+Testify - Thou Shalt Write Tests
+================================
+
+[![Build Status](https://travis-ci.org/stretchr/testify.svg)](https://travis-ci.org/stretchr/testify) [![Go Report Card](https://goreportcard.com/badge/github.com/stretchr/testify)](https://goreportcard.com/report/github.com/stretchr/testify) [![GoDoc](https://godoc.org/github.com/stretchr/testify?status.svg)](https://godoc.org/github.com/stretchr/testify)
+
+Go code (golang) set of packages that provide many tools for testifying that your code will behave as you intend.
+
+Features include:
+
+  * [Easy assertions](#assert-package)
+  * [Mocking](#mock-package)
+  * [HTTP response trapping](#http-package)
+  * [Testing suite interfaces and functions](#suite-package)
+
+Get started:
+
+  * Install testify with [one line of code](#installation), or [update it with another](#staying-up-to-date)
+  * For an introduction to writing test code in Go, see http://golang.org/doc/code.html#Testing
+  * Check out the API Documentation http://godoc.org/github.com/stretchr/testify
+  * To make your testing life easier, check out our other project, [gorc](http://github.com/stretchr/gorc)
+  * A little about [Test-Driven Development (TDD)](http://en.wikipedia.org/wiki/Test-driven_development)
+
+
+
+[`assert`](http://godoc.org/github.com/stretchr/testify/assert "API documentation") package
+-------------------------------------------------------------------------------------------
+
+The `assert` package provides some helpful methods that allow you to write better test code in Go.
+
+  * Prints friendly, easy to read failure descriptions
+  * Allows for very readable code
+  * Optionally annotate each assertion with a message
+
+See it in action:
+
+```go
+package yours
+
+import (
+  "testing"
+  "github.com/stretchr/testify/assert"
+)
+
+func TestSomething(t *testing.T) {
+
+  // assert equality
+  assert.Equal(t, 123, 123, "they should be equal")
+
+  // assert inequality
+  assert.NotEqual(t, 123, 456, "they should not be equal")
+
+  // assert for nil (good for errors)
+  assert.Nil(t, object)
+
+  // assert for not nil (good when you expect something)
+  if assert.NotNil(t, object) {
+
+    // now we know that object isn't nil, we are safe to make
+    // further assertions without causing any errors
+    assert.Equal(t, "Something", object.Value)
+
+  }
+
+}
+```
+
+  * Every assert func takes the `testing.T` object as the first argument.  This is how it writes the errors out through the normal `go test` capabilities.
+  * Every assert func returns a bool indicating whether the assertion was successful or not, this is useful for if you want to go on making further assertions under certain conditions.
+
+if you assert many times, use the below:
+
+```go
+package yours
+
+import (
+  "testing"
+  "github.com/stretchr/testify/assert"
+)
+
+func TestSomething(t *testing.T) {
+  assert := assert.New(t)
+
+  // assert equality
+  assert.Equal(123, 123, "they should be equal")
+
+  // assert inequality
+  assert.NotEqual(123, 456, "they should not be equal")
+
+  // assert for nil (good for errors)
+  assert.Nil(object)
+
+  // assert for not nil (good when you expect something)
+  if assert.NotNil(object) {
+
+    // now we know that object isn't nil, we are safe to make
+    // further assertions without causing any errors
+    assert.Equal("Something", object.Value)
+  }
+}
+```
+
+[`require`](http://godoc.org/github.com/stretchr/testify/require "API documentation") package
+---------------------------------------------------------------------------------------------
+
+The `require` package provides same global functions as the `assert` package, but instead of returning a boolean result they terminate current test.
+
+See [t.FailNow](http://golang.org/pkg/testing/#T.FailNow) for details.
+
+
+[`http`](http://godoc.org/github.com/stretchr/testify/http "API documentation") package
+---------------------------------------------------------------------------------------
+
+The `http` package contains test objects useful for testing code that relies on the `net/http` package.  Check out the [(deprecated) API documentation for the `http` package](http://godoc.org/github.com/stretchr/testify/http).
+
+We recommend you use [httptest](http://golang.org/pkg/net/http/httptest) instead.
+
+[`mock`](http://godoc.org/github.com/stretchr/testify/mock "API documentation") package
+----------------------------------------------------------------------------------------
+
+The `mock` package provides a mechanism for easily writing mock objects that can be used in place of real objects when writing test code.
