The workflow of the functionality involved executing a series of interconnected complex steps across numerous machines. As one would expect, this is for crunching numbers to generate desired reports.
Earlier, I had mentioned some of the common excuses people give to not write tests.

Because it is a ticking time bomb waiting to explode. Jumping straight to the point.
Javascript frameworks have skyrocketed in the recent times especially the big 3 -- Vue, React and Angular have made the front end development way too painless. Amidst this rapid adoption by the larger developer community, jQuery seems to be done away with.

With the advent of higher resolution devices increasing every day and the need for the end users to getting used to seeing high-res images, anything that is default or standard definition looks inferior if not ugly. As a developer, it is a must to consider this design impact and how to accommodate and give a seamless experience to the end user across various types of devices. I am going to quickly touch base on how to understand what High Dpi devices are how to exploit all those pixels available in a device real estate.
Test Driven Development TDD and Behaviour Driven Development have been around for long time and is one of the most efficient ways to develop software.

There are times where you will need to bypass certain restrictions related to country especially when you are scraping from a cloud machine.

Building a team is one of the most important aspects of any organisation. The team should have the right ingredients of experienced people and young people. The experienced members help in holding the team together, at the same time will mentor the young people. For example, take the recent IPL final between Chennai Super Kings and Sunrisers Hyderabad. CSK had the right blend of experience and youth. They had more of experienced members but had only selected the younger player in whom they saw the potential and used them in the way that was best suited for them. This is one of the ways a winning team can be built in which the young people can be nurtured. In a team-oriented culture, each person contributes to the organisation’s success. Team members who are individual contributions to the team should always be recognised. This will strengthen the team spirit among all its members and will help in maintaining a good relationship among the members.
