javafx-2 - 在 TestFX 版本 4 中，我如何才能等到 GUI 的元素变得可见？

Question

我Matcher应该使用什么？ 似乎不再可用，不幸的是我在图书馆visible()找不到替代品。org.hamcrest

提前致谢！

Answer 1

You may use Awaitility utility.

This is an example of a utility method where it waits by default up to 10 seconds starting after 10 milliseconds:

public <T extends Node> T lookupById(final String controlId) {
    Awaitility
            .await()
            .pollDelay(10, TimeUnit.MILLISECONDS)
            .until(() -> robot.lookup(controlId).query() != null);

    return robot.lookup(controlId).query();
}

You may implement any condition of waiting, for example, checking of additional visibility property, etc.

The result of negative scenario:

org.awaitility.core.ConditionTimeoutException: Condition with lambda expression in com.MyClass was not fulfilled within 10 seconds.
