How can I test an LRU cache implementation?

How can I test an LRU cache implementation?

You can test an LRU cache by checking its behavior with various operations like put, get, and eviction.

What specific test cases should I consider?

Consider cases like adding items until capacity is reached, accessing items to check if they are cached, and ensuring eviction works.

How do I measure the performance of the cache?

You can measure performance by tracking hit/miss ratios and the time taken for operations under different loads.

Are there any libraries that can help with testing?

Yes, libraries like JUnit for Java or pytest for Python can help you write and run your test cases effectively.
