Test-driven development (TDD) is a software design technique based on tests that promotes an iterative way of writing software. This course will teach you to use TDD using Go—one of the most popular languages.

In this course, you will first learn about the fundamentals of Go, including packages, standard library, and error handling. Then, you will go through a comprehensive guide on writing test cases using Go, including subtests, table-driven tests, skipping, benchmarking, fuzzing, dependency injection, and mocking in unit tests. Next, you will look at multiple TDD katas and learn about the best practices for making most of the TDD approach. Finally, you will build a TODO application by following the test-driven development approach. This application will be a REST API that exposes actions getting TODOs. 

After completing this course, you will have the skills needed to build reliable applications using the test-driven development approach.

Learning Test-Driven Development with Go

So far, our `Validate` function has been limited since it can only handle the scenario where the input password is shorter than eight characters. Let’s enrich it with a new requirement.
## At least two digits requirement
This requirement states that the password is valid only if it has at least two digits among its characters. If this requirement is not met, the function has to return `the password must contain at least 2 numbers` error. 
### The Red phase
To enter into the Red phase, we'll write a test for the value `abcdefgh1`:
