Testing Strategies

• Stub testing
• White-box
• Black-box

Stub test

• Create the methods/functions declaration, without implementing them
• One scenario is use in developing user interface, those "backend" functions are declared as stub while the user interface can be program/test independently 

White-box testing

• Testing every path through the program code
• i.e. the test based on having access to the source code, knowing "HOW" it works

Black-box testing

• Compare expected results with actual results when a program is run
• In contrast to white box, no knowledge about HOW the code works
• Can perform by testers who is not the one to create the program

Testing methods

• Module test / unit test - testing on individual components, usually whitebox test
• Integration test / (sub) system test - Combining multiple modules to test
• Alpha testing - In house test before release to customer
• Acceptance test - Customer checks the program meets their requirements and work as expected, usually part of the hand-over process
• Beta testing - Early release to chosen user group, beta testers will perform the test in their own environment and report issues to the developers. 

Test plan

• Should include the followings:
  • Test case number (serial number)
  • Description
  • Test data
  • Type of test data
  • Expected result
  • Actual outcome
  • Remedial plan

Types of test data

• Normal (valid)
• Abnormal (invalid)
• Extreme / Boundary (can be valid or invalid) 

Project management

• Manages project resources
• which includes time, human, equipment etc.

PERT chart

• Program Evaluation Review Technique (PERT)
• A method to help planning and scheduling of a large and complex project
• Activity - The work need to be done
• Milestone- Scheduled event after certain activity is done

Critical Path

• Longest possible continuous pathway from start to finish
  • Adding all serial activities
  • Adding longest path in parallel activities
• Any delay in the critical path results the project delayed

Gantt Chart

• Graphical representation of a project schedule
• Helps to plan activities in a project
