This is a simple test framework for diagrams. To test diagrams, first configure
% cabal configure -fcairo
Supported backends are: cairo, svg, postscript. canvas (HTML5) used to be supported and hopefully will be again soon. You can also do
% cabal configure -fall
to make an executable called "all-test" which will test all backends side-by-side. Then build:
% cabal build
This generates a file called cairo-index.html (or svg-index.html, etc). Open this in your browser.
% open cairo-index.html
Edit src/Diagrams/Tests.hs, and add to the examples list. Feel free to use helper functions inside the Tests.hs file. The name of the test should be a (UNIX) filename (no spaces, no slashes, no stars, etc)
To add a new backend, see the templates in cabal, src/Diagrams/Test/, and tests/*hs.
- Add a new -f option and Executable -test in diagrams-tests.cabal
- Add a src/Diagrams/Test/.hs
- Add a .hs in tests/ which just calls out to the above.
- Add to tests/All.hs
Now you can use
% cabal configure -f
