Unit Testing

Testing small units of code (like functions) individually to make sure they work correctly.

Black Box Testing

Testing a unit of code without knowing its internal workings; focuses on input and expected output only.

White Box Testing

Testing a unit of code using its internal structure to ensure every path is tested.

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
