deno test --coverage Strategy Documentation #1412
Description
I'd really like to see a couple of lines in the test --coverage documentation.
There's an issue that code coverage is given by many test runners as a simple percentage.
But the question we have to ask is "a percentage of what, exactly?"
- This could be simply the number of lines that have been covered.
- Or, we should expect, that whitespace and empty statements are ignored.
- Or, you can create a control-flow graph and provide a percentage of nodes of this graph that are covered.
- Etc, etc, etc.
It's always an option to look at the source code and determine the strategy used by deno test but it would be nice if there was a short statement in the documentation that informed the casual reader just so that we know what the percentage given is a percentage of.
