Complete code is written to fetch data from excel and login to Gmail, but while trying to do so my browser had opened and also the desired page got opened and as well as login id was picked from excel and stored in the variable sUsername, but unable to locate the xpath as- element=driver.findElement(by.id("Email")); but when I print element it holds "null", where as expected was some address of the locator id. Further by using the address of id I would had used with sendkeys to enter the email address in the text box.
But the following error was displayed:
java.lang.NullPointerException
at appModules.SignIN.Execute(SignIN.java:21)
Login class-where the locator issue exists: at - Login1.userName(driver).sendKeys(sUsername);
public class Login1 {
//private static WebDriver driver=null;
private static WebElement element=null;
public static WebElement userName(WebDriver driver)
{
try {
System.out.println("aaa");
System.out.println("bb");
element=driver.findElement(By.name("Email"));
System.out.println("ccc");
} catch (Exception e) {
// TODO: handle exception
System.out.println(element);
}
return element;
}
public static WebElement btn_login(WebDriver driver)
{
element= driver.findElement(By.id("next"));
return element;
}
public static WebElement passWord(WebDriver driver)
{
element= driver.findElement(By.id("Passwd"));
return element;
}
public static WebElement btn_SignIN(WebDriver driver)
{
element= driver.findElement(By.id("signIn"));
return element;
}
}
This is the SigniN class where iam getting the java null pointer exception--issue exists: at- Login1.userName(driver).sendKeys(sUsername);
public class SignIN {
private static WebDriver driver=null;
public static void Execute (int iTestCaseRow)
{
String sUsername=ExcelUtils1.getCellData(iTestCaseRow,Constant1.col_UserName);
System.out.println(sUsername);
//driver.ma3nage().window().maximize();
//driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);
Login1.userName(driver).sendKeys(sUsername);
//driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);
Login1.btn_login(driver).click();
String pass=ExcelUtils1.getCellData(iTestCaseRow, Constant1.col_password1);
Login1.passWord(driver).sendKeys(pass);
Login1.btn_SignIN(driver).click();
}
}
This is where I have instantiate the browser--
public class Utils1 {
public static WebDriver driver;
public static WebDriver OpenBrowser(int iTestCaseRow) {
String sBrowserName;
System.out.println(iTestCaseRow);
sBrowserName = ExcelUtils1.getCellData(iTestCaseRow,
Constant1.col_browser);
if (sBrowserName.equals("Mozilla")) {
driver = new FirefoxDriver();
// Log.info("New driver instantiated");
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
// Log.info("Implicit wait applied on the driver for 10 seconds");
driver.get(Constant1.URL);
// Log.info("Web application launched successfully");
}
return driver;
}
}
It is good practice to deal with internally as well explicit wait for locating element. If there is page related activity then also need to use wait for page to load.
Please follow bellow code
For internal Wait
protected WebElement waitForPresent(final String locator) {
// timeout is your default wait timeout in long.
return waitForPresent(locator, timeout);
}
For Explicit Wait
protected WebElement waitForPresent(final String locator, long timeout) {
WebDriverWait wait = new WebDriverWait(driver, timeout);
WebElement ele = null;
try {
ele = wait.until(ExpectedConditions
.presenceOfElementLocated(locator));
} catch (Exception e) {
throw e;
}
return ele;
}
protected WebElement waitForNotPresent(final String locator, long timeout) {
timeout = timeout * 1000;
long startTime = System.currentTimeMillis();
WebElement ele = null;
while ((System.currentTimeMillis() - startTime) < timeout) {
try {
ele = findElement(locator);
Thread.sleep(1000);
} catch (Exception e) {
break;
}
}
return ele;
}
Just spit balling here, but in addition to the copy/paste issues stated above.. I don't see where you do a 'get' to load the gmail page for the driver instance you are creating? Something like..
driver.get("https://mail.google.com/something");
Also, it would probably be a good idea to put an explicit wait in place for the "Email" field before doing the findElement as the page may still be rendering:
Wait<WebDriver> doFluentWait = fluentWait = new FluentWait<>(driver).withTimeout(PAGE_LOAD_WAIT, TimeUnit.SECONDS)
.pollingEvery(POLLING_INTERVAL, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
and then do something like
doFluentWait.until(WebDriverUtil.elementIsVisible(By.name("Email")));

using Java 17 and slenium 4.0
wait.until(ExpectedConditions.titleContains("BrowserStack"));
here is full code :
public class mainTestClass {
public static final String USERNAME = "myuser *****";
public static final String AUTOMATE_KEY = "my ke *****";
public static final String URL = "https://" + USERNAME + ":" + AUTOMATE_KEY + "#hub-cloud.browserstack.com/wd/hub";

