What is software?
• A Software is a collection of computer programs that helps us to perform a task.
• Types of Software:
• System software
Ex: Device drivers, OS, Servers, Utilities, etc.
• Programming software
Ex: compilers, debuggers, interpreters, etc.
• Application software
Ex: industrial automation, business software, games, telecoms, etc.

Product Vs Project
• If software application is developed for specific customer
requirement then it is called Project.
• If software application is developed for multiple customers
requirement then it called Product.

What is Software Testing?
• Software Testing is a part of software development process.
• Software Testing is an activity to detect and identify the defects in
the software.
• The objective of testing is to release quality product to the client.

Why do we need testing?
• Ensure that software is bug free.
• Ensure that system meets customer requirements and software
specifications.
• Ensure that system meets end user expectations.
• Fixing the bugs identified after release is expensive.

Software Quality
• Quality: Quality is defined as justification of all the requirements of a
customer in a product.
• Note: Quality is not defined in the product. It is defined in the customer`s
mind.
• Quality software is reasonably
• Bug-free.
• Delivered on time.
• Within budget.
• Meets requirements and/or expectations.
• Maintainable.

Error, bug & failure
• Error: Any incorrect human action that produces a problem in the system is called
an error.
• Defect/Bug: Deviation from the expected behavior to the actual behavior of the
system is called defect.
• Failure: The deviation identified by end-user while using the system is called a
failure.

Why there are bugs in software?
• Miscommunication or no communication
• Software complexity
• Programming errors
• Changing requirements
• Lack of skilled testers
Etc..

Software Development Life Cycle (SDLC)
• SDLC, Software Development Life Cycle is a process used by software
industry to design, develop and test high quality software's.
• The SDLC aims to produce a high quality software that meets
customer expectations.

SDLC Models
• Waterfall Model
• Incremental Model
• Spiral Model
• V- Model
• Agile Model

QA Vs QC/QE
• QA is Process related.
• QC is the actual testing of the software.
• QA focuses on building in quality.
• QC focuses on testing for quality.
• QA is preventing defects.
• QC is detecting defects.
• QA is process oriented.
• QC is Product oriented.
• QA for entire life cycle.
• QC for testing part in SDLC

Verification V/S Validation
• Verification checks whether we are building the right system.
• Verification typically involves.
• Reviews
• Walkthroughs
• Inspections
• Validation checks whether we are building the system right.
• Takes place after verifications are completed.
• Validation typically involves actual testing.
• System Testing

Static V/S Dynamic Testing
• Static testing is an approach to test project documents in the form of Reviews,
Walkthroughs and Inspections.
• Dynamic testing is an approach to test the actual software by giving inputs and
observing results.

Review, Walkthrough & Inspection
• Reviews:
• Conducts on documents to ensure correctness and completeness.
• Example:
 Requirement Reviews
 Design Reviews
 Code Reviews
 Test plan reviews
 Test cases reviews etc.

• Walkthroughs:
• It is a formal review and we can discuss/raise the issues at
peer level.
• Also walkthrough does not have minutes of the meet. It can
happen at any time and conclude just like that no schedule as
such.

• Inspections:
• Its a formal approach to the requirements schedule.
• At least 3- 8 people will sit in the meeting 1- reader 2-writer 3-
moderator plus concerned.
• Inspection will have a proper schedule which will be intimated
via email to the concerned developer/tester.

Levels of Software Testing
• Unit Testing
• Integration Testing
• System Testing
• User Acceptance Testing(UAT)

manualtesting-170218090020 (1).pdf

Unit Testing
• A unit is the smallest testable part of software. It usually has one
or a few inputs and usually a single output.
• Unit testing conducts on a single program or single module.
• Unit Testing is white box testing technique.
• Unit testing is conducted by the developers.
• Unit testing techniques:
• Basis path testing
• Control structure testing
• Conditional coverage
• Loops Coverage
• Mutation Testing

Integration Testing
• In Integration Testing, individual software modules are integrated
logically and tested as a group.
• Integration testing focuses on checking data communication
amongst these modules.
• Integrated Testing is white box testing technique.
• Integrated testing is conducted by the developers.
• Approaches:
• Top Down Approach
• Bottom Up Approach
• Sandwich Approach(Hybrid)

• Stub: Is called by the Module under Test.
• Driver: Calls the Module to be tested.

