goveralls

=========



[Go](http://golang.org) integration for [Coveralls.io](http://coveralls.io)

continuous code coverage tracking system.



# Installation



`goveralls` requires a working Go installation (Go-1.13 or higher).



```bash

$ go install github.com/mattn/goveralls@latest

```



# Usage



First you will need an API token.  It is found at the bottom of your

repository's page when you are logged in to Coveralls.io.  Each repo has its

own token.



```bash

$ cd $GOPATH/src/github.com/yourusername/yourpackage

$ goveralls -repotoken your_repos_coveralls_token

```



You can set the environment variable `$COVERALLS_TOKEN` to your token so you do

not have to specify it at each invocation.



You can also run this reporter for multiple passes with the flag `-parallel` or

by setting the environment variable `COVERALLS_PARALLEL=true` (see [coveralls

docs](https://docs.coveralls.io/parallel-build-webhook) for more details).



# Continuous Integration



There is no need to run `go test` separately, as `goveralls` runs the entire

test suite.



## GitHub Actions



[shogo82148/actions-goveralls](https://github.com/marketplace/actions/actions-goveralls) is available on GitHub Marketplace.

It provides the shorthand of the GitHub Actions YAML configure.



```yaml

name: Quality

on: [push, pull_request]

jobs:

  test:

    name: Test with Coverage

    runs-on: ubuntu-latest

    steps:

    - name: Set up Go

      uses: actions/setup-go@v2

      with:

        go-version: '1.16'

    - name: Check out code

      uses: actions/checkout@v2

    - name: Install dependencies

      run: |

        go mod download

    - name: Run Unit tests

      run: |

        go test -race -covermode atomic -coverprofile=covprofile ./...

    - name: Install goveralls

      run: go install github.com/mattn/goveralls@latest

    - name: Send coverage

      env:

        COVERALLS_TOKEN: ${{ secrets.GITHUB_TOKEN }}

      run: goveralls -coverprofile=covprofile -service=github

    # or use shogo82148/actions-goveralls

    # - name: Send coverage

    #   uses: shogo82148/actions-goveralls@v1

    #   with:

    #     path-to-profile: covprofile

```



## Travis CI



### GitHub Integration



Enable Travis-CI on your GitHub repository settings.



For a **public** GitHub repository put bellow's `.travis.yml`.



```yml

language: go

go:

  - tip

before_install:

  - go install github.com/mattn/goveralls@latest

script:

  - $GOPATH/bin/goveralls -service=travis-ci

```



For a **public** GitHub repository, it is not necessary to define your repository key (`COVERALLS_TOKEN`).



For a **private** GitHub repository put bellow's `.travis.yml`. If you use **travis pro**, you need to specify `-service=travis-pro` instead of `-service=travis-ci`.



```yml

language: go

go:

  - tip

before_install:

  - go install github.com/mattn/goveralls@latest

script:

  - $GOPATH/bin/goveralls -service=travis-pro

```



Store your Coveralls API token in `Environment variables`.



```

COVERALLS_TOKEN = your_token_goes_here

```



or you can store token using [travis encryption keys](https://docs.travis-ci.com/user/encryption-keys/). Note that this is the token provided in the page for that specific repository on Coveralls. This is *not* one that was created from the "Personal API Tokens" area under your Coveralls account settings.



```

$ gem install travis

$ travis encrypt COVERALLS_TOKEN=your_token_goes_here --add env.global

```



travis will add `env` block as following example:



```yml

env:

  global:

    secure: xxxxxxxxxxxxx

```



### For others:



```

$ go install github.com/mattn/goveralls@latest

$ go test -covermode=count -coverprofile=profile.cov

$ goveralls -coverprofile=profile.cov -service=travis-ci

```



## Drone.io



Store your Coveralls API token in `Environment Variables`:



```

COVERALLS_TOKEN=your_token_goes_here

```



Replace the `go test` line in your `Commands` with these lines:



```

$ go install github.com/mattn/goveralls@latest

$ goveralls -service drone.io

```



`goveralls` automatically use the environment variable `COVERALLS_TOKEN` as the

default value for `-repotoken`.



You can use the `-v` flag to see verbose output from the test suite:



```

$ goveralls -v -service drone.io

```



## CircleCI



Store your Coveralls API token as an [Environment Variable](https://circleci.com/docs/environment-variables).



In your `circle.yml` add the following commands under the `test` section.



```yml

test:

  pre:

    - go install github.com/mattn/goveralls@latest

  override:

    - go test -v -cover -race -coverprofile=/home/ubuntu/coverage.out

  post:

    - /home/ubuntu/.go_workspace/bin/goveralls -coverprofile=/home/ubuntu/coverage.out -service=circle-ci -repotoken=$COVERALLS_TOKEN

```



For more information, See https://docs.coveralls.io/go



## Semaphore



Store your Coveralls API token in `Environment Variables`:



```

COVERALLS_TOKEN=your_token_goes_here

```



More instructions on how to do this can be found in the [Semaphore documentation](https://semaphoreci.com/docs/exporting-environment-variables.html).



Replace the `go test` line in your `Commands` with these lines:



```

$ go install github.com/mattn/goveralls@latest

$ goveralls -service semaphore

```



`goveralls` automatically use the environment variable `COVERALLS_TOKEN` as the

default value for `-repotoken`.



You can use the `-v` flag to see verbose output from the test suite:



```

$ goveralls -v -service semaphore

```



## Jenkins CI



Add your Coveralls API token as a credential in Jenkins (see [Jenkins documentation](https://www.jenkins.io/doc/book/using/using-credentials/#configuring-credentials)).



Then declare it as the environment variable `COVERALLS_TOKEN`:

```groovy

pipeline {

    agent any

    stages {

        stage('Test with coverage') {

            steps {

                sh 'go test ./... -coverprofile=coverage.txt -covermode=atomic'

            }

        }

        stage('Upload to coveralls.io') {

            environment {

                COVERALLS_TOKEN     = credentials('coveralls-token')

            }

            steps {

                sh 'goveralls -coverprofile=coverage.txt'

            }

        }

    }

}

```



See also [related Jenkins documentation](https://www.jenkins.io/doc/book/pipeline/jenkinsfile/#for-secret-text-usernames-and-passwords-and-secret-files).



It is also possible to let goveralls run the code coverage on its own without providing a coverage profile file.



## TeamCity



Store your Coveralls API token in `Environment Variables`:



```

COVERALLS_TOKEN=your_token_goes_here

```



Setup build steps:



```

$ go install github.com/mattn/goveralls@latest

$ export PULL_REQUEST_NUMBER=%teamcity.build.branch%

$ goveralls -service teamcity -jobid %teamcity.build.id% -jobnumber %build.number%

```



`goveralls` will automatically use the environment variable `COVERALLS_TOKEN` as the

default value for `-repotoken`.



You can use the `-v` flag to see verbose output.



## Gitlab CI



Store your Coveralls API token as an [Environment Variable](https://docs.gitlab.com/ee/ci/variables/#create-a-custom-variable-in-the-ui) named `COVERALLS_TOKEN`.



```yml

test:

  timeout: 30m

  stage: test

  artifacts:

    paths:

      - coverage.txt

  dependencies:

    - build:env

  when: always

  script:

    - go test -covermode atomic -coverprofile=coverage.txt ./...

    - go install github.com/mattn/goveralls@latest

    - goveralls -service=gitlab -coverprofile=coverage.txt

```



## Coveralls Enterprise



If you are using Coveralls Enterprise and have a self-signed certificate, you need to skip certificate verification:



```shell

$ goveralls -insecure

```
