I'm trying to use eval function to create a driver object in selenium. But am getting an error - "ReferenceError: "FirefoxDriver" is not defined". At line - "Object objBrow = objJSEngine.eval(strTxt);"
As I want to put the string -driver type in property file eventually. Below is the code.
Could anyone help me on this. Thanks.

//Create Driver object
ScriptEngineManager objManager = new ScriptEngineManager();
ScriptEngine objJSEngine = objManager.getEngineByName("js");
strTxt = "new"+"\t "+strBorwserType+"();" ;
Object objBrow = objJSEngine.eval(strTxt);
WebDriver objBrowser = (WebDriver)objBrow;
//Launch the application
objBrowser.get(strURL);
objBrowser.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
System.out.println("Application launched");
objBrowser.manage().window().maximize();
//Click Twitter Link
objBYTwiter = By.cssSelector(strClassName);
objTwitterTag = objBrowser.findElement(objBYTwiter);
objTwitterTag.click();
}
}
What you are asking is not possible.
You can create a method something like:
WebDriver selenium;
public void setSelenium(String driver) {
if (driver.equals("firefox")) {
selenium = new FirefoxDriver();
} else if (driver.equals("chrome")) {
System.setProperty("webdriver.chrome.driver", "path to chrome");
selenium = new ChromeDriver();
} // define more as you need
}
Then you can call this method with something like:
setSelenium(System.getenv("browser"));
Where in your environment you first set the variable "browser" to whichever you want to run. You can also get this value from something else, like a file.

I had tried to create method and call it from another file to the main class but It won't work the error message said "java.lang.NullPointerException"
Main.class
Keywords kw = new Keywords();
#When("^gmailDD$")
public void gmailDD() throws Throwable{
WebDriverWait wait5s = new WebDriverWait(driver, 5);
String regis = "/html/body/div[2]/div[1]/div[5]/ul[1]/li[3]/a";
String dd = "/html/body/div[1]/div/footer/div/div/div[1]";
String empty = "/html/body/div[1]/div/footer";
kw.clickbyxpath(regis);
String handle= driver.getWindowHandle();
System.out.println(handle);
// Store and Print the name of all the windows open
Set handles = driver.getWindowHandles();
System.out.println("Log window id: "+handles);
driver.switchTo().window("6442450949");
kw.clickbyxpath(empty);
kw.clickbyxpath(dd);
}`
Method.class
WebDriver saddriver;
public void clickbyxpath (String xpathvalue) throws InterruptedException, IOException
{
WebDriverWait sad = new WebDriverWait(saddriver, 10);
//To wait for element visible
System.out.println(xpathvalue);
String x = xpathvalue;
sad.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(x)));
wowdriver.findElement(By.xpath(x)).click();
}
I had tried to do the same coding in the same file, It has no problem but when I move Method.class to the new file, error message said "java.lang.NullPointerException" but I can get "xpathvalue" value.
This Error occur because of it will not able to find your driver instance.
refer below code snippet. this is not cucumber example but you can get idea by this.
Method.class
package testing.framework;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class Method {
public WebDriver driver;
WebElement _clickForSearch;
public Method(WebDriver driver) {
this.driver = driver;
}
public Method clickByXpath(String xpathValues) {
WebDriverWait wait = new WebDriverWait(driver, 10);
_clickForSearch = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(xpathValues)));
_clickForSearch.click();
return this;
}
}
Testing.class
package testing.framework;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Testing {
public static WebDriver driver;
public static void main(String[] args) {
getWebDriver();
String xpathValues= "//div[#class='FPdoLc VlcLAe']//input[#name='btnK']";
Method m1 = new Method(driver);
m1.clickByXpath(xpathValues);
}
public static void getWebDriver() {
System.setProperty("webdriver.chrome.driver", "Your chrome driver path");
driver = new ChromeDriver();
driver.get("https://www.google.com");
}
}
You need to pass your driver instance to another.
So I would suggest you take the webdriver wait out of your method and instantiate it when instantiating your webdriver. I would then create methods like so:
Driver class
private final String USER_DIRECTORY = System.getProperty("user.dir");
private final int GLOBAL_TIMEOUT = 30;
private WebDriver webDriver;
private WebDriverWait webDriverWait;
public Driver(String browserName) {
this.browserName = browserName;
System.out.println(browserName);
switch (this.browserName.toUpperCase()) {
case "CHROME":
initializeChromeDriver();
break;
}
}
private void initializeChromeDriver() {
System.setProperty("webdriver.chrome.driver", USER_DIRECTORY.concat("\\drivers\\chromedriver.exe"));
webDriver = new ChromeDriver();
webDriver.manage().window().maximize();
webDriverWait = new WebDriverWait(webDriver, GLOBAL_TIMEOUT);
}
Click method
public void buttonClickByXpath(String xpath) {
try {
WaitForPreseneOfElement(xpath);
webDriver.findElement(By.xpath(xpath)).click();
} catch (Exception e) {
takeScreenshot();
AllureLog("Failed to click on the button object. Please check your xpath. | xpath used = " + xpath + "");
Assert.fail();
}
}
Test Class
Import your driver class
import Base.Driver;
Then you would need declair your driver class like so:
Driver driver;
Now you will have access to your method using
driver.buttonClickByXpath(//YourXpathHere)
The problem is "Method m1 = new Method(driver);" keyword,
I had coded this line outside the main method.
thank you very much, Sir
I am trying to get data from a webpage (http://steamcommunity.com/id/Winning117/games/?tab=all) using a specific tag but I keep getting null. My desired result is to get the "hours played" for a specific game - Cluckles' Adventure in this case.
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
public class TestScrape {
public static void main(String[] args) throws Exception {
String url = "http://steamcommunity.com/id/Winning117/games/?tab=all";
Document document = Jsoup.connect(url).get();
Element playTime = document.select("div#game_605250").first();
System.out.println(playTime);
}
}
Edit: How can I tell if a webpage is using JavaScript and is therefore unable to be parsed by Jsoup?
To execute javascript in java code there is Selenium :
Selenium-WebDriver makes direct calls to the browser using each
browser’s native support for automation.
To include it with maven use this dependency:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-server</artifactId>
<version>3.4.0</version>
</dependency>
Next I give you code of simple JUnit test that creates instance of WebDriver and goes to given url and executes simple script to get rgGames .
File chromedriver you have to download at https://sites.google.com/a/chromium.org/chromedriver/downloads.
package SeleniumProject.selenium;

