Go: Building Web Applications

Using Go with unit testing

As with many of the basic and intermediate development and deployment requirements you may have, Go comes with a built-in application for handling unit tests.

The basic premise behind testing is that you create your package and then create a testing package to run against the initial application. The following is a very basic example:

mathematics.go
package mathematics

  return x * 3
}
mathematics_test.go

)

func Test_Square_1(t *testing.T) {
  if Square(2) != 4 {
