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.

be equal in both declarations.
