Hi ! I would like to add some unit tests in my Compose MP project generated with the online Wizard. What are the required steps ? (I'm editing on Fleet, but I can use Intellij Idea)

[Richard]

The only thing I know is that in Intellij you can simply right click on the class -> Generate -> Tests
Or something like that. It will create a Unit test file for you in the right place. You may have to add JUnit as Dependency

[loloof64]

Thank you : I try right now 😃

[Richard]

As far as I remember.

Unfortunately, I can't use Test annotation in the test source file. It is not recognized.

[loloof64]

So is there a universal testing framework for Kotlin Multiplatform ?

take a look at this video :

[loloof64]

Thank. I've been trying following his video yesterday, but even with it I don't manage to set up TDD.

[loloof64]

The Test annotation from kotlin.test is still not recognized

[loloof64]

Also I can't see the arrow buttons on the left of the editor.

[Mohamed Mabrouki]

have you added the correct kotlin test dependency to your commonTest in build.gradle shared module?

[loloof64]

These are my project configuration files. I've also synchronized Gradle and added configuration from the repository of the video.

build.gradle.ktslibs.versions.toml

[Mohamed Mabrouki]

everything seems correct

[Mohamed Mabrouki]

did you add test module this way ?

[loloof64]

I just added the commonTest/kotlin

[Mohamed Mabrouki]

and it still does not recognize the Test annotation?

[loloof64]

Right : still the same error

Alt+Enter => the popup just shows add TestNg and create new annotation Test

[loloof64]

The registered project dependencies

[loloof64]

kotlin-test 2.0.0 has no annotation Test

[Richard]

Maybe you first need to write the function syntax so that it knows you want to annotate a function

[Richard]

And you don't have an import statement as I see

Finally I managed

[loloof64]

I followed this page : https://medium.com/arconsis/unit-testing-using-kotest-in-kotlin-multiplatform-mobile-kmm-f351aa3f3977

[loloof64]

In build.gradle.kts I've added

val desktopTest by getting {
            dependencies {
                implementation(compose.desktop.uiTestJUnit4)
                implementation(compose.desktop.currentOs)
            }
        }

[loloof64]

and I used desktopTest/kotlin folder instead of commonTest/kotlin

👌

[loloof64]

I would like to have it set for commonTest, but for sure, as for now, that's enough 😃
