v5 of the Codecov GitHub Action will use the Codecov Wrapper to encapsulate the CLI. This will help ensure that the Action gets updates quicker.

The v5 release also coincides with the opt-out feature for tokens for public repositories. In the Global Upload Token section of the settings page of an organization in codecov.io, you can set the ability for Codecov to receive a coverage reports from any source. This will allow contributors or other members of a repository to upload without needing access to the Codecov token. For more details see how to upload without a token.

The following arguments have been added:

• binary
• gcov_args
• gcov_executable
• gcov_ignore
• gcov_include
• report_type
• skip_validation
• swift_project

You can see their usage in the action.yml file.

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

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

• 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).

To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number (@v5 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@v5
  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 }}
    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@v5
  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 }}

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@v5
  with:
    use_oidc: true

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

Codecov's Action supports inputs from the user. These inputs, along with their descriptions and usage contexts, are listed in the table below:

    runs-on: ${{ matrix.os }}

    env:
      OS: ${{ matrix.os }}
      PYTHON: '3.10'
    steps:
    - uses: actions/checkout@main
