In this chapter, we will discuss how to add the Google Test, Boost.Test, Catch2, and Doctest framework to a project in CLion and how to write a simple set of tests.Īs an example, we will use the DateConverter project that you can clone from github repo.

Setting up a testing framework for your project

Gutter icons to run or debug tests/suites/fixtures and check their status,Īnd code generation for tests and fixture classes (available for Google Tests).įor CMake projects, CLion also supports CTest. This is useful when you need to further pass the results to a continuous integration system such as TeamCity or Jenkins.ĬLion's integration with Google Test, Boost.Test, Catch2, and Doctest includesįull code insight for framework libraries, Most of the testing frameworks provide exporting results in XML format. Also, modern frameworks automatically register new tests, so you don't need to do that manually.įrameworks take care of the tests output: they can show verbose descriptive outputs, as well as user-defined messages or only briefed pass/fail results (the latter is especially handy for regression testing). With frameworks, it's easy to create and run subsets of tests grouped by common functionality (suites) or shared data (fixtures). Also, they can include tolerances for floating point comparisons and even pre-implemented exception handlers that check raising of an exception under certain conditions. Checkers provided by testing frameworks often have configurable severity (warning, regular expectation, or a requirement). With a framework, you can specify whether or not a failure of a single check should cancel the whole test execution: along with the regular ASSERT, frameworks provide EXPECT/CHECK macros that don't interrupt your test program on failure.Ĭheckers are macros for comparing the expected and the actual result. Unit testing frameworks not only help automate these operations, but also let you benefit from the following:

Manual unit testing involves a lot of routines: writing stub test code, implementing main(), printing output messages, and so on. Mock objects are lightweight implementations of test targets, used when the under-test functionality contains complex dependencies and it is difficult to construct a viable test case using real-world objects.

Unit testing is often combined with mocking. They are used to set up and clean up the environment for each test within a group and thus avoid code duplication. Fixture classes help organize shared resources for multiple tests. Suites combine tests with common functionality (for example, when performing different cases for the same function). It's useful to group test cases when they are logically connected or use the same data.

Organizing tests in a way that the order in which you run them doesn't affect the results. 3 - checking the results (assertions block)Ĭreating tests for all publicly exposed functions, including class constructors and operators.Ĭovering all code paths and checking both trivial and edge cases, including those with incorrect input data (refer to negative testing).Īssuring that each test works independently and does't prevent other tests from execution.
