Shift-left testing and its importance in software development


As a member of an Agile mobile app team, I can say that the prioritization of automation test cases is a huge problem. Most of the time, developers are busy building new features or fixing issues throughout out the Sprint. The testers are busy manually testing the app. By, the time they think about automation, new quarter arrives and new deliverables. The paradigm is changing now. Mobile apps are maturing and becoming more stable.
Concepts like DevOps and Shift-left testing have started to emerge.

What is DevOPS?

DevOps is not a strategy or a procedure, but rather a way to deal with empowering consistent application conveyance from origin to generation. Prior to the rise of DevOps, it was regular for enterprises to maintain separate development and operations groups. The absence of correspondence and cooperation between groups was, from various perspectives, a challenge to development and innovation in the team. The separation of development and operations was vexing for enterprises that received agile development, as utilizing agile methodologies expanded the quantity of new application works to create, test, and convey by a few requests of size. Rather than conveying another form to the operations group at regular intervals, engineers can create builds at a much higher rate.

The DevOps development began with dev and operations groups collaborated to address the difficulties of constant application delivery. An underlying objective was to “shift left” the obligations of operations, including operations much earlier in the SDLC. Next, developers were encouraged to code applications with operational concerns in mind from the beginning. In actuality, DevOps facilitates the interests and information sets of designers and operations managers, by utilizing the standards of lean advancement to make the procedure of CI and continuous delivery more seamless.

What is shift-left testing?
A solution to the traditional code first test, test later development methodology.
Common Nightmares of any software team:
Failure to deliver software on time.
Poor quality of the application.
Increased maintenance/bug fixing expenses.
Client loss from of poor testing.
Traditional application development approaches proved ineffective in meeting newer expectations.

The answer to all this: Shift-Left Testing

Shift Left Testing

With customary models, testing begins after the software is out of the coding stage. This would basically imply that a large portion of the testing action focuses on the wrong period of improvement, missing 56% of the bugs. There is a slim chance that these bugs are found during testing. In the event that they are found, this would mean enhancing the nature of officially corrupted programming.

The shift-left model emphasizes quality from the beginning of the task. This increases the likelihood of finding and correcting issues. As demonstrated below, testing from the beginning of the SDLC shortens the life cycle. The focus is placed on the early stages of testing to ensure a functionality and stability from day one.
