Distributed Computing with Go

variadic_test.go

We would like to test the two valid functions, simpleVariadicToSlice and mixedVariadicToSlice, for various rules defined in the previous section. However, for the sake of brevity, we will test these:

• simpleVariadicToSlice: This is for no arguments, three arguments, and also to look at how to pass a slice to a variadic function
• mixedVariadicToSlice: This is to accept a simple argument and a variadic argument

Let's now look at the code to test these two functions:

// variadic_test.go package main import "testing" func TestSimpleVariadicToSlice(t *testing.T) { // Test for no arguments if val := simpleVariadicToSlice(); val != nil { t.Error("value should be nil", nil) } else { t.Log("simpleVariadicToSlice() -> nil") } // Test ...
