Executing Selenium tests one after the other without re launching the browser through testng

I have two testcases that has to be executed
1.Login to an App
2.Perform some operations
Below is the design of my code:
BaseTest.java
public abstract class BaseTest {
public WebDriver driver;
#BeforeSuite
public void openApplication() {
System.setProperty(chrome_key,chrome_value);
ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-notifications");
driver = new ChromeDriver(options);
driver.manage().window().maximize();
driver.get(url);
}
}
LoginPage.java
public class LoginPage extends BasePage{
#FindBy (xpath = "//input[#id='username']")
WebElement userName;
#FindBy (xpath = "//input[#id='password']")
WebElement password;
public LoginPage(WebDriver driver) {
super(driver);
PageFactory.initElements(driver, this);
}
public void loginToApp(String username, String pwd) {
}
}
Account.java:
public class NewAccount extends BasePage{
#FindBy(xpath = "//span[text()='Accounts']/../..")
WebElement accountsTab;
public NewAccount(WebDriver driver) {
super(driver);
PageFactory.initElements(driver, this);
}
public void createNewAccount() {
}
}
LoginToApp.java:
public class LoginToApp extends BaseTest {
#Test
public void a_verifyLogin() throws IOException {
LoginPage hp = new LoginPage(driver);
hp.loginToApp(username, password);
}
}
CreateAccount.java:
public class CreateAccount extends BaseTest {
#Test
public void b_createAccountRecord() {
NewAccount na = new NewAccount(driver);
na.createNewAccount();
}
}
testng.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<suite name="Suite">
<test name="Test">
<classes>
<class name="com.testcases.LoginToApp"/>
<class name="com.testcases.CreateAccount"/>
</classes>
</test> <!-- Test -->
</suite> <!-- Suite -->
With this framework structure, When I execute the testng.xml file, the first test in LoginToApp executes as expected. And When the control comes to the test in CreateAccount, the driver becomes Null and hence failing the execution of the 2nd Test.
Expected Flow:
1.Initialise Browser
2.Launch the url
3.Execute the #Test method of LoginToApp.java
4.Execute the #Test method of CreateAccount.java
Is it possible to achieve the above flow without making the WebDriver as static? If yes, please explain.

1.Initialise Browser (set this under before method)
2.Launch the url (give priority =0)
3.Execute the #Test method of LoginToApp.java (give priority =1)
4.Execute the #Test method of CreateAccount.java( give depends on method )
depends on method only execute if your loginapp test successfully run

Java + Selenium Session ID is null. Using WebDriver after calling quit()

I am having issues trying to run Selenium Web driver in a specific way, I've have setup TestNG + Selenium Web driver in my framework, the thing that I would like to accomplish is to run two suites that I've set up in the TestNG.xml files as bellow:
TestNG.xml
<suite>
<suite-files>
<suite-file path="src/testNG/suites/UserSignsOn.xml" />
<suite-file path="src/testNG/suites/PreSetup.xml" />
</suite-files>
</suite>
PreSetup.xml
<suite name="Pre Setup">
<test name="pre setup suite">
<classes>
<class name="Tests.PreSetup" />
</classes>
</test>
</suite>
UserSignsOn.xml
<suite name="User Signs On">
<test name="Get the Web Application">
<classes>
<class name="Tests.LoginPageTest" />
</classes>
</test>
</suite>
My test files look like this:
LoginPageTest.class
public class LoginPageTest extends BaseTest {
#Test
#Description("Login to the web application")
public void signInTheWebApplicationLocalHost(){ // some steps here }
}
PreSetup.class
public class PreSetup extends BaseTest {
#Test
#Description("Pre setup")
public void preSetupSteps(){ // some steps here }
}
As you can see my Test files extends a class, which is the following:
BaseTest.class
public class BaseTest {
protected EnvironmentManager environmentManager;
#BeforeTest
public void testSetup() {
environmentManager = EnvironmentManager.getInstance();
if(environmentManager.getDriver() == null){
// Here I am set up the driver!!!
environmentManager.initWebdriver();
environmentManager.startWebApplication();
}
}
#BeforeMethod
public void testName(ITestResult result){ // perform some actions }
#AfterMethod
public void status(ITestResult result){ // perform some actions }
#AfterTest // Here I am shutting down the driver
public void tearDown() { environmentManager.shutdownDriver(); }
}
The BaseTest.class calls to the EnvironmentManager.class which is a singleton class
It has the bellow code:
public class EnvironmentManager {
private static EnvironmentManager instance = null;
private WebDriver driver = null;
private String url = "www.google.com";
private EnvironmentManager(){}
// Public Methods
public void initWebdriver() {
if(driver == null){ driver = new ChromeDriver(); }
}
public void startWebApplication(){ driver.get(url); }
// Singleton method
public static EnvironmentManager getInstance() {
if (instance == null) instance = new EnvironmentManager();
return instance;
}
public void shutdownDriver(){
driver.quit();
driver = null;
}
public WebDriver getDriver(){ return driver; }
}
The issue resides after running the second test "PreSetup", in the console I got the error:
Session ID is null. Using WebDriver after calling quit()?
I notice that in the first test the driver session is:
ChromeDriver: chrome on MAC (0ff799fbfd14fc275b3b45c414765b15)
And in the second test is a different one:
ChromeDriver: chrome on MAC (09c6c47344756fe2979ee8a84094b1e3)
Any help is welcome :)

