Android Toast Accumulation Testing

问题:

Like many others, i've been trying to solve the problem of toast accumulation.

• How to prevent Multiple Toast Overlaps
• toast issue in android
• Cancelling an already open toast in Android
• Best way to avoid Toast accumulation in Android

I finally decided to keep track of the current displayed toast and cancel it when another arrives (there's some more logic involved), but i could have use only one toast and change it message. What i want to know is this... Is there a way to TEST this behaviour? Im currently using Robotium and tried different things, but unfortunately the methods to check for toasts (solo.waitForText and solo.searchForText) aren't helping me as i can't make something like

assertTrue(solo.waitForText(text));
//maybe even some sleep here
assertFalse(solo.searchText(text);

Has anyone done something like this? Is there a way to test this using Robotium? using somethig else?

回答1:

You can use a robotium condition to wait for the text to disappear. Here's a method I use for that.

private void waitForTextToDisappear(final String text, int wait) {
    Condition textNotFound = new Condition() {

        @Override
        public boolean isSatisfied() {
            return !solo.searchText(text);
        }
    };
    assertTrue("Text gone: " + text, solo.waitForCondition(textNotFound, wait));
}
