Examples with Duration org.openqa.selenium.support.ui.Duration used on opensource projects

Example 1 with Duration

use of org.openqa.selenium.support.ui.Duration in project java-client by appium.

the class AppiumFluentWaitTest method testIntervalCalculationForCustomStrategy.

@Test
public void testIntervalCalculationForCustomStrategy() {
    final FakeElement el = new FakeElement();
    final AtomicInteger callsCounter = new AtomicInteger(0);
    // Linear dependency
    final Function<Long, Long> pollingStrategy = x -> x * 2;
    final Wait<FakeElement> wait = new AppiumFluentWait<>(el, new SystemClock(), duration -> {
        int callNumber = callsCounter.incrementAndGet();
        assertThat(duration.in(TimeUnit.SECONDS), is(equalTo(pollingStrategy.apply((long) callNumber))));
        Thread.sleep(duration.in(TimeUnit.MILLISECONDS));
    }).withPollingStrategy(info -> new Duration(pollingStrategy.apply(info.getNumber()), TimeUnit.SECONDS)).withTimeout(4, TimeUnit.SECONDS).pollingEvery(1, TimeUnit.SECONDS);
    try {
        wait.until(FakeElement::isDisplayed);
        Assert.fail("TimeoutException is expected");
    } catch (TimeoutException e) {
        // this is expected
        assertThat(callsCounter.get(), is(equalTo(2)));
    }
}

Example 2 with Duration

use of org.openqa.selenium.support.ui.Duration in project java-client by appium.

the class AppiumFluentWaitTest method testCustomStrategyOverridesDefaultInterval.

@Test
public void testCustomStrategyOverridesDefaultInterval() {
    final FakeElement el = new FakeElement();
    final AtomicInteger callsCounter = new AtomicInteger(0);
    final Wait<FakeElement> wait = new AppiumFluentWait<>(el, new SystemClock(), duration -> {
        callsCounter.incrementAndGet();
        assertThat(duration.in(TimeUnit.SECONDS), is(equalTo(2L)));
        Thread.sleep(duration.in(TimeUnit.MILLISECONDS));
    }).withPollingStrategy(info -> new Duration(2, TimeUnit.SECONDS)).withTimeout(3, TimeUnit.SECONDS).pollingEvery(1, TimeUnit.SECONDS);
    try {
        wait.until(FakeElement::isDisplayed);
        Assert.fail("TimeoutException is expected");
    } catch (TimeoutException e) {
        // this is expected
        assertThat(callsCounter.get(), is(equalTo(2)));
    }
}

Example 3 with Duration

use of org.openqa.selenium.support.ui.Duration in project java-client by appium.

the class AppiumFluentWait method until.

/**
 * Repeatedly applies this instance's input value to the given function until one of the following
 * occurs:
 * <ol>
 * <li>the function returns neither null nor false,</li>
 * <li>the function throws an unignored exception,</li>
 * <li>the timeout expires,</li>
 * <li>the current thread is interrupted</li>
 * </ol>.
 *
 * @param isTrue the parameter to pass to the expected condition
 * @param <V>    The function's expected return type.
 * @return The functions' return value if the function returned something different
 *         from null or false before the timeout expired.
 * @throws TimeoutException If the timeout expires.