Bottom-Up Integration
• In the bottom up strategy, each module at lower levels is tested with higher
modules until all modules are tested. It takes help of Drivers for testing.

Top down Integration
• In Top to down approach, testing takes place from top to down
following the control flow of the software system.
• Takes help of stubs for testing.

System Testing
• Testing over all functionality of the application with respective client
requirements.
• It is a black box testing technique.
• This testing is conducted by testing team.
• Before conducting system testing we should know the requirements.
• System Testing focusses on below aspects.
• User Interface Testing (GUI)
• Functional Testing
• Non-Functional Testing
• Usability Testing

User Acceptance Testing
• After completion of system testing UAT team conducts
acceptance testing in two levels.
• Alpha testing
• Beta testing

Testing Methodologies
• White box Testing
• Black box Testing
• Grey box Testing

White Box Testing
• White Box Testing conducts on internal logic of the programs.
• Programming Skills are required.
• Ex: Unit Testing & Integration Testing

Block Box Testing
• Testing conducts on functionality of the application whether it is
working according to customer requirements or not.
• Ex: System Testing & UAT Testing

Grey Box Testing
• Both combination of white box and black box testing.
• Ex: Database Testing

Black Box Testing Types
• GUI Testing
• Usability Testing
• Functional Testing

What is GUI?
• There are two types of interfaces in a computer application.
• Command Line Interface is where you type text and computer
responds to that command.
• GUI stands for Graphical User Interface where you interact
with the computer using images rather than text.

GUI Testing
• Graphical User Interface (GUI) testing is the process of testing the system’s GUI.
• GUI testing involves checking the screens with the controls like menus, buttons,
icons, and all types of bars – tool bar, menu bar, dialog boxes and windows etc.
• During GUI Testing Test Engineers validates user interface of the application as
following aspects:
• Look & Feel
• Easy to use
• Navigations & Shortcut keys
• GUI Objects:
• Window, Dialog Box, Push Button, Radio Button, Radio Group, Tool bar, Edit Box, Text Box,
Check Box, List Box, Drop down Box, Combo Box, Tab, Tree view, progress bar, Table, Scroll
bar Etc.

Check list for GUI Testing
• It checks if all the basic elements are available in the page or not.
• It checks the spelling of the objects.
• It checks alignments of the objects.
• It checks content display in web pages.
• It checks if the mandatory fields are highlights or not.
• It checks consistency in background color and color font type and
fond size etc.

Usability Testing
• During this testing validates application provided context
sensitive help or not to the user.
• Checks how easily the end users are able to understand
and operate the application is called usability testing.

• Software testing performed without proper planning and
documentation.
• Testing is carried out with the knowledge of the tester about the
application and the tester tests randomly without following the
specifications/requirements.
• Monkey Testing:
• Test the functionality randomly without knowledge of application and
test cases is called Monkey Testing.

Testing Terminology cont…
• Re- Testing:
• Testing functionality repetitively is called re-testing.
• Re-testing gets introduced in the following two scenarios.
• Testing is functionality with multiple inputs to confirm the business validation are
implemented (or) not.
• Testing functionality in the modified build is to confirm the bug fixers are made correctly (or)
not.
• Regression Testing:
• It is a process of identifying various features in the modified build where there is a chance of
getting side-effects and retesting these features.
• The new functionalities added to the existing system (or) modifications made to the existing
system .It must be noted that a bug fixer might introduce side-effects and a regression testing is
helpful to identify these side effects.

• Sanity Testing:
• This is a basic functional testing conducted by test engineer
whenever receive build from development team.
• Smoke Testing:
• This is also basic functional testing conducted by developer or tester
before releasing the build to the next cycle.

