Explain Software Testing. Why is it important to conduct the testing of a software?

Correct Answer: Quality Assurance Manager (QA Manager) defines the process to be followed at each phase of SDLC He defines the standards to be followed, the documents to be maintained and sets the standard for the product Where as it is the Project Manager?s responsibility to ensure that the things defined by QA manager are being implemented He develops the product from start to finish with his team and ensures that the product which is to be rolled out is Defect free and it reaches the standards and views defined by QA Manager QA managers can audit the process for certain time periods which are being handled by the Project Manager

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

Correct Answer: I have used following 4 types of Methodologies: 1 Boundary value analysis 2 Equivalence partitioning 3 Error guessing 4 Cause effect graphing

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

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

Correct Answer: choice of hardware configuration for an application

Explanation:

Configuration management is not concerned with the choice of the hardware configuration for an application.

 

Configuration management is concerned with the development of procedures and standards for cost-effective managing and controlling charges in an evolving s/w system.

It includes

1)software versions maintenance

2)controlling changes in documentation

3)controlling changes to the source code

4) management activities

Correct Answer: How much regression testing should be done.

Explanation:

Impact Analysis is used in software testing to define all the risks associated with any kind of changes in a product being tested.

Impact Analysis is nothing but analyzing the impact of changes in the deployed product or application. It gives the information about the areas of the system that may be affected due to the change in the particular section or features of the application.

 

Why Impact Analysis is done :

1. It is done to understand the possible outcome of implementing the change. Inducing too much functionality into a product can reduce the overall performance of the product.

2. To identify all the files, documents and models that might have to be modified if team decides to implement the change in product

3. To estimate the effort needed behind implementing the change

4. To identify the task required to implement the change

5. It will list the dependencies on a specific element

 

The impact is analyzed on Requirements, Design & Architecture, impact on Test and impact on schedule.

Correct Answer: TRUE

Explanation:

Configuration Management is a support for software in managing the different items in the product, and changes in them.

Correct Answer: Structural Testing

Explanation:

Structural Testing is the other name for White Box Techniques.
