Я создал новый рамочный проект maven junit5 для тестирования существующих java проектов. Я добавил проект java в путь сборки недавно созданного фреймворка maven junit5. Я щелкнул правой кнопкой мыши по методу, для которого я хотел добавить тестовый пример junit, и выбрал новый тестовый случай junit, изменил исходную папку на новый каталог sven c проекта maven junit5 framework и оставил остальные параметры по умолчанию. Создал тест junit и без проблем запустил его как юнит-тест (скриншот ниже). Выполнение того же теста с использованием maven выдает ошибку ниже. Я добавил плагин surefire в pom (ниже), но все равно получаю ошибку ниже. Использование eclipse.

Обновление: Я очистил пом (ниже), но теперь тесты не обнаружены? когда я запускаю проект с junit, тест обнаружен?

Решение: Использование junit-platform-console-standalone-1.5.2.jar и запуск модулей с помощью команды линия. Похоже, если у нас есть не maven проект, то junit-platform-console-standalone кажется лучшим вариантом.
