Gomega's format package pretty-prints objects. It explores input objects recursively and generates formatted, indented output with type information.

    var Indent = "    "

      The default indentation string emitted by the format package

      View Source
      var MaxDepth = uint(10)

        Use MaxDepth to set the maximum recursion depth when printing deeply nested objects

        View Source
        var UseStringerRepresentation = false

          By default, all objects (even those that implement fmt.Stringer and fmt.GoStringer) are recursively inspected to generate output.

          Set UseStringerRepresentation = true to use GoString (for fmt.GoStringers) or String (for fmt.Stringer) instead.

          Note that GoString and String don't always have all the information you need to understand why a test failed!


          func IndentString

          func IndentString(s string, indentation uint) string

            IndentString takes a string and indents each line by the specified amount.

            func Message

            func Message(actual interface{}, message string, expected ...interface{}) string

              Generates a formatted matcher success/failure message of the form:

              	<pretty printed actual>
              	<pretty printed expected>

              If expected is omited, then the message looks like:

              	<pretty printed actual>

              func Object

              func Object(object interface{}, indentation uint) string

                Pretty prints the passed in object at the passed in indentation level.

                Object recurses into deeply nested objects emitting pretty-printed representations of their components.

                Modify format.MaxDepth to control how deep the recursion is allowed to go Set format.UseStringerRepresentation to true to return object.GoString() or object.String() when available instead of recursing into the object.
