QUESTION

WHICH METHODOLOGY
DO YOU FOLLOW IN
YOUR TEST CASE?
Phase Containment is consolidating
QA into each of the stages of SDLC.
It brings about Defect Prevention. In
the event that QA group performs
Design Review, Requirements
Review, and Code Review, errors
would be not many when a real
application is tested. That implies we
have averted numerous errors by
performing reviews at each phase of
SDLC.

Alpha testing is finished by the
in-house testers and engineers
who built up the product. In some
cases, alpha testing is completed
by the customer or outsourcing
group with the presence of
testers or developers.
Beta testing is performed by a
set number of end clients before
delivery. Normally, it is done in
the customer place.
WhatisAlphaTesting
andBetaTesting?

It is done to examine whether
the individual module or unit of
the source code is working
legitimately. It is performed by
the software developers in
developer’s environment. Unit
Testing is additionally known as
Component Testing or Module
Testing.
WhatisUnitTesting?

This type of testing is used to
detect if a set of the test case or
test data is useful by
intentionally presenting different
code changes (bugs) and
retesting with real test
cases/data to decide whether
the bugs are discovered.
WhatisMutation
testing?

Black box testing is the product
testing technique which is
applied to test the product
without distinguishing the
internal structure of program or
code. This testing is typically
done to validate the
functionality of an application.
WhatisBlackBox
Testing?

Test cases are not generally
straightforward and QA
Engineers should follow up on
their own judgment. They have to
feel great with ambiguity.

WHAT ARE QUALITY
CONTROL AND QUALITY
ASSURANCE?
Quality Assurance includes in process-
oriented practices. It guarantees the
counteractive action of bugs in the
process utilized to make software
application. So, the bugs don’t emerge
when the software application is being
produced.
Quality Control includes product-
oriented practices. It administers the
code or program to distinguish the
bugs in the software application.

WHAT IS AGILE
TESTING?
Agile testing is a type of software
testing practice that takes after the
standards of an agile software
development. It is an iterative
program development procedure
where necessities continue changing
according to the client needs. Testing
is done in parallel with the
advancement of an iterative model.
Test group gets frequent code
changes from the dev group for
testing a system.

IN INCREMENTAL
TESTING WHAT ARE
STUBS AND DRIVERS?
The two stubs and drivers are a
component of incremental testing. In
incremental testing, there are two
methodologies to be specifically
bottom-up and top-down methods.
Drivers are utilized as a part of
bottom-up testing and stub is utilized
for the top-down method. With a
specific goal to test the principle
module, a stub is utilized, which is a
dummy program or code.

WHAT IS PERFORMANCE
TESTING?
This kind of testing decides or
approves the speed, versatility, or
durability qualities of the application
or system under test. Execution is
concerned about accomplishing
response times, resource usage levels,
and throughput that meet the
execution targets for the product or
project.

WHAT IS FUZZ TESTING
AND WHEN WILL YOU
USE IT?
Fuzz testing is used to recognize
security loopholes and coding mistakes
in the product. In this method, random
data is added to the application trying
to crash the system. In the event that
vulnerability continues, a device
called fuzz tester is utilized to decide
possible causes. This strategy is more
helpful for greater projects yet just
recognizes a major mistake.

WHAT OUGHT TO BE
DONE AFTER A BUG IS
FOUND?
Configuration administration covers
the procedures used to control,
facilitate, and track: code,
prerequisites, documentation, issues,
change demands, designs,
compilers/tools/libraries/patches,
alterations made to them, and who
rolls out the improvements.

WHAT IS ERROR
SEEDING?
Error seeding is a procedure of
intendedly including known errors in
software to recognize the rate of
error location. It helps during
evaluating of the tester aptitudes of
discovering bugs and furthermore to
know the capacity of the application
i.e. how well the application is working
when it has errors.

WHAT IS POSITIVE AND
NEGATIVE TESTING?
A positive testing is a point at which
you put in a valid info and anticipate
that some activity will be finished as
per the specification.
A negative test is a point at which you
put in an invalid information and gets
errors.

WHAT IS EQUIVALENCE
CLASS PARTITION?
In equivalenceclass partition, inputs to
the system or product are separated
into groups that are required to
display like behavior, so they are
probably going to be proposed
similarly. Thus, choosing one input
from each group for designing the test
case.

WHAT IS BUG LEAKAGE?
A bug which is really missed by the
testing group while testing and the
build was discharged to the
Production. In case that now that bug
was found by the end user then we
refer to it as Bug Leakage.
