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

So is a convenience 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)
}
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.
