18.Define traceability matrix?
The relationship between requirements and test cases is shown by document and this document is known as traceability matrix.

It is a software testing technique which is used to divide the application input test data into each partition at least once of equivalent data from which test cases can be derived.
20.What is static testing?
Static testing tests and finds the defects without executing the code. It is don during verification process.
21.What are different test levels?
The different test levels are:
• System testing
• Unit/component/program/module testing
• Integration testing
• Acceptance testing
22.Explain Test Deliverables?
These are the set of documents, tools and other components that has to be maintained and developed in support of testing.

The categories of debugging are:
• Cause elimination
• Backtracking
• Program slicing
• Fault tree analysis
• Brute force debugging
24.What are the common risk that leads to project failure?
The common risks are:
• Time Limitations
• Not having enough human resource
• Limited Budget
• Testing Environment may not be set up properly
25.What is the use of test matrix?
Test matrix captures actual quality, the plan, effort, resources and time required to capture all phases of software testing.
26.What is the full form of LCSAJ?
LCSAJK stands for linear code sequence and jump.
27.What is the use of fuzz testing?
Fuzz testing detects security loopholes and coding errors in software.
28.What are the advantages of statement coverage metric of software testing?
The advantages are:
• Not require processing source code and can be applied directly to object code
• Bugs are distributed evenly through code, due to which percentage of executable statements covered is used to reflect the percentage of faults discovered.
29.Give the name of the different types of test coverage techniques?
The different types of test coverage techniques are:
• Decision Coverage
• Statement Coverage
• Path Coverage
30. What are the basic components of defect report format? id="Section30">The basic components of defect report format are:
• Snapshot of the defect
• Module Name
• Project Name
• Defect detected on
• Defect detected by
• Defect ID and Name
• Defect resolved by
• Defect resolved on
• Priority and Severity status
31.What is the purpose of end to end testing?
The purpose is
• Testing application in real world environment scenario
• To validate the software requirements and integration with external interfaces
• Testing of interaction between application and database
32.What are different types of verifications?
The different types of verification are:
• Inspection
• Walkthrough
33.Explain coverage?
Coverage is used to describe the degree to which the source code is tested.
34.What are the different types of coverage?
The different types of coverage are:
• Path coverage
• Decision coverage
• Statement coverage
35.What is component testing?
Testing of individual components is known as component testing.
36.What is the full form of CAST?
CAST stands for computer aided software testing.

43.What is Cyclomatic testing?
It is a measure of complexity of a module’s decision structure.
44.Which tool supports traceability, recording of incidents or scheduling of tests?
Dynamic analysis tool supports traceability, recording of incidents or scheduling of tests.
45.Which test activities are supported by test harness or unit test framework tools?
Test execution and logging are supported by test harness or unit test framework tools.

49.What are the weaknesses of random testing?
The weaknesses of random testing are:
• Many of the tests are redundant and unrealistic.
• You will spend more time analyzing results.
