Hi all, is there a way in Spek 2.0 to run some test initialization code once before all tests (of all groups) are run? So something like beforeGroup but with a greater scope?

[raniejade]

Can you post a snippet on what you are trying to achieve?

[svenjacobs]

Please see here https://github.com/rewe-digital/katana/blob/master/core/src/test/kotlin/org/rewedigital/katana/InjectionTests.kt#L18

This works however I would like to execute this line once before all tests from all groups are run.

[raniejade]

@svenjacobs your doing the correct way, you can move the beforeGroup inside desribe("Injection") which will be only executed for that group.

[svenjacobs]

@raniejade However as I said earlier 😉 I want this code to be run only once before all groups. Not just this test group, but all other test groups, too.

then having on the root scope is fine. You get an extra execution for the root scope, is that ok?

[svenjacobs]

How do I declare a root scope? Can you please show an example?

[raniejade]

you’re already doing it 🙂 declaring a beforeGroup just before the first describe. Just realised that I have a typo in my previous reply 😂 then having on the root scope is fine -> then having one on the root scope is fine

[svenjacobs]

But how can I assure that the test group with beforeGroup is run as the first test when I run ./gradlew test? Are they called in alphabetical order? So will A_Test.kt run before B_Test.kt? And what if an order is not guaranteed?

[raniejade]

beforeGroup is not global and won’t affect other classes.

class A: Spek({
  beforeGroup { ... }
})

class B: Spek({
  beforeGroup { ... }
})

beforeGroup on A and B are isolated.

[svenjacobs]

I know but I need a global solution

[raniejade]

there’s no global solution. You can create an extension then just invoke it on all of your tests.
