How to run git actions conditionally based on folder match - github

Question

I have this git action setup where I want to run regression only on folder1 and not folder2.
name: Node.js CI
on:
push:
branches: [ develop ]
jobs:
build:
runs-on: ubuntu-latest
strategy:
matrix:
node-version: [14.x]
dir: ['./folder1', 'folder2']
steps:
- uses: actions/checkout#v2
- name: Use Node.js ${{ matrix.node-version }}
uses: actions/setup-node#v2
with:
node-version: ${{ matrix.node-version }}
- name: Install Dependencies
run: npm ci
- name: Run regression tests
run: npm run regression
How can we achieve this?

Answer 1

You can use if conditions to do this.
name: Node.js CI
on:
push:
branches: [ develop ]
pull_request:
branches: [ develop ]
jobs:
build:
runs-on: ubuntu-latest
strategy:
matrix:
node-version: [12.x]
dir: ['./folder1', 'folder2']
steps:
- uses: actions/checkout#v2
- name: Use Node.js ${{ matrix.node-version }}
uses: actions/setup-node#v2
with:
node-version: ${{ matrix.node-version }}
- name: Install Dependencies
run: npm ci
run: npm run lint
- name: Run unit
run: npm run test:unit
working-directory: ${{ matrix.dir }}
- name: Run integration
if: ${{ matrix.dir == './folder1' }}
run: npm run test:integration
working-directory: ${{ matrix.dir }}
