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
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. Difference between system, integration and E2E tests System Testing This is the level of testing that validates the complete and fully integrated software product. The purpose of a system test is to evaluate compliance with its specified requirements and specifications. Usually, the software is only one element of a larger computer-based system. Ultimately, the software is interfaced with other software/hardware systems. System Testing is actually a series of different tests whose sole purpose is to exercise the full computer-based system. System testing seeks to detect defects both within the “inter-assemblages” and also within the system as a whole. The actual result is the behaviour produced or observed when a component or system is tested. system testing is carried out to achieve the following: Testing the fully integrated applications including external peripherals in order to check how components interact with one another and with the system as a whole.
