Overview

The Forgejo project uses Playwright for testing its codebase. However, Playwright does not work on non-Debian-based Linux distributions. The usual workaround is to spin up a VM, but this consumes many resources and slows down your machine.

I couldn’t find any Docker image that solves this problem. Although the solution is simple, no one seems to have addressed it yet. So, I created a Docker image based on the official Playwright image specifically for testing Forgejo.

I created a Docker image based on Playwright’s official image with all prerequisites installed, so we can mount the project directory at runtime to run Forgejo test cases without copying the project into the image.

Playwright Setup

Checkout the official README.md written for e2e testing.

1. Pull the Docker Image:

docker pull iamyaash8/playwright-forgejo:v1.54.2.1-noble

2. Change directory into the Forgejo project and run the container in interactive mode:

cd forgejo/

docker run -it --rm -v .:/home/forgejo-tester iamyaash8/playwright-forgejo:v1.54.2.1-noble

Inside the Container

Make sure to clean frontend build, before running any tests and install playwright:

make clean frontend && npx playwright install-deps

Interactive Testing (recommended):

Ensure you completed the above mentioned setup

make test-e2e-debugserver

This command runs a forgejo instance locally, which already comes with dummy data to run tests on it. Playwright will be running tests on the local Forgejo instance that is currently running.

In case you see this error:

sed -e 's|{{REPO_TEST_DIR}}||g' \
        -e 's|{{TEST_LOGGER}}|test,file|g' \
        -e 's|{{TEST_TYPE}}|e2e|g' \
                tests/sqlite.ini.tmpl > tests/sqlite.ini
GITEA_ROOT="/home/iamyaash/Projects/codeberg/forgejo" GITEA_CONF=tests/sqlite.ini ./e2e.sqlite.test -test.run TestDebugserver -test.timeout 24h
Could not find gitea binary at /home/iamyaash/Projects/codeberg/forgejo/gitea
make: *** [Makefile:697: test-e2e-debugserver] Error 1

It’s looking for a binary named gitea, which would have been built during the previously required build step. However, you can skip that step by using this workaround:

touch gitea && sudo chmod 744 gitea

Running Test

• You can run the “full test suite”:

  make test-e2e-sqlite
  

  make test-e2e-mysql # when using mySQL database
  

  make test-e2e-pgsql # when using PostgreSQL database
  

• You can run individual tests:

  npx playwright test tests/e2e/pr-review.test.e2e.ts
  npx playwright test tests/e2e/* # run e2e tests only
  # it's flexible to use it the way you want