for all interested the solution is to rename the following testNG annotations:
#BeforeTest
#AfterTest
to
#BeforeSuite
#AfterSuite

TestNG Parameterisation: NullPointerException when passing browser type to Base class

I have a Base class with a method to open my URL that is called as #BeforeMethod in my test cases. The method takes a string argument for browser type which determines which browser is called. I am attempting to set a parameter in my xml launch file that can be inputted in my #BeforeMethod as argument for the openURL method.
Here is my XML file:
<?xml version="1.0" encoding="UTF-8"?>
<suite name="FullRegressionSuite" parallel="false">
<listeners>
<listener class-name="reporting.CustomReporter"></listener>
</listeners>
<test name="Test">
<parameter name ="browserType" value="Chrome"/>
<classes>
<class name="reporting.reporterTest"/>
</classes>
</test> <!-- Test -->
</suite> <!-- Suite -->
Here are my tests:
#Listeners(CustomListener.class)
public class reporterTest extends Base {
#Test
public void testOne() {
Assert.assertTrue(true);
}
#Test
public void testTwo() {
Assert.assertTrue(false);
}
#Parameters({ "browserType" })
#BeforeMethod
public void setUp(String browserType) throws InterruptedException {
System.out.println(browserType);
openURL(browserType);
}
#AfterMethod
public void tearDown() {
driver.quit();
}
}
Here is my base class:
public class Base {
public static WebDriver driver = null;
//CALL WEB BROWSER AND OPEN WEBSITE
public static void openURL(String browser) throws InterruptedException {
//launches browser based on argument given
try{
if (browser == "Chrome") {
System.setProperty("webdriver.chrome.driver", "/Users/rossdonohoe/Desktop/SeleniumJava/Drivers/chromedriver");
driver = new ChromeDriver();
}
else if (browser == "Firefox") {
System.setProperty("webdriver.gecko.driver", "/Users/rossdonohoe/Desktop/SeleniumJava/Drivers/geckodriver");
driver = new FirefoxDriver();
}
else {
System.out.println("Error: browser request not recognized");
}
driver.manage().deleteAllCookies();
driver.manage().window().maximize();
driver.get("https://www.google.com");
}
catch(Exception E) {
E.printStackTrace();
}
}
}
My #BeforeMethod is definitely receiving the parameter, as I'm printing its value to check and I'm getting "Chrome" in the console. However, openURL is failing at the 'delete all cookies' line with a null pointer exception (and my line "Error: browser request not recognized' is being printed in console), indicating that the string is not reaching openURL as an argument. Can anyone see what I'm doing wrong?

As the browser is a String variable , you need to use equals or contains or equalsIgnoreCase to check if the browser that you are fetching is "Chrome" or "Firefox".
So you need to use: if(browser.equals("Chrome")) and if(browser.equals("Firefox")) as the conditions instead of the conditions that you have used.

