Testing documentaion is still to be made. More comprehensive documentation on testing will be done in the near future. In the mean time you can have a look at the Akkatecture.Tests project on github to get an idea of how to test your domain. Akkatecture is also working on a test fixture for testing aggregates, so far you can find its usage here but the test fixture package is still to be released to nuget, stay tuned for updates. The test fixture package is supposed to allow you to express business domain tests in a style that mimmics actual domain usage, using the raw akka.net test kit to do this is a little bit bloated for most cases. However, feel free to suppliment the test fixture with petabridge's actor testing documentation using akka.net TestKit to get a good idea about how to tests a project like this effectively.
