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

That concept is called "shared tests" in ScalaTest, because the same test code is being "shared" by multiple fixtures, where "fixtures" are the "data" in TestNG's DataProvider approach. There's a way to do this for each style trait in ScalaTest that expresses tests as functions. Here's an example for WordSpec:

http://www.scalatest.org/scaladoc-1.6.1/#org.scalatest.WordSpec@SharedTests

You can alternatively just use a for loop to register the same test code for different data points. This came up in an email discussion that's here:

http://groups.google.com/group/scalatest-users/browse_thread/thread/7337628407b48064#

The for loop code in that case looked like:

  for (browser <- List("IE", "Chrome", "Firefox")) { 
    test(browser + ": test one") { driver => 
      info("Testing using " + driver) 
    } 
    test(browser + ": test two") { driver => 
      info("Testing using " + driver) 
    } 
    test(browser + ": test three") { driver => 
      info("Testing using " + driver) 
    } 
    test(browser + ": test four") { driver => 
      info("Testing using " + driver) 
    } 
    test(browser + ": test five") { driver => 
      info("Testing using " + driver) 
    } 
  } 
} 

This actually registers 15 tests, five tests for each browser driver. This I believe is what you're after.
