With , you can test Scala, Scala.js (JavaScript), Scala Native, Dotty (Scala 3), and Java code . By offering deep integration with tools such as JUnit, TestNG, Ant, Maven, sbt, ScalaCheck, JMock, EasyMock, Mockito, ScalaMock, Selenium, Eclipse, NetBeans, and IntelliJ, makes it easy to take your testing to a higher, more productive level in new or existing Scala, Scala.js, or Java projects. Like the Scala language on which it is built, is designed to grow with the demands of its users : You can easily extend and compose 's core components to address just about any special requirements you may have. As a result, can scale to projects of all sizes, from an individual exploring a new idea to large teams collaborating on mission-critical software. One way scales down is that despite its rich feature set, is easy to get into .

To maximize your productivity, uses its own extension points to support several styles of testing out of the box. You can select whatever style best fits your team's experience and culture. For instance, the above example uses FlatSpec , a good choice for teams wishing to move from XUnit to BDD. When you run it, you get an informal specification of the software being tested: $ scala -cp scalatest_2.13-3.2.2.jar org.scalatest.run ExampleSpec Discovery starting. Discovery completed in 21 milliseconds. Run starting. Expected test count is: 2 ExampleSpec: A Stack - should pop values in last-in-first-out order - should throw NoSuchElementException if an empty stack is popped Run completed in 76 milliseconds. Total number of tests run: 2 Suites: completed 1, aborted 0 Tests: succeeded 2, failed 0, canceled 0, ignored 0, pending 0 All tests passed. does not try to impose a testing philosophy on you, but rather is designed from the philosophy that the tool should get out of your way and let you work the way you find most productive . If FlatSpec doesn't meet your team's needs, that's not a problem. has several other styles to choose from.
