Building Microservices API in Go - Unit Testing: State-Based Test

The video tutorial covers the process of writing unit tests in Golang, emphasizing the importance of testing before production code. It explains the concept of a unit, demonstrates creating test files, and introduces the AAA (Arrange-Act-Assert) testing format. The tutorial also covers state-based testing, refactoring with tests, and testing transaction request validations, focusing on transaction types and amounts.

What is the primary focus when writing unit tests for an application?

• Focusing only on the user interface

• Ignoring the backend logic

• Testing the entire application at once

• Writing tests for routes, services, DTOs, and domain objects

What is a 'unit' in the context of unit testing?

• The smallest piece of code that can be logically isolated

• The entire application

• A group of related functions

• A single line of code

Why is it important to have shorter feedback cycles in testing?

• To reduce the number of tests

• To quickly identify and fix issues

• To avoid writing any tests

• To increase the complexity of tests

What should be the focus when testing transaction requests?

• The transaction type and amount

• The database schema

• The user interface

• The network latency

What does the AAA format stand for in test writing?

• Arrange, Act, Assert

• Analyze, Act, Assert

• Arrange, Analyze, Assert

• Act, Arrange, Assert

In Golang, how are assertions typically handled in tests?

• Using a built-in assertion library

• Using a graphical interface

• Using if conditions

• Using external plugins

What is the benefit of naming test functions descriptively?

• It confuses the developers

• It makes the code longer

• It helps in identifying the purpose of the test easily

• It has no real benefit

What is the expected error code for an unprocessable entity in the test?

• 500

• 422

• 404

• 200

What is the purpose of refactoring code with the help of unit tests?

• To test the impact of changes quickly

• To remove all tests

• To ensure the code is error-free

• To make the code more complex

Why is it beneficial to give a name to conditions in tests?

• To increase the number of lines

• To improve readability and understanding

• To confuse other developers

• To make the code more complex
