7. What are the key challenges of software testing?
Correct Answer: Key Challenges of s/w testing: 1 Testing considered late in project 2 Requirements not testable 3 Integration is done after all components have been developed: This might result into full testing not being covered 4 Complete testing is not possible
8. What are the roles of glass-box and black-box testing tools?
Correct Answer: Glass Box (or white box) testing is the process of giving i/p to the system and checking how the system processes i/p to generate o/p Black Box testing is the process of giving i/p to the system and checking if the system is giving correct o/p without bothering how the o/p is generated As we can see from the definitions, the role of black box testing is to ensure that the o/p generated is correct And role of white box testing is to ensure that methods used to generate the o/p are correct
9. What methodologies have you used to develop test cases?
Correct Answer: I have used following 4 types of Methodologies: 1 Boundary value analysis 2 Equivalence partitioning 3 Error guessing 4 Cause effect graphing
10. Describe how to perform Risk Analysis during software testing.
Correct Answer: While a test plan is being created, risks involved in testing the product are to be taken into consideration along with possibility of their occurrence and the damage they may cause along with solutions; if any Detailed study of this is called as Risk Analysis Some of the risks could be: New Hardware New Technology New Automation Tool Sequence of code delivery Availability of application test resources Identify and describe the risk magnitude indicators: High, Medium and Low High magnitude means the effect of the risk would be very high and non-tolerable Company may face severe loss and its reputation is at risk Must be tested Medium: tolerable but not desirable Company may suffer financially but there is limited liability or loss of reputation Should be tested Low: tolerable Little or no external exposure Little or no financial loss Company?s reputation unaffected Might be tested Three perspectives of Risk Assessment: Effect, Cause and Likelihood To assess risk by Effect, identify a condition, event or action and try to determine its impact To asses risk by Cause is opposite of by Effect Begin by stating an undesirable event or condition and identify the set of events that could have permitted the condition to exist To asses risk by Likelihood is to determine the probability that a requirement will not be satisfied
