Coverage with NYC about ava-ts HOT 10 OPEN

Hmm, here's my nyc config now:

{
    "include": [
      "src/**/*.ts"
    ],
    "exclude": [
      "**/*.d.ts"
    ],
    "extension": [
      ".ts"
    ],
    "require": [
      "ts-node/register"
    ],
    "reporter": [
      "html",
      "text"
    ],
    "sourceMap": false,
    "instrument": true,
    "all": true
}

This seems to find all of my files (the require option is necessary in addition to the all key), but does not register my coverage for any except one of the files.

@sigmasoldi3r Ava supports .ts files now (and coverage reports are working for me too).

Thanks for sharing, @Harangue! :)

Runs without crashing for me, too, but I don't get any coverage in my test project... (Source files are matched by src/**/*.ts in my project as well)

Hey @wbhob. Excellent point...

I played around and tried a bunch of stuff, but the bad news is I am currently not able to get working coverage reports either 😕

Some of the code transparently added by TypeScript or NYC just crashs with TypeError: Promise resolver undefined is not a function.

So this is an unsolved issue as of now.

I got this working! Here's my .nycrc

{
  "extension": [
    ".ts",
    ".tsx"
  ],
  "include": ["src/**/*.ts"],
  "reporter": [
    "text",
    "html"
  ],
  "cache": true,
  "sourceMap": false,
  "instrument": false
}

Then I run

nyc ava-ts tests/ --verbose

I haven't had any issues with this method whatsoever. :)

Yeah @andywer, it seems I spoke too soon. I got it to run test coverage for all of my files once, somehow, but never again after that. I've been looking at this blog post to try to uncover what's wrong but I'm afraid I don't understand all of the mechanics of how ava reports to instanbul.

from ava-ts.

in my case NYC is ignoring the coverage from tests

$ nyc ava-ts tests --verbose

@jack-guy yes but if you are using babel 7 + typescript then you are still tends on ava-ts. I didn't find different solution. Can you be more explicit about support of ts files?

from ava-ts.

When I exclude:

"exclude": [
      "**/*.d.ts"
    ],

I am seeing this error:

TSError: ⨯ Unable to compile TypeScript
src/app.ts (84,29): Argument of type 'string | undefined' is not assignable to parameter of type 'string'.

from ava-ts.

@dougmolineux Still hard to tell if this has to do with AVA-TS or just TypeScript... Are you talking about an exclude in the tsconfig.json or in the ava config in the package.json?
