Quick Start

Follow the installation instructions and create the following specification in a file named HelloWorldSpec.scala:

class HelloWorldSpec extends Specification { def is = s2"""

 This is a specification to check the 'Hello world' string

 The 'Hello world' string should
   contain 11 characters                                         $e1
   start with 'Hello'                                            $e2
   end with 'world'                                              $e3
                                                                 """

  def e1 = "Hello world" must have size(11)
  def e2 = "Hello world" must startWith("Hello")
  def e3 = "Hello world" must endWith("world")
}

A specs2 software specification is nothing more than a Scala class extending org.specs2.Specification and declaring a special is method. This method contains both plain text describing what the application should do but also some method calls containing a more formal specification of the expected behaviour.

Execution

And this is it! Now you can execute your specification with a runner and observe the results:

> scala -cp ... specs2.run HelloWorldSpec

HelloWorldSpec

This is a specification to check the 'Hello world' string

The 'Hello world' string should
  + contain 11 characters
  + start with 'Hello'
  + end with 'world'
