Codecov GitHub Action

Easily upload coverage reports to Codecov from GitHub Actions

v4 Release

v4 of the Codecov GitHub Action will use the Codecov CLI to upload coverage reports to Codecov.

Breaking Changes

• Tokenless uploading is unsupported. However, PRs made from forks to the upstream public repos will support tokenless (e.g. contributors to OS projects do not need the upstream repo's Codecov token). For details, see our docs
• Various arguments to the Action have been removed

Dependabot

• For repositories using Dependabot, users will need to ensure that it has access to the Codecov token for PRs from Dependabot to upload coverage. To do this, please add your CODECOV_TOKEN as a Dependabot Secret. For more information, see "Configuring access to private registries for Dependabot."

v3 versions and below will not have access to CLI features (e.g. global upload token, ATS).

Usage

To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number (@v4 is recommended) as a step within your workflow.yml file.

This Action also requires you to provide an upload token from codecov.io (tip: in order to avoid exposing your token, store it as a secret).

Currently, the Action will identify linux, macos, and windows runners. However, the Action may misidentify other architectures. The OS can be specified as

• alpine
• alpine-arm64
• linux
• linux-arm64
• macos
• windows

Inside your .github/workflows/workflow.yml file:

steps:
- uses: actions/checkout@main
- uses: codecov/codecov-action@v4
  with:
    fail_ci_if_error: true # optional (default = false)
    files: ./coverage1.xml,./coverage2.xml # optional
    flags: unittests # optional
    name: codecov-umbrella # optional
    token: ${{ secrets.CODECOV_TOKEN }} # required
    verbose: true # optional (default = false)

The Codecov token can also be passed in via environment variables:

steps:
- uses: actions/checkout@main
- uses: codecov/codecov-action@v4
  with:
    fail_ci_if_error: true # optional (default = false)
    files: ./coverage1.xml,./coverage2.xml # optional
    flags: unittests # optional
    name: codecov-umbrella # optional
    verbose: true # optional (default = false)
  env:
    CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }}

Note

This assumes that you've set your Codecov token inside Settings > Secrets as CODECOV_TOKEN. If not, you can get an upload token for your specific repo on codecov.io. Keep in mind that secrets are not available to forks of repositories.

Using OIDC

For users with OpenID Connect(OIDC) enabled, the Codecov token is not necessary. You can use OIDC with the use_oidc argument as following.

- uses: codecov/codecov-action@v4
  with:
    use_oidc: true

Any token supplied will be ignored, as Codecov will default to the OIDC token for verification.
