Define own assertions

Starting with Kluent 1.32, a generic should method was added to build domain specific assertions.

When the receiver function passed to should returns false or throws an exception, it will fail with an optional failure message.

Example

data class Person(val name: String, val surname: String)

fun Person.shouldHaveUppercaseName() = this.should("The name of $this should be uppercase") {
    name[0].isUpperCase()
}


Person("Pan", "Peter").shouldHaveUppercaseName()
