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 in the Wiki or 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"
