Criterion is a cross-platform unit testing framework for C and C++ that automatically registers tests and provides a xUnit-style structure with minimal boilerplate. Tests run in isolated processes so crashes and signals can be reported and asserted, with support for parameterized tests, theories, and TAP output.

Use cases

• unit test c code without boilerplate
• test c++ code with a unified framework
• assert that code crashes or raises signals
• write parameterized tests and theories in c
• output test results in TAP format for CI
• run tests on linux, macos, and windows

When to choose

• you write C99 or C++11 code and want automatic test registration with no main function
• you need process-isolated tests that survive and report crashes
• you want one framework working identically for both C and C++ across platforms

When to avoid

• you need a header-only or single-file test framework
• your toolchain doesn't support the platforms Criterion targets
• you prefer a minimal assert-only library like MinUnit or Catch2-style single headers
