Software Testing:
Why did you choose this Course?* 1. Scope of getting job is very high.
2. No need to depend up on any technologies.3. Testing remains forever4. I want to be consistent through out my life
Why explicitly the s/w companies arerecruited the test engineers?
1. One person cannot efficiently perform two tasks at a time2. Sentimental attachment.
Who can do the course?Any graduate can do this course at this point of time
What exactly we require to get a job?1. Stuff
2. Communication skills
3. Confidence4. Dynamism
Project:Project is some thing that is developed based on the particular
customers requirements and used by that customer only ( E.g.:Marriage laddu)
Product:It is some thing that is developed based on the companies specification and
used by the multiple customers (e.g.: Thirupathi laddu)Quality:Classical definition for quality: - Quality is defined as justification of all therequirements of customer in a product.
NOTE: Quality is not defined in the product; it is defined in the customers mind
Defect: - Defect is defined as deviation from the requirements
Latest definition for quality: - quality is defined as not only the justification of
requirements but also the presence of value (User friendliness)1

Testing:Testing is processes, in which the defects are identified, isolated, subjected
for rectification & ensure that the product is defect free. In order to produce the
quality product in the end and hence customer satisfaction.
Bidding the Project:Bidding the project is defined as request for proposal, estimation and signing
off (Official agreement).
Kick Off Meeting:It is an initial meeting conducted in the software company soon after the
project is signed off. In order to discuss the overview of the project and to select a
project manager for the project.
Usually high level management, Project managers, team managers, quality
managers, team leads and quality leads will be involved in this meeting.
PIN (Project Initiation Note):-It is a mail prepared by the project manager and sent to the CEO of the soft
ware company in order to get the permission to start the project developments.
Software Development Life Cycle (SDLC):-SDLC contains six phases they are
1. Initial phase or requirements phase.
2. Analysis phase
3. Design phase
4. Coding Phase
5. Testing Phase
6. Delivery & Maintenance Phase.
I. Initial Phase or Requirements Phase :
(a) Tasks: Interaction with the customer and gathering the requirements.
(b) Roles: Business Analyst (B.A), Engagement Manager (E.M)
Process: First of all the business analyst will take an appointment from thecustomer, collects the templates from the company, meets the customer on
appointed day, gathers the requirements with the help of template and comes back
to the company with the requirements documents.
Once the requirement document has come to the company the
engagement manager will check whether the customer gives any extra requirements
or confused requirements. In case of extra requirements he deals the excess cost of

the project. In case of confused requirements he is the responsible for prototype
demonstration and gathering the clear requirements.
Proof: The proof document of this phase is Requirements Document. This iscalled with different names in different companies.
1. FRS (Functional Requirements Specification)
2. CRS (Customer Requirement Specification)
3. URS (User Requirement Specification)
4. BDD (Business Design Document)
5. BD (Business Document)
6. BRS (Business Requirement Specification)
Some companies may maintain the over all business flow information in one
document and the detailed functional requirement information in the otherdocument
Templates: It is a pre defined format, which contains the predefined fields, andused for preparing a document in an easy, comfort and perfect manner.
Prototype: -Defined as a roughly & Rapidly developed model which is used fordemonstrating to the client, In order to gather the clear requirements and to win the
confidence of a customer.
II. Analysis Phase:
(a) Tasks:
1. Feasibility Study
2. Tentative planning
3. Technology Selection
4. Requirement Analysis
(b) Roles: System Analyst, Project Manager, and Team Manager.
Process
1. Feasibility Study: - It is detailed study of the requirements in order tocheck weather the requirements are possible or not.
2. Tentative Planning: In this section the resource planning and the timeplanning (scheduling) is done temporarily.

3. Technology Selection: - The list of all the technologies that are requiredto accomplish this project. Successfully will be analyzed and listed out in this
section.
4. Requirement Analysis: - The list of all the requirements that arerequired to accomplish this project. Successfully will be analyzed and listed
out here in this section.
SRS- System requirement specification
Proof: - The proof of this phase is System Requirement Specification.
III. Design Phase: -
Tasks:
1. High level designing
2. Low level designing
Roles: High-level designing is done by the chief Architect & Low leveldesigning is done by the Technical Lead
Process: The Chief architect will be drawing some diagrams using unifiedmodeling language in order to divide the whole project in to modules.
The Technical lead will also draw some diagrams in order to divide the
modules in to sub modules.
The technical lead will also develop the PSEUDO code in order to make
developers comfortable while developing the actual code.
Proof: The proof document of this phase is Technical design document.
IV. Coding phase:
(a) Task: Developing or Programming
(b) Roles: Developers or Programmers
Process: Developers will develop the actual code by using the technical designdocument as well as following the coding standards like Proper indentation, color
coding, proper commenting and etc..,
Proof: The proof document of this phase is source code Document.
E.g.: The programmer will develop some programs every one will develop his
program in different colors but the soft ware companies will ask the developers to
develop the program according to the company standards using proper color,
coding, commenting. So as to understand it easily.4

