Are we supposed to use the check task to run tests in kotlin-multiplatform for the common code? I'm running check, and it's succeeded but isn't really doing anything

What do you mean is is not doing anything? In my project I have created several unit tests for the common module (my targets are jvm and iOS). Running the check task you execute all the unit tests (for iOS you’ll have to add an extra task to run the tests on a simulator)

Here's the output:

Testing started at 09:50 ...
09:50:56: Executing task 'check'...

> Configure project :
Kotlin Multiplatform Projects are an experimental feature.
> Task :check UP-TO-DATE
BUILD SUCCESSFUL in 0s
09:50:56: Task execution finished 'check'.

And then in another pane it says Tests passed: 0

I have one test with an assert, and i also added a println for good measure

[Diego]

I was about to suggest that (make a test fail)

Can you share your build.gradle file?

[Diego]

What is your project structure? By default all the common code goes in the commonMain folder and the tests goes in commonTest folder

here's my commonTest block from `build.gradle`:

commonTest {
            dependencies {
                implementation deps.kotlin.test.common
                implementation deps.kotlin.test.annotations
            }
        }

(deps is a dictionary used to organize our deps 🙂)

[Diego]

Check you have these two lines in your commonTest dependencies:

implementation 'org.jetbrains.kotlin:kotlin-test'
implementation 'org.jetbrains.kotlin:kotlin-test-junit'

In my project I just commented out these lines, run check and the build was successful so check you have them both in order to be able to run the tests for common.

[basher]

Still nothing unfortunately. When you run check, it runs tests for you?

[Diego]

Yes

I'm not building for JDK locally. I'm betting you happen to be though, which is why it's working? unsure though
