assertions

-- import "github.com/smartystreets/assertions"

Package assertions contains the implementations for all assertions which are referenced in goconvey's convey package (github.com/smartystreets/goconvey/convey) and gunit (github.com/smartystreets/gunit) for use with the So(...) method. They can also be used in traditional Go test functions and even in applications.

Many of the assertions lean heavily on work done by Aaron Jacobs in his excellent oglematchers library. (https://github.com/jacobsa/oglematchers) The ShouldResemble assertion leans heavily on work done by Daniel Jacques in his very helpful go-render library. (https://github.com/luci/go-render)

Usage

func GoConveyMode

func GoConveyMode(yes bool)

GoConveyMode provides control over JSON serialization of failures. When using the assertions in this package from the convey package JSON results are very helpful and can be rendered in a DIFF view. In that case, this function will be called with a true value to enable the JSON serialization. By default, the assertions in this package will not serializer a JSON result, making standalone ussage more convenient.

func So

func So(actual interface{}, assert assertion, expected ...interface{}) (bool, string)

So is a convenience function (as opposed to an inconvenience function?) for running assertions on arbitrary arguments in any context, be it for testing or even application logging. It allows you to perform assertion-like behavior (and get nicely formatted messages detailing discrepancies) but without the program blowing up or panicking. All that is required is to import this package and call So with one of the assertions exported by this package as the second parameter. The first return parameter is a boolean indicating if the assertion was true. The second return parameter is the well-formatted message showing why an assertion was incorrect, or blank if the assertion was correct.

Example:

if ok, message := So(x, ShouldBeGreaterThan, y); !ok {
     log.Println(message)
}

type Assertion

type Assertion struct {
}

func New

func New(t testingT) *Assertion

New swallows the *testing.T struct and prints failed assertions using t.Error. Example: assertions.New(t).So(1, should.Equal, 1)

func (*Assertion) Failed

Failed reports whether any calls to So (on this Assertion instance) have failed.

func (*Assertion) So

func (this *Assertion) So(actual interface{}, assert assertion, expected ...interface{}) bool

So calls the standalone So function and additionally, calls t.Error in failure scenarios.

type FailureView

type FailureView struct {
	Message  string `json:"Message"`
	Expected string `json:"Expected"`
	Actual   string `json:"Actual"`
}

This struct is also declared in github.com/smartystreets/goconvey/convey/reporting. The json struct tags should be equal in both declarations.

type Serializer

type Serializer interface {
	// contains filtered or unexported methods
}
