示例1: it
it('correctly invalidates cache and does not fetch', () => {
const resource = new Resource(schema.users);
const store = schema.__node.definition.storeMap.getOrCreate('user');
spy(store, 'invalidate');
return wait_for_promise(() => resource.status === IStatus.complete)
.then(() => {
expect(mock_request_count()).to.equal(1);
resource.invalidate({ foo: 123, noFetchGet: true });
expect(store.invalidate.callCount).to.equal(1);
expect(store.invalidate.getCall(0).args[1]).to.deep.equal({
foo: 123,
noFetchGet: true,
invoker: resource
});
expect(resource.status).to.equal(IStatus.stale);
expect(resource.timestamp).to.equal(ITimestamp.stale);
expect(mock_request_count()).to.equal(1);
})
.then(delay_for())
.then(() => {
// no request occurs after invalidating
expect(mock_request_count()).to.equal(1);
expect(resource.status).to.equal(IStatus.stale);
