How to read a text file from resources in Kotlin?
Solution 1:
val fileContent = MySpec::class.java.getResource("/html/file.html").readText()
Solution 2:
No idea why this is so hard, but the simplest way I've found (without having to refer to a particular class) is:
fun getResourceAsText(path: String): String? =
object {}.javaClass.getResource(path)?.readText()
It returns null
if no resource with this name is found (as documented).
And then passing in an absolute URL, e.g.
val html = getResourceAsText("/www/index.html")!!
Solution 3:
another slightly different solution:
@Test
fun basicTest() {
"/html/file.html".asResource {
// test on `it` here...
println(it)
}
}
fun String.asResource(work: (String) -> Unit) {
val content = this.javaClass::class.java.getResource(this).readText()
work(content)
}
Solution 4:
A slightly different solution:
class MySpec : Spek({
describe("blah blah") {
given("blah blah") {
var fileContent = ""
beforeEachTest {
html = this.javaClass.getResource("/html/file.html").readText()
}
it("should blah blah") {
...
}
}
}
})
