1. What is Exploratory Testing?
Exploratory testing is a hands-on approach in which testers are involved in minimum planning and maximum test execution. The planning involves the creation of a test charter, a short declaration of the scope of a short (1 to 2 hour) time-boxed test effort, the objectives and possible approaches to be used. The test design and test execution activities are performed in parallel typically without formally documenting the test conditions, test cases or test scripts. This does not mean that other, more formal testing techniques will not be used. For example, the tester may decide to use boundary value analysis but will think through and test the most important boundary values without necessarily writing them down. Some notes will be written during the exploratory-testing session, so that a report can be produced afterwards.
2. What is "use case testing"?
In order to identify and execute the functional requirement of an application from start to finish "use case" is used and the techniques used to do this is known as "Use Case Testing"

16. What are the valuable steps to resolve issues while testing?
17. What is the difference between test scenarios, test cases and test script?
Difference between test scenarios and test cases is that
Test Scenarios: Test scenario is prepared before the actual testing starts, it includes plans for testing product, number of team members, environmental condition, making test cases, making test plans and all the features that are to be tested for the product.
Test Cases: It is a document that contains the steps that has to be executed, it has been planned earlier.
Test Script: It is written in a programming language and it's a short program used to test part of functionality of the software system. In other words a written set of steps that should be performed manually.
18. What is Latent defect?
Latent defect: This defect is an existing defect in the system which does not cause any failure as the exact set of conditions has never been met
19. What are the two parameters which can be useful to know the quality of test execution?
To know the quality of test execution we can use two parameters
20. What is the function of software testing tool "phantom"?
Phantom is a freeware, and is used for windows GUI automation scripting language. It allows to take control of windows and functions automatically. It can simulate any combination of key strokes and mouse clicks as well as menus, lists and more.
21. Explain what is Test Deliverables ?
Test Deliverables are set of documents, tools and other components that has to be developed and maintained in support of testing.
There are different test deliverables at every phase of the software development lifecycle
22. What is mutation testing?
Mutation testing is a technique to identify if a set of test data or test case is useful by intentionally introducing various code changes (bugs) and retesting with original test data/ cases to determine if the bugs are detected.
23. What all things you should consider before selecting automation tools for the AUT?
24. How will you conduct Risk Analysis?
For the risk analysis following steps need to be implemented
25. What are the categories of debugging?
Categories for debugging
26. What is fault masking explain with example?
When presence of one defect hides the presence of another defect in the system is known as fault masking.
Example : If the "Negative Value" cause a firing of unhandled system exception, the developer will prevent the negative values inpu. This will resolve the issue and hide the defect of unhandled exception firing.
27. Explain what is Test Plan ? What are the information that should be covered in Test Plan ?
A test plan can be defined as a document describing the scope, approach, resources and schedule of testing activities and a test plan should cover the following details.
