nyc not generating report

Link to bug Demo repo: https://github.com/mega6382/nyc-bug-demo

I am using nyc with mocha to generate reports for my tests in html and lcov, it was working fine until recently but then it suddenly stopped working even though I haven’t changed anything.

Expected Behavior

Tests should run and return a proper test report in html and lcov

Observed Behavior

No report is generated

Environment Information

Node v10.15.1 Npm 6.9.0 run the following script:

  npm install
  npm test

Here is the out put that I get now:

  Test Express Server on 3000 port
    √ Send Request(Server Test)


  1 passing (62ms)

@mega6382 yes. I believe you need to configure extension to nyc:

  "nyc": {
    "exclude": [
      "**/sentryHelper.*",
      "**/*.test.*"
    ],
    "extension": [
       ".ts"
    ],
    "reporter": [
      "lcov",
      "text"
    ]
},

nyc@14 requires that extension match the original source filename (.ts in your case). In nyc@15 the extension option will include .ts by default.

@coreyfarrell Thanks, just checked and it seems that i updated nyc 11 days ago from 13.3.0 to 14.1.1 and it probably started failing after that.

Thanks for your help, it is working now.
