What's coverage?
It's meant to help you determine the amount of your code tested via unit testing. It's still undocumented. If you've got the source checked out, you can do:
$ make interpreter $ make coverageThis runs eutest with the interpreter only, and builds a database of coverage for the standard library. There's a post-processor, bin/eucoverage.ex that generates html reports on the coverage of the test suite. Here is an oldish example (the format may have changed a bit since then, and the data certainly has):
http://mattlewis.users.sourceforge.net/unit-test/
Here's the nearest thing to documentation, from the dev mail list:
-coverage [file|dir] This specifies what files to gather stats for. If you supply a directory, it recurses. Only files that are obviously euphoria are included (.e, .ew, .eu, .ex, .exw, .exu).
-coverage-db <file> This one allows you to specify a specific location and name for the database where coverage information is stored. It's an EDS database. By default, the DB is eui-cvg.edb.
-coverage-erase Tells the interpreter to start over. By default, multiple runs accumulate coverage in the DB.
Run bin/eucoverage.ex <coverage database> to generate the reports. It creates a subdirectory where the coverage database is located with the same name as the base of the database file name. In that directory, there will be an index page, a css file and a subdirectory. The index file is a summary of all of the files for which there are any stats. You can drill into each file to see the details of what was executed. "
Since then, those have been added to eutest, with the addition of the -coverage-pp parameter with eutest that tells eutest how to post process the coverage data. Also, there is:
-coverage-exclude <patern>