+
+An example test function that tests a piece of code that relies on an external object `testObj`, can setup expectations (testify) and assert that they indeed happened:
+
+```go
+package yours
+
+import (
+  "testing"
+  "github.com/stretchr/testify/mock"
+)
+
+/*
+  Test objects
+*/
+
+// MyMockedObject is a mocked object that implements an interface
+// that describes an object that the code I am testing relies on.
+type MyMockedObject struct{
+  mock.Mock
+}
+
+// DoSomething is a method on MyMockedObject that implements some interface
+// and just records the activity, and returns what the Mock object tells it to.
+//
+// In the real object, this method would do something useful, but since this
+// is a mocked object - we're just going to stub it out.
+//
+// NOTE: This method is not being tested here, code that uses this object is.
+func (m *MyMockedObject) DoSomething(number int) (bool, error) {
+
+  args := m.Called(number)
+  return args.Bool(0), args.Error(1)
+
+}
+
+/*
+  Actual test functions
+*/
+
+// TestSomething is an example of how to use our test object to
+// make assertions about some target code we are testing.
+func TestSomething(t *testing.T) {
+
+  // create an instance of our test object
+  testObj := new(MyMockedObject)
+
+  // setup expectations
+  testObj.On("DoSomething", 123).Return(true, nil)
+
+  // call the code we are testing
+  targetFuncThatDoesSomethingWithObj(testObj)
+
+  // assert that the expectations were met
+  testObj.AssertExpectations(t)
+
+}
+```
+
+For more information on how to write mock code, check out the [API documentation for the `mock` package](http://godoc.org/github.com/stretchr/testify/mock).
+
+You can use the [mockery tool](http://github.com/vektra/mockery) to autogenerate the mock code against an interface as well, making using mocks much quicker.
+
+[`suite`](http://godoc.org/github.com/stretchr/testify/suite "API documentation") package
+-----------------------------------------------------------------------------------------
+
+The `suite` package provides functionality that you might be used to from more common object oriented languages.  With it, you can build a testing suite as a struct, build setup/teardown methods and testing methods on your struct, and run them with 'go test' as per normal.
+
+An example suite is shown below:
+
+```go
+// Basic imports
+import (
+    "testing"
+    "github.com/stretchr/testify/assert"
+    "github.com/stretchr/testify/suite"
+)
+
+// Define the suite, and absorb the built-in basic suite
+// functionality from testify - including a T() method which
+// returns the current testing context
+type ExampleTestSuite struct {
+    suite.Suite
+    VariableThatShouldStartAtFive int
+}
+
+// Make sure that VariableThatShouldStartAtFive is set to five
+// before each test
+func (suite *ExampleTestSuite) SetupTest() {
+    suite.VariableThatShouldStartAtFive = 5
+}
+
+// All methods that begin with "Test" are run as tests within a
+// suite.
+func (suite *ExampleTestSuite) TestExample() {
+    assert.Equal(suite.T(), 5, suite.VariableThatShouldStartAtFive)
+}
+
+// In order for 'go test' to run this suite, we need to create
+// a normal test function and pass our suite to suite.Run
+func TestExampleTestSuite(t *testing.T) {
+    suite.Run(t, new(ExampleTestSuite))
+}
+```
+
+For a more complete example, using all of the functionality provided by the suite package, look at our [example testing suite](https://github.com/stretchr/testify/blob/master/suite/suite_test.go)
+
+For more information on writing suites, check out the [API documentation for the `suite` package](http://godoc.org/github.com/stretchr/testify/suite).
+
+`Suite` object has assertion methods:
+
+```go
+// Basic imports
+import (
+    "testing"
+    "github.com/stretchr/testify/suite"
+)
+
+// Define the suite, and absorb the built-in basic suite
+// functionality from testify - including assertion methods.
+type ExampleTestSuite struct {
+    suite.Suite
+    VariableThatShouldStartAtFive int
+}
+
+// Make sure that VariableThatShouldStartAtFive is set to five
+// before each test
+func (suite *ExampleTestSuite) SetupTest() {
+    suite.VariableThatShouldStartAtFive = 5
+}
+
+// All methods that begin with "Test" are run as tests within a
+// suite.
+func (suite *ExampleTestSuite) TestExample() {
+    suite.Equal(suite.VariableThatShouldStartAtFive, 5)
+}
+
+// In order for 'go test' to run this suite, we need to create
+// a normal test function and pass our suite to suite.Run
+func TestExampleTestSuite(t *testing.T) {
+    suite.Run(t, new(ExampleTestSuite))
+}
+```

+// 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 mock provides a system by which it is possible to mock your objects
+// and verify calls are happening as expected.
