Is testing supported in K/N platform modules in a Multiplatform configuration?

[olonho]

It shall be, using standard Kotlin testing APIs. Do you have any issues?

[Simone Civetta]

I guess my configuration is somehow wrong then

[Simone Civetta]

Do you have any pointer with a working multiplatform testing configuration?

[ilya.matveev]

Yes, tests are supported for mutliplatform projects. Although there is no special DSL for them yet you may build a test executable manually by adding extraOpts '-tr' in a program block. You can also find some example of multiplatform testing here: https://github.com/JetBrains/KotlinMultiplatformPlayground.

thank you very much @ilya.matveev

[Simone Civetta]

but why is commonSourceSets needed ? Shouldn’t it be inferred since its a MPP project?

[ilya.matveev]

By default the main source set is used and this should be enough for usual use cases (the most noticeable exception is common tests). commonSourceSets is just an option allowing one to use a custom source set with common sources.

[Simone Civetta]

Alright! I actually would have expected to declare commonSourceSets 'test' (instead of commonSourceSets 'main', 'test') since main is included by default

[ilya.matveev]

Originally this option is intended rather for overriding source set than for adding new ones. Using it for building a test binary is kind of a workaround and we will provide a more convenient DSL for test declaration.

Awesome, thank you!
