Gradle connectedAndroidTest терпит неудачу с " не найдено тестов."но результаты теста выходов

недавно мы начали добавлять тесты в наш проект Android app. Мы начали использовать Robolectric, но недавно пришлось вытащить это и просто использовать простые тесты вместо этого из-за проблемы, с которой мы столкнулись с Couchbase. Перед добавлением Couchbase наши тесты отлично работали при работе с Roblectric.

из новой ветви, в которой нет Couchbase, я вытаскиваю Robolectric и переключаюсь на использование стандартных подключенных тестов. Я вытащил Robolectric, и все наши тесты снова работают. Тестовый отчет HTML генерирует правильно со всеми результатами, которые мы ожидаем. Если тест не удался, консоль точно отражает, какой тест не удался и почему.

проблема, с которой мы сталкиваемся, заключается в том, что, хотя все тесты снова работают (и проходят), тестирование завершается со следующим сообщением:

com.android.builder.testing.ConnectedDevice > hasTests[Nexus 4 - 4.4.4] FAILED 
No tests found.
:libraries:Android-ZXing-Lib:connectedAndroidTest FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':libraries:Android-ZXing-Lib:connectedAndroidTest'.
> There were failing tests. See the report at: file:///Users/MyAccount/Git%20Repos/MyProject/libraries/Android-ZXing-Lib/build/outputs/reports/androidTests/connected/index.html

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

работает с --stacktrace Я вижу, что это определенно исходит из этой библиотеки.

есть ли способ для меня нет conectedAndroidTest работать на библиотеках, которые мы не поддерживаем?
