Create a SLF4J-compatible logging extension, which can be used to sniff logs

class MyTest : FunSpec(
  {
    val logs = install(LogSniffer) { minLevel = Level.INFO }

    test("check that logs are on correct level and contains id") {
       logs.forOne {
         it.level shouldBe Level.WARN
         it.message shouldContain "myId"
      }
    }
  }
)

Do you think it’s worth adding as an extension (kotest-extensions-logging?)?

What about just saying this was a good idea that didn’t work out 😃

@jschneidereit i meant to monitor the logs of the production code. 😃

for instance:

class Greeter {
  fun sayHello(name: String) {
    if (name.startsWith("jim")) { logger.warn("Jim was here") }
    println("Hello $name")
  }

  companion object {
    val logger = LoggerFactory.getLogger(Greeter::class.java)
  }
}

test:

test("Warns when jim is here") {
   Greeter().sayHello("jim")
   logs.forOne {
     it.level shouldBe Level.WARN
   }
}
