In this short tutorial, we'll show the benefits of combining the supporting power of Spring Boot 's testing framework and the expressiveness of the Spock framework whether that be for unit or integration tests. In a typical shop, you will see developers using JUnit or TestNG while the QA Team uses anything from HP's QTP (please, no!) Example, An assertion in JUnit would have looked as shown below: As you can see from the above, the Spock tests make the tests look less verbose as well as avoid all boilerplate code in assertions (and setup, etc.). This guide for software architects builds upon legacies of best practice, explaining key areas and how to make architectural designs successful. That way, data definition and final asserts are separated from the code under test, which is typically a function or a method call. given, when and then. This example introduces powerful expect-where combo! The following code sample demonstrates the structure of a Spock specification class: import org.junit.experimental.categories.Category import spock.lang.Specification @Category(UnitTest.class) class ExampleSpec extends Specification { //Constants //Fields //Fixture methods //Feature methods //Helper methods } The main change in Spock 2.0 M1 is migration to JUnit 5 (precisely speaking to execute tests with JUnit Platform 1.5, part of JUnit 5 instead of the JUnit 4 runner API). If a test fixture fails, Spock will give you a nicely formatted visual representation of what went wrong in the console output. 6. We also looked to verify API response status and response body, pass HTTP headers, and request path parameters as well. Write focused unit tests with flexible built-in mock objects. The test is annotated with the Integration annotation to indicate it is an integration test and extends the GebSpec super class: Spock example specifications along with ready-to-go Gradle and Maven builds. This is what the reports look like in version 1.3.0 and 1.3.1. If for some reason you don't like Spock, you may use standard jUnit style. If you're a single developer or your application is fairly small and self-contained (for example, a standalone utility), then the previous chapters have covered the most important Spock .
