Testing /QA Interview Questions And Answers
1) Software
testing: Software testing is a
methodology to find bugs in the software
2) Software Development Life Cycle( SDLC):
4) Positive test
case: - Test to check whether the system do what it is suppose to do.ie,
checking for valid values only.
5) Negative Test
Case: - Test to check whether the system will do what it is not supposed to
do.ie, checking for invalid values.
6) Verification:
It is a set of activity which confirms that the software is created accordance
to the specification
7) Validation:
Is a set of activity which confirms software is created is linked to user
requirement or not
8) Retesting: Failed test case are executed to ensure that defect
is really fixed
9) Regression:
all passed test cases are executed on related module to verify that there is no
injection of new defect to change in one of the module
10) Static: Reviewing artifacts rather than executing code
11) Dynamic:
Testing Perform by executing code by giving i/p and verify o/p
12) Smoke: Is
a simple test condition to ensure that the software is working properly at
gross level so that further testing is done
13) Sanity: It perform to verify whether the application function
according to specification or not
14) Defect:
Defect indicate difference between expected and actual behavior
16) White Box:
It is done by developer. This require knowledge of internal structure and code
of that application
17) Type of white box: 1) Statement 2) Decision3) Condition 4) path
5) loop
18) Black box:
This is done by tester it mainly focus on functional requirement. By providing
set of I/P and observe output.
19) Black box type: 1) BVA 2)
Equivalence class partitioning 3) state transition
20) Alpha: It is done at developer side
under controlled environment. Here developer is present
21) Beta: It
is conducted at one or more customer site in live environment by end user .here
developer is not present
22) Agile testing:
It is testing methodology goes hand in hand to an agile software
development model. Here release are quicker (within 2-3 week) and incremental
are iterative in nature
23) Development
Model:
1) Waterfall:
It is sequential model which process through Requirement->
Design->Coding->Testing
2) Spiral: Divided
into 4 phase 1) Plan2) Design3)
Prototype4) test .In this model software in series of incremental realized. As
we process through iteration more complete versioned is engineered product are
visible. It is useful when user/developer are not cleared about the solution to
developed and needs evaluator approach
3) Agile: Here
release as frequently as every week rather than month and continuous changes in
requirement and welcome to be integrated
24) V-Model:
It is extension of water fall model .here both the aspect quality control and quality assurance are covered. Indicates that testing exits in every phase of SDLC life cycle
25) Test Case: test
case is a set of input and output .here we pass the set of input and observe
the output and system behavior
26) Test Scenario:
Test scenario is a high level definition .here one can write one or more
test cases
Example login
27) Test plan:
Defines purpose, scope, approach, resource, responsibility of testing
activities
Steps: Test Id, Intro, Scope and limitation, Test
Objective, Assumption, Risk analysis, feature to be tested/Not to be, Roles and
Responsibility, schedule, Test environment
