provider_test.go - Overview​

  1. Overview

This file contains unit tests for the memory cache provider implementation. It tests the functionalities like creating a new cache, storing, retrieving, setting TTL, removing single and multiple keys, and the overall caching mechanism.

  1. Detailed Documentation

TestNew​

  • Purpose: Tests the New function to ensure it creates a new memory cache provider instance without errors, the cache client is not nil, and it connects successfully.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

CacheableEntity​

  • Purpose: Defines a struct that implements the BinaryMarshaler and BinaryUnmarshaler interfaces for testing the cache.
  • Fields:
    • Key (string): A string key.
    • Value (int): An integer value.
    • Expiry (time.Duration): Duration for expiry.

CacheableEntity.MarshalBinary​

  • Purpose: Marshals the CacheableEntity struct into a binary representation using JSON.
  • Parameters: None
  • Returns:
    • []byte: The binary representation of the struct.
    • error: An error, if any.

CacheableEntity.UnmarshalBinary​

  • Purpose: Unmarshals binary data into the CacheableEntity struct. Currently, it's a no-op.
  • Parameters:
    • data ([]byte): The binary data to unmarshal.
  • Returns:
    • error: An error, if any. Currently always nil.

DCacheableEntity​

  • Purpose: Defines another struct similar to CacheableEntity for testing different types during retrieval.
  • Fields:
    • Key (string): A string key.
    • Value (int): An integer value.
    • Expiry (time.Duration): Duration for expiry.

DCacheableEntity.MarshalBinary​

  • Purpose: Marshals the DCacheableEntity struct into a binary representation using JSON.
  • Parameters: None
  • Returns:
    • []byte: The binary representation of the struct.
    • error: An error, if any.

DCacheableEntity.UnmarshalBinary​

  • Purpose: Unmarshals binary data into the DCacheableEntity struct. Currently a no-op.
  • Parameters:
    • data ([]byte): The binary data to unmarshal.
  • Returns:
    • error: An error, if any. Currently always nil.

TestStoreWithNilPointer​

  • Purpose: Tests the Store function with a nil pointer to ensure it returns an error.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestStoreWithStruct​

  • Purpose: Tests the Store function with a non-pointer value to ensure it returns an error.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestStoreWithNonNilPointer​

  • Purpose: Tests the Store function with a non-nil pointer to ensure it stores the value without errors.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestRetrieveWithNilPointer​

  • Purpose: Tests the Retrieve function when attempting to retrieve data into a nil pointer. It asserts that an error is returned and the retrieve status is cache.RetrieveStatusError.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestRetrieveWitNonPointer​

  • Purpose: Tests the Retrieve function when attempting to retrieve data into a non-pointer variable. It asserts that an error is returned and the retrieve status is cache.RetrieveStatusError.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestRetrieveWithDifferentTypes​

  • Purpose: Tests the Retrieve function when the type of the stored data and the retrieval target are different. It asserts that an error is returned and the retrieve status is cache.RetrieveStatusError.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestRetrieveWithSameTypes​

  • Purpose: Tests the Retrieve function with the same types for stored and retrieved data. It asserts that no error occurs, the retrieve status is cache.RetrieveStatusHit, and the retrieved value matches the stored value.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestSetTTL​

  • Purpose: Tests the SetTTL function to ensure it updates the TTL of a cached item correctly. It verifies that the item expires after the initial TTL, then resets the TTL and verifies that the item is accessible after the initial TTL but before the new TTL expires.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestRemove​

  • Purpose: Tests the Remove function to ensure it removes a key from the cache.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestBulkRemove​

  • Purpose: Tests the BulkRemove function to ensure it removes multiple keys from the cache.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None

TestCache​

  • Purpose: Tests the basic caching functionality, including storing, retrieving, and removing an item.
  • Parameters:
    • t (*testing.T): Testing context.
  • Returns: None
