How can ibrik be used with mocha?

[thom-nic]

We have a suite of Mocha tests and I'm looking for a coverage tool to determine how thorough our tests are. Any idea how Mocha can integrate with ibrik? Thanks.

👍 same question here

Same problem here, trying to add coffeescript coverage to RTD using Mocha

[dashed]

Would like to know about this as well...

[jescalan]

+1, would be really excellent. I tried running ibrik cover _mocha and it did run the tests, but exited at the end without collecting any coverage information.

Would love to get a quick response here @Constellation

👍 I'm also looking for an answer to this.

+1 ... tried (modifying instructions for use of mocha w/ istanbul):

ibrik cover /usr/local/bin/_mocha -- --bail -u bdd --compilers coffee:coffee-script,litcoffee:coffee-script/register

... and I get:

No coverage information was collected, exit without writing coverage information.

[volkhin]

Any update on this?

The test run but no coverage collected.
ibrik cover ./node_modules/mocha/bin/_mocha -- --compilers coffee:coffee-script/register --reporter spec --recursive test/

This would be extremely useful.

A little off topic, but I wrote this gulp plugin using the coffee instrumentor from this project to allow for coffee code coverage under mocha:

gulp-coffee-istanbul.

Doesn't solve this issue but at least gives a workaround.

[rimunroe]

Unfortunately, gulp-coffee-istanbul only works with code which is written for the CoffeeScriptRedux compiler, and not actual CoffeeScript. Sadly, CoffeeScriptRedux is largely abandoned and is lagging far behind CoffeeScript in feature support.

[Constellation]

I'll investigate it at weekend.

[duereg]

@rimunroe I just fixed this. gulp-coffee-istanbul now uses the coffee-script compiler, not redux.

[justin-lau]

I'm using @duereg's fork of istanbul instead of gulp-coffee-istanbul:

./node_modules/.bin/istanbul cover ./node_modules/.bin/_mocha -- --compilers coffee:coffee-script/register test/*.coffee

[thom-nic]

@justin-lau @duereg is there an open PR to have those changes to istanbul merged upstream?

[duereg]

@thom-nic @justin-lau There is an open pull request on istanbul that I used as the basis for my fork. But it's been hanging around since March with no ETA on a merge.

[gilligan]

@justin-lau @duereg sorry for reviving this - i am trying to figure out how to get this istanbul fork to work since this still hasn't been merge upstream. When I try the command you listed @justin-lau I still get "No coverage information output was collected, exit without coverage information"

Can either of you perhaps help me out with this ? :) thanks.

[duereg]

@gilligan You figured this out, correct?

[gilligan]

@duereg yep thanks ;-)

[jwalton]

Just wanted to drop a note mentioning that coffee-coverage has support for Istanbul instrumentation now, and it was designed from the ground up with mocha in mind.

[59naga]

Got the answer of ibrik:

$ ibrik cover _mocha -- test/*.coffee

Note:
test/**" isn't calculated. Can use --default-excludes option if want include files at test/**
