Use SOLID Principles To Become Better Automation Tester by Gustavo Daniel Moreira
SOLID principles are the first five object-oriented design principles by Robert C. Martin, popularly known as Uncle Bob.
This article explores each individual principle and how these SOLID principles can make us better at developing automation tests.
- Single Responsibility Principle (SRP): A class should have one, and only one, reason to change
- Open Closed Principle (OCP): Software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification
- Liskov Substitution Principle (LSP): Subtypes must be substitutable for their base types
- Interface Segregation Principle (ISP): Make fine grained interfaces that are client specific
- Dependency Inversion Principle (DIP): Depend on abstractions, not on concretions
