junit4

I wrote a simple example for threading which generates tables for numbers starting from 1 to 20. when I tested it with main method it executes all the threads (prints all the messages), while all threads are not being run (all messages are not being printed) most of the times (sometimes it runs all the threads) when doing the same with JUnit test. I think there should not be any difference in terms of output. Here is the class with main method: public class Calculator implements Runnable { private int number; Calculator(final int number){ this.number = number; } @Override public void run() {

I've started a new project: PostfixSQLConfig . It's a simple Spring Boot application that is essentialy supposed to provide CRUD access for 4 simple databse tables. I wrote the the repository for the first table and some basic integration tests for said repository. Since this particular table should not provide update functionality, I implemented update function as: @Override public void update(@NonNull Domain domain) throws NotUpdatableException { throw new NotUpdatableException("Domain entities are read-only"); } where NotUpdatableException is my custom exception class.
