Functions

func AddElement

func AddElement(t *testing.T, g construct.Graph, e any) (failed bool)

AddElement is a utility function for adding an element to a graph. See MakeGraph for more information on supported element types. Returns whether adding the element failed.

func AssertGraphContains

func AssertGraphContains(t *testing.T, expect, actual construct.Graph)

func AssertGraphEqual

func AssertGraphEqual(t *testing.T, expect, actual construct.Graph, message string, args ...any)

func MakeGraph

func MakeGraph(t *testing.T, g construct.Graph, elements ...any) construct.Graph

MakeGraph is a utility function for creating a graph from a list of elements which can be of types: - ResourceId : adds an empty resource with the given ID - Resource, *Resource : adds the given resource - Edge : adds the given edge - Path : adds all the edges in the path - string : parses the string as either a ResourceId or an Edge and add it as above

The input graph is so it can be either via NewGraph or NewAcyclicGraph. Users are encouraged to wrap this function for the specific test function for ease of use, such as:

makeGraph := func(elements ...any) Graph {
	return MakeGraph(t, NewGraph(), elements...)
}