FAILED CONFIGURATION: Method beforeTest requires 1 parameters but 0 were supplied in the #Configuration annotation

I was trying to create a function for Browserloading, and called it from another class , but getting below error.
FAILED CONFIGURATION: #BeforeMethod beforeTest
org.testng.TestNGException:
Method beforeTest requires 1 parameters but 0 were supplied in the #Configuration annotation.
I also created testNG parameter in testNG xml file
Below is my function I created for Browser loading so that i can call it from another classes
import com.seleniumdata.zmartano.LoanDetails;
public class Browser {
public static WebDriver driver;
LoanDetails objLoan = new LoanDetails();
#BeforeMethod
#Parameters("Browser")
public void beforeTestUtility(String browser) throws Exception {
LoanDetails.beforeTest(browser);
}
#Test
public static void GetBrowser(String Browser)
{
if (Browser.equalsIgnoreCase("Firefox")) {
Log.info("Driver Initiated");
System.setProperty("webdriver.firefox.driver", Constants.geckodriver);
driver = new FirefoxDriver();
driver.get(Constants.URL);
Log.info("Application Opening");
driver.manage().window().maximize();
}
else if (Browser.equalsIgnoreCase("Chrome")) {
Log.info("Driver Initiated");
System.setProperty("webdriver.chrome.driver", Constants.chromedriver);
driver = new ChromeDriver();
driver.get(Constants.URL);
Log.info("Application Opening");
driver.manage().window().maximize();
}
}
}
My another class from where i need to call the browser function
public class LoanDetails {
public static WebDriver driver ;
public static void beforeTest(String browser) throws Exception {
Browser.GetBrowser(browser);
}
tesng xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" parallel="tests" thread-count="2">
<test name ="FirefoxTest">
<parameter name="Browser" value ="Firefox"/>
<classes>
<class name="com.seleniumdata.zmartano.LoanDetails"/>
</classes>
</test> <!-- Test -->
</suite> <!-- Suite -->

You are passing browser object to void beforeTest() method in LoanDetails class,
So you need to pass #Parameter annotation on #BeforeMethod annotation:
public class LoanDetails {
WebDriver driver ;
public void commonMethod(String browser) throws Exception {
driver = Browser.GetBrowser(browser);
}
}
Call separate class in to Test class,
public class Browser {
private static WebDriver driver;
LoanDetails objLoan = new LoanDetails();
#BeforeMethod
#Parameters("Browser")
public void beforeTestUtility(String browser) throws Exception {
objLoan.commonMethod(browser);
}
#Test
public static WebDriver GetBrowser(String Browser)
{
if (driver != null)
return driver;
else if (Browser.equalsIgnoreCase("Firefox")) {
Log.info("Driver Initiated");
System.setProperty("webdriver.firefox.driver", Constants.geckodriver);
driver = new FirefoxDriver();
driver.get(Constants.URL);
Log.info("Application Opening");
driver.manage().window().maximize();
return driver;
}
else if (Browser.equalsIgnoreCase("Chrome")) {
Log.info("Driver Initiated");
System.setProperty("webdriver.chrome.driver", Constants.chromedriver);
driver = new ChromeDriver();
driver.get(Constants.URL);
Log.info("Application Opening");
driver.manage().window().maximize();
return driver;
}
return driver;
}
}

Execute one method in one test tag in parallel in testng

This is my class containing test method which I want to execute in parallel.
Each input from Data Provider is a new thread.
When I execute this method in 2 threads as Data Provider has 2 inputs, test hangs in one browser and other executes
public class DemoTest {
private static final ThreadLocal<WebDriver> webDriverThreadLocal= new InheritableThreadLocal<>();
private String baseUrl;
private String severity;
#BeforeMethod
public void beforeMethod() {
WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
driver.manage().window().maximize();
webDriverThreadLocal.set(driver);
System.out.println("In before method:"+Thread.currentThread().getId());
System.out.println("FF hashcode:"+driver.hashCode());
}
#DataProvider(name = "data-provider", parallel=true)
public Object[][] dataProviderMethod() throws IOException {
System.out.println("On dp");
new Object[] { 1, "a" },
new Object[] { 2, "b" },
}
public void testProgramOptions(Integer n, String s) {
WebDriver driver = webDriverThreadLocal.get();
baseUrl = "http://www.google.com/";
driver.get(baseUrl);
System.out.println("method f id:"+Thread.currentThread().getId()+" n:"+n+" s:"+s);
//test continues
}
#AfterMethod
public void afterMethod() {
WebDriver driver = webDriverThreadLocal.get();
System.out.println("In after method for id:"+Thread.currentThread().getId());
driver.quit();
}
}
This is testng.xml
<suite name="Suite" parallel="methods">
<test name="prelogin" >
<classes>
<class name="DemoTest"></class>
</classes>
</test>
</suite>
