Anyone have a guide on setting up junit tests (or equivalent for js files/projects?

[anton.bannykh]

fitzoh: Hi Andrew! I don't think there is such a guide at the moment. Currently the support for unit testing is limited to QUnit v1 (we are working on improving that). What you can do right now is add kotlin-test to your test module dependencies, and then write tests like so:

import kotlin.test.*
import org.junit.Test

class SomeTest {

    @Test fun testTest() {
        // Your test here
    }

}

[fitzoh]

Are those tests runnable in intellij?

[fitzoh]

There’s a run button in the gutter but when I click it I get a nothing here

[fitzoh]

and gradle test doesn’t seem to run that either

[fitzoh]

@anton.bannykh

[anton.bannykh]

No, those tests are not runnable in intellij at the moment.

[fitzoh]

so how do you run them?

[anton.bannykh]

One way to run them would be by setting up a node configuration and launching it with NodeJs plugin

[anton.bannykh]

Another would be using the https://github.com/srs/gradle-node-plugin and doing basically the same thing but via gradle

[anton.bannykh]

If you are using Gradle, here is an example of how to run Karma + QUnit: https://github.com/JetBrains/kotlin/blob/master/libraries/stdlib/js/build.gradle#L255

@fitzoh By the way, are you just testing the waters, or do you have a certain use-case?

[fitzoh]

just trying to test some business logic

[fitzoh]

no browser/js specific stuff

[fitzoh]

foundhttps://github.com/Kotlin/kotlin-frontend-plugin and I’ve got karma running, still can’t get an actual test to execute

[anton.bannykh]

Did you try the frontend-only example? Does it work on your machine?

[anton.bannykh]

@fitzoh Do you see the test results in the browser (http://localhost:9876/), but neither in the IDE nor in console?

[anton.bannykh]

@cy ^^^

[fitzoh]

Out at lunch... I went to the karma page and sae an error about require not being defined... I'll try cloning the front end example when I get back, was just copy pasting into the existing project at first

[fitzoh]

just got back, cloned the project and the frontend example looks good

[fitzoh]

copied the setup wholesale to the new project and that works too, not sure what I was missing

[anton.bannykh]

Cool 😃

[gaetan]

For my particular project I did a partial port of kotlintest and launch my tests in a single page: http://data2viz.io/dist/tests.html

[fitzoh]

that’s pretty cool

[fitzoh]

Not being able to quote test names in js makes me sad though 😞

[gaetan]

You can find the code of the port here: https://github.com/data2viz/data2viz/tree/master/tests/src/io/data2viz/test

I had configured with jest to run entirely in node.
