How to run a reusable workflow conditionally?

Question

I have the following workflow in my GitHub actions:

name: Tests e2e iOS App

on:
  workflow_dispatch:
    inputs:
      skip:
        type: boolean
        required: true
        default: false

jobs:
  build-simu-ios-zip:
    name: Build iOS simulator zip
    uses: ./.github/workflows/reusable-e2e-buildsimuioszip.yml
    secrets: inherit
    with:
      environment: ${{ inputs.environment }}

I would like to run the job build-simu-ios-zip conditionally, I add the following:

jobs:
  build-simu-ios-zip:
    name: Build iOS simulator zip
+   if: ${{ inputs.skip == 'false' }}
    uses: ./.github/workflows/reusable-e2e-buildsimuioszip.yml
    secrets: inherit
    with:
      environment: ${{ inputs.environment }}

But the job automatically get skipped.

I also tried to pass an input to the reusable workflow and make it conditionally it from there, but it also skip.

How can I make a conditional reusable workflow in GitHub action?

Answer 1

I made some tests here and using if: ${{ inputs.skip == 'false' }} with single quotes ' doesn't work as you are comparing a boolean type with a string.

However, I found 2 options that worked:

• if: ${{ inputs.skip == false }} (no quote)

• if: ${{ ! inputs.skip }} (as it's a boolean input, but with !)

Note: I used this workflow for tests.
