Hey,
We are using StringSpec tests. They look like this:

init {
        "test that something works" {
            val rules = setupMocks()
            ...
        }
     ...

When I run the test suite I cant see the test that something works text.
How can I enable this? Using Spring

[Emil Kantis]

can you clarify how you're running the test suite, and show a screen shot of where you expect to see the text?

[John Herrlin]

This is how I run the test suite: time mvn '-Dos.detected.classifier=osx-x86_64' -U clean install

[John Herrlin]

I would expect "test that something works" to be included in the output to stdout

[John Herrlin]

but it's not, and it makes it really hard to pinpoint what test that failed

[sam]

does install run tests ?

[sam]

what about mvn clean test ?

[John Herrlin]

Yes it does. Let me see

[sam]

Did you setup the surefire plugin to run tests

[John Herrlin]

Good question, im not the one who set it up, let me find out

[John Herrlin]

I could not find anything related to surefire in my codebase

[John Herrlin]

mvn clean test works fine, but it doesnt print "test that something works" to stdout

[Emil Kantis]

So what's configured to run tests? Surefire is one such plugin, which integrates with JUnit platform (Which Kotest also integrates with.)

[John Herrlin]

[INFO] --- maven-surefire-plugin:3.0.0-M7:test (default-test) @ service ---
[INFO] Using auto detected provider org.apache.maven.surefire.junitplatform.JUnitPlatformProvider

So it seems that Im using surefire, sorry for that

[Emil Kantis]

Do you have kotest-runner-junit5-jvm dependency added to your classpath?

[John Herrlin]

Yeah I looks like so.

@John Herrlin hmm did the test run but it just didn’t output anything? can you add this

object TestPrinterListener : TestListener {
  /**
   * Resolves the test name together with all the contexts, separated by "-"
   *
   * context - when something - when another - should do xyz
   */
  private tailrec fun resolveTestName(
    current: TestCase,
    separator: String = " - ",
    acc: String = ""
  ): String {
    val name = if (acc.isEmpty()) current.name.testName else "${current.name.testName}$separator$acc"
    return when (val parent = current.parent) {
      null -> name
      else -> resolveTestName(parent, separator, name)
    }
  }

  override suspend fun finalizeSpec(kclass: KClass<out Spec>, results: Map<TestCase, TestResult>) {
    val testCases = results.filter { it.key.type == TestType.Test }
    println(
      listOf(
        "~~~ ${kclass.simpleName} ~~~",
        *testCases
          .map { (testCase, result) -> "  + ${resolveTestName(testCase)}: TestResult=$result" }
          .toTypedArray()
      ).joinToString("\n", "\n")
    )
  }
}

and then register it in your `ProjectConfig`:

class ProjectConfig : AbstractProjectConfig() {
  override fun extensions(): List<Extension> = listOf(
    TestPrinterListener,
    // SpringAutowireConstructorExtension, 
    // JunitXmlReporter(includeContainers = false, useTestPathAsName = true),
    // ...
  )
}

[mitch]

see if it prints out anything?
