Contributing to AL-Go

This section describes how to contribute to AL-Go. How to set up your own environment (your own set of actions and your own templates)

You can do this in two ways:

  • Use a fork of AL-Go for GitHub in your own personal GitHub account in development mode
  • Use 3 public repositories in your own personal GitHub account (AL-Go-PTE, AL-Go-AppSource and AL-Go-Actions, much like in production)

Use a fork of AL-Go for GitHub in "development mode"

  1. Fork the https://github.com/microsoft/AL-Go repository to your personal GitHub account.
  2. You can optionally also create a branch in the AL-Go fork for the feature you are working on.

https://github.com//AL-Go@ can now be used as a template in your AL-Go project when running Update AL-Go System Files to use the actions/workflows from this fork.

Use 3 public repositories in "production mode"

  1. Fork the https://github.com/microsoft/AL-Go repository to your personal GitHub account.
  2. Navigate to https://github.com/settings/tokens/new and create a new personal access token with Full control of private repositories and workflow permissions.
  3. In your personal fork of AL-Go, create a New Repository Secret called OrgPAT with your personal access token as content. See https://github.com/yourGitHubUserName/AL-Go/settings/secrets/actions.
  4. In your personal fork of AL-Go, navigate to Actions, select the Deploy workflow and choose Run Workflow.
  5. Using the default settings press Run workflow. Select the AL-Go branch to run from and the branch to deploy to.

Now you should have 3 new public repositories:

Note

Deploying to a branch called preview will only update the two template repositories (and use your AL-Go project with the current SHA as actions repository).

You can optionally also create a branch in the AL-Go fork for the feature you are working on and then select that branch when running Deploy (both as Use workflow from and as Branch to deploy to).

yourGitHubUserName/AL-Go-PTE@yourBranch or yourGitHubUserName/AL-Go-AppSource@yourBranch can now be used in your AL project when running Update AL-Go System Files to use the actions/workflows from this area for your AL project.

Please ensure that all unit tests run and create a Pull Request against https://github.com/microsoft/AL-Go. You are very welcome to run the end to end tests as well, but we will also run the end to end tests as part of the code review process.

Note

You can also deploy to a different branch in the 3 public repositories by specifying a branch name under Branch to deploy to when running the Deploy workflow. The branch you specify in Use workflow from indicates which branch in your personal fork of the AL-Go repository you publish to the 3 repositories.

Pre-Commit

In the AL-Go repository we use a number of precommit hooks to help us identify issues in the code. We run the precommit hooks locally but also as a PR check. In order to ensure this check passes please install pre-commit in your local AL-Go repository. Pre-Commit can be installed by following the instructions on https://pre-commit.com/#quick-start. Once the precommint hooks are installed you can run pre-commit run --all-files to verify your changes.

Unit tests

The Tests folder, in the AL-Go repository, contains a number of unit-tests. Open Tests/runtests.ps1 in VS Code and select Run. Unit tests are quick and will run on every PR and every Push. We will be adding a lot of unit tests going forward.

End to End tests

In the e2eTests folder, in the AL-Go repository, there are 3 types of end to end tests.

  • Test-AL-Go.ps1 contains an end-2-end test scenario and is in E2E.yaml run for all combinations of Public/Private, Windows/Linux, Single/Multiproject and PTE/AppSource.
  • Test-AL-Go-Upgrade.ps1 contains an end-2-end upgrade scenario and is run for all prior releases of AL-Go for GitHub to test that you can successfully upgrade that version to the latestand run CI/CD successfully.
  • The scenarios folder contains a set of AL-Go scenarios, which tests specific functionality end to end. Every folder under e2eTests/scenarios, which contains a runtests.ps1 will be run as a scenario test, like:
    • UseProjectDependencies - create a repo with multiple projects and set UseProjectDependencies to modify CI/CD and other build workflows to build projects in the right order
    • GitHubPackages - create 3 repositories using GitHub Packages as dependency resolver and check that artifacts are built properly
    • BuildModes - create a repository, set buildModes and test that generated artifacts are as expected.
    • ReleaseBranches - testing that create release works, release branches are create and subsequently found correctly as previous build
    • SpecialCharacters - testing that various settings (+ publisher name and app name) can contain special national characters

In your personal fork, you can now run the end to end tests, if the following pre-requisites are available:

  • You need the following secrets:
    • E2EPAT needs to be a Personal Access Token with these permissions: admin:org, delete:packages, delete_repo, repo, workflow, write:packages
    • AdminCenterApiCredentials needs to be the adminCenterApiCredentials as described here.
    • LicenseFileUrl needs to be a direct download URL to a developer .bclicense file
  • Beside the secrets, you need to have a GitHub organization setup, which will contain all the temporary repositories created by the end to end testing. This organization needs to have at least two instances of a GitHub runner registered as self-hosted (for running all private repo builds)

Run the End to end tests by running the End to end tests workflow and specify your organization in the corresponding field. End to end testing will create a lot of repositories called tmpXYZ, where XYZ is a random letter combination. If End to end tests are failing, the tmp repositories are NOT removed, but can be used for troubleshooting. You can run the Cleanup after failed E2E workflow to cleanup these repositories.

You can also run the end to end tests directly from VS Code, by providing the following global variables:

Variable Type Description
$global:E2EgitHubOwner String The GitHub owner of the test repositories (like freddydk or microsoft)
$global:SecureE2EPAT SecureString A personal access token with workflow permissions
$global:SecureAdminCenterApiToken SecureString Admin Center API Credentials
$global:SecureLicenseFileUrl SecureString Direct download URL to a license file
$global:pteTemplate String URL for your PTE template (like freddyk/AL-Go-PTE@main or freddydk/AL-Go@main|Templates/Per Tenant Extension for using your AL-Go fork directly)
$global:appSourceTemplate String URL for your PTE template (like freddyk/AL-Go-AppSource@main or freddydk/AL-Go@main|Templates/AppSource App for using your AL-Go fork directly)
