Hello, I’m using a kotest TestFactory and trying to understand the lifecycle. It appears that the beforeTest /`afterTest` functions are executed but not the `beforeSpec`/`afterSpec` functions. Can someone help me understand why?

Code:

val myTestFactory: TestFactory = shouldSpec {
    beforeSpec {
        println("beforeSpec")
    }

    beforeTest {
        println("beforeTest")
    }

    afterSpec {
        println("afterSpec")
    }

    afterTest {
        println("afterTest")
    }

    should("help me understand the factory lifecycle") {
        println("during")
    }
}

class MyTest : ShouldSpec({
    include(myTestFactory)
})

Output:

I guess the before spec can't work, as the spec already exists before the factory methods are called. So maybe we should remove that from test factory.

[James Eschner]

Since a TestFactory can have more than one test in it it makes sense for it to have a lifecycle that’s similar to a regular spec. What I mean is that there should be facilities to run arbitrary code before and after each test as well as before and after all tests.

so like a beforeFactory kind of thing

beforeGroup

[James Eschner]

Sure, beforeGroup or beforeFactory both seem reasonable. This would be awesome to have, it took me some time to figure out what was going wrong.

why do your messages all say * not a contribution * at the bottom?

I was wondering that too 🙂

Here is the ticket for beforeGroup: https://github.com/kotest/kotest/issues/2188

[James Eschner]

One argument for keeping the name `beforeSpec`/`afterSpec` would be so that you could apply a TestListener that implements `beforeSpec`/`afterSpec` inside of a TestFactory
