About Akka 2.5.12 Testkit

when i study AKKA, in the documentation i have found a Testkit part at Part 5: Querying Device Groups missing one function implements;like this:

Testing the query actor:

assertEqualTemperatures(expectedTemperatures, response.temperatures);

the function of assertEqualTemperatures how to do?
please friends could help me,thanks.

I found it, but it was a bit hard to track down as there is a 404’ed link from the tutorial:

  public static void assertEqualTemperatures(Map<String, DeviceGroup.TemperatureReading> expected, Map<String, DeviceGroup.TemperatureReading> actual) {
    for (Map.Entry<String, DeviceGroup.TemperatureReading> entry : expected.entrySet()) {
      DeviceGroup.TemperatureReading expectedReading = entry.getValue();
      DeviceGroup.TemperatureReading actualReading = actual.get(entry.getKey());
      assertEquals(expectedReading.getClass(), actualReading.getClass());
      if (expectedReading instanceof DeviceGroup.Temperature) {
        assertEquals(((DeviceGroup.Temperature) expectedReading).value, ((DeviceGroup.Temperature) actualReading).value, 0.01);
    assertEquals(expected.size(), actual.size());

Which I got from here: https://github.com/akka/akka/blob/master/akka-docs/src/test/java/jdocs/tutorial_5/DeviceGroupQueryTest.java

Maintainers: This is the 404’ed link in the tutorial:
Which is found at bottom of page here (and probably other locations too:

@bentito Thanks for answering :-) Please the up to date version of the docs, though: https://doc.akka.io/docs/akka/2.5.12/guide/tutorial.html?language=java The link works there.

Or better yet, always use the “current” link: https://doc.akka.io/docs/akka/current/guide/tutorial.html?language=java

Yes, that’s how to get to the file.
Note also that the code there is not doing anything akka specific – it is mostly plain old junit assertions, thus it was omitted as the guide focuses only on the relevant Akka parts.

PS: Please spell Akka as Akka, not all in caps :-)

Hope this helps!

Thank you very much.
