How to read a text file from resources in Kotlin?

Question

I want to write a Spek test in Kotlin. The test should read an HTML file from the src/test/resources folder. How to do it?

class MySpec : Spek({         


        

Answer 1

val fileContent = javaClass.getResource("/html/file.html").readText()

Answer 2

This is the way that I prefer to do it:

fun getResourceText(path: String): String {
    return File(ClassLoader.getSystemResource(path).file).readText()
}

Answer 3

private fun loadResource(file: String) = {}::class.java.getResource(file).readText()

Answer 4

You might find the File class useful:

import java.io.File

fun main(args: Array<String>) {
  val content = File("src/main/resources/input.txt").readText()
  print(content)
}
