Step 3) Lets analyse expected output step by step: Consider all assert statements one by one: Now compare string1=" Junit" with string2=" Junit" with equals method of object class. Replacing assertEquals method from java.lang.Object.equals () method : So assertEquals (string1,string2) will return true.

Lets say you have simple class that is using the Scala assert method: class Example { def test = { assert( (1+1) == 2, "Addition broken") } } When you enable the jvmassert compiler plugin, it will translate the previous example to:

The specs testing framework, an open source tool written in Scala by Eric Torreborre, also supports the BDD style of testing but with a different At the end of each test you should call assert to test that a condition has been satisfied; Using ScalaTest like this is similar to JUnit, so if you’re coming to Scala from Java, hopefully this looks very familiar. Now you can run these tests with the sbt test command. Skipping the first few lines of output, the result looks like this: Selecting testing styles for your project.

Update: Scala 2.8 has an annotation called elidable that will (when 2.8 is complete) allow one to remove method calls at compile time by setting a compiler flag. The assert, etc methods are all marked with this flag and as a result can be removed at compile time for production environments.