• End to End Testing:
• Testing the overall functionalities of the system including the data
integration among all the modules is called end-to-end testing.
• Exploratory Testing:
• Exploring the application and understanding the functionalities
adding or modifying the existing test cases for better testing is called
exploratory testing.

• Globalization Testing (or) Internationalization Testing(I18N):
• Checks if the application has a provision of setting and changing
languages date and time format and currency etc. If it is designed for
global users, it is called globalization testing.
• Localization Testing:
• Checks default languages currency date and time format etc. If it is
designed for a particular locality of users is called Localization
testing.

• Positive Testing (+ve ):
• Testing conducted on the application in a positive approach to determine what
system is supposed to do is called a positive testing.
• Positive testing helps in checking if the customer requirements are justifying the
application or not.
• Negative Testing ( -ve):
• Testing a software application with a negative perception to check what system is
not supposed to do is called negative testing.

Software Testing Life Cycle (STLC)

• During Test Execution Test engineers are reporting mismatches as defects
to developers through templates or using tools.
• Defect Reporting Tools:
• Clear Quest
• DevTrack
• Jira
• Quality Center
• Bug Jilla etc.

Defect Report Contents
• Defect_ID - Unique identification number for the defect.
• Defect Description - Detailed description of the defect including information about the module in which defect was found.
• Version - Version of the application in which defect was found.
• Steps - Detailed steps along with screenshots with which the developer can reproduce the defects.
• Date Raised - Date when the defect is raised
• Reference- where in you Provide reference to the documents like . requirements, design, architecture or may be even
screenshots of the error to help understand the defect
• Detected By - Name/ID of the tester who raised the defect

• Fixed by - Name/ID of the developer who fixed it
• Date Closed - Date when the defect is closed
• Severity which describes the impact of the defect on the application
• Priority which is related to defect fixing urgency. Severity Priority could be High/Medium/Low based on the impact urgency
at which the defect should be fixed respectively

Defect Classification

Defect Severity
• Severity describes the seriousness of defect.
• In software testing, defect severity can be defined as the degree of impact
a defect has on the development or operation of a component application
being tested.
• Defect severity can be categorized into four class
• Critical: This defect indicates complete shut-down of the process, nothing can
proceed further
• High: It is a highly severe defect and collapse the system. However, certain parts of
the system remain functional
• Medium: It cause some undesirable behavior, but the system is still functional
• Low: It won't cause any major break-down of the system

Defect Priority
• Priority describes the importance of defect.
• Defect Priority states the order in which a defect should be fixed. Higher
the priority the sooner the defect should be resolved.
• Defect priority can be categorized into three class
• P1 (High) : The defect must be resolved as soon as possible as it affects the
system severely and cannot be used until it is fixed
• P2 (Medium): During the normal course of the development activities defect
should be resolved. It can wait until a new version is created
• P3 (Low): The defect is an irritant but repair can be done once the more serious
defect have been fixed

Tips for determining Severity of a Defect

• A very low severity with a high priority:
• A logo error for any shipment website, can be of low severity as it not
going to affect the functionality of the website but can be of high
priority as you don't want any further shipment to proceed with wrong
logo.
• A very high severity with a low priority:
• For flight operating website, defect in reservation functionality may be
of high severity but can be a low priority as it can be scheduled to
release in a next cycle.

Some more examples…
• Example for High Priority & High Severity defect:
• If 'Login' is required for an Application and the users are unable to login to the
application with valid user credentials. Such defects need to be fixed with high
importance. Since it is stopping the customer to progress further.
• Example for Low Priority and High Severity defect:
• If an application crashes after multiple use of any functionality i.e. if ‘Save’ Button
(functionality) is used for 200 times and then the application crashes, such defects have
High Severity because application gets crashed, but Low Priority because no need to
debug right now you can debug it after some days.
• Example for High Priority & Low Severity defect:
• If in a web application, company name is miss spelled or Text “User Nam:” is displayed
instead of “User Name:” on the application login page. In this case, Defect Severity is
low as it is a spell mistake but Priority is high because of its high visibility.

