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"
