Code Examples

Welcome to Scala 2.12.8 (OpenJDK 64-Bit Server VM, Java 1.8.0_212).
Type in expressions for evaluation. Or try :help.

scala> import com.eed3si9n.expecty.Expecty.assert
import com.eed3si9n.expecty.Expecty.assert

scala> case class Person(name: String = "Fred", age: Int = 42) {
     |   def say(words: String*) = words.mkString(" ")
     | }
defined class Person

scala> val person = Person()
person: Person = Person(Fred,42)

scala> // Passing expectations

scala> assert(person.name == "Fred")

scala> assert(person.age * 2 == 84)

scala> assert(person.say("Hi", "from", "Expecty!") == "Hi from Expecty!")

scala> // Failing expectation

scala> val word1 = "ping"
word1: String = ping

scala> val word2 = "pong"
word2: String = pong

scala> assert(person.say(word1, word2) == "pong pong")
java.lang.AssertionError: assertion failed

assert(person.say(word1, word2) == "pong pong")
       |      |   |      |      |
       |      |   ping   pong   false
       |      ping pong
       Person(Fred,42)
