本文整理了Java中org.openqa.selenium.support.ui.Wait.until()方法的一些代码示例，展示了Wait.until()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Wait.until()方法的具体详情如下：
包路径：org.openqa.selenium.support.ui.Wait
类名称：Wait
方法名：until

Wait.until介绍

[英]Implementations should wait until the condition evaluates to a value that is neither null nor false. Because of this contract, the return type must not be Void.

If the condition does not become true within a certain time (as defined by the implementing class), this method will throw a non-specified Throwable. This is so that an implementor may throw whatever is idiomatic for a given test infrastructure (e.g. JUnit4 would throw AssertionError.
[中]实现应该等到条件的计算结果既不是null也不是false。由于本合同，退货类型不得无效。
如果条件在特定时间内（由实现类定义）没有变为true，则此方法将抛出一个未指定的Throwable。这使得实现者可以抛出给定测试基础设施的惯用语句（例如JUnit4会抛出AssertionError）。

@Test(expected = TimeoutException.class)

    assertThat(duration.getSeconds(), is(equalTo(1L)));

  }).withPollingStrategy(AppiumFluentWait.IterationInfo::getInterval)
      .withTimeout(ofSeconds(3))
      .pollingEvery(ofSeconds(1));
  wait.until(FakeElement::isDisplayed);
  Assert.fail("TimeoutException is expected");
}
