How to run a specific test or class using jenkins pipeline

Question

I'm using this command to run my tests:

sh "${mvnHome}/bin/mvn clean test -e -Dgroups=categories.dbd"

but sometimes I want to run a specific test. How can I do it?

I read that I can use "This project is parameterized" but didn't understand how to use it.

I also saw this - https://plugins.jenkins.io/selected-tests-executor/ but it's not good enough since it required an external file.

If you use the maven-surefire-plugin you can simply run

sh "${mvnHome}/bin/mvn clean test -e -Dgroups=categories.dbd -Dtest=com.example.MyJavaTestClass"

or

sh "${mvnHome}/bin/mvn clean test -e -Dgroups=categories.dbd -Dtest=com.example.MyJavaTestClass#myTestMethod"

I suggest to add a parameter for the test class/method to your pipeline definition.

pipeline {

  agent any

  parameters {
    string defaultValue: '', description: 'Test Name', name: 'TEST_NAME', trim: false
  }

  stages {
    stage('run tests') {
      steps {
        script {
          def optionalParameters = ""
          if (params.TEST_NAME != null) {
            optionalParameters += " -Dtest=" + params.TEST_NAME
          }
          sh "${mvnHome}/bin/mvn clean test -e -Dgroups=categories.dbd" + optionalParameters
        }
      }
    }
    ...
  }
  ...
}
