If you have:
infix fun <T> T?.shouldBe(expected: T?) = assertEquals(expected, this)
you can write the following DSL-like code in your tests:
@Test
fun test() {
100.plusOne() shouldBe 101
}
If you have:
class MyExample(val i: Int) {
operator fun <R> invoke(block: MyExample.() -> R) = block()
fun Int.bigger() = this > i
}
you can write the following DSL-like code in your production code:
fun main2(args: Array<String>) {
val ex = MyExample(233)
ex ...
If you have:
val r = Random(233)
infix inline operator fun Int.rem(block: () -> Unit) {
if (r.nextInt(100) < this) block()
}
You can write the following DSL-like code:
20 % { println("The possibility you see this message is 20%") }
If you have:
operator fun <R> String.invoke(block: () -> R) = {
try { block.invoke() }
catch (e: AssertException) { System.err.println("$this\n${e.message}") }
}
You can write the following DSL-like code:
"it should return 2" {
parse("1 + 1").bu...
