# Codecov GitHub Action 

[![GitHub Marketplace](https://img.shields.io/badge/Marketplace-v1-undefined.svg?logo=github&logoColor=white&style=flat)](https://github.com/marketplace/actions/codecov)
### Easily upload coverage reports to Codecov from GitHub Actions 

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

## Usage

To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number (`@v1` 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@v1
  with:
    token: ${{ secrets.CODECOV_TOKEN }} # not required for public repos
    file: ./coverage.xml # optional
    flags: unittests # optional
    name: codecov-umbrella # optional
    fail_ci_if_error: 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 currently supports five inputs from the user: `token`, `file`, `flags`,`name`, and `fail_ci_if_error`. These inputs, along with their descriptions and usage contexts, are listed in the table below: 

>**Update**: We've removed the `yml` paramter with the latest release of this action. Please put your custom codecov yaml file at the root of the repo because other locations will no longer be supported in the future.

| Input  | Description | Usage |
| :---:     |     :---:   |    :---:   |
| `token`  | Used to authorize coverage report uploads  | *Required for private repos* |
| `file`  | Path to the coverage report(s) | Optional
| `flags`  | Flag the upload to group coverage metrics (unittests, uitests, etc.). Multiple flags are separated by a comma (ui,chrome) | Optional
| `name`  | Custom defined name for the upload | Optional
| `fail_ci_if_error`  | Specify if CI pipeline should fail when Codecov runs into errors during upload. *Defaults to **false*** | Optional
