Software Testing Interview Questions and Answers For Freshers Part-5

Be First!

software-testing41. Why can be tester dependent on configuration management?

Because configuration management assures that we know the exact version of the testware and the test object.

42. What is a V-Model?

A software development model that illustrates how testing activities integrate with software development phases.

43. What is maintenance testing?

Triggered by modifications, migration or retirement of existing software

45. Can you explain the workbench concept?

In order to understand testing methodology we need to understand the workbench concept. A Workbench is a way of documenting how a specific activity has to be performed. A workbench is referred to as phases, steps, and tasks as shown in the following figure.
There are five tasks for every workbench:

Input: Every task needs some defined input and entrance criteria. So for every workbench we need defined inputs. Input forms the first steps of the workbench.
Execute: This is the main task of the workbench which will transform the input into the expected

Output.

Check: Check steps assure that the output after execution meets the desired result.
Production output: If the check is right the production output forms the exit criteria of the workbench.
Rework: During the check step if the output is not as desired then we need to again start from the execute step.

46. Can you explain the concept of defect cascading?

Defect cascading is a defect which is caused by another defect. One defect triggers the other defect. For instance, in the accounting application shown here there is a defect which leads to negative taxation. So the negative taxation defect affects the ledger which in turn affects four other modules.

47. Can you explain cohabiting software?

When we install the application at the end client it is very possible that on the same PC other applications also exist. It is also very possible that those applications share common DLLs, resources etc., with your application. There is a huge chance in such situations that your changes can affect the cohabiting software. So the best practice is after you install your application or after any changes, tell other application owners to run a test cycle on their application.

48. What are Test comparators?

Is it really a test if you put some inputs into some software, but never look to see whether the software produces the correct result? The essence of testing is to check whether the software produces the correct result, and to do that, we must compare what the software produces to what it should produce. A test comparator helps to automate aspects of that comparison.Who is responsible for document all the issues, problems and open point that were identified during the review meeting

49. What is the difference between pilot and beta testing?

The difference between pilot and beta testing is that pilot testing is nothing but actually using the product (limited to some users) and in beta testing we do not input real data, but it’s installed at the end customer to validate if the product can be used in production.

50. What is the role of moderator in review process?

The moderator (or review leader) leads the review process. He or she determines, in co-operation with the author, the type of review, approach and the composition of the review team. The moderator performs the entry check and the follow-up on the rework, in order to control the quality of the input and output of the review process. The moderator also schedules the meeting, disseminates documents before the meeting, coaches other team members, paces the meeting, leads possible discussions and stores the data that is collected.
