Is it possible to drigger different task for different changed files?

[Andrey Tsarenko]

For example.

My repo contains a three folders: "project1" "project2" and "core".

When I change a files under "core" folder I want trigger "npm run test Project1" and "npm run test project2".

If I changed the "project1" files I want test only "project 1".
If I changed the "poject2" - I want test only "project2".

I don't want to separate this folders on separate repositories, or use git submodules and subthrees. And also I don't want to every time test everything.

I heard that in teamcity such task is called triggers.

Does the "bitbucket pipeline" support this a kind of feature?

Hi Andrey,

I can't think of an easy way to achieve exactly what you're after in Pipelines. However have you considered running the tests for each project in separate parallel steps?

https://confluence.atlassian.com/bitbucket/parallel-steps-946606807.html

This would allow your pipeline to complete faster than running all the tests in a single step.

Obviously there are also disadvantages to this approach (primarily that you will use more build minutes relative to running just one set of tests at a time).

Otherwise it may be possible to write a custom script to do what you want using git commands, depending on your workflow. For instance if your workflow involves always squashing your commits into a single commit before pushing then you could use git commands to work out which projects are affected by the last commit. For instance the following commands output the number 1 if the corresponding project is affected by the last commit and 0 otherwise:

git diff-tree --no-commit-id --name-only HEAD core | wc -l
git diff-tree --no-commit-id --name-only HEAD project1 | wc -l
git diff-tree --no-commit-id --name-only HEAD project2 | wc -l

Cheers,
