Using the Gherkin syntax is Given not a synonym for beforeGroup / beforeEachTest? It seems like that would make sense. For example it’s where I’d want to initialize mocks.

Just added a section on migrating given-on-it to the gherkin style.: https://spekframework.org/migration/#given-on-it (still needs improvement). The two are somewhat similar but not symmetrical.

You setup the context on Scenario, if you use memoized it caches by scope so Given/When/Then will see the same instance.

Think of Scenario as a test method in JUnit.

[robfletcher]

cool. I’ll give it a read.

That’g good for testing side effects on a subject (the set in the docs) is there a way to generate a memoized value in the When portion for testing the return value for something? It’s not clear what the appropriate structure is then unless I just use a Then which feels like I’m throwing the grammar out the window and is awkward if there are many Then blocks.

[robfletcher]

I can certainly perform the “action” inside the memoized lambda. e.g.

val response by memoized {
  service.getSomeData()
}

but if service relies on any mock/stub collaborators set up with beforeGroup that won’t work.

[raniejade]

Interesting, I would probably declare lateinit var response: Foo on Scenario. Other than that I can't think of any alternatives yet.
