Agile is a software development methodology to build software incrementally using short iterations of 1 to 4 weeks so that the development is aligned with the changing business needs. Whereas the traditional “waterfall” approach has one discipline contribute to the project, then “throw it over the wall” to the next contributor, agile calls for collaborative cross-functional teams. Agile isn’t defined by a set of ceremonies or specific development techniques. Rather, agile is a group of methodologies that demonstrate a commitment to tight feedback cycles and continuous improvement. With Agile development methodology – In the Agile methodology, each project is broken up into several ‘Iterations’. All Iterations should be of the same time duration (between 2 to 8 weeks). At the end of each iteration a working product should be delivered. In simple terms, in the Agile approach the project will be broken up into 10 releases (assuming each iteration is set to last… Read more“Agile Methodology of Development”

Test Driven Development
TDD is just about writing the test before the program. In other words, first think about “how to use” any component, why do we need this component or what’s it for? And only then think “how to implement”. Hence we can say, it’s a testing techniques as well as design techniques. Below are the advantages of it, It results into components that are easy to test. It results into components that are easy to enhance and adapt. In the end, there is no code without a test. We can tell at any time, whether everything still works as it should, or what exactly does no longer work as it once did. Complex things won’t fear us, execute the test and get positive feedback. You can re-use the unit test in accessing the performance of your system early stage of software lifecycles. Why test first? The test is the executable specification….
