Hello, we are using aetest to write some integration tests as part of our project. The integration tests spin up an instance of a dev_appserver.py in a *BeforeSuite* function. We use APIs to guarantee that the suite executes before we start the test:
func BeforeSuite() { params := aetest.InstanceParams{StrongConsistency: true} inst := aetest.NewInstance(params) req := aetest.NewRequest("Get", "/", nil) ctx := appengine.NewContext(req) } We have a similar *AfterSuite* that tears down the instance. func AfterSuite() { inst.Close() } Since we want the tests to be completely hermetic, we delete all the entities that we had created during the tests, usually in an *AfterEach* method. func AfterEach() { deleteAllEntitiesFromDatastore("ENTITY_1") deleteAllEntitiesFromDatastore("ENTITY_2") deleteAllEntitiesFromDatastore("ENTITY_3") ... } And, the we have a lot of test cases that simply run against the created instance and use the context acquired through *BeforeSuite*. We have a good mixture of Gets, Puts, Entity Queries, Filter Queries etc. Since a few days, every-time we run our tests, the tests hang at some point during the execution. This point changes as we add and remove some of the tests, but the tests always hang if the number of suites are above a certain threshold. We usually see errors like: <string>: Call error 11: Deadline exceeded (timeout) or like: Expected success, but got an error: <*url.Error | 0xc8210570b0>: { Op: "Post", URL: "http://localhost:59072", Err: {s: "EOF"}, } Post http://localhost:59072: EOF While the tests are hung, if we try to access the datastore through the ip produced in the tests, the request just hangs similar to how it hangs during the tests. This makes us suspicious that there is some kind of a deadlock that is getting introduced during our execution, but we are not able to figure out how to debug it. Also, the test suites have a timeout after which the tests simply crash. At this point, the AfterSuite cannot execute so the test-server remains active in the background, and when we try to access datastore through the admin, we can see all the data that was added as part of the test. For completeness sake, we also use gomocks to abstract out some external services as part of the tests. Any help on debugging this would be very much appreciated.
