Introduction

• Test cases are a series of tests that each have a
  specific objective and will be conducted by the
  testers
• Should be created at the beginning of the system
  development life cycle
• Continuously updated as development evolves

3
Developing a Test Case

• Need to know the
• Purpose of the test
• Attributes being tested
• Event that will cause the attribute to change
• Expected result
• Actual result
• Pass or fail

4
Unit Testing

• Black-Box
• - Focus on if the class meets
  the requirements
• Used for normal testing
• White-Box
• - Reviewing code for errors that may not be
  found from Black-Box testing
• Used for when the complexity is high

5
Integration Testing

• User Interface
• -Test every control on the UI (such as menus and
  keyboard shortcuts)
• Used for normal integration testing
• Use-Case
• -Go through every use case
• Used with interface testing since it does not
  test all of the interfaces

6
Integration Testing continued

• Interaction
• -Testing each class on its own until all tests
  are successful, then test all classes together
• Used for data processing
• System Interface
• -Testing communication and data transfers
  between systems
• Used when the system exchanges data with another
  system

7
System Testing

• Requirement
• -Ensures that the integration testing didnt
  introduce new errors.
• -Checks for improper actions (ex. Entering blank
  records)
• Used for normal testing
• Usability
• -System ease of use
• Used for when the user interface is important

8
System Testing continued

• Security
• -Testing the system infrastructure for security
  holes and risks, as well as disaster recovery
• Used when security is important
• Performance
• -Testing system and database load (large volume
  of users and data)
• Used for when system speed is important

9
Acceptance Testing

• Alpha
• -Internal testing of previous tasks to ensure
  they accept the system
• Used for normal acceptance testing
• Beta
• -Users monitor system for errors or improvements
  by entering real data
• Used for normal acceptance testing