#RunWith(JUnit4.class)
public class ChromeTest extends TestCase {

public static void createAndStartService() {

try {

} catch (IOException e) {
System.out.println("service didn't start");
// TODO Auto-generated catch block

}
}
#AfterClass
public static void createAndStopService() {
service.stop();
}
#Before
public void createDriver() {
ChromeOptions chromeOptions = new ChromeOptions();
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
driver = new RemoteWebDriver(service.getUrl(), capabilities);
}
#After
public void quitDriver() {
driver.quit();
}
#Test
public void testJS() {
JavascriptExecutor js = (JavascriptExecutor) driver;
// Load a new web page in the current browser window.
driver.get("http://steamcommunity.com/id/Winning117/games/?tab=all");
// Executes JavaScript in the context of the currently selected frame or
// window.
ArrayList<Map> list = (ArrayList<Map>) js.executeScript("return rgGames;");
// Map represent properties for one game
for (Map map : list) {
for (Object key : map.keySet()) {
// take each key to find key "name" and compare its vale to
// Cluckles' Adventure
if (key instanceof String && key.equals("name") && map.get(key).equals("Cluckles' Adventure")) {
// print all properties for game Cluckles' Adventure
map.forEach((key1, value) -> {
System.out.println(key1 + " : " + value);
});
}
}
}
}
}
As you can see selenium loads page at
driver.get("http://steamcommunity.com/id/Winning117/games/?tab=all");
And to get data of all games by Winning117 it returns rgGames variable:
ArrayList<Map> list = (ArrayList<Map>) js.executeScript("return rgGames;");
The page you want to scrape is load by js,and there is not any #game_605250 element that jsoup get.All datas are write in page by using js.
But when I print document to a file ,I see some data like this:
<script language="javascript">
var rgGames = [{"appid":224260,"name":"No More Room in Hell","logo":"http:\/\/cdn.steamstatic.com.8686c.com\/steamcommunity\/public\/images\/apps\/224260\/670e9aba35dc53a6eb2bc686d302d357a4939489.jpg","friendlyURL":224260,"availStatLinks":{"achievements":true,"global_achievements":true,"stats":false,"leaderboards":false,"global_leaderboards":false},"hours_forever":"515","last_played":1492042097},{"appid":241540,"name":"State of Decay","logo":"http:\/\/....
then,you can extract 'rgGames' by some StringTools and format it to json obj.
It't not a clerver method,but it worked
try this :
public class TestScrape {
public static void main(String[] args) throws Exception {
String url = "http://steamcommunity.com/id/Winning117/games/?tab=all";
Document document = Jsoup.connect(url).get();
Element playTime = document.select("div#game_605250");
Elements val = playTime.select(".hours_played");
System.out.println(val.text());
}
}
I'm using flex-ui-selenium to automate my flex application, which adds 2 numbers and displays the result in an alert box.
Below is my selenium code:

WebDriver driver = new ChromeDriver();
//FlashObjectWebDriver driver1 = new FlashObjectWebDriver((FlashObjectWebDriver) driver,"SeleniumTest");
driver.get(BASE_URL);
driver.manage().window().maximize();
FlexUISelenium flexUITester;
flexUITester = new FlexUISelenium((Selenium) driver, "SeleniumTest");
flexUITester.type("100").at("first");
flexUITester.type("200").at("second");
flexUITester.click("Sum");
}

