42. What is Quality Assurance?
43. What is Cost of Quality?
44. What is the Cost of Correcting Defects?
45. What are the advantages and disadvantages of Black-Box Testing?
|Well suited and efficient for large code segments.||Limited coverage, since only a selected number of test scenarios is actually performed.|
|Code access is not required.||Inefficient testing, tester only has limited knowledge about an application.|
|Clearly separates user's perspective from the developer's perspective through visibly defined roles.||Blind coverage, since the tester cannot target specific code segments or errorprone areas.|
|Large numbers of moderately skilled testers can test the application with no knowledge of implementation, programming language, or operating systems.||The test cases are difficult to design.|
46. What are the advantages and disadvantages of White-Box Testing?
|Direct statement by statement testing||Vast resource needed|
|Check algorithm are correctly defined and coded.||Cannot test performance in terms of availability, reliability, load durability.|
|Adherence to coding standards.||Difficult to maintain|
|Measure coding quality||Costs are high|
47. What is the difference between validation and verification?
|Validation is a dynamic mechanism of validating and testing the actual product.||Verification is a static practice of verifying documents, design, code, and program.|
|It does involve executing the code.||It does not involve executing the code.|
|It is computer-based execution of program.||It is human-based checking of documents and files.|
|Validation to check whether the software meets the customer expectation and requirement.||Verification is to check whether the software conforms to the specification.|
|It can catch errors that verification cannot catch. It is a high-level exercise.||It can catch errors that validation cannot catch. It is a low-level exercise.|
48. What is the difference between cohesion and coupling?
|Cohesion is the concept of intra module||Coupling is the concept of inter module|
|Cohesion represents the relationship within module||Coupling represents the relationship between module|
|Increasing in cohesion is good for software.||Increasing in coupling is avoided for software.|
|Highly cohesive give the best software||Loosely coupling give the best software|
|Module focus on the single thing||Module is connected to the other module.|
49. What is the difference between Alpha and Beta testing?
|Alpha Testing||Beta Testing|
|Perform by developer||Perform by customer|
|Conducted for software application||Conducted for software product|
|Performed in virtual environment||Performed in a real environment|
|Involves both white box and black box testing||Involves black box testing|
|It is not open to the market and public||It is open to the market and public|
50. What is the difference between Quality Control and Quality Assurance?
|Quality Assurance||Quality Control|
|QA is a managing tool||QC is a correcting tool|
|QA is process oriented||QC is product oriented|
|QA use proactive strategy||QC use reactive strategy|
|QA use for prevention of defects||QC use for detection of defects|
|Everyone is responsible||Testing team is responsible|
