Software Testing Interview Questions & Answers - Learning Mode

Software testing is a process of executing a program or application with the intent of finding the software bugs. It can also be stated as the process of validating and verifying that a software program or application or product: Meets the business and technical requirements that guided it?s design and development. Works as expected. Can be implemented with the same characteristic.

Question: What are the 5 points of the difference between configuration testing and compatibility testing?
What is S-graph

Answer: Compatibility: -The suitability of products, processes or services for use together under specific conditions to fulfill relevancy requirements without causing unacceptable interactions.

Configurability:- The degree to which system design characteristics and planned logistics resources including manpower.It specifies how a System works on different configurations Source:
Question: Have you ever completely tested any part of a product? How?

Answer: It is not possible to test any product completely.

We can test major funcitionalities of the application which are most visible to user and critical parts in the product. Source:
Question: Describe to me when you would consider employing a failure mode and effect analysis.

Answer: failure: failure means "the fact of somenthing expected not being done."

that means the application peforms actions against the requirements.

effect means " a change caused by mething"

effect analysis: since application not perform actions according to the requirements we have to analyse the effect. i.e; where the application deviates from it's requirements and cause for that one. Source:
Question: what is the difference between frs (functional requirement specification) and
srs (software requirement specification) ?

Answer: FRS(Functional Requirement Specification) specifies the flow of work and features of the application

SRS (system)software Requirement Specification means it specifies the S/W and H/W requirements of the application that is to be proposed. Source:
Question: How do you get programmers to build testability support into their code?

Answer: The programers should add comment attached with their code

for a white box tester ... as for products the source code will be changed as per requirements and developers or testers who follow them should understand the logic of code easily
Question: What is meant by butterfly model?

Answer: The Butterfly Model includes algorithms which capture behaviors of triggers, relationships between triggers, and relationships between triggers and defect types. This information is used to isolate and identify opportunities and exposures at the technical level so that explicit actions are easily defined and executed. In addition, these algorithms afford the ability to project the impact of potential exposures on specific triggers, and the activities which own responsibility for them. The links Source:
Question: How do you test if you have minimal or no documentation about the product?

Answer: this type of testing conducting who knows the domain knowledge,frame work,use cases, this type of testing conduting ad-hoc testing,sanity testing Source:
Question: What is difference between Defect Age & Build Interval Period?

Answer: Defect Age : The time of introduction of defect to time of detection. To compute the measurement one assigns a number to each software development life-cycle phase and calculates difference between detection phase with introduction phase (i.e. "analysis" can be assigned a 1, "design" a 2, "coding" a 3, etc. for computation of defect age).

Build interval period: this is the time taken to build newer version of the application and older version.
Question: What are the goals of a performance testing of a web application?

Answer: Performance testing is used for test the application with respect to handle the performance. The main goal behind the performance test on web application is to find out the reason why the application bit slow over access on the network. So it helps to improve the access rate over the network. Source:
Question: How do you test if we have minimal or no documentation about the product?

Question: What are the key challenges of testing?

Answer: Following are some challenges while testing software

1.Requirements are not freezed.

2.Application is not testable.

3.Ego problems.

4.Defect in defect tracking system

5.Miscommunication or no Communication

6.Bug in software development tools.

7.Time pressures Source:
Question: What is globalisation testing?

Answer: The goal of globalization testing is to detect potential problems in application design that could inhibit globalization. It makes sure that the code can handle all international support without breaking functionality that would cause either data loss or display problems. Source:
Question: What is the testing lifecycle and explain each of its phases?

Answer: Testing life cycle

This life cycle is used for standard applications that are built from various custom technologies and follow the normal or standard testing approach. The Application or custom-build Lifecycle and its phases is depicted below:

Test Requirements ? Requirement Specification documents
? Functional Specification documents
? Design Specification documents (use cases, etc)
? Use case Documents
? Test Trace-ability Matrix for identifying Test Coverage
Question: What do you like least about Quality Assurance/Testing?

Answer: Quality Assurance sometimes mitigates the actual Quality Process when there is more documentation required than necessary and this makes the prinicple in carrying the Quality Project obscure.

Developers always dread or dislike Quality due to the un-necessary paper work involved which does nothing to mitigate the quality requirements.
Question: How do you know when the product is tested well enough?


Answer: The gap analysis can be done by tracebility matrix that means tracking down each individual requirements in SRS to various work products. Source:
Question: what is the difference b/w system testing and functional testing


Functional Testing

Testing the features and operational behavior of a product to ensure they correspond to its specifications. Testing that ignores the internal mechanism of a system or component and focuses solely on the outputs generated in response to selected inputs and execution conditions. Functional Testing Black-box type of testing geared to functional requirements of an application. Testers should perform this type of testing.

System Testing
Question: How much interaction with users should testers have, and why?

Answer: gernerally, as a tester we did not have any with the user.
but some times (for ex. when no documentation available ) we may have some interaction with the end users with the permission of our higher officials.
Question: What is Configuration management? Tools used?

Answer: Software configuration management (SCM) is the control, and the recording that are made to the software and documentation throughout the software development cycle (SDLC). SCM covers the tools and processes used to control, coordinate and track code, requirements, documentation, problems, change requests, designs, tools, compilers, libraries, patches and changes made to them, and to keep track of who males the changes.
Tools include Rational ClearCase, Doors, PVCS, CVS and many others.
Question: What is ISO 9000? Have you ever been in an ISO shop?
