# Contributing to the google.cloud collection

## Workflow summary

1. [Clone the repository](#cloning).
1. Make the desired code change.
1. Add a [changelog fragment](https://docs.ansible.com/ansible/devel/community/development_process.html#changelogs-how-to) to describe your change.
1. [Run integration tests locally and ensure they pass](running-integration-tests).
1. Create a PR.

## Cloning

The `ansible-test` command expects that the repository is in a directory that matches it's collection,
under a directory `ansible_collections`. Clone ensuring that hierarchy:

```shell
mkdir -p $TARGET_DIR/ansible_collections/google
git clone <url> $TARGET_DIR/collections/google/cloud
```

## Running tests

### prequisites for all tests

- Install the `ansible` package.
- Some container runtime is necessary (e.g. `podman` or `docker`). The instructions use podman.

## Running integration tests

### Integration testing prequisites

#### Installing personal GCP credentials

The integration tests for this module require the use of real GCP credentials, and must provide
ansible-test those values. They can be added by authoring the following in `tests/integration/cloud-config-gcp.ini`:

```
[default]
gcp_project: @PROJECT_ID
gcp_cred_file: @CRED_FILE
gcp_cred_kind: @CRED_KIND
gcp_cred_email: @EMAIL
gcp_folder_id: @TEST_FOLDER (to create test projects)
```

#### Setting up the project for testing

Some of the setup of the project itself is done outside of the test,
and is expected to be configured beforehand.

For convenience, a bootstrap script is provided.

NOTE: running this script will make irreversible changes in your
GCP project (e.g. create an AppEngine project):

```bash
bash ./scripts/bootstrap-project.sh $PROJECT_ID $SERVICE_ACCOUNT_NAME
```

### Running

Run `ansible-test integration`. Currently some tests are disabled as [test are being verified and added](https://github.com/ansible-collections/google.cloud/issues/499).

## Role tests

### Prequisites for role tests

If you would like to use podman, you must
install the `molecule[podman]` package in PyPI:

```
pip install --upgrade molecule[podman]
```

### Running role tests

Ansible roles are tested via molecule.

```sh
module debug --test -s ${ROLE}
```

Role is the name of the role (e.g. gcloud, gcsfuse).

Add `-d podman` if you would like to use the podman driver.

If the linting fails, that is generally due to `ansible-lint`, which can be run directly:

```
ansible-lint
```

## Specific Tasks

The following enumerates detailed documentation for specific tasks related tot
the codebase.

### Updating the supported ansible-core version

1. modify the [ansible-integration-tests.yaml](.github/workflows/ansible-integration-tests.yml) to the version of ansible-core that you would like to test against.
1. (optional) update the version of ansible-core version required in [meta/runtime.yaml](meta/runtime.yml).
