Couchbase error during test suite run

[Jordan Wood]

I have a suite of unit tests based on the XCTestCase class, and a section of my tests test our use of Couchbase.  When I run the entire suite, I see a lot of messages in the log which say: 

2016-03-20 08:39:19.031 BrowZine[20654:775436] *** SQLITE database busy: <CBL_FMDatabase: 0x7f8376d3aa40>

Then occasionally, after a bunch of the previous messages, I see this error:

08:39:19.032‖ WARNING: CBL_SQLiteStorage: database is unreadable (err 5)

2016-03-20 08:39:19:031 BrowZine[20654:5e0f] Could not open couchbase DB named 'ios_test_database', error = Error Domain=SQLite Code=5 "database is locked" UserInfo={NSLocalizedDescription=database is locked}

The test fails after this.  If I run the failing tests individually (not all together), the test passes.  I currently know no problems in the normally running app which is triggering this issue, but it doesn't inspire confidence.  What causes these errors, and is there anything I can do in my tests to make them behave more consistently?

Thanks!

Hi Jordan,

Most likely this is a multi-threading issue. Are you using the main thread to run your tasks?

Thanks,
