Different design patterns in software engineering

• Creational patterns (e.g. Singleton, Factory)

• Structural patterns (e.g. Adapter, Decorator)

• Behavioral patterns (e.g. Observer, Strategy)

Different types of string test types include equality, containment, length, case sensitivity, and pattern matching.

• Equality test: comparing two strings to see if they are exactly the same

• Containment test: checking if a string contains a specific substring

• Length test: determining the length of a string

• Case sensitivity test: checking if two strings are equal while considering case

• Pattern matching test: using regular expr...read more
