50 Software Testing Interview Questions for Freshers

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 afterward.

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.”

3. What is the difference between the STLC (Software Testing Life Cycle) and SDLC (Software Development Life Cycle)?

SDLC deals with development/coding of the software while STLC deales with validation and verification of the software. This testing is usually done to check the functionality of an application.

4. What is traceability matrix?

The relationship between test cases and requirements is shown with the help of a document. This document is known as a traceability matrix.

5. What is Equivalence partitioning testing?

Equivalence partitioning testing is a software testing technique which divides the application input test data into each partition at least once of equivalent data from which test cases can be derived. By this testing method, it reduces the time required for software testing.

6. What is white box testing and list the types of white box testing?

White box testing technique involves selection of test cases based on an analysis of the internal structure (Code coverage, branches coverage, paths coverage, condition coverage, etc.) of a component or system. It is also known as Code-Based testing or Structural testing. Different types of white box testing are

A. Statement Coverage
B. Decision Coverage

7. What is the difference between static and dynamic testing?

Static testing: During Static testing method, the code is not executed, and it is performed using the software documentation. Dynamic testing: To perform this testing the code is required to be in an executable form. test data into each partition at least once of equivalent data from which test cases can be derived. By this testing method,

8. What Test Plans consists of?

Test design, scope, test strategies, approach are various details that Test plan document consists of.

A.Test case identifier
B. Scope
C. Features to be tested
D. Features not to be tested
E. Test strategy & Test approach
F. Test deliverables
G. Responsibilities
H. Staffing and training
I. Risk and Contingencies

9. What is the difference between UAT (User Acceptance Testing) and System testing?

System Testing: System testing is finding defects when the system undergoes testing as a whole; it is also known as end-to-end testing. In such type of testing, the application suffers from beginning till the end.

UAT: User Acceptance Testing (UAT) involves running a product through a series of specific tests which determines whether the product will meet the needs of its users.

10. Explain what Test Deliverables is?

Test Deliverables are a set of documents, tools and other components that have to be developed and maintained in support of testing.

There are different test deliverables at every phase of the software development lifecycle

1 . Before Testing
2. During Testing
3. After the Testing

11. What is Exploratory Testing?

SDLC deals with development/coding of the software while STLC deales with validation and verification of the software. This testing is usually done to check the functionality of an application.

14. What is traceability matrix?

The relationship between test cases and requirements is shown with the help of a document. This document is known as a traceability matrix.

15. When is used Decision table testing?

Risk-based Testing is the term used for an approach to creating a Test Strategy that is based on prioritizing tests by risk. The basis of the approach is a detailed risk analysis and prioritizing of risks by risk level. Tests to address each risk are then specified, starting with the highest risk first.

Decision table testing is used for testing systems for which the specification takes the form of rules or cause-effect combinations. In a decision table, the inputs are listed in a column, with the outputs in the same column but below the inputs. The remainder of the table explores combinations of inputs to define the outputs produced.

16. What is white box testing and list the types of white box testing?

White box testing technique involves selection of test cases based on an analysis of the internal structure (Code coverage, branches coverage, paths coverage, condition coverage, etc.) of a component or system. It is also known as Code-Based testing or Structural testing. Different types of white box testing are

A. Statement Coverage
B. Decision Coverage

17. What is the difference between static and dynamic testing?

Static testing: During Static testing method, the code is not executed, and it is performed using the software documentation. Dynamic testing: To perform this testing the code is required to be in an executable form. test data into each partition at least once of equivalent data from which test cases can be derived. By this testing method,
Test boundary conditions on, below and above the edges of input and output equivalence classes. For instance, let say a bank application where you can withdraw maximum Rs.20,000 and a minimum of Rs.100, so in boundary value testing we test only the exact boundaries, rather than hitting in the middle. That means we test above the maximum limit and below the minimum limit.
