An example of a clear test for a system which recommends the most appropriate jobs based on machine learning models

ClearUnitTest

// A test with relevant details right in the test itself
@Test
fun `get ML recommended jobs with new user expect predefined list`() {
  // Test arrangements and setup
  
  val engine = getRecommendationEngine()
  val jobs = engine.getJobs(new User(UserStatus.FAIRLY_NEW, "testId", "Test User Name"))
  assertThat(jobs).isEqualTo(expectedJobs) 
}

// A test with relevant details abstracted out
@Test
fun `get ML recommended jobs with new user expect predefined list`() {
  // Test arrangements and setup
  
  val engine = new RecommendationEngine(getEnvDetails(), getLocalInfo(), getSessionProperties())
  val jobs = engine.getJobs(getTestUserInfo())
  assertThat(jobs).isEqualTo(expectedJobs)
