Chapter 9: Skipping Testing

1. Write the test first using test-driven design and automate the test execution.
2. Minimize end-to-end tests using techniques such as journeys, which test the user journey through the system.
3. Use contract testing to mock and stub out integration tests.
4. Focus on the critical parts of the system first. 
5. Testing using the shift-left approach by testing early and employing unit testing and integration tests and load testing will give a high level of confidence that our microservices will provide a pleasant user experience for our users and meet the needs of the business.
