You can make a great software but you have to choose 2 out of this above 3. There is no way to get around!

I had worked on spring framework extensively throughout my career. The one thing which I am always try to implement in any Spring project I work on is Custom annotation. Its a fancy stuff but useful in many ways. Say you have numerous micro services (Duplicate code bases which will f*** you up) running on your cluster, the best and first thing you do is - Build a common library to push all your model classes, so called util package of your organization :p and the fancy stuffs ....

When comes to any programming language what i check first is how to write a unit test on it. “Coding is not difficult- Bill Gates” So what is difficult? I would say testing is difficult. Here is a basic example on how to test a small piece of python code. The above snippet is a basic recursive program which will return the factorial of a number. Lets see how we can write a basic test case for this....
