Introduction

This library is a "workaround" the lack of real documentation & library for testing Intellij IDEA plugins in kotlin & with the kotlin stdLib presented.

There is an example under the example folder

Installation

Add the csense maven repo

groovy dsl

repositories {
    maven {
        url 'https://pkgs.dev.azure.com/csense-oss/csense-oss/_packaging/csense-oss/maven/v1'
        name 'csense-oss'
    }
}

kotlin gradle dsl

repositories {
    maven {
        setUrl("https://pkgs.dev.azure.com/csense-oss/csense-oss/_packaging/csense-oss/maven/v1")
        name = "Csense oss"
    }
}

Add the library

groovy dsl

dependencies {
    testImplementation "csense.idea.test:csense-idea-test:0.1.0"
}

kotlin gradle dsl

dependencies {
    testImplementation("csense.idea.test:csense-idea-test:0.1.0")
}

Getting started / steps explained

There are a few things to set up before any tests of sorts can work.

(the Example folder contains a simple example which the following steps will create)

1. the structure of tests can / are only tested as follows: adding this to gradle

     sourceSets {
   test {
       resources {
           srcDir("testData")
       }
   }
}

Then adding directly under the test folder a folder called "testData" (of cause you can customize this)

2. Add test fixtures inside here. as an "getting started example" you can use this in a "Example.kt"

fun main(args: Array<String>) {
    val exception = kotlin.KotlinNullPointerException() //this is to validate that we have loaded the standard library
    throw exception //just for the sake of it.
}

3. add a test in the test/kotlin/ you want as an example you can use ExampleTest.kt

@RunWith(JUnit4::class)
class ExampleTest : KotlinLightCodeInsightFixtureTestCaseLighter() {
    //The folder referenced again
    override fun getTestDataPath(): String = "src/test/testData/"

    @Test
    fun tryExample() {
        myFixture.testHighlighting("Example.kt")
    }

}

4. Tada, it should "just work" out of the box. (if somehow its utterly broken then perhaps setting idea home system property might solve some issues ( see https://plugins.jetbrains.com/docs/intellij/tests-prerequisites.html#set-the-run-configuration-parameters))
