What is design pattern?  In software engineering, a  design pattern  is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. Uses of Design Patterns Design patterns can speed up the development process by providing tested, proven development paradigms. Effective software design requires considering issues that may not become visible until later in the implementation. Reusing design patterns helps to prevent subtle issues that can cause major problems and improves code readability for coders and architects familiar with the patterns. Often, people only understand how to apply certain software design techniques to certain problems. These techniques are difficult to apply to a broader range of problems. Design patterns provide general solutions, documented in a format

a. What is test automation?  Test automation is the practice of running tests automatically, managing test data, and utilizing results to improve software quality. b. What are the benefits of automating a test case?  1. Faster Feedback Cycle Without test automation, feedback for newly developed features can take a while. Test automation helps you reduce the feedback cycle and bring faster validation for phases in the development of your product. Test automation is especially useful because it helps you detect problems or bugs early on during the development phase, which increases the team’s efficiency.  2. Team Saves Time By automating your testing procedure, your team has to spend less time validating newly developed features. It also improves communication with other departments like marketing, design, or product owners who rely on the results of these tests. These departments can easily check the logs of the automated tests and see what’s happening. 3. Reduced Business Expenses When

What is CI, CD, CT?  Continuous integration (CI), continuous delivery/deployment (CD), and continuous testing (CT) accelerate the code release process and help with deployment. IT organizations are increasingly turning to DevOps practices to improve value delivery for the customer. When DevOps implements CI, CD, and CT methods  correctly , releases become more reliable and error-free. This, in turn, leads to  higher productivity, efficiency, and customer satisfaction . Background We will talk about each of these – CI, CD, and CT – in detail and their role in DevOps. They are the main methods to measure successful DevOps practice. We will talk about how they make DevOps practices more trouble-free. The discussion around them is important because now, with DevOps, developers receive feedback from stakeholders  and  tools that systematically monitor and test their code in the pipeline. Enter: CI, CD, and CT. Summary What to expect: What is CI in DevOps? What is CD in DevOps? What is CT in
