Testing in Go

Test functions in Go

A test in Go must satisfy the following requirements

• The containing file must have a name ending in _test.go.
• The function name must begin with Test.
• The function must have a parameter of type *testing.T.
• The function must have no return value.

Here's an example of a testing function:

Sample test function in Go

func TestAdd(t *testing.T) {
    t.Parallel()
    var expected float64 = 16
    Actual := calculator.Add(7, 9)
    if expected != Actual {
        t.Errorf("Expected %f, Actual %f", want, got)
    }
}
