GOSample

For go in-built unit testing steps:

1. Create file with name like <extingfilename>_test.go (ex. for sort.go test filename will be sort_test.go)
2. add import "testing" package
3. Add method with prefix Test and having parameter t testing.T 
    ex : (func TestBubbleSortNoError(t *testing.T))
4. add validations : Example
    //validation
    if elements[0] != 9 {
        t.Error("first element should not be 9")
    }

Commands using with this project

1.  go test -cover     (inside folder)
2.   go test -bench=.

Benchmark: Create function Name starting with Benchmark (example: func BenchmarkSort(t *testing.B){ for i = 0 ; i < b.N ; i++{} })
