Kluent
Kluent is a "Fluent Assertions" library written specifically for Kotlin.
It uses the Infix-Notations and Extension Functions of Kotlin to provide a fluent wrapper around the JUnit-Asserts and Mockito.

Examples
More examples can be seen on the Site or in the tests.
assertEquals
"hello" shouldEqual "hello"
assertNotEquals
"hello" shouldNotEqual "world"
Assert that an Array/Iterable contains something
val alice = Person("Alice", "Bob")
val jon = Person("Jon", "Doe")
val list = listOf(alice, jon)
list shouldContain jon
Stubbing
val stub = mock(Database::class)
val bob = Person("Bob", "Guy")
When calling stub.getPerson() itReturns bob
Using backticks
Every method that is included in Kluent also has a "backtick version", to make it feel more like a describing sentence.
Some examples:
assertEquals
"hello" `should equal` "hello"
assertNotEquals
"hello" `should not equal` "world"
