## Example github action tests in created PRs
## Running GitHub Actions CI
By default, this action uses an api token provided by github ci to create the
pull request. By default, Github does not run github actions, i.e. tests, for
these types of pull requests. However, you can bypass this restriction by
specifying a personal authentication token (PAT). You can create a token by
visiting [https://github.com/settings/tokens]() and select at least the scope
`repo`. Then store this token in your repository secrets (i.e.
'https://github.com/<USER>/<REPO>/settings/secrets/actions') as
`GH_TOKEN_FOR_UPDATES`.
GitHub Actions will not run workflows when a branch is pushed by or a PR is opened by a GitHub Action. There are two ways to have GitHub Actions CI run on a PR submitted by this action.
### Without a Personal Authentication Token
Without using a Personal Authentication Token, you can manually run the following to kick off a CI run:
```
git branch -D update_flake_lock_action
git fetch origin
git checkout update_flake_lock_action
git commit --amend --no-edit
git push origin update_flake_lock_action --force
```
### With a Personal Authentication Token
By providing a Personal Authentication Token, the PR will be submitted in a way that bypasses this limitation (GitHub will essentially think it is the owner of the PAT submitting the PR, and not an Action).
You can create a token by visiting https://github.com/settings/tokens and select at least the `repo` scope. Then, store this token in your repository secrets (i.e. 'https://github.com/<USER>/<REPO>/settings/secrets/actions') as `GH_TOKEN_FOR_UPDATES` and set up your workflow file like the following:
```yaml
name: update-flake-lock

## Running GitHub Actions CI
GitHub Actions will not run workflows when a branch is pushed by or a PR is opened by a GitHub Action. To work around this, try:
```
git branch -D update_flake_lock_action
git fetch origin
git checkout update_flake_lock_action
git commit --amend --no-edit
git push origin update_flake_lock_action --force
```
