Я работаю над проектом Maven TestNG Selenium Java и пытаюсь запустить свои тесты, вызвав свой testng. xml из моего pom. xml. сам проект работает правильно в версии, отличной от maven, но когда я запускаю его через файл pom. xml, он просто запускает все тесты параллельно, открывает веб-сайт и просто запускает все тесты вместе (и мне нужно запускайте их по порядку, потому что они зависят друг от друга, также методы @BeforeSuite и @AfterSuite работают нормально, проблема заключается в выполнении только типа @Test)
Я пытался следовать несколько руководств и подобных примеров проектов на inte rnet, а также удалены и добавлены зависимости в соответствии с ними, но, похоже, ничего из этого не работает.
это мой текущий pom. xml (это беспорядок от этот момент):
