### Easily upload coverage reports to Codecov from GitHub Actions

>The latest release of this Action adds support for tokenless uploads from GitHub Actions!

## ⚠️  Deprecation of v1
**As of February 1, 2022, v1 has been fully sunset and no longer functions**

Due to the [deprecation](https://about.codecov.io/blog/introducing-codecovs-new-uploader/) of the underlying bash uploader,
the Codecov GitHub Action has released `v2`/`v3` which will use the new [uploader](https://github.com/codecov/uploader). You can learn
more about our deprecation plan and the new uploader on our [blog](https://about.codecov.io/blog/introducing-codecovs-new-uploader/).

We will be restricting any updates to the `v1` Action to security updates and hotfixes.

### Migration from `v1` to `v3`
The `v3` uploader has a few breaking changes for users
- Multiple fields have not been transferred from the bash uploader or have been deprecated. Notably
many of the `functionalities` and `gcov_` arguments have been removed. Please check the documentation
below for the full list.

## Usage

To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number (`@v3` is recommended) as a `step` within your `workflow.yml` file.

If you have a *private repository*, this Action also requires you to [provide an upload token](https://docs.codecov.io/docs/frequently-asked-questions#section-where-is-the-repository-upload-token-found-) from [codecov.io](https://www.codecov.io) (tip: in order to avoid exposing your token, store it as a `secret`). Optionally, you can choose to include up to four additional inputs to customize the upload context. **For public repositories, no token is needed**

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

```yaml
steps:
- uses: actions/checkout@master
- uses: codecov/codecov-action@v3
  with:
    token: ${{ secrets.CODECOV_TOKEN }} # not required for public repos
    files: ./coverage1.xml,./coverage2.xml # optional
    flags: unittests # optional
    name: codecov-umbrella # optional
    fail_ci_if_error: true # optional (default = false)
    verbose: true # optional (default = false)
```
>**Note**: This assumes that you've set your Codecov token inside *Settings > Secrets* as `CODECOV_TOKEN`. If not, you can [get an upload token](https://docs.codecov.io/docs/frequently-asked-questions#section-where-is-the-repository-upload-token-found-) for your specific repo on [codecov.io](https://www.codecov.io). Keep in mind that secrets are *not* available to forks of repositories.

## Arguments

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

| Input  | Description | Usage |

| `override_branch` | Specify the branch name | Optional
| `override_build` | Specify the build number | Optional
| `override_commit` | Specify the commit SHA | Optional
| `override_pr` | Specify the pull request number | Optional
