[Selenium] common functions comparison

1.Wait for element  in default time or self defined time

When the element need some time to be present , be visible, be not present or be not visible, for example : loading icon, waiting time is very import to get the element.

*

*SeleniumUtil.waitForElementNotVisible(driver, By.cssSelector("div#window-waiting-box"),"Waiting box should disppear in default time which is configured as timeOutInSeconds in environment.xml");

*SeleniumUtil.waitForElementNotVisible(driver, By.cssSelector("div#window-waiting-box"), 120 ,"Waiting box should disappear in 120s");

 

2.Explicit wait

(1)  new WebDriverWait(driver, 10). until(ExpectedConditions.elementToBeClickable(locator));

(2)  new WebDriverWait(driver, 10). until(ExpectedConditions.visibilityOf(locator));

(3)  new WebDriverWait(driver, 10). until(ExpectedConditions.presenceOfElementLocated(locator);

(4)

Function<WebDriver, WebElement> waitFn = new Function<WebDriver, WebElement>() {

@Override

public WebElement apply(WebDriver driver) {

return el.findElement(By.cssSelector("div.rptstatus.rptcomplete"));

}

};

//Detect every 2 seconds,  the maximum time  is 120 seconds

WebDriverWait wait = new WebDriverWait(driver, 120, 2);

wait.withMessage("A processing icon should display in the Status column in the row.”)

wait.until(waitFn);

3.waitForElementVisible    VS  waitForElementPresent

*SeleniumUtil.waitForElementVisible(driver, By.cssSelector("input#btnClose"), "Close button exists but not visible")

*

*SeleniumUtil.waitForElementPresent(driver, By.cssSelector("input#btnClose"), "Close button doesn’t exist")

 

4.waitForElementPresent   VS   waitForAllElementsPresent

*WebElement element = SeleniumUtil.waitForElementPresent(driver, By.cssSelector("input[value='"+buttonName+"']"),"Cannot get button named: "+buttonName);

*

*List<WebElement> elementList = SeleniumUtil.waitForAllElementsPresent(driver, By.cssSelector("div.rtq-grid-row[rowid]"),"Cannot get folders list");

 

5.Some element might be Present/Visible, it also might not. But both conditions are correct.

For example : alert dialog

In this condition, we need to use try{ ...} catch()

 6.Find element under another element

permissionEl.findElement(By.cssSelector("input[value='true']"))

SeleniumUtil.waitForElementVisible(driver, By.cssSelector(".top-bottom-split"), workSpaceEl);

public void catchIfPopUpDialogAndClickClose(){

try{

SeleniumUtil.waitForElementVisible(driver, By.cssSelector("input#btnClose")).click();

logger.info("Dialog pops up");

}

catch(Exception e)

{

logger.info("No dialog pops up");

}

}
