# 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) for use with the So(...) method. They
can also be used in traditional Go test functions and even in applicaitons.

## Usage

#### func  GoConveyMode

```go
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  ShouldAlmostEqual

equal. The acceptable delta may be specified with a third argument, or a very
small default delta will be used.

#### func  So

```go
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

```go
type Assertion struct {
}
```


#### func  New

```go
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

```go
func (this *Assertion) Failed() bool
```
Failed reports whether any calls to So (on this Assertion instance) have failed.

#### func (*Assertion) So

```go
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 Serializer

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