Criterion - 一个简单可扩展的 C 语言测试框架

A dead-simple, yet extensible, C test framework.

Philosophy

Most test frameworks for C require a lot of boilerplate code to set up tests and test suites -- you need to create a main, then register new test suites, then register the tests within these suits, and finally call the right functions.

This gives the user great control, at the unfortunate cost of simplicity.

Criterion follows the KISS principle, while keeping the control the user would have with other frameworks:

• Tests are automatically registered when declared.
• A default entry point is provided, no need to declare a main unless you want to do special handling.
• Test are isolated in their own process, crashes and signals can be reported and tested.
• Progress and statistics can be followed in real time with report hooks.

Installation

$ git clone 
$ cd Criterion
$ ./autogen.sh && ./configure && make && sudo make install

Given a test file named test.c, compile it with -lcriterion :

$ gcc -o test test.c -lcriterion

Samples

Sample tests can be found in thesample directory.

Q. What's wrong with other test frameworks?

A. I worked with CUnit and Check, and I must say that they do their job very well -- the only thing that bugs me is that setting up a test suite from scratch is a pain, it should really be simpler. Most (if not all) high-level languages have test frameworks with automatic test registration, but all the ones for C require you to set up a main, manually register suites, then tests. Criterion tries to fix these shortcomings.

Q. Where has this been tested?

A. Currently, on Linux 2.6.32 and Linux 3.15.7, although it should work on most *nix systems. More tests will be added on the build matrix.

Q. Will this work under Windows/MSVC?

A. Windows support with MinGW is coming, but MSVC is a bit of a lost cause for the C language. The project internally uses c99 features and  extensions, and MSVC is stuck at supporting c89.
