| # Camel Google Functions Component |
| This component is based on the [google java functions library](https://github.com/googleapis/java-functions) that works as a client for the Google Cloud Functions. |
| |
| |
| ## Camel Google Storage Functions testing |
| |
| The unit tests provided are somewhat limited. |
| Due to the nature of the component, it needs to be tested against a google Functions instance because although there are some emulators |
| they doesn't cover all the functionalities. |
| |
| The tests are organized into two packages: |
| * **Unit** : Standalone tests that can be conducted on their own |
| * **Integration** : Tests against a Google Functions instance |
| |
| ### Execution of integration tests |
| |
| To run the Google Functions client library, you must first set up authentication by creating a service account key. |
| You can find more info at: [Google Cloud Authentication](https://github.com/googleapis/google-cloud-java#authentication). |
| |
| When you have the **service account key** you can provide authentication credentials to your application code by setting the environment variable: |
| |
| `export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/my-key.json"` |
| |
| or for windows: |
| |
| `$Env:GOOGLE_APPLICATION_CREDENTIALS = "/home/user/Downloads/my-key.json"` |
| |
| or directly through the component endpoint |
| |
| `from("google-functions://myCamelFunction?serviceAccountKey=/home/user/Downloads/my-key.json")` |
| |
| |
| Running tests against Google Functions instance: |
| |
| ``` |
| mvn verify |
| ``` |
| |
