+// 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.

+// Package suite contains logic for creating testing suite structs

+// or individual tests (depending on which interface(s) you
+// implement).
+//
+// A testing suite is usually built by first extending the built-in
+// suite functionality from suite.Suite in testify.  Alternatively,
+// you could reproduce that logic on your own if you wanted (you
+// just need to implement the TestingSuite interface from
+// suite/interfaces.go).
+//
+// After that, you can implement any of the interfaces in
+// suite/interfaces.go to add setup/teardown functionality to your
+// suite, and add any methods that start with "Test" to add tests.
+// Methods that do not match any suite interfaces and do not begin
+// with "Test" will not be run by testify, and can safely be used as
+// helper methods.
+//
+// Once you've built your testing suite, you need to run the suite
+// (using suite.Run from testify) inside any function that matches the
+// identity that "go test" is already looking for (i.e.
+// func(*testing.T)).
