The example below shows a simple system that fetches jobs for a user who can be either registered or unregistered.

DescriptiveTestNameExample.kt

// Unit under test.
fun fetchJobs(user: User) : List<Job> {
 if (user.isRegistered()) {
 return emptyList()
 } else {
 val jobs = jobsApi.getJobs(user)
 return jobs
 }
}
// A test with a non-descriptive name.
@Test
fun `test fetch jobs`() {
     // Test arrangements and setup.
     val user = getRegisteredTestUser()
     val jobs = jobsSource.fetchJobs(user)
     assertThat(jobs).isEqualTo(expectedJobs)
}

// A test with a descriptive name.
@Test
fun `fetch jobs with registered user verify valid list returned`() {
     // Test arrangements and setup.
     val user = getRegisteredTestUser()
     val jobs = jobsSource.fetchJobs(user)
     assertThat(jobs).isEqualTo(expectedJobs)
}
