Study Notes

Testing and Software Development

When to stop testing: when all reported problems have been repaired.
Unnecessary testing: testing with invalid or unexpected data, testing with negative numbers.

SDLC (Software Development Life Cycle)

SDLC is a process of planning, creating, testing, and deploying an information system.

Test Data

Valid test data: values between 10,000 and 99,999 inclusive.

Performance and Security Testing

Performance testing: verifying the application's performance under maximum load.
Security testing: testing the application's security and vulnerabilities.

Jira and Project Management

Jira: a system for managing work in a project team.
Not a social networking application.

Testing Principles

Testing can show the presence of defects but cannot prove their absence.
Testing can prove the absence of defects but not their presence.

Types of Testing

Testing: verifying software regardless of the type of testing applied.
Boundary Value Analysis: a black box testing technique.
Sanity testing: verifying that the application's main components function correctly.
Regression testing: verifying that recent changes have not negatively affected existing functionalities.
Smoke testing: verifying that the application's critical functionalities work.
