Create and synchronize a PR in a dependent repository

# Hacking
|
|
|
|
The test environment consists of the following (all users password is admin1234)
|
|
|
|
* A forgejo instance with a runner
|
|
* An unprivileged user user1
|
|
* The repository user1/originrepo
|
|
* contains a pull_request workflow using cascading-pr that targets user2/destinationrepo
|
|
* contains a script that will modify user2/destinationrepo
|
|
* a branch1 at the same commit as main
|
|
* The repository user1/cascading-pr with the action under test
|
|
* An unprivileged user user2
|
|
* The repository user2/destinationrepo
|
|
|
|
The test for a successful run of the cascading-pr action consists of:
|
|
|
|
* creating a PR from branch1 to main
|
|
* wait for the commit status until it is successful
|
|
|
|
## testing an update on the action
|
|
|
|
* run `tests/run.sh --debug` once so all is in place
|
|
* commit changes to the files that are in the cascading-pr action
|
|
(action.yml, cascading-pr.sh etc.)
|
|
* push the modified action to `user1/cascading-pr`
|
|
* visit $url/user1/originrepo/actions/runs/1 and click re-run
|
|
|
|
## interactive debugging
|
|
|
|
Following the steps below recreate the same environment as the
|
|
integration workflow locally. It is helpful for forensic analysis when
|
|
something does not run as expected and the error displayed are unclear.
|
|
|
|
To help with the development loop all steps are idempotent and
|
|
running `tests/run.sh --debug` multiple times must succeed.
|
|
|
|
Individual steps can be run independendely by using the name of the function.
|
|
For instance:
|
|
|
|
* `tests/run.sh --debug create_pull_request` will only call the `create_pull_request`
|
|
function found in `tests/run.sh` to (re)create the pull request in `user1/originrepo`.
|
|
* `./cascading-pr.sh --debug --origin-url ... upsert_branch` will only call the `upsert_branch`
|
|
function found in `cascading-pr.sh`.
|
|
|
|
## directories
|
|
|
|
The `tests/run.sh` script stores all its files in
|
|
`/tmp/cascading-pr-test`. The temporary directories created by
|
|
`cascading-pr.sh` are disposed of when the script ends.
|
|
|
|
## logging
|
|
|
|
If `--debug` is used a full debug log is displayed, very complete and
|
|
very verbose. Otherwise it is stashed in a temporary file and only
|
|
displayed if an error happens.
|
