20 Smoke Testing Interview Questions and Answers

Smoke testing is a type of software testing that is used to determine if a software application is stable enough to be used. It is typically used as the first step in a testing process and is used to identify any major bugs or issues with the software. If you are interviewing for a position that involves smoke testing, you can expect to be asked questions about your experience and knowledge of the process. In this article, we review some common smoke testing questions and how you should answer them.

Smoke Testing Interview Questions and Answers

Here are 20 commonly asked Smoke Testing interview questions and answers to prepare you for your interview:

1. What is Smoke Testing?

Smoke Testing is a type of software testing that is typically used to determine whether a software program is stable enough to be used. This is done by running the program and checking for any crashes or major errors. If the program is able to run without any major issues, then it is considered to be stable and can be used.

2. When should Smoke testing be done in the Software Development Life Cycle (SDLC)?

Smoke testing should be done early in the SDLC in order to ensure that the most important functionality of the software is working as expected. This type of testing can be done manually or with automated tools, and it is typically used to give developers an early indication of whether or not the software is stable enough to continue with further testing.

3. How do you decide which tests to include in a smoke test suite?

A smoke test suite is typically made up of a small set of tests that exercise the most important functionality of a software application. The goal of a smoke test is to ensure that the most important functionality is working properly before proceeding with further testing. When deciding which tests to include in a smoke test suite, it is important to consult with stakeholders to identify the most important functionality of the application. Once this has been determined, a small set of tests should be designed to exercise this functionality.

4. Can you explain what the goal of smoke testing is and how it differs from other types of software testing like unit, integration, or regression testing?

The goal of smoke testing is to ensure that the most important functionality of a software application is working correctly. This type of testing is typically done early on in the software development process, before more detailed unit, integration, or regression testing is conducted. Smoke testing can be used to quickly identify any major issues with a software application before more time is invested in further testing.

5. Is it possible to automate smoke testing? If yes, then how?

Yes, it is possible to automate smoke testing. This can be done using a tool like Selenium.

6. What are some examples of negative scenarios that can be included in a smoke test plan?

A few examples of negative scenarios that can be included in a smoke test plan are:
-Attempting to log in with an invalid username and password
-Attempting to access a page that does not exist
-Attempting to submit a form with missing or invalid information

7. Can you explain what the difference between positive and negative testing is?

Positive testing is when you test the system to see if it behaves as expected. Negative testing is when you test the system to see if it behaves in an unexpected way.

8. Do you need to have knowledge about the codebase in order to write effective automated smoke tests?

While it can be helpful to have some understanding of the codebase in order to write effective automated smoke tests, it is not strictly necessary. The goal of a smoke test is simply to ensure that the most important functionality of the application is working as expected. As long as the smoke tests are covering the most important functionality, then they will be effective.

9. Is it possible to perform smoke testing on an existing application where there’s no documentation available? If yes, how?

Yes, it is possible to perform smoke testing on an existing application where there’s no documentation available. One way to do this would be to look at the application’s user interface and try to identify any key functionality that the application should have. Once you’ve identified this key functionality, you can then create a series of test cases to exercise these key areas of the application. This will help to ensure that the application is functioning correctly and can help to uncover any potential issues.

10. What does a smoke test report look like?

A smoke test report is a document that outlines the results of a smoke test. A smoke test is a test that is conducted to determine whether a system is stable enough to continue with further testing. A smoke test report should include information on what was tested, how the system performed, and any issues that were found.

11. Are there any recommended tools for creating smoke tests?

While there are many different ways to create smoke tests, one recommended tool is called SoapUI. This tool allows you to create test cases and test suites that can be used to test the functionality of web services.

12. What would you do when a smoke test fails?

The first step would be to check if the test can be reproduced. If it can be reproduced, then it is a valid failure and should be investigated further. If the test cannot be reproduced, then it is likely an invalid failure and can be ignored.

13. What happens if a bug is discovered during smoke testing?

If a bug is discovered during smoke testing, it is typically logged and then fixed before continuing with the testing process.

14. Does your team follow industry-standard best practices when writing/executing smoke tests?

Yes, our team follows industry-standard best practices when writing and executing smoke tests. This includes creating test cases that cover the most important functionality of the software, and running these tests early and often during the development process.

15. What are some things you’d consider when deciding whether to include manual or automated smoke tests into a release process?

There are a few things to consider when deciding whether to include manual or automated smoke tests into a release process. One is the time frame for the release – if time is tight, automated tests may be the only option. Another is the level of complexity of the release – if there are many moving parts, manual testing may be necessary to ensure that everything works as intended. Finally, the size of the team working on the release may also be a factor – if the team is small, manual testing may be the only practical option.

16. Why do you think smoke testing is important before executing more complex tests?

Smoke testing is important because it allows you to quickly identify any major issues with your software before you move on to more complex testing. This can save you a lot of time and effort, as you can fix any major issues before they become bigger problems.

17. How often should you run smoke tests?

Smoke tests should be run on a regular basis, but the frequency will depend on the project. For example, if you are working on a project with a lot of code changes, you will want to run smoke tests more often. If the project is more stable, you may only need to run smoke tests once a week or so.

18. Who owns the responsibility of writing smoke tests in your organization?

In our organization, the development team is responsible for writing smoke tests. This ensures that new code changes do not break existing functionality and that the application still meets the minimum requirements for functionality.

19. Can you give me some examples of real-world applications that use smoke tests?

Smoke tests are used in a variety of industries to test the functionality of products before they are released to the public. For example, in the software development industry, smoke tests are often used to test new software releases to ensure that they are stable and free of major bugs. In the automotive industry, smoke tests may be used to test new car models to ensure that they meet safety and emissions standards.

20. What are the prerequisites to using smoke testing effectively?

In order for smoke testing to be effective, you need to have a well-defined test plan and a set of test cases that cover the most important functionality of the software. You also need to have a way to track the results of the tests so that you can identify any areas that need further testing.
