You can read up more on these at the extremely informative What I Wish I Knew When Learning Haskell./src directory. We're following the other convention, which is to place library code in a directory shocking titled... library./test. We have several kinds of tests:/test/testsuite/test/doctest; actual tests in each source file in /library/test/lint/test/coverage-code/test/coverage-docs/bench/app or /exe. Since our project contains multiple executables, we use the name of the executable itself (for example /fission-web).
