Building Microservices API in Go - Unit Testing: Testing Services

The video tutorial covers testing the new account service, focusing on creating and configuring mocks, defining test scenarios, and executing tests. It emphasizes the importance of testing for validation errors, server-side errors, and successful responses. The tutorial also includes refactoring for better code readability and concludes with the significance of testing in maintaining code quality.

What is the primary focus of testing the new account service?

• Testing the user interface

• Testing the account repository

• Testing the dependency on the account repository

• Testing the database connection

Which component is mocked in the new account service tests?

• Network layer

• User interface

• Account repository

• Database

What is the first scenario to test in the new account service?

• Validation error response

• Successful account creation

• Network failure

• Server-side error

In the first test case, what is the expected outcome if the validation fails?

• No response

• A server-side error

• A validation error response

• A successful account creation

What is the purpose of mocking in the second test case?

• To simulate network latency

• To simulate a user interface

• To simulate database connection

• To simulate server-side errors

What is the expected result when the server-side error is simulated?

• A successful account creation

• A validation error

• An error from the server

• No response

What is the focus of the final test case?

• Server-side errors

• Network issues

• Validation errors

• Successful account creation

What is the benefit of having a good set of tests according to the video?

• Improved network speed

• Better user interface

• Easier code refactoring

• Faster code execution

What is emphasized as an investment in the video?

• User interface design

• Database optimization

• Network infrastructure

• Testing

What does the video suggest about the quality of code with proper testing?

• It becomes slower

• It remains the same

• It is always maintained

• It becomes less readable
