Spock is a BDD-style testing framework for Java and Groovy applications that integrates unit testing, mocking, and business-driven development in one package. It features a highly expressive specification language, compatibility with major IDEs and build tools, and facilitates easy data-driven testing. This framework simplifies the testing process without the need for additional libraries, offering a streamlined solution for developers.

4. What is Spock Framework?
● Spock is a BDD-style developer testing and specification framework for Java and
Groovy applications.
● Spock combines unit testing, mocking stubbing and business driven development
all into one framework so you don’t have to download/include additional libraries
in your build.
● Everything is inbuilt in Spock framework, it was inspired by JUnit framework only
and JUnit is also used under the hood.
● We will write the code in Java but we will test the code in Groovy.

5. Spock Features
● Highly expressive – Test cases can be expressed in terms of given, when and then
blocks.
● Compatible with most IDEs – It is compatible with all the leading IDEs in the
market.
● Compatible with build tools – Compatible with Maven as well as Gradle.
● Compatible with Continuous integration servers – The JUnit runner makes it
compatible with all the continuous integration servers out there.

6. Why Spock Framework?
● Highly Expressive Specification Language.
● Compatibility with leading IDEs.
● Test cases are written in Groovy which is pretty much similar to Java and also a
JVM based language.
● One framework for all types of test cases, no other libraries are required to write
test cases.
● Expressive than the typical Junit.
● Easy data driven testing which was very verbose in Junit

7. What is Specification?
● A specification is represented as a Groovy class that extends from
spock.lang.Specification.
● The name of a specification usually relates to the system or system operation
described by the specification.
● Class Specification contains a number of useful methods for writing specifications.
Furthermore it instructs JUnit to run specification with Sputnik, Spock’s JUnit runner.
● Thanks to Sputnik, Spock specifications can be run by most modern Java IDEs and
build tools.
