Prepare for the article purprose the example code where instead of using the "bmunit-extension" library the native java mechanisms will be used for tests purpose.
For example for test https://github.com/starnowski/bmunit-extension/blob/master/junit4-spock-spring-demo/src/test/java/com/github/starnowski/bmunit/extension/junit4/spock/spring/demo/controllers/UserControllerTest.java
try to use the "java.util.concurrent.CountDownLatch" type just like in example on page https://stackoverflow.com/questions/17827022/how-is-countdownlatch-used-in-java-multithreading
