Chapter 5.5, Problem 25STE
Program Plan Intro

Testing:

  • It denotes an activity to check whether actual results match expected results.
  • It guarantees that software system is defect free.
  • It involves execution of a software component for evaluating one or more interest properties.
  • It identifies errors, gaps or requirements that are omitted related to actual requirements.
  • It could be performed manually or using automated tools.
  • It can be classified as white or black box testing.
  • The manual testing would include testing of software short of any tool.
    • The tester behaves as an end-user.
    • It tests software for identifying any behavior that is unexpected.
    • The different stages include unit, integration, system as well as user acceptance testing.
  • The automation testing uses software to test product.
    • It includes automation for a manual process.
    • The test scenarios are been re-run that are been performed manually.
    • It is used for testing application from performance, load in addition to stress view point.

Debugger:

  • A debugger denotes a tool that allows programmer to set break points.
  • It steps through the code line by line.
  • It inspects or modifies the value of variables.
  • It denotes usage of instruction set simulators rather than running directly on processor.
  • It helps to achieve a higher control level over its execution.
  • It allows debuggers to stop or halt program based on specific conditions.
  • The execution speed decreases due to use of simulators.
