7.7 0.0 coverage VS LuckyFlowAutomated browser tests for web applications. Similar to Ruby's Capybara.
0.9 10.0 coverage VS hashrHashr is a tiny library makes test on JSON response easier, and can also be used as a models object.

Coverage tool for Crystal lang
Before you start, you must understand this is a proof of concept. I'm not happy with the current code implementation.
Lot of features and options will change in the future.
The code will probably be rebuilt almost from scratch
Note also than it hasn't yet been properly tested. Ironic, for a cover tool, isn't it? :-) anyway, if you're bold enough to give a try, read the getting started below !
Just add this line in your
development_dependencies: coverage: github: anykeyh/crystal-coverage
Wait for the binary to compile. The binary will be build in
crystal-coverage spec/myfile_spec1.cr spec/myfile_spec2.cr
Coverage file will be recreated after your software run on
There's probably dozen of bugs. Please fill issues and PR are welcome.
The library will evolve, so don't hesitate to
shards update and test with the
latest release before submitting an issue.
Due to some limitation, there's probably still a non-zero chance your code will not compile with the coverage instrumentations.
In this case, you can give a look to the generated output using the
crystal-coverage src/main.cr -p
When you fill issues, would be great to isolate the code which fail to load, so I can add it to my code library and fix the library.
The performances will slightly degrade using the coverage tool. Note the software is executed without release flag.
To test in
--release mode, you can do:
crystal-coverage src/main.cr -p | crystal eval --release
How does it works?
It uses ASTNode parsing to inject coverage instrumentations and reflag the lines
of code using
#<loc ...> directive
It covers only the relative files (e.g. require starting with
.) inside your
It then generate a report in the directory
/coverage/ relative to your project
