在测试期间控制最终的AppEngine数据存储区一致性

Question

I have an AppEngine app written in Go, and I'm trying to improve my tests.

Part of the tests that I need to run are a series of create, update, delete queries on the same object. However given that the datastore is eventually consistent (these aren't child objects), I am currently stuck using a time.Sleep(time.Second * 5) to give the simulated datastore in the SDK enough time for consistency to propagate.

This results in tests that take a long time to run. How can I force something more like strong consistency for tests without rewriting my code to use ancestor queries?

Answer 1

It's been a while, but the method that I found that works well is to call the context as follows:

c, err := aetest.NewContext(&aetest.Options{StronglyConsistentDatastore: true})
