// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.//// Example Usage//// The following is a complete example using assert in a standard test function://    import (//      "testing"//      "github.com/stretchr/testify/assert"//    )////    func TestSomething(t *testing.T) {////      var a string = "Hello"//      var b string = "Hello"////      assert.Equal(t, a, b, "The two words should be the same.")////    }//// if you assert many times, use the format below:////    import (//      "testing"//      "github.com/stretchr/testify/assert"//    )////    func TestSomething(t *testing.T) {//      assert := assert.New(t)////      var a string = "Hello"//      var b string = "Hello"////      assert.Equal(a, b, "The two words should be the same.")//    }//// Assertions//// Assertions allow you to easily write test code, and are global funcs in the `assert` package.// All assertion functions take, as the first argument, the `*testing.T` object provided by the// testing framework. This allows the assertion funcs to write the failings and other details to// the correct place.//// 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 assert