• Low priority-Low severity - A spelling mistake in a page not
frequently navigated by users.
• Low priority-High severity - Application crashing in some very corner
case.
• High priority-Low severity - Slight change in logo color or spelling
mistake in company name.
• High priority-High severity - Issue with login functionality.

Defect Resolution
• After receiving the defect report from the testing team, development team conduct a
review meeting to fix defects. Then they send a Resolution Type to the testing team
for further communication.
• Resolution Types:-
• Accept
• Reject
• Duplicate
• Enhancement
• Need more information
• Not Reproducible
• Fixed
• As Designed

Defect Triage
• Defect triage is a process that tries to do the re-balancing of the process where test
team faces the problem of limited availability of resources.
• When there are large number of the defects and limited testers to verify them, defect
triage helps trying to get as many defects resolved based on defect parameters like
severity and priority.
• Defect Triage Process:

The triage process includes following steps
• Reviewing all the defects including rejected defects by the team
• Initial assessment of the defects is based on its content and respective
priority and severity settings
• Prioritizing the defect based on the inputs
• Assign the defect to correct release by product manager
• Re-directs the defect to the correct owner/team for further action

Guidelines that every tester should consider
before selecting severity
• Understand the concept of priority and severity well
• Always assign the severity level based on the issue type as this will affect its
priority
• Understand how a particular scenario or test case would affect the end-
user
• Need to consider how much time it would take to fix the defect based on
its complexity and time to verify defect

Exercise
• Assign the Severity for the following issues.
1 The website performance is too slow
2 The login function of the website does not
work properly
3 The GUI of the website does not display
correctly on mobile devices
4 The website could not remember the user login
session
5 Some links doesn’t work

Here are the recommended answers
No. Description Severity Explanation
1 The website performance
is too slow
High The performance bug can cause huge inconvenience to
user.
2 The login function of the
website does not work
properly
Critical Login is one of the main function of the banking website if
this feature does not work, it is serious bugs
3 The GUI of the website
does not display correctly
on mobile devices
Medium The defect affects the user who use Smartphone to view
the website.
4 The website could not
remember the user login
session
High This is a serious issue since the user will be able to login but
not be able to perform any further transactions
5 Some links doesn’t work Low This is an easy fix for development guys and the user can
still access the site without these links

Tips for good Bug report
• Structure: test carefully (Use deliberate, careful approach to testing)
• Reproduce: test it again (rule of thumb 3 times)
• Isolate: test it differently (Change variables that may alter symptom)
• Generalize: test it elsewhere Does the same failure occur in other modules or locations?
• Compare: review results of similar tests (Same test run against earlier versions)
• Summarize: relate test to customers (Put a short “tag line” on each report)
• Condense: trim unnecessary information (Eliminate extraneous words or steps)
• Disambiguate: use clear words (Goal: Clear, indisputable statements of fact)
• Neutralize: express problem impartially (Deliver bad news gently)
• Review: be sure (Peer review)

Sates of Defects
• New: A bug is reported and is yet to be assigned to developer
• Open: The test lead approves the bug
• Assigned: Assigned to a developer and a fix is in progress
• Need more info: When the developer needs information to reproduce the bug or to fix the bug
• Fixed: Bug is fixed and waiting for validation
• Closed: The bug is fixed, validated and closed
• Rejected: Bug is not genuine
• Deferred: Fix will be placed in future builds
• Duplicate: Two bugs mention the same concept
• Invalid: Not a valid bug
• Reopened: Bug still exists even after the bug is fixed by the developer

Test Cycle Closure
• Activities
• Evaluate cycle completion criteria based on Time, Test coverage, Cost, Software, Critical Business
Objectives , Quality
• Prepare test metrics based on the above parameters.
• Document the learning out of the project
• Prepare Test closure report
• Qualitative and quantitative reporting of quality of the work product to the customer.
• Test result analysis to find out the defect distribution by type and severity.
• Deliverables

What is Agile?
• AGILE is a methodology that promotes continuous iteration of
development and testing throughout the software development life cycle
of the project.
• Both development and testing activities are concurrent unlike the Waterfall
model.
• The agile software development emphasizes on four core values.
• Individual and team interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan
