Я создал тестовый класс JUnit и провел его с Gradle, и жизнь была хорошей.
Я создал другой тестовый класс JUnit в другом пакете, выполнил ту же команду Gradle, и теперь жизнь стала хуже.Хуже всего то, что время от времени это только хуже.
Иногда все работает:
$ gradle clean cleanTest test
> Task :product:java:common:test
package1.DataSourceDetailsUtilsTest > onlyOverrides() PASSED
package1.DataSourceDetailsUtilsTest > onlyDefaults() PASSED
package1.DataSourceDetailsUtilsTest > onlyTenant() PASSED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test1() PASSED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test2() PASSED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test3() PASSED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test4() PASSED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test5() PASSED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test6() PASSED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test7() PASSED
BUILD SUCCESSFUL in 3s
21 actionable tasks: 5 executed, 16 up-to-date
Даже в этом случае обратите внимание, что левая сторона всегда package1.DataSourceDetailsUtilsTest, хотя это только 1 изтестовые классы.
Иногда тесты не выполняются:
> Task :product:java:common:test FAILED
package1.DataSourceDetailsUtilsTest > onlyOverrides() PASSED
package1.DataSourceDetailsUtilsTest > onlyDefaults() PASSED
package1.DataSourceDetailsUtilsTest > onlyTenant() PASSED
package2.UUIDServiceTests > initializationError FAILED
java.lang.AssertionError
4 tests completed, 1 failed
FAILURE: Build failed with an exception.
Обратите внимание, как левая часть правильно переходит от package1.DataSourceDetailsUtilsTest к package2.UUIDServiceTests.Это то, что я ожидал.Ошибка AssertionError вставляется внизу этого поста.
Иногда тесты не выполняются по-разному:
> Task :product:java:common:test FAILED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test1() PASSED
package1.DataSourceDetailsUtilsTest > onlyTenant() PASSED
package1.DataSourceDetailsUtilsTest > onlyOverrides() PASSED
package1.DataSourceDetailsUtilsTest > onlyDefaults() PASSED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test2() SKIPPED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test3() SKIPPED
package1.DataSourceDetailsUtilsTest > package2.UUIDServiceTests.test4() SKIPPED

package2.UUIDServiceTests > initializationError FAILED
java.lang.AssertionError
Caused by: java.lang.AssertionError
8 tests completed, 1 failed, 3 skipped
Опять же, обратите внимание, что левая сторона равна package1.DataSourceDetailsUtilsTest, даже если тест из package2.UUIDServiceTests запускается первым.
Это не редкое явление.Около 40% времени, которое они проходят, около 40% времени, когда они терпят неудачу первым способом, и около 20% времени, когда они терпят неудачу вторым способом
Тестовые классы очень просты.Только пустые методы с аннотацией @Test.Никаких настроек или сносов.Чтобы убедиться, что я ничего не делаю, я буквально перевел каждый тест на 1 секунду: Thread.sleep(1000); и все еще могу воспроизвести проблему.Кажется, он всегда работает, когда есть только один тестовый класс (то есть, если я закомментирую один из классов)
После еще одного исследования у меня будет junit.jupiter.execution.parallel.enabled=true, и если я изменю его на false,затем все снова работает, поэтому я полагаю, что Gradle выполняет задание на параллелизм.
Это не поддерживается?
