5[Coveralls.io](https://coveralls.io/) support for Node.js. Get the great coverage reporting of coveralls.io and add a cool coverage button (like the one above) to your README.

7Supported CI services: [Travis CI](https://travis-ci.org/), [CodeShip](https://codeship.com/), [CircleCI](https://circleci.com/), [Jenkins](https://jenkins.io/), [Gitlab CI](https://gitlab.com/), [AppVeyor](https://www.appveyor.com/), [Buildkite](https://buildkite.com/), [GitHub Actions CI](https://github.com/features/actions), [CodeFresh](https://codefresh.io)

9## Installation:
10
11Add the latest version of `coveralls` to your package.json:
12
13```shell
14npm install coveralls --save-dev
15```
16
17If you're using mocha, add `mocha-lcov-reporter` to your package.json:
18
19```shell
20npm install mocha-lcov-reporter --save-dev
21```
22
23## Usage:
24
25This script `bin/coveralls.js` can take standard input from any tool that emits the lcov data format (including [mocha](https://mochajs.org/)'s [LCOV reporter](https://npmjs.org/package/mocha-lcov-reporter)) and send it to coveralls.io to report your code coverage there.
26
27Once your app is instrumented for coverage, and building, you need to pipe the lcov output to `./node_modules/coveralls/bin/coveralls.js`.
28
29This library currently supports [Travis CI](https://travis-ci.org/) with no extra effort beyond piping the lcov output to coveralls. However, if you're using a different build system, there are a few environment variables that are necessary:
30
31- `COVERALLS_SERVICE_NAME` (the name of your build system)
32- `COVERALLS_REPO_TOKEN` (the secret repo token from coveralls.io)
33- `COVERALLS_GIT_BRANCH` (the branch name)
34
35There are optional environment variables for other build systems as well:
36
37- `COVERALLS_SERVICE_NUMBER` (an id that uniquely identifies the build)
38- `COVERALLS_SERVICE_JOB_ID` (an id that uniquely identifies the build's job)
39- `COVERALLS_RUN_AT` (a date string for the time that the job ran. RFC 3339 dates work. This defaults to your build system's date/time if you don't set it.)
40- `COVERALLS_PARALLEL` (more info here: <https://docs.coveralls.io/parallel-build-webhook>)
41
42### GitHub Actions CI
43
44If you are using GitHub Actions CI, you should look into [coverallsapp/github-action](https://github.com/coverallsapp/github-action).
45
46If you prefer to use this package you can do it like this:
47
48```yml
49env:
50 COVERALLS_REPO_TOKEN: "${{ secrets.COVERALLS_REPO_TOKEN }}"
51 COVERALLS_GIT_BRANCH: "${{ github.ref }}"
52```
53
54### [Jest](https://jestjs.io/)
55
56- Install [jest](https://jestjs.io/docs/en/getting-started)
57- Use the following to run tests and push files to coveralls on success:
58
59 ```sh
60 jest --coverage && coveralls < coverage/lcov.info
61 ```
62
63Check out an example [here](https://github.com/Ethan-Arrowood/harperdb-connect/blob/master/.travis.yml) which makes use of Travis CI build stages
64
65### [Mocha](https://mochajs.org/) + [Blanket.js](https://github.com/alex-seville/blanket)
66
67- Install [blanket.js](https://github.com/alex-seville/blanket)
68- Configure blanket according to [docs](https://github.com/alex-seville/blanket/blob/master/docs/getting_started_node.md).
69- Run your tests with a command like this:
70
71 ```sh
72 NODE_ENV=test YOURPACKAGE_COVERAGE=1 ./node_modules/.bin/mocha \
73 --require blanket \
74 --reporter mocha-lcov-reporter | ./node_modules/coveralls/bin/coveralls.js
75 ```
76
77### [Mocha](https://mochajs.org/) + [JSCoverage](https://github.com/fishbar/jscoverage)
78
79Instrumenting your app for coverage is probably harder than it needs to be (read [here](http://seejohncode.com/2012/03/13/setting-up-mocha-jscoverage//)), but that's also a necessary step.
80
81In mocha, if you've got your code instrumented for coverage, the command for a Travis CI build would look something like this:
82
83```sh
84YOURPACKAGE_COVERAGE=1 ./node_modules/.bin/mocha test -R mocha-lcov-reporter | ./node_modules/coveralls/bin/coveralls.js
85```
86
87Check out an example [Makefile](https://github.com/cainus/urlgrey/blob/master/Makefile) from one of my projects for an example, especially the test-coveralls build target. Note: Travis CI runs `npm test`, so whatever target you create in your Makefile must be the target that `npm test` runs (This is set in package.json's `scripts` property).
