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?

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

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.

<@U0B8HSTUG> your doing the correct way, you can move the `beforeGroup` inside `desribe("Injection")` which will be only executed for that group.

<@U0RNPHX0X> However as I said earlier :wink: I want this code to be run only once before all groups. Not just this test group, but all other test groups, too.

<https://github.com/rewe-digital/katana/tree/master/core/src/test/kotlin/org/rewedigital/katana>

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

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

you’re already doing it :slightly_smiling_face: declaring a `beforeGroup` just before the first describe. Just realised that I have a typo in my previous reply :joy: `then having on the root scope is fine -&gt; then having one on the root scope is fine`

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?

`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.

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