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.
