Overview

A concise summary of the basic types of test cases and how to identify them.

Purpose of Testing

Discover bugs
Quality assurance
Quality improvement (refactoring)

Types of Tests

Unit Test
- Tests to verify the specifications of methods
- Targets public methods in the domain layer
Integration Test
- Tests based on use cases (a series of processes)
- Prioritizes business-critical cases

Identifying Test Cases

Normal Cases
- Check if the expected output is produced for the expected input
Abnormal Cases
- Check if the system can handle unexpected inputs
Equivalence Partitioning
- Divide into equivalence classes... Group test results (divide by criteria, e.g., language, presence of symbols, domain of address, etc.)
- Select representative values from each equivalence class
Boundary Value Analysis
- Use values that are boundaries between equivalence classes as input

Identifying test cases for unit tests and integration tests should consider the above perspectives, along with business factors such as quality and effort.
