Manual Testing Interview Questions

Junior level: Manual testing interview questions

Normally Manual testing interview questions are asked in all types of testing job interviews. Whether it is Manual, Automated or even database testing. Because in Manual testing, all kind of basic and mandatory skills a tester needs to have will be covered.

1. Whats the difference between Manual testing and Automated testing?

Manual testing needs no tools, manually testers will check the functionality of the application by spending good amount of time. Where as in automated testing, testers use some automated tools such as QTP, Loadrunner, Winrunner to evaluate the functionality /performance of the application.

1.1 What is the use of Defect tracking tool? Which tool you are familiar with?te

Defect tracking is one of the important topic in manual testing process because any testing process will results in some or more defects and the testers will assign the defects to developers and then developers will fix the defect and re assign the defect to tester who has originally created it, and tester will re-test it and if it is pass the he will close the defect or else he will assign it back to developer who fixed.

The entire process is done using a tool called defect tracking tools and I am familiar with HP’s quality center , IBM’s clear quest. This is a must manual testing interview questions.

1.2 What is bug tracking tools?

Bug tracking and defect tracking are same so please refer to the above answer for this question.

1.3 What are the deliverable for a manual tester?

This is very important manual testing interview questions as at the end of the day we need to know what to deliver to test lead or manager? so below are the some important deliverables.

Testcase template, Test plan(mostly by leads), Defect documentation, Status of testing,

2.    What is the Waterfall Model?

The Waterfall model is one of the first models to be used for software testing. In this approach, the software development process is divided into separate phases.  These phases typically include requirements specification, software design, Integration and test, and maintenance.  Each phase cascades to the next.  That is, one phase doesn’t begin until the main goals of the previous phase is completed or signed-off.

3.    What is the V model?

The V model of the software development life cycle integrates testing into each phase of the model. The phases of this includes user requirements specification, system requirements specification, global design, detailed design, implementation, and testing of the system as a whole. In this model the phases are performed in parallel with development activities. There are four test levels in this model: component, integration, system and acceptance. This is not so important manual testing interview questions, so just read once and forget it.

4.    Explain regression testing.

Regression testing checks either a specific component of the application or the full application after revisions have been made. The purpose of regression testing is to guarantee that new defects have not been introduced in the application.  It is especially important to make sure that bugs have not been introduced into areas where no changes were made.

5.    What is stress testing?

Stress testing checks how robust the application is and involves verifying that that application consistently provides satisfying performance under unfavorable and extreme conditions.  This included, heavy user traffic, heavy process loads, irregular hardware clocking, and heavy utilization of resources.  It is also used to verify effectiveness of error handling under extreme conditions.

Stress testing is not a one of those specific manual testing interview questions, but it will be asked mostly for performance testing jobs.

6.    What is sanity testing?

Sanity testing is a basic test that is used to ensure that there are not multiple or conflicting functions or variables.   Basically, it verifies that the components of the application can be compiled without a problem.  This is conduction on all parts of the application.


manual testing interview questions7.    What is ad hoc testing?

Ad hoc testing software testing that is performed without the use of planning and/or documentation. They are typically run only one time unless a defect is found.  In these cases, testing may be repeated. Ad hoc testing is considered to be a part of exploratory testing.

8.    What is smoke testing?

Smoke testing covers all of the basic functionality of the application.  It does not explore the finer details of the application and is considered to be the main test geared towards checking the functionality of the application.

9.    Explain boundary value analysis.

Boundary value analysis is a black box testing method in which tests are based on boundary values in the application. A boundary value is an input/output value that is on the border of an equivalence partition. Or more simply put, the maximum or minimum value allowed.

10. What is the difference between priority and severity in regards to defects found in software testing?

In software testing, the priority of a defect is the level of importance from a business standpoint. Severity, however, is determined by the level of impact the defect will have on the system.  This impact can involve the development or the operation of a component or the whole system.

11. Explain compatibility testing.

Compatibility testing is a non-functional test performed on a software system or component for the purpose of evaluating its compatibility the other parts of the computing environment. This includes the hardware, servers, operating system, web browsers, other software, etc.

12. Explain integration testing.

Integration testing is testing that is performed to verify the interfaces between system components, interactions between the application and the hardware, file system, and other software. A developer can perform it, but ideally a different integration tester team should perform it. Integration testing is one of imp manual testing interview questions being asked.

13. What is equivalence class partitioning?

Equivalence partitioning is a testing technique that is used to minimize the occurrences of combinations and permutations of input data used for testing. With this method, input possibilities are sorted into equivalence classes in which data that have the same or similar affects are placed into the same class.  It assumes that the utility of the program will not change for any value of data from the same class. The tester assumes that it is adequate to choose one test case from every segment to verify system or component behavior. This reduces the effort required for testing by minimizing the number of test cases to be tested.

14. Provide and example that explains difference between usability and functional defects?

And example of the difference between usability and functional defect will be that of a Login window. A usability defect would be when a user enters a valid user name, but invalid password, and the application gives an error message of “Please enter a valid user name” when it should have been “Please enter a valid password.” A functionality defect would be if in the same scenario, the application accepts the name and the password, though one is incorrect.

15. Explain pilot testing.

Pilot testing is verifying a component of the system or the entire system under real time operating conditions. Using a real time environment helps to locate bugs in the system at an earlier time since the later a bug is found, the more costly it can be. Pilot testing often involves allowing a group of users access the system and implementing their feedback before it is completed and deployed to the public. Pilot testing is definitely a key manual testing interview questions for a company who is adopting a new tools or technologies for their existing application.

Tricky Manual Testing Interview Questions:

Interviewer may as well ask you some of the below questions for which you can get answers in the same blog. How can you write a test scenario? How do you make test cases from test scenario? How to make test scenarios from a requirements/functional specs? What are the important deliverable of a Manual Tester?

These are the generic manual testing interview questions.

  • If you do not have requirements then how do you start your testing process?
  • What were the most challenging tasks you handled in previous job?
  • How do you handle in most stressful times such as dead lines coming up but lot of work pending?
  • What do you need to write test cases?
  • Whom you approach if you have questions in writing /executing test cases?