WebElement element = driver.findElement(By.name("q"));
element.sendKeys("BrowserStack");
element.submit();
// Setting the status of test as 'passed' or 'failed' based on the condition; if title of the web page contains 'BrowserStack'
WebDriverWait wait = new WebDriverWait(driver, 5);

System.out.println(driver.getTitle());
driver.quit();

This is cause in Selenium 4.0.0 (Stable)
WebDriverWait which takes driver and timeoutInSeconds long, have been Deprecated
#Deprecated
public WebDriverWait(WebDriver driver, long timeoutInSeconds) {
this(driver, Duration.ofSeconds(timeoutInSeconds));
}
Fix:
Selenium devs have given this method instead
public WebDriverWait(WebDriver driver, Duration timeout) {
this(
driver,
timeout,
Duration.ofMillis(DEFAULT_SLEEP_TIMEOUT),
Clock.systemDefaultZone(),
Sleeper.SYSTEM_SLEEPER);
}
so your effective code will be :
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
try {
wait.until(ExpectedConditions.titleContains("BrowserStack"));
JavascriptExecutor jse = (JavascriptExecutor)driver;
}
catch(Exception e) {
e.printStackTrace();
}
I have this method implemented some time ago. I use it pretty extensively in my web automation.
The gist is to wait for one of several elements to be visible.
public void waitForSomeElementToBeVisible(int timeout, final By... locators) throws Exception, TimeoutException {
boolean found = false;
try {
driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS);
WebDriverWait wait = new WebDriverWait(driver, timeout);
ExpectedCondition<?>[] conditionsToEvaluate = new ExpectedCondition[locators.length];
for (int i = 0; i < locators.length; i++) {
conditionsToEvaluate[i] = ExpectedConditions.visibilityOfElementLocated(locators[i]);
}
found = wait.until(ExpectedConditions.or(conditionsToEvaluate));
} catch (TimeoutException e) {
throw e;
} catch (Exception e) {
throw e;
} finally {
driver.manage().timeouts().implicitlyWait(<default>, TimeUnit.SECONDS);
}
if (!found) throw new Exception("Nothing found");
}
Now I’m trying to use this method with a mobile browser. Specifically, iOS Safari via Appium. It works on iOS occasionally but usually fails and in the Appium log I see when executing the line:
found = wait.until(ExpectedConditions.or(conditionsToEvaluate));
(It does work consistently with Android+Appium).
[WD Proxy] Got response with status 404: {"value":{"error":"no such alert","message":"An attempt was made to operate on a modal dialog when one was not open","traceback":""},"sessionId":"03E95205-9E98-4DB4-BB61-0F125C2C5B3E"}
[debug] [W3C] Matched W3C error code 'no such alert' to NoSuchAlertError
There is, of course, no alert AND one of the elements does exist.
What’s going wrong here?
Is there a better way to wait for one of several elements to be visible?
Please try this java method :
public static boolean waitForElement(WebElement element) throws IOException {
log.info("Waiting for an element in the page...");
boolean isElementPresent = true;
try {
WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.visibilityOf(element));
log.info("Element is visible");
return isElementPresent;
} catch (Exception e) {
log.info("waitForElement method failed! " + e.getMessage());
return !isElementPresent;
}
}
or this method:
public static WebElement fluentWait(final WebElement webElement, int timeinsec) {
log.info("waiting ..."+ timeinsec +" seconds");
FluentWait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout(timeinsec, TimeUnit.SECONDS).pollingEvery(timeinsec, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
WebElement element = wait.until(new Function<WebDriver, WebElement>() {
public WebElement apply(WebDriver driver) {
return webElement;
}
});
return element;
}
FYI: Both of these method are present under the below maven Dependency I created a while ago. It has a lot of re-usable method that you can use :
<dependency>
<groupId>com.github.mbn217</groupId>
<artifactId>MyUtilities</artifactId>
<version>1.0.2</version>
</dependency>
To use it you just need to call the class name and the method. No need to create an object from the class
example:
SeleniumUtils.waitForElement(pass your element here)
I am facing issues with Selenium when navigating from one page to another.
Below is the code. If I click on following element a jQuery image will open until the next page gets loaded. But it's not navigating to next page itself. The image keeps on rotating and window will close that. Why?

