1. What is Software Testing?
Ans. Testing involves operation of a system or application under controlled
conditions and evaluating the results. The controlled conditions should include
both normal and abnormal conditions.
Testing is a process of executing a program with the intend of finding the
errors.
2. What is the Purpose of Testing?
Ans. The purpose of testing is
1· To uncover hidden errors
2· To achieve the maximum usability of the system
3· To Demonstrate expected performance of the system
3. What types of testing do testers perform?
Ans. Two types of testing 1.White Box Testing 2.Black Box Testing.
4. What is the Outcome of Testing?
Ans. The outcome of testing will be a stable application which meets the customer
Req's.
5. What kind of testing have you done?
Ans. Usability, Functionality, System testing, regression testing, UAT
(it depends on the person).
6. What is the need for testing?
Ans. The Primary need is to match requirements get satisfied with the
functionality
and also to answer two questions
1· Whether the system is doing what it supposes to do?
2· Whether the system is not performing what it is not suppose to do?
7. What are the entry criteria for Functionality and Performance testing?
Ans. Entry criteria for Functionality testing is Functional Specification /BRS
(CRS)/User Manual. An integrated application, Stable for testing.
Entry criteria for Performance testing is successfully of functional testing,
once all the requirements related to functional are covered and tested, and
approved or validated.
8. What is test metrics?
A. The objective of Test Metrics is to capture the planned and actual quantities the effort, time and resources required to complete all the phases of Testing of the SW Project.
9. Why do you go for White box testing, when Black box testing is available?
A. A benchmark that certifies Commercial (Business) aspects and also functional
(technical) aspects is objectives of black box testing. Here loops, structures,
arrays, conditions, files, etc are very micro level but they arc Basement for
any application, So White box takes these things in Macro level and test these
things Even though Black box testing is available, we should go for White box testing
also, to check the correctness of code and for integrating the modules.
10. What are the entry criteria for Automation testing?
A. Application should be stable. Clear Design and Flow of the application is
needed.
11. When to start and Stop Testing?
A. This can be difficult to determine. Many modern software applications are so
complex, and run in such an interdependent environment, that complete testing
can never be done.
Common factors in deciding when to stop are:
Deadlines (release deadlines, testing deadlines, etc.)
Test cases completed with certain percentage passed
Test budget depleted
Coverage of code/functionality/requirements reaches a specified point
Bug rate falls below a certain level
Beta or alpha testing period ends
12.What is Quality?
A. It ensures that software is a Bug free, delivered in time, within budget,
meets customer requirements and maintainable. Quality standards are different
in various areas like accounting department might define quality in terms of
Profit.
13. What is Baseline document?
A. The review and approved document is called as baseline document (i.e.) Test
plan, SRS.
14. What is verification?
A. To check whether we are developing the right product according to the
customer requirements r not .It is a static process.
15. What is validation?
A. To check whether we have developed the product according to the customer
requirements r not. It is a Dynamic process.
16. What is quality assurance?
A. Quality Assurance measures the quality of processes used to create a quality
product.
1.It is a system of management activities.
2.It is a preventive process.
3.It applies for entire life cycle.
4.Deals with Process.
17.What is quality control?
A. Quality control measures the quality of a product
1.It is a specific part of the QA procedure.
2.It is a corrective process.
3.It applies for particular product.
4.Deals with the product.
18.What is SDLC and TDLC?
A. Software development life cycle(SDLC) is life cycle of a project from
starting to ending of the project.
1.Requiremnts Specification. 2.Analysis
3.Design 4.Coding
5.Testing 6.User acceptance test(UAT)
7.Maintainance
Software Test Life Cycle(STLC) is a life cycle of the testing process.
1.Requiremnts Specification. 2.Planning
3.Test case Design. 4.Execution
5.Bug Reporting. 6.Maintainance
19.What are the Qualities of a Tester?
A. Tester should have qualities like
1.ability to break 2.paitence 3.communication
4.Presentation 5.team work. 6.negative thinking with good judgment skills
20.When to start and Stop Testing?
A. repeat
21.What are the various levels of testing?
A. The various levels of testing like
1· Ad - Hoc testing
2. Sanity Test
3. Regression Testing
4. Functional testing
5· Web Testing
22.What are the types of testing you know and you experienced?
A. I am experienced in Black Box testing.
24.After completing testing, what would you deliver to the client?
A. It is depend upon what you have specified in the test plan document.
the contents delivers to the clients is nothing but Test Deliverables.
1.Test plan document 2.Master test case document 3.Test summary Report.
4.Defect Reports.
25.What is a Test Bed?
A. Test bed means under what test environment (Hardware, software set up) the
application will run smoothly.
27.Why do you go for Test Bed?
A. We will prepare test bed bcoz first we need to identify under which
environment (Hardware,software) the application will run smoothly,then
only we can run the application smoothly without any intereptions.
28.What is Severity and Priority and who will decide what?
A. Severity and priority will be assigned for a particular bug to know the
importance of the bug.
Severity:How sevierly the bug is effecting the application.
Priority:Informing to the developer which bug to be fix first.
29.Can Automation testing replace manual testing? If it so, how?
A. Yes,it can be done manually when the project is small,having more time.
we can test with minimum number of users.
30.What is a test case?
A. A test case is a document that describes an input, action, or event and an
expected response, to determine if a feature of an application is working
correctly.
31.What is a test condition?
A. The condition required to test a feature.(pre condition)
32.What is the test script?
A. Test script is the script which is generated by an automation tool while
recording a application features
33.What is the test data?
A. Test data means the input data (valid, invalid data) giving to check the
feature of an application is working correctly.
34.What is an Inconsistent bug?
A. the bug which is occurring
35.What is the difference between Re-testing and Regression testing?
A Re-testing:Executing the same test case by giving the no. of inputs on same
build.
Regression testing:Executing the same test case on a modified build.
36.What are the different types of testing techniques?
A. 1.white Box testing 2.Black Box testing.
37.What are the different types of test case techniques?
A. 1.Equilance Partition. 2.Boundary Value Analysis. 3.Error guesing.
39.Differentiate Test bed and Test Environment?
A. Both are same.
40.What ifs the difference between defect, error, bug, failure, fault?
A. Defect: While executing the test case if u found any mismatch, then u will
report it to the development team, that is called defect.
Bug: Once the developer accepts your defect, then it is called as a bug.
Error: it may be program error or syntax error.
42. What is the difference between White & Black Box Testing?
A. White Box Testing: Based on the knowledge of the internal logic of an
application's code.Tests are based on coverage of code statements, branches,
paths, conditions.
Black Box testing:- not based on any knowledge of internal design or code.
Tests are based on requirements and functionality.
43.What is the difference between Quality Assurance and Quality Control?
A. Refer Question no.16 & 17
Quality Assurance measures the quality of processes used to create a
quality product. Quality control measures the quality of the product.
44.What is the difference between Testing and debugging?
A. The Purpose of testing is to show the program has bugs.
The Purpose of debugging is find the error/ misconception that led to failure
and implement program changes that correct the error.
45.What is the difference between bug and defect?
A. Defect:While executing the test case if u found any mismatch,the u will
report it to the development team,that is called defect.
