Scalatest or specs2 with multiple test cases

Question

In TestNg and Java, we can run multiple test cases using DataProvider, and this runs as separate tests, meaning execution of a test isn't stopped on failure. Is there an analogue for ScalaTest or Specs/Specs2?

Answer 1

In both ScalaTest and specs2, it is easy to create test cases at run-time, in order to parameterize them with data. Here's an example with specs2:

   class BasketSpecification extends Specification {

     "a basket must contain fruits" >> {
       Seq(apple, banana, orange) foreach { fruit => 
         ("it contains: " + fruit) >> {
           basket must contain(fruit)
         }
       }
     }
   }

Then the output is:

 A basket must contain fruits
 + it contains: apple
 + it contains: banana
 + it contains: orange

Whereas the following specification:

   class BasketSpecification extends Specification {

     "a basket must contain fruits" >> {
       Seq(apple, cake, orange) foreach { fruit => 
         ("it contains: " + fruit) >> {
           basket must contain(fruit)
         }
       }
     }
   }

Will print out something like:

 A basket must contain fruits
 + it contains: apple
 x it contains: cake
   'basket' does not contain 'cake'
 + it contains: orange
