https://cestframework.com/

A test-driven development framework for C++ and C inspired by Jest and similar frameworks.

Cest requires a C++ compiler with C++14 support or greater. These should be available on most systems. It can be used either stand-alone or integrated with an external build system.

Download the latest cest release from GitHub: https://github.com/cegonse/cest/releases

Create a new test suite in the called, for example, test_sum.cpp:

#include <cest>

int sum(int a, int b) {
    return a + b;
}

describe("testing additions", []() {
    it("adds 1 + 2 to equal 3", []() {
        expect(sum(1, 2)).toBe(3);
    });
});

Build test suite including the Cest framework header, and run the binary. Cest will run your new test:

g++ -I. --std=c++14 test_sum.cpp -o test_sum
./test_sum

PASS  spec/test_sum.cpp:11 it adds 1 + 2 to equal 3

You have created your first test with Cest!

The Cest core is a single C++ header. To integrate it into your build system, simply add the cest header to your include path and include cest in your tests.

The framework header already includes a main() function, so tests must be linked without any additional entry point.

Cest runner will execute all tests inside the suite and return 0 on success and 1 on failure.

To see an integration example, check the cpm package manager.

Cest is MIT licensed.

Feel free to create any issues or pull requests with new functionality you deem useful! I will review issues created by others first.

Documentation is hosted in GitHub Pages in a different repository, found here: https://github.com/cegonse/cest-docs. Please create any issues related to the documentation in the main repository (cegonse/cest) instead of the docs one.

Building

Cest source code is in the src/ directory, separated in multiple header files. The final build is a single header library, which is built using Quom.

To generate the library amalgam, install Quom and build doing:

pip install quom
make build

This will generate the final library build in the build/ directory.

Roadmap

• Basic test support (it, xit, fit)
• macOS and Linux support
• Test parametrization support
• Basic expect matchers
• Nested test suite support
• Simple integration of custom expect matchers
• cest-runner for watch mode functionality of multiple suites
• Complex expect matchers (comprehensive STD collection support)
• Test cases run in an subprocess to avoid crashing the whole suite
• Integrated optional malloc / free overrides
• Windows support
