feat: implement Istanbul reporting #8

Merged

bcoe merged 6 commits into master from implement-reporting

Dec 5, 2017

Owner

bcoe commented Dec 1, 2017

using various bits of nyc as a foundation this pull request implements outputting v8 coverage information through Istanbul's reporters.

As an example, the following:

./bin/c8.js --reporter html test/fixtures/a.js

Outputs an HTML report in ./coverage/index.html that looks like this:

I recommend running a canary version of Node.js to see all the fancy new coverage features in action.

The rest looks great

+                const tmpDirctory = resolve(argv.coverageDirectory, './tmp')
+                rimraf.sync(tmpDirctory)

Not like it matters much, but can you use asynchronous I/O if possible?

* Node.js' source-map and lineLength cache is now used to remap coverage output (this allows tools like ts-node to be supported, which transpile at runtime).
* temp directory now defaults to setting for report directory
* c8 will now load source-maps if possible and remap coverage accordingly
* switches to using NODE_V8_COVERAGE rather than inspector directly
* dropped subprocess support for the time being, while we march towards an initial implementation.

### BREAKING CHANGES

* Node.js' source-map and lineLength cache is now used to remap coverage output (this allows tools like ts-node to be supported, which transpile at runtime).
* temp directory now defaults to setting for report directory
* c8 will now load source-maps if possible and remap coverage accordingly
* switches to using NODE_V8_COVERAGE rather than inspector directly
* dropped subprocess support for the time being, while we march towards an initial implementation.
