1, What do you mean by unit testing?
Unit testing is process of testing the particular complied program, such that ., a window, a report, an interface, etc. independently as a stand alone component or an program. The types and degrees of unit tests can vary among the modified and newly created programs. Unit testing is mainly performed by programmers who are also responsible for creation of the necessary unit test data.
2. What are various categories of debugging?
The various categories for debugging are as Follows :
Brute force debugging
Backtracking
Cause elimination
Program slicing
Fault tree analysis
3.What do you mean By incremental testing?
Regression testing is not a level of testing, but it is retesting of software that occurs when changes are made to ensure that new version of software has retained capabilities of the old version and that no new defects have been introduced due to changes.
4. Mention the difference between black box and white box testing?
Black box testing is a testing strategy based solely on the requirements and specifications. Black box testing requires no knowledge of internal paths, structures, or implementation of the software being tested.whereas
White box testing is a testing strategy based on the internal paths, code structures, and implementation of the software being tested. White box testing generally requires detailed programming skills.
5. What are the Different characteristic of process?
Any process has the following characteristics which are as Follows:
The process prescribes all of major process activities.
The process uses the resources, subject to a set of the constraints (such as a schedule), and produces intermediate and final products.
The process may be composed of the sub processes that are linked in some way. The process may be defined as a hierarchy of processes, organized so that each sub process has its own process model.
Each process activity has entry and exit criteria, so that we can know when the activity begins and ends.
The activities are organized in a sequence, so that it is clear when one activity is performed relative to the other activities.
Every process has a set of guiding the principles that explain the goals of each activity.
6. What are advantages of waterfall model?
The various advantages of the waterfall model are as follows:
It is a linear model.
It is a segmental model.
It is systematic and sequential.
It is a simple one.
It has proper documentation
7. What is RAD Explain?
The RAD ( stand for Rapid Application Development Model) model is proposed when requirements and solutions can be modularized as independent system / software components, each of which can be developed by the different teams. After these smaller system components are developed, they are integrated to produce large software system solution.
8. What do you mean by term system integration testing?
Testing of software components that have been distributed across the multiple platforms (ex., client, web server, application server, and database server) to produce failures caused by system integration defects (such that defects involving distribution and back office integration).
9. What are the Different types of attributes?
The Different Types of attributes are as follows
Simple Attribute
Composite Attribute
Single Valued Attribute
Multivalued Attribute
Derived Attribute