V. Testing Phase:
(a) Task: Testing
(b) Roles: Test engineers
Process:
1. First of all the test engineers will collect the requirements
document and try to understand all the requirements
2. While understanding it at all they get any doubts they will
list out all of them in a review report.
3. They will send the review report to the author of therequirements document for clarifications.
4. Once the clarifications are given and after understanding
all the requirements clearly, they will take the test case
template and writes the test cases.
5. Once the first build is released then they will execute the
test cases
6. If at all any defects are found. They will list out all of them
in a defect profile template then
7. They will sent the defect profile document to the
development department and then will be waiting for the
next build to be released.
8. Once the next build is released then they re-execute the test
cases.
9. If at all any defects are found they will update the profile
document and sent it to the development department and
will be waiting fro the next build to be released .
10. This process continuous till the product is defect free.
Proof: The proof of the testing phase is Quality Product.
Test Case: (def) Test case is an idea of a test engineer based on the customersrequirements in order to test a particular feature or a function.

VI. Delivery & Maintenance Phase:
Delivery:
(a) Task: - Installing the application in the clients environment
(b) Rolls: -Deployment engineer or Senior test engineers.
Process: - The senior test engineer or deployment engineer will be going to theclients place and install the application in their environment with the help of the
guidelines provide in the deployment document.
Maintenance:
After delivering the software while using if at all any problem occurs
then that problem becomes a task, based on that problem corresponding roles will
be appointed, the roles will defined the process and solve that problem.
Some clients may request for the continuous maintenance in such situations a
group of people from the software company will be continuously working on the
clients place and taking care of the soft ware.
************************^^^^^^^^^^^^^^^^^^^************************
Where exactly the testing comes in to picture?Which sort of testing you are expecting?How many sorts of testing are there?There are two sorts of testing.
1. UN-Conventional testing
2. Conventional testing
1.UN-Conventional Testing: -Unconventional testing is a sort of testing done bythe quality assurance people, in which they test each and every out come document
right from initial phase of the SDLC (Software development life cycle)
2.Conventional Testing: It is sort of testing done by the test engineers on theapplication in the testing phase of SDLC.

Testing Methodology or Testing techniques:There are three methods of testing
(a) Black-Box Testing
(b) White-Box Testing
(a) Grey-Box Testing
(a) Black-Box Testing: If one performs testing only on the functional part of
an application with out having any structural knowledge then that method oftesting is known as Black-Box testing, usually the test engineers perform it.
(b) White-Box Testing: If one performs testing on the structural part of anapplication then that method of testing is known as white box testing, usually
the developers or white box testers perform it.
(c) Grey-Box Testing: If one performs testing on both the functional part aswell as the structural part of an application then that method of testing as
known as grey box testing using the test engineers who have structural
knowledge will perform gray- box testing.
Levels of Testing:There are five levels of testing
1. Unit Level Testing
2. Module Level Testing
3. Integration Level Testing
4. System Level Testing
5. User Acceptance Testing (U.A.T)
1.Unit Level Testing: -
It is a level of testing in which one will perform testing on the units. It is a
white box testing and usually developers or white box testers will perform.