+//
+// Example Usage
+//
+// The mock package provides an object, Mock, that tracks activity on another object.  It is usually
+// embedded into a test object as shown below:
+//
+//   type MyTestObject struct {
+//     // add a Mock object instance
+//     mock.Mock
+//
+//     // other fields go here as normal
+//   }
+//
+// When implementing the methods of an interface, you wire your functions up
+// to call the Mock.Called(args...) method, and return the appropriate values.
+//
+// For example, to mock a method that saves the name and age of a person and returns
+// the year of their birth or an error, you might write this:
+//
+//     func (o *MyTestObject) SavePersonDetails(firstname, lastname string, age int) (int, error) {
+//       args := o.Called(firstname, lastname, age)
+//       return args.Int(0), args.Error(1)
+//     }
+//
+// The Int, Error and Bool methods are examples of strongly typed getters that take the argument
+// index position. Given this argument list:
+//
+//     (12, true, "Something")
+//
+// You could read them out strongly typed like this:
+//
+//     args.Int(0)
+//     args.Bool(1)
+//     args.String(2)
+//
+// For objects of your own type, use the generic Arguments.Get(index) method and make a type assertion:
+//
+//     return args.Get(0).(*MyObject), args.Get(1).(*AnotherObjectOfMine)
+//
+// This may cause a panic if the object you are getting is nil (the type assertion will fail), in those
+// cases you should check for nil first.

+// 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,

+// Package suite contains logic for creating testing suite structs
+// and running the methods on those structs as tests.  The most useful
+// piece of this package is that you can create setup/teardown methods
+// on your testing suites, which will run before/after the whole suite
+// 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)).
+//
+// Regular expression to select test suites specified command-line
+// argument "-run". Regular expression to select the methods
+// of test suites specified command-line argument "-m".

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+	* Pointers are dereferenced and followed
+	* Circular data structures are detected and handled properly
+	* Custom Stringer/error interfaces are optionally invoked, including
+	  on unexported types
+	* Custom types which only implement the Stringer/error interfaces via
+	  a pointer receiver are optionally invoked when passing non-pointer
+	  variables
+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output (only when using
+	  Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+	* Dump style which prints with newlines, customizable indentation,
+	  and additional debug information such as types and all pointer addresses
+	  used to indirect to the final value
+	* A custom Formatter interface that integrates cleanly with the standard fmt
+	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+	  similar to the default %v while providing the additional functionality
+	  outlined above and passing unsupported format verbs such as %x and %q
+	  along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew.  See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+	spew.Dump(myVar1, myVar2, ...)
+	spew.Fdump(someWriter, myVar1, myVar2, ...)
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type.  For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions.  This allows concurrent configuration
+options.  See the ConfigState documentation for more details.
+
+The following configuration options are available:
+	* Indent
+		String to use for each indentation level for Dump functions.
+		It is a single space by default.  A popular alternative is "\t".
+
+	* MaxDepth
+		Maximum number of levels to descend into nested data structures.
+		There is no limit by default.
+
+	* DisableMethods
+		Disables invocation of error and Stringer interface methods.
+		Method invocation is enabled by default.
+
+	* DisablePointerMethods
+		Disables invocation of error and Stringer interface methods on types
+		which only accept pointer receivers from non-pointer variables.
+		Pointer method invocation is enabled by default.
+
+	* ContinueOnMethod
+		Enables recursion into types after invoking error and Stringer interface
+		methods. Recursion after method invocation is disabled by default.
+
+	* SortKeys
+		Specifies map keys should be sorted before being printed. Use
+		this to have a more deterministic, diffable output.  Note that
+		only native types (bool, int, uint, floats, uintptr and string)
+		and types which implement error or Stringer interfaces are
+		supported with other types sorted according to the
+		reflect.Value.String() output which guarantees display
+		stability.  Natural map order is used by default.
+
+	* SpewKeys
+		Specifies that, as a last resort attempt, map keys should be
+		spewed to strings and sorted by those strings.  This is only
+		considered if SortKeys is true.
