Testing using Spock

Spock provides highly expressive specification language, DSL. Key Selling points for using spock:

• Data Driven Testing.

• Interaction Based Testing.

• Compatible with most IDEs, build tools and continuous integration servers.

• Has Web Console that allows you to instantly view, edit, run, and even publish Spock specifications.

• Compatible with Java and Groovy language interchangeability.

• what is wrong with junit

  • Ridiculous/Unreadable way of naming the test method. (Although junit5 has @Display(“for plain english title”))
  • Intent of the test is not clear, all those Java verbosity and mocking frameworks make you exhausted and ready to give up.
  • Junit/unit testing and Java, not the match made in heaven when It comes of BDD style testing.
  • Parameterized testing to do Data Driven Testing is not simple with Junit
