66 QA interview questions and answers(Part 3)
Q32. Describe Use Case Testing.
Use Case: A use case is a description of the process which is performed by the end user for a particular task. Use case contains a sequence of step which is performed by the end user to complete a specific task or a step by step process that describe how the application and end user interact with each other. Use case is written by the user point of view.
Use case Testing: the use case testing uses this use case to evaluate the application. So that, the tester can examines all the functionalities of the application. Use case testing cover whole application, tester performs this testing in step by step process to complete one task.
Q33. What type of tests you perform on the web based application?
For web application we perform following time of test:
1. Functionality Testing.
2. Usability Testing.
3. Navigation Testing.
4. Configuration and Compatibility testing.
5. Reliability and Availability Testing.

6. Performance Testing.
7. Load and Stress Testing.
8. Security Testing
Q34. What is Gantt Chart?
A Gantt Chart is used to represent a project schedule that includes duration of individual tasks or phases, their dependencies and ordering.
- It displays the start and end points of each task and the percentage of completion of each task
- It allows the planner to assess the duration of a project, identify the resources needed, and lay out the order in which tasks need to be performed.
- It is useful in managing the dependencies between tasks.
- Using Gantt chart each team member can view the product development schedule.
Q35 How to find all the Bugs during first round of Testing?
There could be several reasons for not debugging the entire bug in the first round of testing process. Debugging the showstopper in the first or second build is almost impossible. A found defect can cover up the other defects in the application. The thread which leads to on defect could be redirected to another defect, as the tester find the bug and lock that bug in report and after fixing of those bugs new bugs may also arises. It is difficult to keep testing on a known defective application. That is the reason we cannot find all the bug in first run and also we cannot perform Exhaustive testing.
Q36 How can u prepares the Test Plan without SRS?
We can prepare a test plan directly without having SRS, When the Requirements and URD(User Requirement Document )are available to us. URD is very helpful to determine the requirement of the user. The SRS document only contains the requirement of the user, but tester can also determine the requirement form the product. Without having SRS document we cannot estimate the Testing effort and cost of testing if we do not have SRS. SRS tell us on which platform our software is going to be used and on basis of this we perform the test on the application. Some time end user want to know what type of testing we are going to execute on the application for this we can send our test plan to the client.
Q37. What is the purpose of test strategy?
We need Test Strategy for the following reason:
1. To have a signed, sealed, and delivered document, where the document contains details about the testing methodology, test plan, and test cases.
2. Test strategy document tells us how the software product will be tested.
3. Test strategy document helps to review the test plan with the project team members.
4. It describes the roles, responsibilities and the resources required for the test and schedule.
5. When we create a test strategy document, we have to put into writing any testing issues requiring resolution.
6. The test strategy is decided first, before lower level decisions are made on the test plan, test design, and other testing issues.

Q38. What are the dimensions of the Risks?
The dimensions of the risk are described below:
Schedule: Unrealistic schedules. to develop a huge software in a single day..
Client: Ambiguous requirements definition, requirement and not clear, changes in the requirement etc.
Human Resources: Non-availability of sufficient resources with the skill level expected in the project.
System Resources: Non-availability of procuring all critical computer resources either hardware and software tools or licenses for software will have an adverse impact.
Quality: Compound factors like lack of resources along with a tight delivery schedule and frequent changes to requirements will have an impact on the quality of the product tested.
