> Software Testing can be done in two ways one is Manual Testing another is Test Automation or Automated Testing.
> Testing computer software manually in order to find defects without using tools or automation scripts.
> Testing Computer Software by using Automation tool or Automation script.
--------------------------------------------------------

We have so many SDLC models available in the IT industry, we can segregate them in to two categories.

i) Sequential Models (Waterfall, V Model etc...)
ii) Incremental / Iterative models (Spiral model, Agile models etc...) 
--------------------------------------------------------

We have Four levels of Testing for General or independent Software applications 

i) Unit Testing Testing of individual software components.
Testers: Developers

ii) Integration Testing 
Testing integration or interfaces between components, interactions to different parts of the system such as an operating system, file system and hardware.
Testers: Developers or Independent Testers

iii) System Testing 
Testing an integrated System to verify that it meets specified requirements.
Testers: Independent Testers

iv) Acceptance Testing
User Acceptance Testing 
Testers: Customers /End users

Operational Acceptance Testing
System Administration staff.

Certification Testing
Testers: Certified Testers

For distributed Software applications 5 levels of Testing
i) Unit Testing
ii) Component Integration Testing
iii) System Testing
iv) System Integration Testing
v) Acceptance Testing
--------------------------------------------------------

i) Functional Testing
    Functionality Testing
     Security Testing

ii) Non Functional Testing
     Performance Testing
     Usability Testing
     Configuration Testing
     Reliability Testing
     Recovery Testing
     Localization Testing etc...
--------------------------------------------------------

i) Static Techniques
Static testing is the testing of the software work products manually, or with a set of tools, but they are not executed.

Example: Reviews, Walk trough, Inspection etc...

ii) Dynamic Techniques
> Testing that involves the execution of the software of a component or system.

a) White box Test design techniques    
    Statement testing
    Condition testing
    Decision testing etc...

b) Black box Test design techniques    
    Equivalence partitioning / Equivalent Classes
    Boundary Value Analysis
    Decision tables
    State transition Testing
    Use case Testing etc...

c) Experience based Techniques    
    Error Guessing
    Exploratory Testing etc...
--------------------------------------------------------
6) Software Test Process / Software Testing Life Cycle
Phases of Software Test Process
i) Test Planning
Input or References
Requirements
Project plan
Test Strategy
-----------
Design Documents
Corporate standards documents
Process guideline docs
etc...
----------------
Tasks
    Understanding and Analyzing the Requirements
    Risk Analysis
    Test Strategy implementations
    Test Estimations(Scope, Time, Available resources, Budget etc...)
    Team formation
    Test plan documentation
    Configuration management planning
    Creating RTM document
    Define Test Environment Setup

Output
Test Plan document
----------------------------------------
ii) Test Design
Input or References 
Requirements

        Select Test cases for Regression Testing
        Sanity Testing
        Regression testing cycle 1
        Defect Reporting
        Defect Tracking
        Select Test cases for Regression Testing
        Sanity Testing
        Regression testing cycle 2
        .
        .
        .
        Final Regression 

Output 
Opened and Closed Defect Reports
Tested Software
------------------------------------
iv) Test Closure             
Input or References 
Requirements
Test plan
Opened and Closed Defect Reports
etc...
-----------------
Test Summary Report template
----------
Tasks    
    Collect all Artifacts
    Evaluate the Exit Criteria
    Test Summary Report
    Sending Test deliverables to customer
    Improvement suggestions for future projects.
--------------------------------------------------------
    
i) ISO (Terminology, Process Guidelines etc...)
ii) IEEE (Terminology, Test Documentation Standards etc...)
iii) CMM/CMMI (Process)
--------------------------------------------------------

i) Test Policy
A high level (company level) document describes principles, approach and major objectives of the organization regarding Testing.

ii) Test Strategy
A high level document of the Test Levels to be performed and the Testing within those levels for an Organization.

iii) Test Plan
A document describing the scope, approach, resources, and schedule of intended activities.

iv) Test Scenario
An item or event of a component or system that could be verified by one or more Test cases.

v) Test Case
A set of input values, execution preconditions, expected result and execution post conditions developed for a particular objective or Test condition.

vi) Test Data
Data that exits before a test is executed and that effects or is effected by the component or System under test.

vii) Defect Report
A document reporting of ant flaw in a component or System that can cause the component or system to fail to perform its required function.

viii) Test Summary Report
A document summarizing testing activities and Result. It also contains evaluation of the corresponding test items against exit criteria.

i) BFSI (Banking, Financial Services and Insurance)
ii) ERP (Enterprise Resource Planning)
iii) Telecom
iv) Healthcare
v) Ecommerce
vi) Retail Market

Others (System Software, Games, Documentation software etc...)
