How do you write a unit test case in CPP?

Basic test workflow

1. Create references to other projects in the solution. To enable access to the functions in the project under test, add a reference to the project in your test project.
2. Link to object or library files.
3. Add #include directives for header files.
4. Write test methods.
5. Run the tests.

How do I google mock?

Using Google Mock involves three basic steps:

1. Use some simple macros to describe the interface you want to mock, and they will expand to the implementation of your mock class;
2. Create some mock objects and specify its expectations and behavior using an intuitive syntax;
3. Exercise code that uses the mock objects.

How is unit testing done in C++?

Unit testing with C++ requires a test runner. We write tests as functions, and then we link the functions into a binary that the build executes as a test target. So, we need a main function that knows how to run the tests, check the results, and print a report.

Why is Gmock used?

Gtest is a framework for unit testing. Gmock is a framework imitating the rest of your system during unit tests. Suppose you’re writing a piece of code that needs to interact with an unpredictable, expensive, external system (e.g. a Web site, a large database, a physical sensor, etc.)

What is a mock class?

Mocking is done when you invoke methods of a class that has external communication like database calls or rest calls. Through mocking you can explicitly define the return value of methods without actually executing the steps of the method.
