Azure pipeline using matrix environment variable in step condition

Question

In my Azure DevOps pipeline I have the following:

strategy:
  matrix:
    unit_test_linux:
      imageName: 'ubuntu-16.04'
      TYPE: 'unit'
    cucumber:
      imageName: 'ubuntu-16.04'
      TYPE: 'cucumber'

I want to use TYPE in a step condition, a bit like below, how do I do this?

- bash: |
    set -ev
    cd ./client
    npm install
  displayName: install
  env:
    DISPLAY: ':99.0'
  condition: and(succeeded(), eq(variables['Agent.OS'], 'Linux'), eq(${{'TYPE'}}, 'unit'))``

Answer 1

The matrix variable is like every variable, so in this way:

condition: and(succeeded(), eq(variables['Agent.OS'], 'Linux'), eq(variables['TYPE'], 'unit'))
