Explain what is meant by caching test data in the cache to speed up test execution.

Caching test data is a practice where data needed for tests is loaded once and stored for quick access (for example, in memory or local storage). This allows reusing this data across multiple test runs without repeatedly accessing slow sources (databases, external services).

Advantages:

• Faster test execution by reducing data preparation time.
• Reduced load on external systems.

Example: if you have a set of users for testing, you can load them once into cache and use them in different tests instead of creating or loading them anew before each test.
