The hpc-coveralls package

[Tags:bsd3, library, program]

This utility converts and sends Haskell projects hpc code coverage to coverall.io.

Usage

Commands to add to your project .travis.yml when using Travis CI:

 before_install:
   - cabal install hpc-coveralls
 script:
   - cabal configure --enable-tests --enable-library-coverage && cabal build && cabal test
 after_script:
   - hpc-coveralls [options] [test-suite-names]

hpc-coveralls converts and sends Haskell projects hpc code coverage to coverall.io.

At the moment, only Travis CI has been tested, but hpc-coveralls should be compatible with other CI services (Check HpcCoverallsMain source for the list).

hpc-coveralls is still under development and any contributions are welcome!

Usage

Travis CI

Commands to add to your project .travis.yml when using GHC 7.8:

before_install:
  - cabal install hpc-coveralls
script:
  - cabal configure --enable-tests --enable-library-coverage && cabal build && cabal test
after_script:
  - hpc-coveralls [options] [test-suite-names]

When using a GHC version prior to 7.8, you have to replace the cabal test command by run-cabal-test, as in the following example:

before_install:
  - cabal install hpc-coveralls
script:
  - cabal configure --enable-tests --enable-library-coverage && cabal build
  - run-cabal-test [options] [cabal-test-options]
after_script:
  - hpc-coveralls [options] [test-suite-names]

The reason for this is explained in the next section.

For a real world example usage, please refer to this-project .travis.yml file (result on coveralls). You can also refer to the .travis.yml file of hpc-coveralls itself, which is configured with multi-ghc-travis.

The run-cabal-test command

When using hpc 0.6, cabal test outputs an error message and exits with the error code 1, which results in a build failure.

In order to prevent this from happening, hpc-coveralls provides the run-cabal-test command which runs cabal test and returns with 0 if the regex ^Test suite .*: FAIL$ never matches any line of the output.

As this issue is fixed in the hpc version shipped with GHC 7.8, you don't have to use run-cabal-test when testing with GHC 7.8 and can safely use cabal test.

Options

The --cabal-name option can be used to specify a custom executable name instead of the default cabal when calling cabal test.<br/> Below is an example which can be useful for projects with a Travis configuration based on multi-ghc-travis:

run-cabal-test --cabal-name=cabal-1.18

The hpc-coveralls command

This command parses the hpc generated output, converts its to Coveralls json format and finally sends it to coveralls.io over http.<br/> Multiple test suites can be specified, in which case the coverage report will be made of the merged coverage data generated by the specified test suites.<br/> For example, if your test suite are named test1 and test2, use the command as follows:

hpc-coveralls test1 test2

Options

The --exclude-dir option can be used to exclude source files located under a given directory from the coverage report.<br/> You can exclude source files located under the test/ by using this option as in the following example:

hpc-coveralls --exclude-dir=test [test-suite-names]

You can specify multiple excluded folders by using the following example syntax:

hpc-coveralls --exclude-dir=test1 --exclude-dir=test2 [test-suite-names]

Limitations

As Coveralls doesn't support yet partial-line coverage, the following convention is used to represent line coverage with line hit counts:

  • 0 : the line is never hit,
  • 1 : the line is partially covered,
  • 2 : the line is fully covered.

This convention is the same as the one used by cloverage coveralls output for Clojure projects code coverage.

There's an open issue to improve this.
