How to pass user input into jenkins function invocation?

Question

I have this jenkins stage:

    stage('Run tests?') {
        agent none
        steps {
          script {
            TESTS = input message: 'User input required', parameters: [
              choice(name: 'Run Tests', choices: 'yes\nno', description: 'Run unit and e2e tests?')]
          }
        }
    }

and below I do this:

  stage('test-unit') {
            when {
                expression {
                    return shouldRunTests('yes')
                }
            }

however, I'm wondering how to pass the user input of either yes or no into the function? so far, it's always running the tests regardless of whether I say yes or no. I know above I have hardcoded ('yes') that's because I saw an example do it like that. anyone care to help me how I can pass this in?

my shouldRunTests function just returns true or false based on the parameter passed in

You can create "TESTS" variable before the pipeline block starts and use it in any stage, as done in this example.
