How to define a test run in github-actions in a specific branch for a python script?

Question

What I have so far is this code:

name: test run

on:
  push:
    branches:
        - V2.0

jobs:
  build:

    runs-on: [windows-2019]

    steps:
    - uses: actions/checkout@v2

    - name: Set up Python 3.8
      uses: actions/setup-python@v2
      with:
        python-version: 3.8

    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install pyautogui
        pip install opencv-python
        pip install numpy
        pip install pynput
       
    - name: Test
      run: python Cristishor201/[email protected]/src/pytest.py

And I want to run pytest.py script which is inside my_repo repository, branch V2.0, and in folder src. Does anyone have an idea how to do this ?

UPDATE 1:

I found this article when he put github.ref environment variable using if statement. The problem with this solution is that it skip the code, and I already filtered the branch in the trigger block.

name: my workflow
on: push
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - name: Execute tests
        run: exit 0
  deploy:
    runs-on: ubuntu-latest
    needs: test
    if: github.ref == 'refs/heads/master'
    steps:
      - name: Deploy app
        run: exit 0

I tried using env: instead if: but it didn't work.

Github action actions/checkout@v2 pulls the current branch for which this pipeline was triggered. Since you are specifically telling the pipeline to trigger on V2.0 then you don't need to specify a specific branch to checkout.

Now you are in the current working directory so you can just do the following to properly find your file in the path.

python .\src\pytest.py

Note: this assumes your repo directory structure contains src at the root level of your repo

src
└── pytest.py
