basics of automation & manual software testing
DESCRIPTION
Software testing is the process of evaluation of a software item to detect differences between given input and expected output. Software Testing is the process of assuring that product which is manufactured by developer is meeting the user requirement. The motive to perform testing is to find the bugs and make sure that they get fixed. The purposes of testing are: Quality assurance, Verification and Validation, To find the bugs before the product is released to customer. To improve the quality of the product To evaluate that the product is according to requirements By, Mr. Surendra Rawat, QA Tester at www.gusani.comTRANSCRIPT

INTRODUCTION OF TESTING What is Testing: Software testing is the process of evaluation of a software item to detect
differences between given input and expected output. Software Testing is the process of assuring that product which is manufactured by developer
is meeting the user requirement. The motive to perform testing is to find the bugs and make sure that they get fixed.
The purposes of testing are: Quality assurance, Verification and Validation, To find the bugs before the product is released to customer. To improve the quality of the product To evaluate that the product is according to requirements

WHO AND WHEN TO START TESTING Who does testing: Following professionals are involved in testing of a system
within their respective capacities: Software Tester Software Developer Project Lead/Manager End User
When to Start Testing? Testing is done in different forms at every phase of SDLC like during Requirement
gathering phase, the analysis and verifications of requirements are also considered testing.

TYPE OF TESTING Manual testing: This type includes the testing of the Software manually i.e.
without using any automated tool or any script. A manual tester would typically perform the following steps for manual
testing: Understand the functionality of program Prepare a test environment. Execute test case(s) manually Verify the actual result Record the result as Pass or Fail Make a report of the Pass and Fail test cases Publish the report

Pros - Cons Advantage:-
Manual testing can be use in both small and big project. We can easily reduce and add our test case according to project movement. Easy to learn for new people who enters in manual testing. Manual testing is more reliable then automated (in many cases automated not cover all cases) .
Disadvantage:- GUI object size difference and color combination etc is not easy to find out in manual testing. Actual load and performance is not possible to cover in manual testing for large number of users.

Automation testing Automation testing: Automation testing which is also known as Test Automation.
In this testing, the tester writes scripts and uses another software to test the software. There are many Tools are use in automation Testing.
Software testing tools: HP Quick Test Professional Selenium Testing Anywhere WinRunner LaodRunner

Pros - Cons Advantage
Easy to cover up all cases in a limited time period. You can perform different types of testing’s like load testing, performance testing using
tool. Automated testing can be performed on different operating systems.
Disadvantage Purchase a tools and Maintenance. Automation testing is more expensive work as comparing with manual testing. Language wise there are many tools to test various type of software, means all tools will
not support to all software which are developed in different languages.

SDLC AND STLC Software Development Life Cycle:
There are six type of SDLC. Requirement phase Design phase Coding (programming) Testing Release (Production) Maintenance (Support)
Software Testing Life Cycle: There are seven type of STLC. Requirement Study Test Planning Writing Test Cases Review the Test Cases Executing the Test Cases Bug logging Close or Reopen bugs

BASIC TYPE OF TESTING Black Box Testing: The technique of testing without having any knowledge of the interior
workings of the application is Black Box testing. The tester is oblivious to the system architecture and does not have access to the source code. It is also called behavioral, functional and close box testing.
White Box Testing: White box testing is require understanding of internal logic and structure of the code. White box testing is also called glassbox testing or open box, structural,clearbox testing.
Different types of software testing: Unit testing Shakeout testing Smoke testing(Ad-hoc testing)

SAMPLE OF BUG CASESample of Bug Case:
Bug Name: Application crash on clicking the SAVE button.
Bug ID: (It will be automatically created by the BUG Tracking tool once you save this bug)
Area Path: USERS menu > New Users
Severity: High (High/medium/Low)
Priority: High (High/medium/Low)
Assigned to: Developer-X
Reported By: Your Name
Reported On: Date

…continue Severity: Describes the bug in terms of functionality. Priority: Describes the bug in terms of customer. Ex.
High Priority and Low Severity: Company logo is not properly displayed on their website. High Priority and High Severity: Suppose you are doing online shopping and filled payment
information, but After submitting the form, you get a message like "Order has been cancelled." Low Priority and High Severity: If we have a typical scenario in which the application get crashed, but
that scenario exists rarely. Low Priority and Low Severity: There is a mistake like "You have registered success" instead of
successfully, success is written.

WATER FALL MODEL Water Fall Model: History: The first formal description of the waterfall model is often cited as a 1970
article by Winston W. Royce Features:
A Water Fall Model is easy to flow. It can be implemented for any size of project. Every stage has to be done separately at the right time so you cannot jump stages. Testing is done at every stage.
