crbehave is a behavior driven development framework for C that uses standard regular expressions for matching, instead of a specialized system, and instead of relying on macros.

The crbehave reads a specification of scenarios following the Gherkin given-when-then syntax and calls the respective functions for making the specification executable.

The scenarios are tested in separate worker processes for making sure complete feature specifications are executed without unnecessary delays, even if there are crashes or slow test code. The output should be piped through a sort for making sure the reports are diff-able.

It was originally written by the author after opening the first pages of Jamis Buck's excellent book, the "The Ray Tracer Challenge - A Test-Driven Guide to Your First 3D Renderer", after finding, at that time, there was no adequate behavior driven development framework for C that would satisfy the author's taste.

None as long as you're on a conventional Unix-like OS base system with C compiler and standard headers installed.

Build and install:

./configure ~
make install

Build and run tests:

cd examples
./configure --enable-tests ~
make check

Run example tests from command line:

cd examples/tests
for a in tuples matrix bank canvas ; do
	./${a} <${a}.feature | sort -n | tee ${a}.report
done

The test programs accept the following command line options:

• -v Verbose output
• -j Specify the maximum number of worker processes

The test specification is read from stdin and the report is pushed to stdout.
