示例1: suite
suite('Graph', () => {
let graph: Graph<string>;
setup(() => {
graph = new Graph<string>(s => s);
});
test('is possible to lookup nodes that don\'t exist', function () {
assert.deepEqual(graph.lookup('ddd'), null);
});
test('inserts nodes when not there yet', function () {
assert.deepEqual(graph.lookup('ddd'), null);
assert.deepEqual(graph.lookupOrInsertNode('ddd').data, 'ddd');
assert.deepEqual(graph.lookup('ddd').data, 'ddd');
});
test('can remove nodes and get length', function () {
assert.ok(graph.isEmpty());
assert.deepEqual(graph.lookup('ddd'), null);
assert.deepEqual(graph.lookupOrInsertNode('ddd').data, 'ddd');
assert.ok(!graph.isEmpty());
graph.removeNode('ddd');
assert.deepEqual(graph.lookup('ddd'), null);
assert.ok(graph.isEmpty());
});
test('root', () => {
graph.insertEdge('1', '2');
let roots = graph.roots();
assert.equal(roots.length, 1);
assert.equal(roots[0].data, '2');
graph.insertEdge('2', '1');
roots = graph.roots();
assert.equal(roots.length, 0);
});
test('root complex', function () {
graph.insertEdge('1', '2');
graph.insertEdge('1', '3');
graph.insertEdge('3', '4');
let roots = graph.roots();
assert.equal(roots.length, 2);
assert(['2', '4'].every(n => roots.some(node => node.data === n)));
});
});示例2: function
test('root complex', function () {
graph.insertEdge('1', '2');
graph.insertEdge('1', '3');
graph.insertEdge('3', '4');
let roots = graph.roots();
assert.equal(roots.length, 2);
assert(['2', '4'].every(n => roots.some(node => node.data === n)));
});示例3:
test('root', () => {
graph.insertEdge('1', '2');
let roots = graph.roots();
assert.equal(roots.length, 1);
assert.equal(roots[0].data, '2');
graph.insertEdge('2', '1');
