Below are the set1 of many testing interview questions and answers that we have in this website.
1. While at the stages of QA, QC and other testing phases what are the main documents that are referred?
The Quality related testing and testing phase in general requires each and every aspect of the project from customer specifications to developer designs. So the documents that are used can be summed up as:
ñ SRS & Business requirements doc.
ñ Functional/Technical documentation that was initially prepared.
ñ Documents pertaining to the various modules – used for White Box testing.
ñ Use case & other representative documents for program flow.
ñ Test plan and other test case/script related documents.
The test plan and its specification depends on the methodology adopted for development and testing of the project. But speaking on a top most level, the test plan should consist of all the different types of tests that have to be carried out to give the best assessment of the product. The compliance, production phase tests, regression test methods/scripts requirement, usability test, verification and validation criteria related tests should all be put into the test plan that is prepared.
3. What kinds of bugs usually occur and are identified in initial tests?
The major bugs that come up during the tests are the memory related issues in the software and these come up in the initial load testing or regression testing. There may be a minute error somewhere in the product which can lead to a very intensive impact on the overall application. These are the bugs that can also be easily identified and rectified. Tests should be carefully drafted to identify such memory related errors.
4. What is the purpose of software testing?
The software testing is the phase that gives us the overall picture as to the quality of the product and the performance related aspects of the program. The software testing phase is the one by which the developers can make sure that what is built is conforming to the customer’s requirement (verification) and that everything is working as expected and intended to (validation).
5. What are the pros and cons of being a Tester?
The software testing can be done only if you have a overall understanding regarding the project. This way software tester gains immense knowledge regarding the software, from the customer and the user perspective, which even the developer may not have in some cases. The cons are overcome by the pros of the job, so I think it is good thing to be involved in the software testing. Opportunities for learning and improvement are many in this field of software testing.
Some additional Tricky Testing interview questions
6. How can you define Quality Assurance?
The Quality Assurance refers to the phase of the project development where we examine the product and put into a sequence of various tests to determine if the product is fit for the specified purpose. The QA aims at attaining a specific quality level to the overall product. This cannot assure it but can maximize the quality attainable in the product by doing the right corrections to the final developed product.
7. How can you demarcate the QA line against the general testing?
The QA refers to the testing process that is aimed at giving the right perspective of the product from the high level of perspective, thereby determining the quality of the product from the eyes of the customer and the user. The Software testing is a more generic term used to refer any type of test that we do over a product to detect any type of error in the software. Thus the quality assurance can be seen as a specialized version of software testing, which again can be considered a part of software testing domain.
8. How can effectively scope out or organize a test project and execute it?
The test project has to be executed in a sequence that narrows it to the very specific reason for which it is run. The identification of the goal that pertains to each test project can help us in doing this. The test project can then be planned in modules or just into a single large batch execution which can identify the specific bug or error in the product that is under discussion. The organization of the test project can happen only if there is a right understanding in every team member as to what his responsibility in the test is.
9. How can a role of QA be utilized efficiently in a development project
The QA has to be effective and efficient in avoiding the bugs in the project. The test plan to detect conformance variation, deviation of the functionality has to be dictated and run by the QA periodically over the product at various stages of development. He has to make sure the project is heading in the right direction at various points of development. This is the best testing interview questions for most of the QA positions.
10. What is the ideal character that you expect from a manager?
The manager has to have the right mix of technical knowledge and the management skills. This can help him in understanding the use of the tests. The QA, QC and testing can be of great value to the project and the manager should be one who provides as much importance to testing stages as is given for development.
11. How can you define quality in a software product?
The quality refers to the conformance to the customer requirements in the most efficient way possible. The conformance should not be implicating some other side effect in some other perspective of the project. It should just be FIT to be used effectively. This is normally considered as prominent testing interview questions asked during interviews.
12. How is validation different from verification?
Simply put, the validation is the process of determining if the things are done the right way and the verification is the process of determining is the right things are done as per specification.
13. What are the things that are to be present in a good test process?
A good a valid test process should contain various aspects of testing and attributes that are configurable from the tester. The effect of each of the test cases should be clearly shown by the test process with a clear outlook given to the results as to which test conforms to which case of testing. The understanding of the results should be clearly brought out. These when done can give a good test process. If you are going to better it, then the test process can also specify the possible causes of the error that has occurred.
14. When can FMEA be of help to developers?
The Failure Mode and Effect Analysis is most effective when we are dealing with software products that have similarity to the previously developed applications. The experience of the developers/team other members in similar products can come in handy. The similarity of usage specifics and the structure of the design when identified implies we can have the FMEA oriented testing.
