istanbul coverage about tape-run HOT 7 CLOSED

it might not be easy to do with istanbul, but it is using coverify:

$ browserify -t coverify script.js | tape-run | coverify
TAP version 13
# one
ok 1 true

1..1
# tests 1
# pass  1

# ok

# coverage: 10/10 (100.00 %)

For anyone using Istanbul I made tape-istanbul. The example references tape-run but it'll work for anything where you pipe in code and get back console logs as stdout. substack's method in coverify for wrapping code in coverage functions and then extracting coverage data streamingly is a lot more clever. The only reason I made an Istanbul utility is that coverify's deps are a bit out of date and it has some trouble with ES6 transpilation / source maps. Istanbul handles that better at the moment.

fyi the above would work with node as well:

$ browserify -t coverify script.js | node | coverify

good to know about tape-istanbul though!

When I run rollup -c ./rollup.test.config.js | tape-run | coverify the output of coverify is always empty even though tape-run prints test results. Did something general change? I noticed that tape-istanbul also doesn't output anything.

Did you include the coverify plugin in your rollup setup?

Oh nevermind, I guess it's not actually possible to use coverify in combination with rollup. My bad! :)
