How can I create PR Validation Trigger in bitbucket pipelines?

Trigger options I have looked at are:

- `branches` will run automatically on a commit to a branch

- `pull-requests` in my testing will run when a pull request is created or merged


I would like a trigger that runs on each commit to a branch that is currently part of a pull request.


I am considering using the branches trigger for all branches and writing a custom pipe to check the Bitbucket API to get any related PRs for the commit. The downside being that it would require a pipeline run for every commit to any branch and I am not sure what I would do in the case no PR was found. I guess in that instance I could fail the build but that is not an ideal outcome to have a bunch of failed builds in my pipeline history.

Hello @Wayne Pichotta ,

Welcome to Atlassian Community!

When you use the pull-requests trigger, it will trigger the pipeline in the Pull-Request creation, as well as in every push to the source branch of the pull request.

Let's take the below YML file as an example:


'**': #this runs as default for any branch not elsewhere defined
- step:
- echo "Runs for any branch not defined below"
feature/*: #any branch with a feature prefix
- step:
- echo "Runs for any branch that starts with feature"

Supposing that I have created a branch called feature/1 from master. When I create a Pull Request from feature/1 to master, the pull request pipeline feature/* will be triggered. While the Pull request is open, every subsequent commit to the source branch of the PR (in this case feature/1) will also trigger the pipeline  feature/*

You can use something similar to the above in your yml to get the pipeline to trigger in every commit to a branch that is the source of a pull request.

Hope that helps! Let me know in case you have any questions.

Thank you, @Wayne Pichotta .

Kind regards,

Patrik S

@Patrik S wow that is embarrassing. It does exactly what I was asking for. I thought it was not acting that way in my testing last week. Thanks for your patience and taking the time to answer. This is great.
