Company Model Structure Challenge
Amazing Co for example needs to model how her company is structured so they can do awesome stuff. They have a root node (only one) and several children nodes, each one with its own children as well. It's a tree-based structure.

A node can be added in a Tree which automatically adds up to a root node if one exists, else it becomes the root
it("should create a node under root node", async () => {
const resource = {
node: "ceo"
};
const result = await chai
.request(app)
.post("/api/v1/tree")
.send(resource);
expect(result).to.have.status(status.CREATED);
expect(result).to.be.json;
expect(result.body.data.node).to.eql(resource.node);
expect(result.body.data.parent).to.exist;
expect(result.body.data.parent).to.eql(rootNode);
});
