1) State Key Factors to be Tested in Black Box Testing 

Ans=>  Black box Testing is an eye to eye  base checking which checks how for software can function will  . This is required mainly to check for a software information will however one has to be aware of box that come in the ways of testing process the over all testing adapts a complete life cycle. . where there are number of stages like need integration ,system , acceptance , final and regression testing stage.

2) What are the sources of knowledge  of black box testing ?

Ans=> 1)Decision table testing 

             2) boundary value analysis 

             3) stage graph 

             4)causes effect graph 

             5) error guessing

             6)Equivalence Partioning 

3)State Advantages and Disadvantages of Black box Testing 

Ans=> 

a)Advantages of Black Box Testing

• Unbiased tests because the designer and tester work independently
• Tester is free from any pressure of knowledge of specific programming languages to test the reliability and functionality of an application / software
• Facilitates identification of contradictions and vagueness in functional specifications
• Test is performed from a user’s point-of-view and not of the designer’s
• Test cases can be designed immediately after the completion of specifications

b)Disadvantages  of Black Box Testing

• Tests can be redundant if already run by the software designer
• Test cases are extremely difficult to be designed without clear and concise specifications
• Testing every possible input stream is not possible because it is time-consuming and this would eventually leave many program paths untested
• Results might be overestimated at times
• Cannot be used for testing complex segments of code
