Kanbanbot

A bot to automatize some repetitive actions on PR's and PR Dashboard

Requirements and application running

Only php (see the version here) and a server like apache are needed.

1. Run composer install
2. Setup a webserver to serve the root directory of the application. For example use Symfony built-in server with command symfony serve

You can also use Docker.

Functioning

Kanbanbot is mainly based on one webhook. See the following code here :

webhook:
        routing:
            github:
                service: App\Shared\Infrastructure\Webhook\GithubWebhookParser

The production application has been setup so that GitHub send every event that happens on PrestaShop organization to Kanbanbot as webhook.

Kanbanbot listens to received events and then run the appropriate commands.

How to add a usecase ?

There are two layers to consider when adding a new usecase :

1. The first layout is responsible to match the appropriate commands in terms of the triggered event. To do that you have to create a new class which implements App\Shared\Infrastructure\Factory\CommandFactory\CommandStrategyInterface.php. You can see some examples in the src/Shared/Infrastructure/Factory/CommandFactory/Strategy/Command folder. In this layer you can also add global github event exclusions. To do that you can create a new class which implements App\Shared\Infrastructure\Factory\CommandFactory\ExclusionStrategyInterface.php. You can see some examples in the src/Shared/Infrastructure/Factory/CommandFactory/Strategy/Exclusion folder.
2. The second layout contains the commands themselves. They are dispatched in several Bounded context like in PullRequest and in PullRequestDashboard.

Testing

The whole application is tested. This widely avoids regressions and allows easy refactoring or library updating.

There are three kinds of tests:

1. Unit tests. In this application unit test means that no infrastructure (like db, api calls ...) are used. This allows a really fast execution and then it gives a quick feedback to practice TDD. Also unit tests adopts a functional approach. It means that it tests the behavior of the application and not the implementation. Concretely they test CommandHandler. Here is an example
2. Integration tests. They test only adapters like implementations of repositories. Here is an example
3. EndToEnd tests. They test that commands are well dispatched in terms of the request. Here is an example

Composer scripts

There are some composer scripts to help you to develop (unit tests, integration tests, end to end tests, code style, phpstan ...). Before pushing a commit you can run composer local-ci to check if everything is ok.

Deployment of kanbanbot new version

1. Bump the version number in app.version variable in the config/service.php file!
2. Follow the GitHub workflow described below to deploy latest version of main branch

You can verify the deployed version : ping the /healthcheck route that will return the version number.

Environments

• Production: kanbanbot.prestashop-project.org

Workflow

The GitHub workflow is used as follow:

As you can see from the schema above

• add the label "integration-deployment" to a Pull Request to trigger the deployment of the integration environment and be able to test it
• merge a Pull Request against branch main to trigger the deployment of the preprod environment and be able to test it
• publish a GitHub release to trigger the deployment of the production environment
