Testing pull requests

Many people are developing new features or fixing bugs on GitHub. To help with engine development, you may be asked to test those pull requests with a Godot build that includes code from the pull request in question.

Thanks to GitHub Actions, all pull requests have continuous builds available. These builds let you try out pull requests without having to compile anything from source.

Downloading a compiled build

You can download pull request builds from GitHub Actions. Since only signed in users may download builds directly from GitHub Actions, the procedure varies depending on whether you have a GitHub account or not.

備註

Due to a GitHub Actions limitation, builds are only available for 90 days after the pull request was last updated. If you still wish to try a pull request locally, you can compile the pull request branch from source instead.

If you have a GitHub account

  • Open the pull request page. Click the Checks tab near the top of the page:

  • In the list of platforms that appears on the left, select your platform by clicking it then choose the type of build you need (editor or export template). If in doubt, select an editor build:

  • Click the Artifacts dropdown on the right of the page then click the artifact's name to download it:

../../_images/testing_pull_requests_checks_artifacts.png
  • Extract the ZIP archive then run the executable. Note that Windows and macOS binaries are not code signed. This means you may have to bypass a security warning before you can run the executable. If you frequently test pull request builds, it may be better to disable Windows SmartScreen or disable macOS Gatekeeper permanently.

If you don't have a GitHub account

If you don't have a GitHub account and can't sign up for one, you can use the third-party nightly.link service to generate a universal download link.

  • Open the pull request page. Click the fork's branch name near the top of the page:

../../_images/testing_pull_requests_access_fork.png
  • Now that you are on the fork's branch page, click the .github folder at the top of the file list. Then, click on the workflows folder (whicb is inside the .github folder). Click the workflow file for the platform you wish to download artifacts for. After clicking on the file (which opens the file view), copy the page URL from your browser's address bar.

  • Open the nightly.link website and paste the URL you just copied into the text field located below the heading Paste a GitHub link, get a nightly.link!. After pasting the URL, click Get links on the right. If the the format of the URL you pasted is correct, you should be presented with a page like this:

../../_images/testing_pull_requests_nightly_link.png
  • Click the URL of the artifact you wish to download.

  • Extract the ZIP archive then run the executable. Note that Windows and macOS binaries are not code signed. This means you may have to bypass a security warning before you can run the executable. If you frequently test pull request builds, it may be better to disable Windows SmartScreen or disable macOS Gatekeeper permanently.

Compiling a pull request branch from source

This approach may be needed for pull requests that were last updated more than 90 days ago, or to test on platforms and configurations that are not supported by Godot's GitHub Actions setup.

  • Open the pull request page. Click the fork's branch name near the top of the page:

../../_images/testing_pull_requests_access_fork.png
  • Now that you are on the fork's branch page, click the green Code button on the right of the page then choose Download ZIP in the dropdown:

../../_images/testing_pull_requests_fork_zip.png
  • Extract the ZIP archive and follow the compiling instructions for your operating system.
