Google Mock Unit Tests

Google Mock is a C++ mocking framework that can help you create a fake object of a class or an interface.

#What is Google Mock?

Google Mock is a C++ testing framework that allows developers to create mock objects for use in unit testing. These mock objects can simulate the behavior of real objects and can be used to test the interactions between objects in a system.

#Google Mock Key Features

Most recognizable Google Mock features include:

  • Mock objects: Google Mock allows developers to create mock objects that can simulate the behavior of real objects in the system.
  • Expectations: Google Mock provides a way to set expectations on the behavior of the mock objects, ensuring that the objects are behaving as expected.
  • Parameterized tests: Google Mock supports parameterized tests, allowing developers to run the same test with different input values.
  • Strict and nice mocks: Google Mock supports two types of mocks: strict and nice. Strict mocks enforce expectations on every call to the mock object, while nice mocks only enforce expectations on the calls that are explicitly specified by the developer.
  • Matchers: Google Mock provides a set of matchers that can be used to match arguments passed to the mock objects, making it easy to set expectations on specific values.
  • Custom actions: Google Mock allows developers to define custom actions that can be taken when a mock object is called, allowing for more complex testing scenarios.

#Google Mock Use-Cases

Some of the Google Mock use-cases are:

  • Unit testing: Google Mock can be used to create mock objects for unit testing, allowing developers to test the behavior of individual components in a system.
  • Integration testing: Google Mock can also be used for integration testing, allowing developers to test the interactions between components in a system.
  • Legacy code testing: Google Mock can be used to test legacy code that is difficult to test using traditional testing techniques.

#Google Mock Summary

Google Mock is a C++ testing framework that provides mock objects, expectations, parameterized tests, strict and nice mocks, matchers, and custom actions. It can be used for unit testing, integration testing, and legacy code testing.
