I’m in general new to testing, and currently the setting for testing is using junit5 as test runner and using the assertions from kotest.

// part of build.gradle.kts
testImplementation(kotlin("test-junit5"))
    testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:5.6.2")

// kotest    testImplementation("io.kotest:kotest-assertions-core-jvm:4.1.0.291-SNAPSHOT")

For my use case, I have a function which would return the same value, say

0

for some invalid input, and when I test invalid inputs, I didn’t want to write multiple duplicate lines of

… shouldBe 0

. So I started to wonder if there is a better way.
