What activity in Continuous Integration involves validating the solution?

1. Deploy

2. Test end-to-end

3. Stage

4. Verify

The correct answer is: Test end-to-end

Validating the solution in the context of Continuous Integration (CI) is primarily achieved through testing, which encompasses various forms of testing to ensure that the code meets the expected requirements and functions correctly. Testing end-to-end is particularly crucial as it assesses the entire workflow, simulating real user scenarios to ensure that all components of the software work together seamlessly. End-to-end testing involves not just unit or integration tests, but a holistic approach that checks the application from the user’s perspective. This ensures that the solution works as intended in a production-like environment. Therefore, when the question refers to the activity in CI that specifically pertains to validating the solution, it is highlighting the importance of comprehensive testing measures, which is best captured by 'test end-to-end.' Other activities, such as deploying or verifying, may play roles in the development and deployment pipeline, but they do not specifically focus on the validation aspect as explicitly as end-to-end testing does. Staging refers to preparing the application for deployment but does not inherently involve validation of the solution itself.
