Google App Engine Datastore - Testing Queries fails

Question

I am currently trying to test a piece of my code that runs a query on the datastore before putting in a new entity to ensure that duplicates are not created. The code I wrot

Answer 1

The way to do this is to force the datastore to be strongly consistent by setting up the context like this:

c, err := aetest.NewContext(&aetest.Options{StronglyConsistentDatastore: true})
    if err != nil {
        t.Fatal(err)
    }

Now the datastore won't need any sleep to work, which is faster, and better practice in general.

Update: This only works with the old aetest package which was imported via appengine/aetest. It does not work with the newer aetest package which is imported with google.golang.org/appengine/aetest. App Engine has changed from using an appengine.Context to using a context.Context, and consequently the way that the test package now works is quite different.
