У меня есть приложение React с анимацией, использующей React Pose (https://popmotion.io/pose/).
. Это нормально работает, но когда я пишу интеграционный тест для компонента (с использованием реагирующей библиотеки-тестирования), тест завершается неудачно..
Ошибка, которую я получаю при запуске теста:
Error: Uncaught [TypeError: Cannot read property '1' of null]

Похоже, это вызвано регулярным выражением здесь: https://github.com/Popmotion/popmotion/blob/1b181ee1673003cb7239a2696623da3f494217be/packages/popmotion-pose/src/dom/unit-conversion.ts#L28
transform
переменная содержит translateX(-100%) translateZ(0)
, поэтому эта проверка возвращает null
.
Я предполагаю, что у меня проблема из-за того, что что-то не реализовано в jsdom
(аналогично этой проблеме: https://github.com/Popmotion/popmotion/issues/402), но я не уверен, чего не хватает или почему вызывается описанный выше метод (GetActualMeasurementInPixels
), потому что похоже, что он никогда не будет работать.
