This document provides an overview of software quality assurance and testing. It defines quality as meeting specifications and customer expectations. Software testing investigates quality by providing stakeholders information. Testing is important to prevent defects, as shown by examples of bugs that caused spacecraft and airplane failures costing lives and money. Quality assurance focuses on preventing defects through planning and verification, while quality control identifies defects through action and validation. Defects can be costly so issue tracking systems are used to manage bug lifecycles. Manual testing is time-consuming and relies on human resources while automation testing is faster, more reliable and programmable.

3. What does ‘Quality’ mean?
Quality:
- Conformance to specifications
- Product or Service meets the needs of the customer
- Exceeding customer expectations

4. Software Testing
Software Testing - an investigation conducted to provide
stakeholders with information about the quality of the
product or service

9. Defect in software
Defect(Bug) is an error in a computer or
system that causes it to produce an
incorrect or unexpected result.

16. Manual Testing vs Automation Testing
1. Time consuming and tedious: Since test cases are executed by
human resources so it is very slow and tedious.
1. Fast Automation runs test cases significantly faster than human
resources.
2. Huge investment in human resources: As test cases need to
be executed manually so more testers are required in manual testing.
2. Less investment in human resources:Test cases are executed by
using automation tool so less tester are required in automation testing.
3. Less reliable: Manual testing is less reliable as tests may not be
performed with precision each time because of human errors.
3. More reliable: Automation tests perform precisely same operation
each time they are run.
4. Non-programmable: No programming can be done to write
sophisticated tests which fetch hidden information.
4. Programmable: Testers can program sophisticated tests to bring out
hidden information.
