示例1: it
it("sets proper document on models added during patching", () => {
const d = new Document()
expect(d.roots().length).to.equal(0)
expect(Object.keys(d._all_models).length).to.equal(0)
const root1 = new SomeModel({ foo: 42 })
const child1 = new SomeModel({ foo: 44 })
d.add_root(root1)
expect(d.roots().length).to.equal(1)
// can't create copy of doc here like other test. Testing explicitly that
// doc attach happens when *not* creating a new document (i.e only patching)
// Testing only for/against null .document is not the strongest test but it
// should suffice.
expect(root1.document!.roots().length).equal(1)
expect(root1.child).to.equal(null)
const event1 = new ev.ModelChangedEvent(d, root1, 'child', root1.child, child1)
const patch1 = d.create_json_patch_string([event1])
d.apply_json_patch(JSON.parse(patch1))
expect(root1.document!.roots().length).equal(1)
expect(root1.child!.document!.roots().length).equal(1)
