What are the criticisms of the Singleton pattern in software design?
The Singleton pattern is often criticized for promoting global state, which can lead to issues in testing and maintenance.
Can you explain how it affects unit testing?
Sure! Singletons can make unit tests difficult because they introduce hidden dependencies, making it hard to isolate tests.
Are there any alternatives to the Singleton pattern?
Yes, alternatives include dependency injection and using static classes or modules, which can provide similar functionality without the downsides.
What are some real-world examples where the Singleton pattern caused problems?
One example is in large applications where multiple components rely on a Singleton, leading to tight coupling and making changes risky.
