Go run main.go-Simple

In this course you will learn why Go is an awesome language for writing command-line programs. You will learn how to structure your Go programs, how to write idiomatic Go code, how to test your programs and how to amaze your users, peers and managers. 

The focus is on command-line programs in order to keep the course down to earth, but most of the principles and best practices you will learn apply to any Go program.

Write Professional Command-line Programs in Go


## Running tests with go test

Now that we have some tests, let's run them.

### Running functional tests

Running Go tests is very easy. Just type `go test`. If you want a little more verbose output that lists the tests being run, type `go test -v`. If you run the test below, you'll see this output:

```
=== RUN   TestCalcAreaSuccess
--- PASS: TestCalcAreaSuccess (0.00s)
=== RUN   TestCalcAreaFail
--- PASS: TestCalcAreaFail (0.00s)
=== RUN   TestCalcAreaViaTable
--- PASS: TestCalcAreaViaTable (0.00s)
PASS
ok  	_/usercode	0.003s
```
