java .lang.AssertionError: Нет значения в JSON путь "[0] .id"

0 голосов
/ 06 марта 2020

Я пытаюсь исправить testGetAllUsers(), но он продолжает возвращаться java.lang.AssertionError: No value at JSON path "[0].id". По сути, это база данных в памяти, которая должна воссоздавать себя при каждом запуске.

Вторая проблема заключается в том, что поле role всегда равно нулю, даже если оно установлено на moderator. Может быть, это потому, что я добавил это позже? Как мне это исправить? Удаление test-db файлов не работает.