When I execute this code, I get the following exception:

Please help.
I am very new at working with Selenium. I am trying to click on the following Select button:
Here is my code:
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
public class FirstTest
{
private static WebDriver driver;
public static void main(String[] args) throws Exception
{
driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.navigate().to("http://www.metro.ca/flyer/index.en.html");
WebElement postalCodeInputBox = driver.findElement(By.name("postalcode"));
postalCodeInputBox.sendKeys("L6R1A1");
postalCodeInputBox.submit();
String pageSource = driver.getPageSource();
if(pageSource.contains("setstore btn"))
System.out.println("setstore btn FOUND");
WebElement selectButton = driver.findElement(By.className("setstore btn"));
selectButton.click();
}
}
Picture confirming that "setstore btn" is in the source:
Here is "setstore btn" in the source:
It's very likely caused by you trying to search for two separate classes in the single By.className(). "setstore" and "btn" are each their own classes.
Try replacing
WebElement selectButton = driver.findElement(By.className("setstore btn"));
with
WebElement selectButton = driver.findElement(new ByAll(By.className("setstore"), By.className("btn")));
Alternatively, https://stackoverflow.com/a/16090160/1055102 provides another good option.
WebElement selectButton = driver.findElement(By.cssSelector(".setstore.btn"));
I am trying to copy the table data of the html page which is loaded on the same page after clicking on the 'Get Table' button on the previous page. However, as the page url is not changing I am getting exception of 'No such element' when trying to locate new elements on newly loaded page. Following is the code I tried:
package com.test.selenium;
import java.util.List;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.Select;
import org.openqa.selenium.support.ui.WebDriverWait;
import junit.framework.Test;
import junit.framework.TestSuite;
public class Example1{
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "D:\\Java Stuff\\Selenium Tutorial\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://www.oanda.com/currency/table");
WebElement date = driver.findElement(By.name("date"));
date.sendKeys("12/04/10");
WebElement date_frmt = driver.findElement(By.name("date_fmt"));
date_frmt.sendKeys("yy/mm/dd");
WebElement curr = driver.findElement(By.name("exch"));
curr.sendKeys("US Dollar.USD");
Select sel = new Select(driver.findElement(By.name("Currency")));
sel.deselectAll();
List lsize = sel.getOptions();
int count = lsize.size();
for(int j=0;j<count;j++)
{
String lvalue = sel.getOptions().get(j).getText();
sel.selectByVisibleText(lvalue);
}
WebElement crr = driver.findElement(By.name("dest"));
crr.click();
driver.getCurrentUrl();
String table = driver.findElement(By.id("converter_table")).getText();
System.out.println(table);
}
}
According to exception it seems that element not exists on the page, or smth wrong with you xpath. Why you use xpath?! Try css selectors (they are more powerful and stable) =) e.g.
driver.findElement(By.css("#converter_table"));
P.S. if you want to verify that your selector is correct (no matter xpath or css) use dev console in browser (e.g. for css enter $("#converter_table") in console, and if element exists (and this id has no type in the name) then you'll see what this selector will return)). For xpath use $x("xpath")
UPDATE:
Simple solution i think is to add some method which will wait for element, some period of time. Below sample code in C# (test with wait method)
private IWebDriver driver;
[SetUp]
public void SetUp()
{
// Here i just create browser as you (firefox, chrome etc);
driver = CreateBrowser("http://www.oanda.com/currency/table");
}
[TearDown]
public void TearDown()
{
driver.Dispose();
}
[Test]
public void PortTest()
{
var dateElement = driver.FindElement(By.Name("date"));
dateElement.SendKeys("12/04/10");
var dateFrmt = driver.FindElement(By.Name("date_fmt"));
dateFrmt.SendKeys("yy/mm/dd");
var curr = driver.FindElement(By.Name("exch"));
curr.SendKeys("US Dollar.USD");
var crr = driver.FindElement(By.Name("dest"));
crr.Click();
WaitUntilLoad();
var table = driver.FindElement(By.Id("converter_table"));
Console.Write("the text is " + table.Text);
}
public void WaitUntilLoad()
{
int repetitionCount = 0;
bool isLoaded = false;
while (!isLoaded)
{
var table = driver.FindElements(By.Id("converter_table")).Count;
if (table > 0 )
isLoaded = true;
Thread.Sleep(250);
repetitionCount++;
Console.WriteLine("Searching again for element");
if (repetitionCount > 25) break;
}
}
you get NoSuchElement because your xpath seems wrong
try
WebElement myDynamicElement = (new WebDriverWait(driver, 10))
.until(ExpectedConditions.presenceOfElementLocated(By.xpath(".//*[#id='content_section']/table")));
String table = driver.findElement(By.xpath(".//*[#id='content_section']/table")).getText();
