ZTestLogger

A ZTestLogger is an implementation of a ZLogger that writes all log messages to an internal data structure. The contents of this data structure can be accessed using the logOutput operator. This makes it easy to write tests to verify that expected messages are being logged.

test("logging works") {
  for {
    _      <- ZIO.logDebug("It's alive!")
    output <- ZTestLogger.logOutput
  } yield assertTrue(output.length == 1) &&
    assertTrue(output(0).message() == "It's alive!") &&
    assertTrue(output(0).logLevel == LogLevel.Debug)
}
