how are you running js tests

kpgalligan · Answer

JS tests don t run automatically You need to configure them to run AFAIK

GarouDan · Answer

I m running with something like gt gradlew jvmTest but gt gradlew jsTest never fails even changing the code I can make the jvm fail

GarouDan · Answer

< kpgalligan> what do you mean how can I do that

kpgalligan · Answer

I don t know I just know they don t run out of the box There are others here who focus a lot more on JS and I m sure can explain it better

ian.shaun.thomas · Answer

a few ways but one of the simple ways is to use one of the plugins to aid in this such as <https github com SalomonBrys Kotlin JS Gradle Utils>

ian.shaun.thomas · Answer

granted a plugin is not a requirement it just simplifies the process as the MPP plugin does not really have an opinion on how to run JS tests yet Hopefully in the future they shortcut some common ways to run JS tests so we don t need to depend on so much manual config or 3rd party utilities

GarouDan · Answer

Hum interesting Thanks < ian shaun thomas> I ll make an attempt here

russhwolf · Answer

I think the position of the Kotlin team last I recall was that they didn t want to take a position on what to use as the default js test framework mocha jest etc so they leave it to you to decide what you want to use

o O

GarouDan · Answer

I ve tried here and it works But I ve received a warning like the following ``` npm WARN saveError ENOENT no such file or directory open path build test js js package json ``` I ve seen the plugin has created the package lock json but not the actual package json

ian.shaun.thomas · Answer

yeah I am glad they aren t overly opinionated on the topic personally I wouldn t mind if they made a more formal testing utility for JS even if it lived outside the core plugin

ian.shaun.thomas · Answer

you can use this project as an implementation example <https github com ToxicBakery Arbor>

GarouDan · Answer

Either way I think the kotlin team could let us choose the test framework like this plugin did would not be a problem but not giving an option to execute the tests isn t too good

By the way a JS test runner that will work by default for the JS targets is on the way and will be released with Kotlin 1 3 40
