Quick hack of a readable DSL for writing assertions in Kotlin

TEST_DSL.kt

import kotlin.test.assertEquals

fun <T> equal(expected: T) : (T) -> Unit {
  return { t ->
    assertEquals(t, expected);
  }
}

infix fun <T> T.should(matcher: (T) -> Unit) {
  matcher(this);
}

// in test
"FOO" should equal("5");
