Hands-On Microservices with Kotlin

Testing our services expressively

Now, that we have Kluent, let's modify our tests. First, we will work on CustomerServiceTest.

@Testfun `we should get a customer with a valid id`() {  val customer = customerService.getCustomer(1)  assertNotNull(customer)  assertEquals(customer?.name, "Kotlin")}

We can change our assertNotNull assertion to use shouldNoteNull, a high-level function that we can use in an object:
