OLD Material to Consider

Let's add existing stuff (like JUnit 4 extensions) that might be valuable input for JUnit Lambda...

External Material

• Quo Vadis JUnit
  • Started by an open-space session during XP-Days Germany in October 2014
• LambdaSpec: RSpec like testing with Java lambdas.
  • Article on the topic
• Jumi: Parallel test execution by default. Backwards compatible to JUnit.
• Hierarchical Context Runner: Runner for JUnit by Stefan Bechtold.
  • Hierarchical testing with @Context: Also from Stefan.
• Exception testing with Lambdas - 1
• Exception testing with Lambdas - 2
• Combining matchers, streams and lambdas
• JUnit Java8 Runner: Allowing test methods in interfaces.
• JUnit Quickcheck: A quickcheck reimplementation in Java building on JUnit theories
• Better Category Support: Category support in JUnit 4.x lags behind NUnit. Specifically the need to use @SuiteClasses() puts categories back in the world of JUnit 3 where we had to predefine the suite before run time. - Mark Levison @mlevison
• Parameterization
  • junit-dataprovider
  • junitparams
  • lambda-parameterized: Proof of concept for type safe parameterized JUnit 4 tests with the help of lambda expressions.
  • Parameterized Tests based on JUnit Rules The reason why I think this is interesting, because it proves that you don't need any special test discovery mechanism to support parameterized tests. No annotations, no special add on, just a rule.
• A little repository where I play around with my ideas, how JUnit Lambda might look like: https://github.com/schauder/junit5-spike
• Tumbler-Glass, a metadata injection and reporting tool - mlschechter
• Some Java8 experiments
• Lambda-Behave: A test framework for Java 8 based on lambdas.
• lambspec, an RSpec-like assertion library for Java >= 8.

Early proposals from JUnit team

###Proposal 1 : Using initialization blocks and lambdas to define tests

• Examples

###Proposal 2 : Using different kinds of decorators, categories and other ideas

• Examples