2.Module Level Testing: -
Module: Module is defined as a group of related functionalities to perform a majortask
It is a level of testing in which one will perform testing on the modules. It is a black
box testing and usually test engineers perform it.
3.Integration Level Testing: -
It is a level of testing in which the developers will develop some interfaces to
integrate the modules and test whether the interfaces are working fine or not. It is a
white box testing usually developers or white box tasters perform.
The developers may follow one of the following approaches while integrating
the modules.
1.Top-down approach
2.Bottom up approach
3.Hybrid or Sandwich approach
4.Big-bang approach
1.Top-down approach: - In this approach one will develop the parent modulesfirst and then integrate them with the related child modules
2.Bottom-up approach: - In this approach one will develop the child modulesfirst and integrate them to the parent modules
3.Hybrid approach Or Sandwich approach:- This is a mixed approach ofboth the top down and bottom up approaches
4.Big bang approach:-In this approach one will wait till all the modules areready and finally they will integrate all the modules at a time
STUB: - While integrating the modules in top down approach if at all anymandatory module is missing (not completed) then that module is replace with
a temporary program known as STUB
DRIVER: -While integrating the modules in bottom up approach. If at all anymandatory module is missing (not completed) then that module is replaced with atemporary program known as DRIVER
4.System Level Testing:
It is a level of testing in which one will install the complete application in to
the environment and then perform testing on it. At this level different types of
testing will be done one among those is system integration testing.

Page 9
5.System integration Testing: -
It is a type of testing in which once the complete application is developed one
will perform an action at one module and checks for the reflections at the
corresponding modules. It is a black box testing and usually test engineers
perform.
6.User- Acceptance Testing: -
It is the level of testing in which one will perform the same system testing in
the presence of the user in order to make him accept the application. It is a black
box testing and usually Test engineer performs it.
Environment: - Environment is a combination of three layers (e.g.: Yahoo)
a. Presentation layer
b. Business layer
c. Data base Layer
System: The application installed in to an environment combinable called as system.
a. Presentation Logic: The logic that is used for viewing application isknown as presentation logic
b. Business Logic: - The logic that is used for performing the operations onthe application is known as business logic.
c. Data Base Logic: - The logic that is used for sharing and retrieving thedata is known as database logic.
Types of Environment: - There are Four types of environments
a. Stand alone environment or One-tier environment
b. Client server environment or Two-tier Architecture

Testing part to be continued.
1.Build Acceptance Testing Or Build Verification Testing Or
Sanity Testing: -
It is a types of testing in which one will conduct over all testing on the
released build in order to check whether it is proper for further detailed testing or
not. Even some companies call it as smoke testing, but some companies says that
just before releasing the build the developers will conduct the overall testing on the
build that is known as smoke testing and once the build is released what ever thetest engineers do in order to accept the build is known as B.A.T or B.V.T or Sanity
Testing.
2.Regression Testing: -
It is a type of testing in which one will perform testing on the already tested
functionalities again and again.
It is usually done in two scenarios.
1. Whenever the testers has raised the defects, rectified by the developers and next
build is released to the testing department then the test engineers will test the
defect functionality as well as the related functionality once again.
2. When ever some new features are incorporated by the developers, next build is
released to the testing department then the test engineers will once again test the
related functionalities of the new features in order to confirm that they are
working same as previous.
Note: - Testing the new functionalities for the first time is known as new testingbut not Regression Testing.

3.Re-Testing: -
It is a type of testing in which one will test the same functionality again and
again with different sets of values in order to come to a conclusion whether it is
working or not.
4. - Testing (Alpha Testing): -It is a type of user acceptance testing in which the test engineers will test the
application in our company, in the presence of the customer.
Advantage: - If at all any defects are found then there is a chance of rectifyingthem immediately.
5. -Testing (Beta): -It is a type of user acceptance testing done in the clients
place either by the end-users or by the third party testing experts before actual
implementation.
Drawback: If at all any defects are found then there is no chance of rectifying them
immediately.
6. Static Testing: -
It is a type of testing in which one will perform testing on the application or
application related factors with out performing any action.
Eg:- Documentary testing, GUI testing, Code reviews and etc.,
7. Dynamic Testing: -
It is a type of testing in which one will perform in the application or its
related factors by doing some actions
Eg: - Functionality testing.
8.Installation Testing: -
It is a type of testing in which one will install the application in to the
environment by following the guide lines provided in the installation document and
if the installation is successful then he will come a conclusion that the given guide
lines are correct other wise he will come to a conclusion that the given guidelines are
not correct.