+
+Dump Usage
+
+Simply call spew.Dump with a list of variables you want to dump:
+
+	spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer.  For example, to dump to standard error:
+
+	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
+
+A third option is to call spew.Sdump to get the formatted output as a string:
+
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Sample Dump Output
+
+See the Dump example for details on the setup of the types and variables being
+shown here.
+
+	(main.Foo) {
+	 unexportedField: (*main.Bar)(0xf84002e210)({
+	  flag: (main.Flag) flagTwo,
+	  data: (uintptr) <nil>
+	 }),
+	 ExportedField: (map[interface {}]interface {}) (len=1) {
+	  (string) (len=3) "one": (bool) true
+	 }
+	}
+
+Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
+command as shown.

+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
+functions have syntax you are most likely already familiar with:
+
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Println(myVar, myVar2)
+	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output.  Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+// published in the late 1980's by Ratcliff and Obershelp under the
+// hyperbolic name "gestalt pattern matching".  The basic idea is to find
+// the longest contiguous matching subsequence that contains no "junk"
+// elements (R-O doesn't address junk).  The same idea is then applied
+// recursively to the pieces of the sequences to the left and to the right
+// of the matching subsequence.  This does not yield minimal edit
+// sequences, but does tend to yield matches that "look right" to people.
+//
+// SequenceMatcher tries to compute a "human-friendly diff" between two
+// sequences.  Unlike e.g. UNIX(tm) diff, the fundamental notion is the
+// longest *contiguous* & junk-free matching subsequence.  That's what
+// catches peoples' eyes.  The Windows(tm) windiff has another interesting
+// notion, pairing up elements that appear uniquely in each sequence.
+// That, and the method here, appear to yield more intuitive difference
+// reports than does diff.  This method appears to be the least vulnerable
+// to synching up on blocks of "junk lines", though (like blank lines in
+// ordinary text files, or maybe "<P>" lines in HTML files).  That may be
+// because this is the only method of the 3 that has a *concept* of
+// "junk" <wink>.
+//
+// Timing:  Basic R-O is cubic time worst case and quadratic time expected
+// case.  SequenceMatcher is quadratic time for the worst case and has
+// expected-case behavior dependent in a complicated way on how many
+// elements the sequences have in common; best case time is linear.

+// objx - Go package for dealing with maps, slices, JSON and other data.
+//
+// Overview
+//
+// Objx provides the `objx.Map` type, which is a `map[string]interface{}` that exposes
+// a powerful `Get` method (among others) that allows you to easily and quickly get
+// access to data within the map, without having to worry too much about type assertions,
+// missing data, default values etc.
+//
+// Pattern
+//
+// Objx uses a preditable pattern to make access data from within `map[string]interface{}'s
+// easy.
+//
+// Call one of the `objx.` functions to create your `objx.Map` to get going:
+//
+//     m, err := objx.FromJSON(json)
+//
+// NOTE: Any methods or functions with the `Must` prefix will panic if something goes wrong,
+// the rest will be optimistic and try to figure things out without panicking.
+//
+// Use `Get` to access the value you're interested in.  You can use dot and array
+// notation too:
+//
+//     m.Get("places[0].latlng")
+//
+// Once you have saught the `Value` you're interested in, you can use the `Is*` methods
+// to determine its type.
+//
+//     if m.Get("code").IsStr() { /* ... */ }
+//
+// Or you can just assume the type, and use one of the strong type methods to
+// extract the real value:
+//
+//     m.Get("code").Int()
+//
+// If there's no value there (or if it's the wrong type) then a default value
+// will be returned, or you can be explicit about the default value.
+//
+//     Get("code").Int(-1)
+//
+// If you're dealing with a slice of data as a value, Objx provides many useful
+// methods for iterating, manipulating and selecting that data.  You can find out more
+// by exploring the index below.
+//
+// Reading data
+//
+// A simple example of how to use Objx:
+//
+//     // use MustFromJSON to make an objx.Map from some JSON
+//     m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
+//
+//     // get the details
+//     name := m.Get("name").Str()
+//     age := m.Get("age").Int()
+//
+//     // get their nickname (or use their name if they
+//     // don't have one)
+//     nickname := m.Get("nickname").Str(name)
+//
+// Ranging
+//
+// Since `objx.Map` is a `map[string]interface{}` you can treat it as such.  For
+// example, to `range` the data, do what you would expect:
+//
+//     m := objx.MustFromJSON(json)
+//     for key, value := range m {
+//
+//       /* ... do your magic ... */
+//
+//     }
