Unit testing is a software testing technique where individual units or components of an application are tested independently to ensure they function correctly. The goal is to verify that each unit performs its intended functionality correctly according to its specifications.
Catch2 is a C++ unit testing framework. One of its main features is that it does not require any dependencies to get started. It is a header-only framework, so we just need to download and include a single file to run our tests.
In this Answer, we'll design an increment function that increments an integer and then test it on different inputs using the Catch2 framework.
We only need to download the catch.hpp file from the official GitHub
Catch2 provides a straightforward syntax for defining basic unit tests using the TEST_CASE macro. The unit tests are written in a tests.cpp file, and the following commands are executed to run the tests.
g++ -std=c++11 tests.cpp -o test.exe./test.exe
The first command compiles the tests.cpp file into an executable file, and the second command runs the executable.
In the example below, we have defined an increment function and created a unit test in the basic_testing.cpp file. Click the “Run” button below to start the unit test:
