# Codecov GitHub Action 

[![GitHub Marketplace](https://img.shields.io/badge/Marketplace-v1.0.4-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 macOS and Windows builds!

## Usage

To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number as a `step` within your `workflow.yml` file. 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 five additional inputs to customize the upload context.

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

```yaml
steps:
- uses: actions/checkout@master
- uses: codecov/codecov-action@v1
  with:
    token: ${{ secrets.CODECOV_TOKEN }} #required
    file: ./coverage.xml #optional
    flags: unittests #optional
    name: codecov-umbrella #optional
    yml: ./codecov.yml #optional
    fail_ci_if_error: yes #optional (default = no)
```
>**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). 

## Arguments

Codecov's Action currently supports five inputs from the user: `token`, `file`, `flags`,`name`, `yml`, and `fail_ci_if_error`. These inputs, along with their descriptions and usage contexts, are listed in the table below: 

| Input  | Description | Usage |
| :---:     |     :---:   |    :---:   |
| `token`  | Used to authorize coverage report uploads  | *Required* |
| `file`  | Path to the coverage report(s) | Optional
| `flags`  | Flag the upload to group coverage metrics (unittests, uitests, etc.) | Optional
| `name`  | Custom defined name for the upload | Optional
| `yml`  | Path to codecov.yml config file | Optional
| `fail_ci_if_error`  | Specify whether CI pipeline should fail if there are errors related to Codecov. *Defaults to no*. | Optional
