What is Java Unit testing, and how do I learn it...


Java Unit testing is when you create small tests to verify that small bits of your code are working as “units.” Typically you write these tests in Java itself. In each test, you might get the system into a certain state, then you interact with the system to exercise the behavior you want to test. You finally verify whether or not the system did what you expected.
A primary goal is to reduce the number of defects that you integrate into the rest of the source base.
You’ll find numerous tutorial articles if you search. Most people use JUnit, a simple tool that you’ll find in Eclipse or IDEA.

    Unit testing is the software testing technique where a group of software program components or modules are tested individually. This technique effectively helps in validating the accuracy of a section of code by considering stubs, mock objects, drivers, and unit testing frameworks.

How to communicate two microservices with different ports?

  When two microservices need to communicate with each other but are running on different ports, there are a few approaches : 1.Direct Communication: If the microservices are deployed on the same network or infrastructure, they can communicate directly using their network addresses. You can use HTTP or any other appropriate protocol for communication. In this approach, each microservice would need to know the network address (IP address or domain name) and the port of the other microservice. Example: Microservice A running on port 8080 wants to communicate with Microservice B running on port 9090. Microservice A can make an HTTP request to Microservice B using its network address and port: HttpClient client = HttpClient.newHttpClient(); HttpRequest request = HttpRequest.newBuilder() .uri(URI.create("http://localhost:9090/api/resource")) .build(); HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString()); 2.Service Disco...
