Study Notes

Software Testing Types

Different types of software testing exist, each targeting a specific aspect of the application
This list is not exhaustive, but covers major testing types

Unit Testing

Most basic testing type
Tests individual units of code (functions)
Ensures each unit produces correct results on its own
Easier to find bugs in smaller units
Builds on established, bug-free code
Tests are usually automated
Checks functions by supplying known input and verifying the expected output

Black Box Testing

Treats functional units like 'black boxes'
No knowledge of internal code structure
Tests based solely on input/output relationships
Commonly the first approach in testing design

White Box Testing

Opposite of black box testing
Uses knowledge of internal code structure to design tests
Tests every possible path through the code
Ensures coverage of all code sections
Increased certainty of correct functionality

Integration Testing

Tests combination of units, not individual functions
Validates how units interact together
Assesses if combined units work correctly
Can use unit testing frameworks or other methods

Functional Testing

Focuses on business requirements
Verifies correct output without inspecting internal system state
Checks if expected functionality aligns with business needs
Unlike integration tests, it doesn't need to check exact steps/implementation

End-to-End Testing

Simulates user interactions
Ensures all tasks users perform function correctly
Often difficult to automate and maintain due to changing user flows

Load Testing

Checks software behavior under high load conditions
Examines if the software handles expected number of concurrent users
May combine with stress testing to determine breaking point

Security Testing

Assesses adherence to security requirements
Verifies the application's security measures
Involves attempting to exploit vulnerabilities to determine security weaknesses

Acceptance Testing

Verifies application meets all business needs
Runs tests simulating end-user scenarios
Signals successful completion of the customer's requirements

Regression Testing

Reruns existing tests after code changes
Ensures that new or changed code doesn't break old functionality
Critical for ensuring maintainable, stable code bases
