Mockity™ [discontinued project]

The Mockity Logo

Mockity™ is a C++ test helper class for Microsoft Visual Studio that helps us in inspecting classes and creating mocks. The project is discontinued on our end and we have moved to a Catch2-based testing. Mockity™ codes are available on Github.

Installation

You can obtain the files from the Mockity™ GitHub repo and place them in the appropriate projects of your solution as described in the Files section below.

Files

The .hpp extension indicates that there is no applicable .cpp file

Mockity™ consist of the following files, to be placed in the indicated sections of your solution:

Part of dev project mockity_project.hpp
#define directives that make development a bit more transparent.

Part of dev project mockity_project.hint
Hints for the Visual Studio IDE

Part of test project mockity_tests.hpp
The main Mockity™ file.

Part of test project mockity_tests.hint
Hints for the Visual Studio IDE

Componens and use

The name of each element starts with the word Mockity so that autosuggest can offer Mockity's various elements easily.

mockity_project.hpp

This file contains only two defines. MOCKITY_PROTECTED and MOCKITY_VIRTUAL can be used when the only reason to make something protected or virtual is for the Mockity derived classes to work properly. They simply expand to protected and virtual, respectively.

mockity_tests.hpp

  • (define) MOCKITY_MS_TEST_INCLUDE: Shorthand when icluding CppUnitTest.h
  • (define) MOCKITY_USE_MS_TEST_NAMESPACE: Shorthand for using the MS Test namespace
  • (define) MOCKITY_SRAND: Shorthand for a fixed "random" seed
  • (define) MOCKITY_FAIL_STUB: Stub for unimplemented tests. Fails the test with the message highlighting the need to implement it properly.
  • (define) MOCKITY_INIT_STRINGER: Calls Mockity::Stringer's constructor
  • (define) MOCKITY_WITH_STRINGER: Provides for public inheritance from Stringer
  • (namespace) Mockity: The Mockity™ namespace
  • (class) Mockity::Stringer: The Stringer inspection class. See below for more details.
The Mockity::Stringer class

Mockity::Stringer is Mockity's inspector helper class. It should be one of the parent classes of the mock/inspector classes you create. Stringer helps count function calls and track calling order. Currently, Mockity::Stringer is not thread-safe.

Interface description:

  • void expectOrder(std::string s): Call it from the test method when defining your expected call order. Pass the code/name of the next expected method call to record the order the methods are expected to be called.
  • void countFunctionCall(std::string s): Used in the virtual method before calling the actual method in the parent class. Just pass it the code/name of the current method call in order to count how many times it is called. countFunctionCall could have been defined protected but it is made public for added flexibility.
  • bool assertOrder() const: returns true if the actual calling order is in line with the expectations. You can then simply Assert::IsTrue(pMockObject->assertOrder()).
  • unsigned getFunctionCallCount(std::string s) const: returns the number of calls to a specific code/method. You can check this output as part of one of your assertions.

Mockity::Stringer is named, in the footsteps of Dr. Watson, after Mr. Stringer, Miss Marple's aide in the Miss Marple films of the 1960s featuring Margaret Rutherford as Miss Marple and her husband, Stringer Davis, as Mr. Stringer.
