Codecov Scala Example

Guide

GitHub Actions Setup

You should first get the repository upload token from codecov

Add the following to your .github/workflows/test.yml file.

name: Test workflow

on: [push, pull_request]

jobs:
  build:
    runs-on: ubuntu-latest
    name: Test scala
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-java@v4
        with:
          distribution: 'adopt'
          java-version: '21'
      - name: Run tests
        run: sbt coverage test coverageReport
      - uses: codecov/codecov-action@v4
        with:
          fail_ci_if_error: true
          token: ${{ secrets.CODECOV_TOKEN }}

Here we frist checkout the code, then setup java, run the tests and generate the coverage report. Finally, we upload the report to codecov using the codecov-action.

When all finished, you could also add a badge on readme like following.

Produce Coverage Reports

1. Add scoverage to plugin list

• addSbtPlugin("org.scoverage" % "sbt-scoverage" % "2.0.11") as seen here

1. Add coverage and coverageReport to sbt

• sbt clean coverage test coverageReport as seen here

Caveats

Private Repo

Repository tokens are required for

• (a) all private repos,
• (b) public repos not using Travis-CI, CircleCI or AppVeyor.

Find your repository token at Codecov and provide via appending -t <your upload token> to you where you upload reports.
