Resolves #543

What is the feature

This feature adds integration tests for Redis to ensure that our application interacts correctly with a real Redis instance. It involves implementing tests in the existing CrispyWaffle.IntegrationTests project, configuring Redis instances for local development using Docker Compose, and setting up Redis for continuous integration builds in AppVeyor.

Why we need the feature

Integration tests are essential to validate that our application correctly communicates with external services like Redis. By testing against a real Redis instance, we can catch issues related to configuration, network communication, and data serialization that unit tests may not cover. This enhances the reliability and robustness of our application and prevents bugs from reaching production.

How to implement and why

The implementation will proceed in the following steps:

1. Implement Redis Integration Tests in CrispyWaffle.IntegrationTests:

   • Create Test Class RedisCacheRepositoryTests:

     • In the existing CrispyWaffle.IntegrationTests project, under the directory Cache/Redis, create a new test class named RedisCacheRepositoryTests.
     • Reason: Organizing tests in this manner maintains a clean project structure and makes the tests easily discoverable.

   • Write Integration Tests:

     • Implement tests that cover various Redis operations such as setting, getting, and deleting cache entries.
     • Include edge cases and error handling scenarios.
     • Reason: Comprehensive tests ensure that all aspects of Redis interactions are validated.

2. Configure Redis Instance for Local Development:

   • Utilize Existing docker-compose.yml:

     • Since the docker-compose.yml file already includes a Redis service, ensure that developers are aware and use it for running Redis locally.
     • Reason: Using Docker Compose allows for easy setup and teardown of Redis instances, providing a consistent environment for all developers.

   • Documentation:

     • Update the project documentation to guide developers on how to start the Redis service using Docker Compose.
     • Reason: Clear instructions help new and existing team members set up their development environment efficiently.

3. Update appveyor.yml for Continuous Integration:

   • Configure Redis on AppVeyor:

     • Modify the appveyor.yml file to include steps that install and start Redis on the CI build machine.
     • Use the provided PowerShell script to download, install, and start Redis 5.0.14.
     • Reason: Ensuring that Redis is running during CI builds allows integration tests to execute in the build pipeline, catching issues early.

   • Verify Redis Availability:

     • Add a build step to verify that the Redis server is running before tests are executed.
     • Reason: This ensures that integration tests will not fail due to Redis not being available on the CI server.

4. Maintain Configuration Files:

   • Ensure docker-compose.yml and appveyor.yml are Up-to-date:
     • Review the existing configuration files to confirm they are correctly set up for Redis.
     • Make any necessary adjustments to port mappings or service configurations.
     • Reason: Accurate configuration files are crucial for the smooth operation of development and CI environments.

5. Test Across Environments:

   • Local and CI Testing:
     • Run the integration tests locally and in the CI environment to verify that Redis is correctly configured and that the tests pass.
     • Reason: Validating in both environments ensures consistency and reliability.

6. Documentation and Maintenance:

   • Update README and Documentation:

     • Provide guidelines on running integration tests and managing the Redis instance.
     • Reason: Helps maintain the project and assists future developers in understanding the setup.

   • Add Comments to Configuration Scripts:

     • Comment the steps in appveyor.yml for clarity.
     • Reason: Improves maintainability of the CI configuration.

About backward compatibility

This feature is backward compatible. The addition of integration tests and the configuration of Redis instances for testing purposes do not affect existing functionalities. All current interfaces and behaviors remain unchanged. The integration tests enhance the testing suite without modifying any production code, ensuring that existing users and systems are not impacted.
