Node Codacy Coverage

Credits to David for creating this! Codacy support for Node.js. Get coverage reporting and code analysis for Node.js from Codacy.

Installation

Add the latest version of codacy-coverage to your package.json:

npm install codacy-coverage --save

If you're using mocha, add mocha-lcov-reporter to your package.json:

npm install mocha-lcov-reporter --save

Enterprise

To send coverage in the enterprise version you should specify your Codacy installation URL with the option -e:

codacy-coverage -e <YOUR-CODACY-ENTERPRISE-URL>:16006

Usage

This cli can take standard input from any tool that emits the lcov data format (including mocha's LCov reporter) and send it to Codacy to report your code coverage there.

Once your app is instrumented for coverage, and building, you need to pipe the lcov output to codacy-coverage.

Identifying the project

You'll need to provide the secret Project API token from Codacy Project > Settings > Integrations > Project API via:

• (Recommended) Environment variable: CODACY_PROJECT_TOKEN
• CLI parameter variable: --token

Note: You should keep your any API token well protected, as it grants owner permissions to your projects.

Test Coverage

Mocha + Blanket.js

• Install blanket.js
• Configure blanket according to docs.
• Add test with coverage step to your package.json:

"scripts": {
  "test-with-coverage": "NODE_ENV=test YOURPACKAGE_COVERAGE=1 mocha --require blanket --reporter mocha-lcov-reporter | codacy-coverage"
}

• Run your tests with:

npm run test-with-coverage

Mocha + JSCoverage

Instrumenting your app for coverage is probably harder than it needs to be (read here), but that's also a necessary step.

• Add test with coverage step to your package.json:

"scripts": {
  "test-with-coverage": "YOURPACKAGE_COVERAGE=1 mocha test -R mocha-lcov-reporter | codacy-coverage"
}

• Run your tests with:

npm run test-with-coverage

Istanbul

With Mocha

• Add test with coverage step to your package.json:

"scripts": {
  "test-with-coverage": "istanbul cover _mocha --report lcovonly -- -R spec && cat ./coverage/lcov.info | codacy-coverage && rm -rf ./coverage"
}

• Run your tests with:

npm run test-with-coverage

With Jasmine

• Add test with coverage step to your package.json:

"scripts": {
  "test-with-coverage": "istanbul cover jasmine-node --captureExceptions spec/ && cat ./coverage/lcov.info | codacy-coverage && rm -rf ./coverage"
}

• Run your tests with:

npm run test-with-coverage

Poncho

Client-side JS code coverage using PhantomJS, Mocha and Blanket:

• Configure Mocha for browser
• Mark target script(s) with data-cover html-attribute
• Add test with coverage step to your package.json:

"scripts": {
  "test-with-coverage": "poncho -R lcov test/test.html | codacy-coverage"
}

• Run your tests with:

npm run test-with-coverage

Jest

• Add test with coverage step to your package.json:

Note: jest might return exit code 1 if you defined a coverage threshold and the threshold is not met

"scripts": {
  "test-with-coverage": "jest --coverage && cat ./coverage/lcov.info | codacy-coverage"
}

• Run your tests with:

npm run test-with-coverage

Extras

Account Token

As an alternative to the Project API token you can also send coverage using your account/api token by following steps:

• Add test with coverage step to your package.json:

"scripts": {
  "test-with-coverage": "cat ./coverage/lcov.info | codacy-coverage --accountToken <account-token> --username <username> --projectName <project-name>"
}

• Run your tests with:

npm run test-with-coverage

You'll need to provide the secret Account API token from Codacy Account > API Tokens via:

• (Recommended) Environment variable: CODACY_ACCOUNT_TOKEN
• CLI parameter variable: --accountToken

Force custom language (e.g. Typescript, Coffeescript, C, ...)

• Pass an extra parameter to the codacy-coverage reporter --language typescript or --language coffeescript.
• If you have multiple languages you need to invoke the reporter for each of them.

Run in Windows

If you are running coverage in a windows machine without Unix tools, you need to change the command to codacy-coverage < ./test/unit/coverage/lcov.info.

Troubleshooting

Path Problems

The paths in your coverage file should be relative, if you are having problems with absolute paths, you can run our plugin with -p . to strip the current path from the paths in your coverage file:

"scripts": {
  "test-with-coverage": "cat ./coverage/lcov.info | codacy-coverage -p ."
}

Enterprise Coverage

To send coverage in the enterprise version you should specify your Codacy installation URL followed by the port 16006 using the -e option, example:

"scripts": {
  "test-with-coverage": "cat ./coverage/lcov.info | codacy-coverage -e <YOUR-CODACY-ENTERPRISE-URL>:16006"
}
