The given, on, and it blocks

This style assumes the use of the following DSL blocks:

• given: This block defines the context of our test. It can be a class that we want to test.
• on: This block defines the function or action that we want to test.
• it: This block defines an actual test. It can be the input or output of a function.

@RunWith(JUnitPlatform::class)object ToDoSpek : Spek({    given("A storage") {        val storage = ToDoStorage()        on("set a todo with with args: name and context") {            val todo = ToDo("name", "content")            val result = storage.set("name", todo)            it("returns true") {                assert(result)            }        }    }})
