Question { Accenture, 26464 }

why is testing necessary , explain with some examples?

Answer

Testing is necessary for three reasons
1)To show that the application satisfies customers
needs/expectations.
2)To show that application is fit for purpose
3)To detect defects, so that they can be resolved by
development team.

E.g---->A banking application is delivered to customer with
few bugs in it. End user of bank will suffer some problem
due to bugs in application so he may quit using this bank
also can go for some legal actions. To prevent these kind of
scenarios testing is done. This is very general example.

Question { 4557 }

What is V Model?

Answer

V model is also called as Verification & Validation model as
it have built in verification & validation process at each
phase. It divides the whole testing activity in to two phase
Test design & test execution. It provides guidelines that
testing can be done early in the project dev. Each
development phase has corresponding testing activity.

Question { Crea, 5931 }

What is Verification and Validation ?

Answer

Verification- Provision through objective evidence that
output of a phase in s/w development life cycle meets the
req specified at the start of that phase. Verification looks
for correctness, completeness, consistency. Verification is
a defect prevention activity. Verification mainly applies to
the process used to develop projects. It is also called as
Quality Assurance activity. e.g. different types of reviews.

Validation- Provision through objective that output of a
given phase in S/W development life cycle satisfies the
customer req specified at the start of the phase. Validation
refers to the actual conventional testing we do. Validation
applies to the product. Validation is a defect detection &
correction activity. Black Box testing.

Question { TCS, 10318 }

Client want to execute 1500 test cases and delivery within
three days? But i have 5 resources?
How its possible?

Answer

Simply prioritize test cases, assign each test case a number
derived from priority of test cases & Severity if it fails.
Select all high priority test cases and medium priority test
cases execute them. This is a risk based approach and if
possible inform the stake holders about this situation.

Or Increase Resources (Which is not going to happen in any
case) or work for more than 16 hours for 3 days.

Question { CTS, 9207 }

what is test plan

Answer

Test Plan is nothing but the record of the test process.
A test plan describes & detects how the testing will be
carried out for a product or project.

A document describing the scope,approach, resources and
Schedule of testing activities. It identifies among others
features to be tested, test methodology and test design
techniques to be used. Testing task who will do each task,
any training and staffing needs, Entry Criteria for testing,
Exit criteria for testing, Resumption & Suspension Criteria
for testing. Environmental needs for testing. Risk
associated with testing & any mitigation and contingency
planning.


Test Plan

1)Introduction
2)Objective & Scope
3)Environmental Needs
4)Features to be tested
5)Test Design Tech
6)Testing Schedule
7)Any Training needs
8)Entry Criteria & Exit Criteria
9)Suspension&Resumption Criteria
10)Risk & Contingency Planning
11)Approvals

changes.

Question { IBM, 9364 }

What is test design???

Answer

Test Design refers to the STLC phase in which software
tester will start writing test cases based on any available
SRS doc using test design tech likes BVA, EP, Cause Effect
Graphing, State Transition etc. And if SRS is not available
tester will go with Error Guessing and Exploratory Testing.
