Robert Zaremba 5d895db2fd vendor: add github.com/stretchr/testify test dependency
github.com/stretchr/testify is a useful library for doing
assertion in tests. It makes assertions in test more less verbose and
more comfortable to read and use.

// Package require implements the same assertions as the `assert` package but
// stops test execution when a test fails.
//
// Example Usage
//
// The following is a complete example using require in a standard test function:
// import (
// "testing"
// "github.com/stretchr/testify/require"
// )
//
// func TestSomething(t *testing.T) {
//
// var a string = "Hello"
// var b string = "Hello"
//
// require.Equal(t, a, b, "The two words should be the same.")
//
// }
//
// Assertions
//
// The `require` package have same global functions as in the `assert` package,
// but instead of returning a boolean result they call `t.FailNow()`.
//
// Every assertion function also takes an optional string message as the final argument,
// allowing custom error messages to be appended to the message the assertion method outputs.