9.Compatibility Testing: -
It is a type of testing in which one may have to deploy the application in to
the multiple number of environments prepared with different combinations of
environmental components in order to check whether the application is compatible
with all that environments. This type of testing is usually done to products.
10. Monkey Testing: -
It is a type of testing in which one will perform abnormal action on the
application intentionally in order to check the stability of the application.
11.Usability Testing: -
It is a type of testing in which one will check whether the application is user
friendly or not and it can be comfortably used by the end user or not.
12. Exploratory Testing: -
It is a type of testing in which one will (Domain Experts) perform testing on
the application with out having the knowledge of requirements but by exploring the
functionality.
13.End-To- End Testing: -
It is a type of testing in which one will perform testing on all the end- to-end
scenarios of the application.
14.Port Testing:-
It is a type of testing in which one will deploy the application in to the clients
environment and check whether it is compatible with that environment or not.
15.Reliability Testing: -It is a type of testing in which one will perform testing on the application
continuously for long period of time in order to check the stability of the application
16.Security Testing: -It is a type of testing in which one will concentrate on the following areas of
the application
a). Authentication Testingb). Direct URL Testing (Uniform Resource Location)c). Fire Wall Leakage Testing.

(a) Authentication Testing: -It is a type of testing in which one will enter different combinations of user
names and passwords and try to access the home page in order to check whether
only the authorized persons are accessing the application or not.
(b) Direct URL Testing: -It is a type of testing in which one will enter the URL of an unauthorized
page directly in the browser and try to access that page in order to check whether it
is been accessed or not.
(c) Firewall Leakage Testing : -It is a type of testing in which one will enter as one level of user and try to
access the other level of unauthorized pages in order to check whether the firewalls
are working properly or not.
17. Mutation Testing: -
It is a type of testing in which one will perform testing on something by doing
some changes to it.
18. ADHOC Testing: -
It is a type of testing in which one will perform testing on the application inhis own style after understanding the requirements clearly.

Types Of Test Cases:There are Two types of test cases if we see broadly they are:
1. GUI Test Cases2. Functional Test Cases
The Functional cases are further divided in to Two types
(a) Positive Test Cases,(b) Negative Test Cases.
Guide Lines fo developing the GUI Test Cases:
Check for the availability of all the objects
Check for the alignments of all the objects up on customer requirements
Check for the consistency of all the objects
Check for the spellings and grammar
Apart from the above guide lines any thing else that can be tested just by
looking without doing any actions will fall under GUI test cases
Guide Lines for Positive Test Cases:

Page 32
A test engineer should have positive mind set up
He should consider the positive flow of the application
He should use only the valid Input
Guidelines for developing Negative Test Cases:
A test engineer should have negative mind set up
He should consider the negative flow of the application
He should use at least one invalid input per a set of data
Test Case Template: -
(a) Test Objective
(b) Test scenario
(c) Test procedure(d) Test Data

A test Engineer will do the following during the test execution
1. He will perform the action that is described in the description column
2. He will observe the actual behavior under the actual value column.
3. He will document the observed value under the actual value column.
In this phase the test engineer will compare the expected values with the actual
values and if both are matched they will document the result as pass other wise they
will document the result as fail.
Bug Tracking is a process in which the defects are identified, Isolated and managed

Priority: -Priority defines the sequence in which the defects has to be rectified. It is
classified in to four types
1.Critical (Pri1) or P1 or 1
2.High (Pri2) or P2 or 2
3.Medium (Pri3) or P3 or 3
4.Low (Pri4) or P4 or 4Usually the Fatal defects are given critical priority, Major defects are given
High priority, Minor defects are given Medium Priority and suggestions are given
Low Priority, But depending up on the situations the priority will be changing.
I - Case:Low severity-High Priority Case: -
Up on customer visit to the company all the look and feel defects are
given highest priority.
II - Case:High severity Low Priority Case: -
When ever 80% of the application is released to testing department as
20% is missing the test engineers will treat them as Fatal defect but the development
lead will give least priority for those defects as features are under development.

Status: -
New: - When ever the defect is found for the first time the test engineer will set the
status as New.
Open: -When ever the developer accepts the raised defect then he will set the status
as open.
Fixed for verification Or Fixed for rectified: - When ever the developer rectifies theraised defect then he will change the status to fixed.
Re open and Closed: -When ever the defects are rectified, next build is released to
the testing dept then the test engineers will check whether the defects are rectified
properly or not. If the defect is rectified properly then the test engineer will set the
status as Closed. If the defect is not rectified properly then the test engineer will
set the status as Re open.
Hold: - When ever the developer is confused to accept or reject the defect then he
will set the status of the defect as hold.
Testers Error or Testers Mistake Or Rejected: - When ever the developer is
confirmed it is not at all a defect then he will set the status of the defect as
Rejected.
As Per Design: - When ever the test engineer is not aware of new requirements and
if he raises defects related to the new features then the developer will set the status
As Per Design.
