How can I keep the variable alive across the project globally?

Question

I have a BaseClass.java which extends PageObject.java class i.e. net.serenitybdd.core.pages.PageObject;

Then I have two Page classes LoginPage.java and ProfilePage.java, these two also extending the same PageObject.java class

I have a function in BaseClass.java:

public String createTestUser() {
        testUser = "test" + getTimeStamp() + "@demo.com";
        return testUser;
    }

Then I have function in LoginPage.java class where I test login feature using above created user, like this

public void doLogin() {
username.type(baseClass.createTestUser());
password.type("test123");
submitBtn.click();
  }

Now I have to verify whether correct user is logged in or not so I have a function in ProfilePage.java class

public boolean VerifySuccessfulLogin(){
   return verifyWebElementXpath("//div[contains(text(),'"+baseClass.createTestUser()+"')]");
}

This test failed. To fix this I tried:

I created a variable and function in LoginPage.java as

public String userForTesting = null;

public String getTestUser(){
    if(userForTesting==null ){
    userForTesting = baseClass.createTestUser();
    return userForTesting;
}
else {
    return userForTesting;
    }
}

Now I changed boolean function in ProfilePage.java as

public boolean VerifySuccessfulLogin(){
   return verifyWebElementXpath("//div[contains(text(),'"+loginPage.getTestUser()+"')]");
}

Still it is failing. It is generating new user for this boolean function. I am new to Java I have got few responses here https://stackoverflow.com/questions/52953005/how-to-pass-values-in-java-from-one-class-to-another but none worked.

What am I doing wrong? The userForTesting variable stays alive within LoginPage.java but after that it becomes null and so boolean function always gets newly created user.

Update:

public class BaseClass extends PageObject {

private static BaseClass baseClassFinder = null;

public static BaseClass getInstance() { if (baseClassFinder== null) baseClassFinder= new BaseClass(); return baseClassFinder; }

}

This is giving me error:

Answer 1

You can have a static class called TestData, which will hold the test user.

public final class TestData {

    @Getter
    private static String testUser;

    public static void resetTestUser() {
        this.testUser = String.format("test%[email protected]", getTimeStamp());
    }
}

And on BaseClass, you can have a @BeforeSuite method:

@BeforeSuite
public static void creatingUser() {
        TestData.resetTestUser();
}

This way, you can access the test user anywhere with TestData.getTestUser(); And if you need to reset it during the suite, you can call TestData.resetTestUser();

OBS: @Getter comes from Lombok.

Answer 2

Everytime you are making a call to getTestUser or createTestUser, it creates a new String.

I would suggest share the created test user across the test classes where you need the user. You might think of doing so by the TestClass's instance.

Below is a link of the same by Krishnan. A lot of times I refer this article.

Hope this solves the issue.
