mock objects. Here's my example: I have this class: class FooChild { public: ...

This is going to be a self-answered, FAQ-style question. See answer below. With Visual Studio 2017/2019 it is really easy to set up a new Google Test project and start writing tests (as long as you...

I need to mock the following function: virtual void fun() noexcept = 0; Is it possible using gmock ? Gmock has the following macro:#define GMOCK_METHOD0_(tn, constness, ct, Method, ...) but t...

Is there a macro in Google Mock to ensure compile time check of the signature of f() by appending the override keyword to the macro substitution: struct I { virtual void f() = 0; }; struct MockI...

I really like catch.hpp for testing (https://github.com/philsquared/Catch). I like its BDD style and its REQUIRE statements, its version of asserts. However, catch does not come with a mocking fram...

I have not even begun testing and I am encountering some syntax issues with GMock's MOCK_METHOD macro even though I am following GMock's documentation properly. Could it be a compiler issue? I have...

I'm mostly using ordered expectations with GoogleMock, so all EXPECT_CALLs were written inside the scope of a testing::InSequence object. Now I want to relax the ordering so I split the expectatio...

I have a factory that returns a smart pointer. Regardless of what smart pointer I use, I can't get Google Mock to mock the factory method. The mock object is the implementation of a pure abstract ...

My actual code (class name changed, some cut, as it is company confidential, but there is only one compiler error, so what I cut should not be affecting things) class Xyz { public: virtual void v...

The constructor of my class is A( ... std::function<bool(const std::string&, const std::string&)> aCallBack, ... ); I want to use EXPECT_CALL to test it. This callback is from a...

In all the documentation about gmock I always find the mock object to be instantiated inside a test, like that: TEST(Bim, Bam) { MyMockClass myMockObj; EXPECT_CALL(MyMockObj, foo(_)); ... } S...

I installed the Microsoft.googletest.v140.windesktop.msvcstl.static.rt-dyn package into my VS 2017 application solution. This was accomplished by adding a new GoogleTest project to my solution via ...

I am trying to use GMock (google mocking framework for c++) for the first time. I have the following class: class LocalCache { public: virtual time_t GetCurrentTime() = 0; virtual int AddEntry(c...
