What is Mario?

Mario is a java library intended to simplify asynchronous testing with Selenium WebDriver.

It takes care of the activity of polling for certain conditions or states to occur and manages timeouts, replacing the need for explicit or implicit waits.

With Mario you can do:

BrowserDriver browser = new BrowserDriver(new UnsynchronizedProber(1000, 50), new FirefoxDriver());
browser.navigate().to("http://somedomain/url_that_delays_loading");
browser.element(By.id("some-dynamic-element")).hasText("Loaded");
browser.element(By.id("some-button")).click();

instead of:

WebDriver driver = new FirefoxDriver();
driver.get("http://somedomain/url_that_delays_loading");
WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement display = wait.until(ExpectedConditions.presenceOfElementLocated(By.id("some-dynamic-element")));
assertThat("display text", display.getText(), equalTo("Loaded"))
WebElement button = wait.until(ExpectedConditions.elementToBeClickable(By.id("some-button")));
button.click()

Plus you get nice diagnostics messages like:

java.lang.AssertionError:
Tried to:
    check that an element by id "some-button" is enabled
but:
    it was disabled
