Running tests

The standard way to run tests, which is also the command that travis is using:

cabal configure --enable-tests && cabal build && cabal test

There is an script in the bnf source directory, runtests.sh which does it for you with some small differences:

• it uses cabal-dev instead of cabal
• it tries to set your CLASSPATH variable for you (It has only been tested on linux so far)

Skipping system tests

Since we don't expect all bnfc contributors to have installed a compiler for every backend, there is a mechanism, based on cabal flags, that allows you to skipped some of the system tests based on the target language. For instance, if you don't have a JDK nor the ocaml environment you can use the following command:

cabal configure --enable-tests -f-java-tests -f-c-tests && cabal build && cabal test

The possible flags are:

• haskell-tests
• java-tests
• c-tests
• cpp-tests
• latex-tests
