6. Unit Testing

GO offers its own package that allows programmers to
create unit test cases
• Test functions in your package by using,
$ go test <package_name>

7. Errors in GO
• Most of the built in functions return an error
variable along with expected return values
f, err := os.Open("filename.ext")
• For user defined functions, you can create your
own errors and return them
return yourval, errors.New(“Your error")

written before each function in a package