I tried all the ways but no luck. Commented lines are my tries but none of them redirects to that page.
I'm trying to type selenium in google and get all the title text of result in a notepad file. i want to get all available links on all the pages, till last page of search. but only 1st page's link i am getting. when i debug and run, it is working for some 10 pages.help me in this.
JAVA code:
public class weblink
{
public static void main(String[] args) throws IOException, InterruptedException {
WebDriver driver;
System.setProperty("webdriver.chrome.driver", "E:\\disha.shah/myWork/eclipse/chromedriver.exe");
driver = new ChromeDriver();

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("http://www.google.co.in/");
driver.findElement(By.id("lst-ib")).sendKeys("Selenium");
driver.findElement(By.id("_fZl")).click();
PrintStream ps = new PrintStream(new File(("E:\\disha1.txt")));
do
{
List<WebElement> findElements = driver.findElements(By.xpath("//*[#id='rso']//h3/a"));
for (WebElement webElement : findElements)
{
System.out.println("-" + webElement.getText()); // for title
//System.out.println(webElement.getAttribute("href")); // for links
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

if(driver.findElement(By.linkText("Next")).isDisplayed()== true)
{
driver.findElement(By.linkText("Next")).click();
}
else
{
System.out.println("All Link is Covered");
}
}
while(driver.findElement(By.linkText("Next")).isDisplayed() );
{
//Thread.sleep(2000);
}
}
}
I've done some correction. the updated code is below.-
public static void main(String[] args) throws IOException, InterruptedException
{
WebDriver driver;
System.setProperty("webdriver.chrome.driver", "D:/Application/chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();

Boolean nextButtonFlag = true;
// Create two separate file storing the result
PrintStream searchTitle = new PrintStream(new File(("D:\\Titles.txt")));
PrintStream searchLink = new PrintStream(new File(("D:\\Links.txt")));
do
{
List<WebElement> findElements = driver.findElements(By.xpath("//h3[#class='r']/a"));
for (WebElement element : findElements)
{
// Write all received links and title inn txt file
searchTitle.append(element.getText()+"\n");
searchLink.append(element.getAttribute("href")+"\n");
}
Thread.sleep(2000);
try
{
driver.findElement(By.linkText("Next")).click();
}
catch(Exception e)
{
// no more next button to navigate further link
nextButtonFlag=false;
}
Thread.sleep(2500);
}
while(nextButtonFlag);
System.out.println("Execution done");
searchTitle.close();
searchLink.close();
}
}
Currently working on Selenium WebDriver, Java and TestNG frame work.
Please give ideas about TestNG framework.
For example, i have a file test.java. I have written java code with
#BeforeTest , #Test, #AfterTest. while running the code each test is running and am getting how many test got passed and how many got failed.
But i want solution for the secnario:
I have two tabs called Default and Internal vs External
After clicking the default tab i want run many test for that particular tab, once those test executed then i need to click on the Internal vs External then i need to run all test belongs to that tab.
How can i get result in the TestNG frame work.

Use the attribute dependsOnMethods, of #Test, to sequentialize your tests. You can read further about the annotations in TestNG at - TectNG Annotations.
So why don't you abstract those tests and than call it in your "Default" and "Internal vs External"? In you case I would use Page Objects
You can use Groups annotation in TestNG. Write all your required Test cases under Default tab, then add that test cases into one group as below
public class Test1 {
#Test(groups = { "functest", "checkintest" })
public void testMethod1() {
}
#Test(groups = {"functest", "checkintest"} )
public void testMethod2() {
}
#Test(groups = { "functest" })
public void testMethod3() {
}
}
And it will execute that particular group test cases, then it will execute another once group test cases are completed.
testng.xml
<test name="Test1">
<groups>
<run>
<include name="functest"/>
</run>
</groups>
<classes>
<class name="example1.Test1"/>
</classes>
</test>
