У меня проблема, что PITest пропускает некоторые из моих тестов. Он сообщает об отсутствии покрытия строки для тестируемого класса и обо всех мутациях в оставшихся в живых:
заменено возвращаемое значение на Collections.emptyList для ... → NO_COVERAGE
Список ниже пуст:
Тесты изучены
Я проверил следующее:
- файл класса класса и теста поддерживается в одном из каталогов в пути к классам
- тест не исключен
- тесты в том же каталоге запускаются
- исходный каталог указан правильно
- на консоли не возникает ошибок, даже при ведении журнала с verbose=true
- Я зарегистрировался и проверил все параметры
<pitest
pitClasspath="pit.path"

Я использую PITest версии 1.4.11, но также тестировал версии 1.6.2 и 1.4.3. Также я использую Java 1.8.0_211 и ant 1.9.13.
Я создал тестовый проект по адресу: https://github.com/johannesn/pittestskippingtests.
