Current behavior

I didn't find any documentation how to write tests for CacheModule or change store option

Expected behavior

For example, we are using CacheModule with Redis in production.
In the test app, we want to use CacheModule with memory.

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

Environment

For Tooling issues:
- Node version: any  
- Platform: any 
- NestJS: 6.7.1

  .overrideProvider(CACHE_MODULE_OPTIONS) // exported from @nestjs/common
  .useValue(newCacheModuleOptions)

might help you.
