Questions and Answers

What is the purpose of the implementation phase in software development?

  • To create test cases
  • To document the system architecture
  • To translate software design into source code (correct)
  • To conduct system testing

What is the main goal of unit testing during the implementation phase?

  • To develop the system architecture
  • To test individual modules for correct functionality (correct)
  • To integrate modules into a complete system
  • To document each module

Why are different modules integrated in a planned manner, instead of all at once?

  • To delay the system testing phase
  • To ensure proper functionality and detect errors effectively (correct)
  • To simplify the documentation process
  • To save time during the implementation phase
