Software Engineering Tutorials

The basic idea of prototyping model is instead of fixing requirements before design and coding can begin ,a prototype is built to understand the requirements .the prototype is built with
the know requirements by this the user can be know how the system works

Rad Model :- Rapid Application development is high speed adaption of the linear sequential model in which rapid development is achieved by using component based construction ,business model
and data modeling etc.
Incremental Model : - Incremental model delivers software in small but usable pieces called increments .In general each increment builds on those that have already been delivered. In this analysis, design,
coding and testing are done for every model.
How can u measure the quality of your project
Some sdlc models
Explain Waterfall model and say what is the output in each phase?
Types of testing

Levels of testing

Unit testing :- Generally the code which is generated are compiled. The unit test is white box oriented and the steps can be conducted in parallel for multiple components.
1.The module Interface is tested to ensure that information properly flows into and out of the
program unit under test.
2.The local data structure is examined to ensure that data stored temporarily maintains its
intergrity during all steps in an algorithm's execution.
3.Boundary conditions are tested to ensure that the module operates properly at boundaries
established to limit and restrict processing
4.All the statements are executed at least once and error handling paths are tested
Integration testing:- Integration testing is a systematic technique for constructing the program structure .In integration test you have like
Top down :- Top down integration testing with the main routine and one or two immediate subordinate routines in the system structure it is good to have modules are integrated as they are
developed, top level interfaces are tested first
Bottom up :- Bottom up integration testing is the traditional strategy used to integrate the components of a software system into a functioning whole
Regressive testing :-
