Q. What is reverse engineering?
Ans. It is a method of analysing software with a view to understanding its design and specification.
- In source code, reverse engineering and executable code are the input.
- It may be part of a re-engineering process however may also be used to re-specify a system for re-implementation.
- Reverse engineering often proceeds re-engineering however is sometimes worth wise in its own right.
- Builds a program database as well as generates information from this.
- Program understanding tools (browsers and cross reference etc.) may as well be used in this process.
- Design in addition to specification may be reverse engineer to

What are the benefits of modular design? Changes made during testing and maintenance becomes manageable and they do not affect other modules.
Testing method to satisfy coverage criteria which need that for each decision point, every possible branch [outcome] be implemented at least once. Contrast with testing, path; test
Bottom up design: This design leads to a style of design where we decide how to join these modules to give larger ones; to combine those to give even larger ones, and so on, till
Explain Error guessing? Ans) Test data selection method. The selection criterion is to pick values that seem likely to reason errors.
State the process of White box testing White box testing: This method, also termed as glass box testing, is performed early in testing process. By using this, software engi
