Welcome to the D community and thanks for your interest in contributing! If you need help you can ask questions on #d IRC channel on freenode.org (web interface) or on our forum.

This section explains commonly commands which are commonly used to test the low level runtime library for the D programming language.


Run all tests

make -f posix.mak unittest -j4

Run an individual test

Sometimes it can be helpful to rerun only a single test which tests the module or feature one is working on. For example:

make -f posix.mak test/coverage/.run

Run benchmark

If you are making a bigger change or want to improve the performance of a specific function in druntime, you should run the included benchmark script:

rdmd benchmark/runbench.d
