10 Unit Testing and Integration Tools and Libraries for Java Developers

Posted: 07 Jan 2019 04:40 AM PST

In last a couple of weeks, I have written some articles about what Java developer should learn in 2019 e.g. programming languages, libraries, and frameworks, but if you have just one thing to improve or learn then that must be your automation testing skills. Testing is one of the disciplines which separates professional developers with amateur ones. It's not about following TDD, BDD, or whatever testing methodologies but at the very minimum level, you must write code to test your code automatically. Many Java developers write unit tests and integration tests which automatically run during build time, mostly by using continuous integration tools like Jenkins or TeamCity.

I have been answering a lot of questions about what programmers should learn in 2019 and Docker Container is one of such skill. Docker and containers are a whole new way of developing and delivering applications and IT infrastructure. In this post, I'll talk about what is Docker and why a programmer should learn Docker. In today's world of massive scalability, where every single mobile app and web application needs to support billions of users (think of Youtube, WhatsApp, Uber), software application development and deployment have become increasingly complex. Gone are the days when software is developed by a small team of onshore people.

Difference between application/x-www-form-urlencoded and multipart/form-data in HTTP/HTML?

Recently in one of the Java web developer interview, one of my readers asked about the difference between x-www-form-url-encoded and multipart/form-data MIME types. In HTTP, there are two ways to send the HTML form data to the server either by using ContentType application/x-www-form-urlencoded or by using multipart/form-data. Even though both can be used to send both text and binary data to the server there is a subtle difference between them. In the case of x-www-form-urlencoded, the whole form data is sent as a long query string.