15. What is SDLC?
The Software Development Life Cycle refers to the overall development cycle of the software from the eyes of the System Analyst. The various stages of the development right from the requirements gathering to the final delivery after testing are included in the SDLC. The SDLC can further be defined as specific methodology that is incorporated as the way to proceed in the development of a specific software product. SDLC is very often asked testing interview questions in almost all junior to senior qa positions.
16. What should a perfect requirement specification contain?
A good requirement should give a clear business logic requirement, technical requirement for the product and rightly correlate each of those. The process requirements from the client are auxiliary but can be of immense help in coordinating the activities of developments with the customer side testing.
17. How is management of Quality in a project different from management of total project?
QA management comes into picture at the times of testing, the main aim is to verify the project is heading the right way. The project manager on the other hand manages the entire work flow and development flow in the project life cycle. There are also other aspects of the project like customer side interactions, business logic definitions etc. The project manager is one who manages the work done and the QA manager is one who oversees the work done for quality maintenance throughout, whether work done is right.
18. Share some of your QA experiences.
I was involved in the testing of the product that was for a project that had to support at least 30 items in the input criteria. The quality was measured as the number supported by the system. The test script was developed to simulate 20 or more input items. The testing on the periodic basis helped the developers to go in the right track and develop the various aspects of the product without affecting the number of items supported. This is where normally your interviewer will decide your job so this is important among all testing interview questions.
19. How can you bring about quality changes in adverse environments?
The quality changes in environments which are very static and not adaptable have to be done very carefully. Sometimes the quality changes may require change from the base in adverse environments, so spending good amount of time in designing the right architecture depending on the environment right from the start is essential when we are not sure about the adaptive nature of the environment or user.
20. Is test automation a required thing at all?
The tests in many cases are not a single execution of the program and there are always many cases to be tested. The immense number can be overwhelmingly high to think of manual testing. So in such a case the automation of testing with test scripts is the right way and the only possible way to go, considering the value of resources and man hours. This can be considered the smart way of working and most often this proves to be effective and efficient.
21. How can we have a effective phase containment concept incorporated into the project development cycle?
The testing should be done in parallel along with development over the various stages of deliverable. This way the errors are not propagating across the various phases of the project. This phase containment mechanism can result in avoiding defects in the final product that is being created. The more methodical and frequent we have the testing and workable product across the timeline the more effective the phase containment will be.
22. What are the various testing mechanisms you have done in your experience?
The regression, load tests and the module wise testing was done by me in the previous project that I was involved in. The regression testing gave the exact errors that were found in the application along with the appropriate test cases that have failed. The load testing was more of a stability test over the application and was to prove the quality of the product in terms of performance and stability to the customer. Both of them were automated and run at various stages of development.
23. How will you start with a new project, assuming you are put into a new team that is embarking on a new development project?
The first week will be purely dedicated to gaining of knowledge relating to the various technologies, methodologies used in the project. After this will be the phase where I will involve myself in getting to know more about the project that is being developed. The use cases, purpose of the project will be the start point and the modularity and design architecture will be analyzed by me and peer reviews and interactions with the team regarding the phases of testing and development will get me into the project completely.
After this the planning and execution of the test plan will help me ensure the project is going as expected from every aspect of view. This is rather not a regular testing interview questions but mostly asked for senior QA jobs.
24. How will you go about developing a test plan for a project?
That more often depends on the methodology used. Say, for example if there is RPD based development the test plan will be more interactive with the development plan. The modularity of the project, in every methodology has to be brought out in the test plan, so that the testing can recognize the potential areas of integration related weaknesses. The test plan also should impose upon the team members appropriate responsibilities so that each have their own perspective of delivery clear when it comes to test cases.
25. How do you expect a Software testing environment to be?
A Software testing environment should be very adaptable and should be configurable to simulate any kind of situation for the product under test. The exhaustiveness of the testing is directly related to the configurable aspect of the environment.
26. Do you have any prior experience in writing test cases? How did you proceed writing them?
Yes, I do have experience in writing test cases for the testing purposes of the project. The test cases should have a clear input category and output category. The inputs should be pertaining to the test’s aim. The output should automatically be scanned for correctness for deciding the failure/success demarcation. The test case also conforms to specific requirement from the client side or atleast a part of it. To ensure the correctness and validity of the output, we should be having the right idea of the customer expectation. Once we have the sufficient knowledge in the above aspects, we can have the best test case with apt goal to satisfy from the customer’s standpoint.
