Pre-Conditions are specific conditions that must be met before an action can occur in a system or software. They define the expected state required for successful execution of a function or test case.
Key Aspects:
- Define Necessary Requirements: Establish what must be true before an operation starts.
- Ensure System Readiness: Confirm that the system is in the correct state for execution.
- Prevent Errors: Help avoid issues by ensuring all prerequisites are fulfilled.
Examples:
- The user must be logged in.
- Required data must be available.
- The application must be installed correctly.
Pre-conditions are essential for maintaining logical consistency in software operations, ensuring that functions execute as intended without unexpected behaviour.