88
89### [Istanbul](https://github.com/gotwarlost/istanbul)
90
91#### With Mocha:
92
93```sh
94istanbul cover ./node_modules/mocha/bin/_mocha --report lcovonly -- -R spec && cat ./coverage/lcov.info | ./node_modules/coveralls/bin/coveralls.js && rm -rf ./coverage
95```
96
97#### With Jasmine:
98
99```sh
100istanbul cover jasmine-node --captureExceptions spec/ && cat ./coverage/lcov.info | ./node_modules/coveralls/bin/coveralls.js && rm -rf ./coverage
101```
102
103### [Nodeunit](https://github.com/caolan/nodeunit) + [JSCoverage](https://github.com/fishbar/jscoverage)
104
105Depend on nodeunit, jscoverage and coveralls:
106
107```sh
108npm install nodeunit jscoverage coveralls --save-dev
109```
110
111Add a coveralls script to "scripts" in your `package.json`:
112
113```json
114"scripts": {
115 "test": "nodeunit test",
116 "coveralls": "jscoverage lib && YOURPACKAGE_COVERAGE=1 nodeunit --reporter=lcov test | coveralls"
117}
118```
119
120Ensure your app requires instrumented code when `process.env.YOURPACKAGE_COVERAGE` variable is defined.
121
122Run your tests with a command like this:
123
124```sh
125npm run coveralls
126```
127
128For detailed instructions on requiring instrumented code, running on Travis CI and submitting to coveralls [see this guide](https://github.com/alanshaw/nodeunit-lcov-coveralls-example).
129
130### [Poncho](https://github.com/deepsweet/poncho)
131
132Client-side JS code coverage using [PhantomJS](https://github.com/ariya/phantomjs), [Mocha](https://mochajs.org/) and [Blanket](https://github.com/alex-seville/blanket):
133
134- [Configure](https://mochajs.org/#running-mocha-in-the-browser) Mocha for browser
135- [Mark](https://github.com/deepsweet/poncho#usage) target script(s) with `data-cover` HTML attribute
136- Run your tests with a command like this:
137
138 ```sh
139 ./node_modules/.bin/poncho -R lcov test/test.html | ./node_modules/coveralls/bin/coveralls.js
140 ```
141
142### [Lab](https://github.com/hapijs/lab)
143
144```sh
145lab -r lcov | ./node_modules/.bin/coveralls
146```
147
148### [nyc](https://github.com/istanbuljs/nyc)
149
150Works with almost any testing framework. Simply execute
151`npm test` with the `nyc` bin followed by running its reporter:
152
153```shell
154nyc npm test && nyc report --reporter=text-lcov | coveralls
155```
156
157### [TAP](https://github.com/isaacs/node-tap)
158
159Simply run your tap tests with the `COVERALLS_REPO_TOKEN` environment
160variable set and tap will automatically use `nyc` to report
161coverage to coveralls.
162
163### Command Line Parameters
164
165```shell
166Usage: coveralls.js [-v] filepath
167```
168
169#### Optional arguments:
170
171- `-v`, `--verbose`
172- `filepath` - optionally defines the base filepath of your source files.
173
174## Running locally
175
176If you're running locally, you must have a `.coveralls.yml` file, as documented in [their documentation](https://docs.coveralls.io/ruby-on-rails#configuration), with your `repo_token` in it; or, you must provide a `COVERALLS_REPO_TOKEN` environment variable on the command-line.
177
178If you want to send commit data to coveralls, you can set the `COVERALLS_GIT_COMMIT` environment-variable to the commit hash you wish to reference. If you don't want to use a hash, you can set it to `HEAD` to supply coveralls with the latest commit data. This requires git to be installed and executable on the current PATH.
179
180## Contributing
181
182I generally don't accept pull requests that are untested, or break the build, because I'd like to keep the quality high (this is a coverage tool after all!).
183
184I also don't care for "soft-versioning" or "optimistic versioning" (dependencies that have ^, x, > in them, or anything other than numbers and dots). There have been too many problems with bad semantic versioning in dependencies, and I'd rather have a solid library than a bleeding edge one.
