• Use Case Testing
• What is the Use Case?
• A use case is an approach for system analysis
  that identifies, clarifies, and organises needs.
  Use cases are a collection of conceivable
  sequences of interaction between the system and
  the user in a specific environment to achieve a
  specific goal.
• It is a document of action performed by the user
  and how the system behaved on it.

• Elements of Use Cases
• A use case has three major elements i.e Actor,
  Action, System
• Actor - Is a user that interacts with the
  system, and performs some functions to achieve a
  goal.
• Action - Is a system response, behavior, and
  final outcome that completes the process.
• System - The process and steps taken to reach
  the end goal, including the necessary functional
  requirement and their anticipated behavior.

• Types of Use Case -
• 1). Basic Use Case - In this method the positive
  aspect of the application, and the positive
  scenarios are tested with valid data.
• 2). Alternate Use Cases - In this case the
  alternate method is used to test the error
  handling of the system with alternate values.
• 3). Boundary Use Case - This is the method of
  testing the use case at maximum and minimum input
  values.
• 4). Negative Use Case - In this case, negative
  inputs are used to test the use case to detect
  and prevent errors.
• 5). Integration Use Case - In this method of
  testing, the use case is being tested to process
  data within the system.
• 6). Performance Use Case - In this case the
  objective of testing is to test the scalability,
  reliability, and response time of use cases.
