Introduction to Software Testing
When to consider that a software has bugs?
do the product specification doesn't mention
doesn't do the product specification doesn't mention but should
difficult to understand, hard to use, or anything that a tester view as not right to end user
do a thing that the product specification says shouldn't
does not meet product specification says
Reasons bugs occur in Software Development
volatile requirements(requirement always change)
missing requirements / requirements are not well documented
lack of communication
Definition of Software Testing
a process by which people, methods, measurements, tools and equipment are integrated to test a software product
Process : a quality process and planning determines the success of the test effort
People : need trained and skilled people with the right and positive attitudes(professional discipline)
Methods : different methods and techniques to be applied
Measurements : calculate the quality of software product
Tools and Equipments : variety tools to make testing more efficient and faster
Basic Forms of Testing
Validation : requirements for a specific intended use have been fulfilled
Verification : specified requirements have been fulfilled
Objectives of Software Testing
To produce a quality software product, which the software can be used and used successfully
To bring the tested software, after correction of identified errors and retesting(implementation), to an acceptable level of quality
To identify & reveal as many errors as possible in the tested software
To compile a record of software errors for use in error preventation
To perform the required tests efficiently and effectively, within budgetary and scheduling limitations
General Failure Terminology(include relationship)
Fault : incorrect behavior of program in response to real-world resulting from errors
Failure : system does not perform required function within specified limits
Error : human action produce incorrect result
Relationship : A person makes an error -> leading to a fault in the program -> causing a failure in operation
Critical Choices
When to test? : test early
How to test? : test effectively and cost-effectively
What to test? : Test right things
Fundamental of Test Process
Test implementation and test execution
Test evaluation of the test exit criteria
Test analysis and test design
Post testing activities : Review
Test Planning and Control
Types of Software Testing
System Testing
Performance Testing
regression Testing
Integration Testing :
User Acceptance Testing
Unit Testing :
Usability Testing
Good Tester
relentless
creative
troubleshooters
good judgement
tactful and diplomatic
explorers
