Using regexp in assertEquals() does not work

Divi's answer for question 2 is fine. For part 1 you can check if an element is displayed like you said:

 webElement.isDisplayed();

Or you could compare the html of the page before and after the event.

driver.getPageSource();

(You could possibly also check the url if that changes after each event).

The one problem with getting the source of the html is that an event might have triggered after your last action and not have completed, leaving the html the same. To get around this you could check some of the following conditions:

(Boolean) ((JavascriptExecutor)driver).executeScript("return jQuery.ready"); 
((JavascriptExecutor)driver).executeScript("return document.readyState").equals("complete");

Or you might be using another javascript framework that has another function similar to jQuery.ready.

Finally you might have an issue with the event only triggering once you have changed the active element, tabbing out of the field etc. So you could run something like:

Actions actionObject = new Actions(driver); 
actionObject.sendKeys(Key.TAB).perform();

Or you could use javascript to set it(I haven't checked the below code and I would set the webElement to the html base element):

((JavascriptExecutor) driver).executeScript("arguments[0].focus();", webElement);

I don't suggest using webdriver to click on the body element as this might undo your last click.

I'm including Divi's answer for Question 2 for completeness:

We can check whether it is redirecting to another page or not by getting the url of the page and comparing it with expected url

WebDriver driver;

driver.getCurrentUrl() // will returns the String value

if your currrent url doesn't matches with your expected url means then you go for two ways

1) You can open your expected url again by using Open function in selenium (or) webdriver navigate method

driver.navigate().to("expected_url");

2) You can use back navigation

driver.navigate().back();

I need to click the link who's href has substring "long" in it. How can I do this?

With the beauty of CSS selectors.

your statement would be...

driver.findElement(By.cssSelector("a[href*='long']")).click();

This means, in english,

Find me any 'a' elements, that have the href attribute, and that attribute contains 'long'

You can find a useful article about formulating your own selectors for automation effectively, as well as a list of all the other equality operators. contains, starts with, etc... You can find that at: http://ddavison.io/css/2014/02/18/effective-css-selectors.html

https://stackoverflow.com/questions/19058637/how-to-click-a-link-whose-href-has-a-certain-substring-in-selenium

You are making a new reference for WebDriver in your Screenshot class. This WebDriver is never instantiated, thus will give you a NullPointerException. Instead you should pass the WebDriver instance as a parameter to the method.

public class Screenshot {

File source;

public void takeScreenshot(WebDriver webDriver) {

    try {
        source = ((TakesScreenshot) webDriver).getScreenshotAs(OutputType.FILE);


    FileUtils.copyFile(source, new File ("/Users/joshuadunn/Desktop/claimsScreenShot.png"));
    System.out.println("Screenshot Taken!!!!");

    } catch (IOException e) {
        e.printStackTrace();
    } 
}

}

And the test case:

@Test
public void testClaimsTestToCalcNode() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("becsStartCalculator")).click();
    driver.findElement(By.id("MARITAL_STATUS_false")).click();
    driver.findElement(By.id("btn_next")).click();
    driver.findElement(By.id("HOME_ABROAD_false")).click();

    *** This is where the null pointer is ***
    *******************************
    screenshot.takeScreenshot(driver);
    *******************************


    driver.findElement(By.id("btn_next")).click();
    driver.findElement(By.id("DETAILS_STUDENT_YOU_false")).click();

Edit: Alternatively you could set the WebDriver in the constructor of Screenshot

public void Screenshot(WebDriver webDriver){
    this.webDriver = webDriver;
}

https://stackoverflow.com/questions/38078918/null-pointer-exception-when-trying-to-take-a-screenshot-with-selenium

if the attribute is not present, it should return null, if it's present and not set then it will return empty string. I think that's the case in your example, if so. Then you should use equal method to compare string rather than == operator.

Below example is about google search box, xxx attribute is not present for search box and so it will return null

    driver = new ChromeDriver();
    driver.get("http://google.com");
    WebElement ele = driver.findElement(By.name("q"));
    String attr = ele.getAttribute("xxx");
    if (attr == null){
        System.out.print("Attribute does not exist");
    }

    else if (attr.equals("")){
        System.out.print("Attribute is empty string");
    }

You can try it out yourself by writing the following html and saving it as test. html:

<html>
    <head>
    </head>
    <body>
        <p id="one">one</p>
        <p id="two" data-se="">two</p>
        <p id="three" data-se="something">three</p>
    </body>
</html>

Then write a web driver script that looks like this:

driver.get("file:///<PATH_TO_HTML_ABOVE>/test.html");

WebElement one = driver.findElement(By.id("one"));
WebElement two = driver.findElement(By.id("two"));
WebElement three = driver.findElement(By.id("three"));

System.out.println("Does one have the data-se attribute?:  '" + one.getAttribute("data-se") + "'");
System.out.println("Does two have the data-se attribute?:  '" + two.getAttribute("data-se") + "'");
System.out.println("Does three have the data-se attribute?:  '" + three.getAttribute("data-se") + "'");

Which will give you the following output:

Does one have the data-se attribute?:  'null' 
Does two have the data-se attribute?:  '' 
Does three have the data-se attribute?:  'something'

https://stackoverflow.com/questions/44847608/how-to-test-if-a-webelement-attribute-exists-using-selenium-webdriver

You can actually do this "semi off the shelf": http://testng.org/doc/documentation-main.html#beanshell

In your particular case, it would be something like this:

<method-selectors>
  <method-selector>
    <script language="beanshell"><![CDATA[
       return groups.containsKey("tsg1.0") && groups.containsKey("smoke");
     ]]></script>
  </method-selector>
</method-selectors>

Just answered a similar question in more detail here: Is it possible to put a condition to TestNG to run the test if that is member of two groups?

https://stackoverflow.com/questions/15919091/testng-groups-can-we-include-two-group-names-and-create-one-group-to-run-tests

    psdbComponent.clickDocumentLink();
    ArrayList<String> tabs2 = new ArrayList<String> (driver.getWindowHandles());
    driver.switchTo().window(tabs2.get(1));
    driver.close();
    driver.switchTo().window(tabs2.get(0));

This code perfectly worked for me. Try it out. You always need to switch your driver to new tab, before you want to do something on new tab.

https://stackoverflow.com/questions/12729265/switch-tabs-using-selenium-webdriver-with-java

It doesn't look like you're actually using the regex. It seems like maybe this is what you're trying to do?

Assert.assertTrue(driver.getTitle().matches("*TST-*[0-9]{5}"));

EDIT #1:

It also seems like your regex might not be quite right, try:

Assert.assertTrue(driver.getTitle().matches(".*TST-\\d{5}.*"));

Top 13 Skills of A Good QA Manager in 2021

I believe that to work as a QA Manager is often considered underrated in terms of work pressure. To utilize numerous employees who have varied expertise from one subject to another, in an optimal way.

Skills for QA manager is one umbrella which should have a mix of technical & non-technical traits. Finding a combination of both is difficult for organizations to find in one individual, and as an individual to accumulate the combination of both, technical + non-technical traits are a challenge in itself.
