Graphology Assertions

Assertions to be used with graphology.

Installation 

npm install graphology-assertions

Usage

#.isGraph

Function returning whether the given value is a graphology implementation’s instance.

import {isGraph} from 'graphology-assertions';

const graph = new Graph();

isGraph(graph);
>>> true

isGraph(45);
>>> false

isGraph({hello: 'world'});
>>> false

Arguments

  • value any: value to test.

#.isGraphConstructor

Function returning whether the given value is a graphology constructor.

import {isGraphConstructor} from 'graphology-assertions';

isGraphConstructor(Graph);
>>> true

isGraphConstructor(45);
>>> false

isGraphConstructor(new Graph());
>>> false

Arguments

  • value any: value to test.

#.haveSameNodes

Returns whether two graphs have the same nodes.

import {haveSameNodes} from 'graphology-assertions';

haveSameNodes(G, H);

#.haveSameNodesDeep

Returns whether two graphs have the same nodes & whether those nodes have the same attributes.

import {haveSameNodesDeep} from 'graphology-assertions';

haveSameNodesDeep(G, H);

#.areSameGraphs

Returns whether two graphs are the same.

import {areSameGraphs} from 'graphology-assertions';

areSameGraphs(G, H);

#.areSameGraphsDeep

Returns whether two graphs as well as their node & edge attributes are the same.

import {areSameGraphsDeep} from 'graphology-assertions';

areSameGraphsDeep(G, H);

#.haveSameEdges

Returns whether two graphs have the same edges. Note that it implies that both graphs’ nodes are also the same.

This is different than areSameGraphs because it will allow different graph types to be compared, e.g. a mixed graph and a directed one having the same edges nonetheless.

import {haveSameEdges} from 'graphology-assertions';

haveSameEdges(G, H);

#.haveSameEdgesDeep

Returns whether two graphs have the same edges & whether those edges have the same attributes. Note that it implies that both graphs’ nodes are also the same.

This is different than areSameGraphsDeep because it will allow different graph types to be compared, e.g. a mixed graph and a directed one having the same edges nonetheless.

import {haveSameEdgesDeep} from 'graphology-assertions';

haveSameEdgesDeep(G, H);
