Study Notes

UML Class Diagrams

  • Main purpose is to visualize the structure of a system, showing classes, attributes, methods, and relationships among objects.
  • Components typically include classes, associations, and multiplicity; elements like comments or notes are often included.
  • Elements NOT part of a UML Class diagram include specific implementation details or coding constructs.

Software Testing

  • Primary purpose is to identify defects in a software product, ensuring it meets requirements and functions as intended.
  • Crucial areas for coding include validation, error-handling, and system security, emphasizing the need for robustness and reliability.

Software Deployment Process

  • Testing occurs in the deployment stage, where software is evaluated before delivery to ensure quality and performance.
  • Module level testing focuses on validating the functionality of individual modules within the system.

Collaboration and Version Control

  • A common cloud-based collaboration tool known for hosting code repositories is GitHub.
  • Version control tools like Git help track changes in code and manage collaborative development efforts.

Module Testing Methods

  • Incremental module testing involves testing modules one at a time as they are developed, while non-incremental testing assesses all modules at once after completion.

Software Maintenance

  • Maintenance type focused on modifying software to keep it up-to-date includes corrective, adaptive, and perfective maintenance.
  • Common reasons for software maintenance consist of fixing bugs, improving performance, or adapting to new hardware/software environments.

Integration Testing

  • Activity involving testing newly created modules together in the system is known as integration testing, assessing overall functionality and interaction among components.
