This user guide will help you get rolling quickly with Scalactic. First a brief orientation:

• Scalactic, which emerged from the ScalaTest 2.0 project, focuses on aspects of testing that can also be useful in production code.
• The org.scalactic package is included in the ScalaTest's jar, but is also available separately in a small Scalactic jar.
• Scalactic is released alongside ScalaTest, with version numbers that match exactly. When ScalaTest 2.1 is released, for example, Scalactic 2.1 will also be released.
• You can use Scalactic in your production code and tests no matter what test framework you use.
