A small test creating an assertion/matcher with infix functions. Easily extendable using extension functions.
Origin of a test is the object itsef. The object must satisfy criteria
@Test
fun `usage test`() {
12 mustSatisfy {
}
}Various criteria can be described depending on the class type:
@Test
fun `usage test`() {
12 mustSatisfy {
it isGreaterThan 6
}
}Nullability can be checked using additional adjectives:
@Test
fun `usage test`() {
val obj: String? = null
obj mustSatisfy {
it mustNotBe Null
}
}Checking a parameter of a more complex object can be achieved using a nested mustSatisfy block:
@Test
fun `usage test`() {
val obj = MyObj(12, "", emptyList())
obj mustSatisfy {
it mustNotBe Null
it mustBeOfType MyObj::class
it.content.number mustSatisfy { number ->
number mustBeEqualTo 12
}
}
}
data class MyObj(
val number: Int,
val anyObj: Any,
val list: List<String>
)
