Hi Instructor,

I am confused with the following code. What is called? I was watching an video on ExtentReport. In the video, you created a new class called ExtentManager and in that you have created a method like this:

static ExtentReports reports;

public static ExtentReports getReports()
{
if(reports == null)
{
reports = new ExtentReports();

}

What is this concept? I know we can assign a reference to the object of a class.

For instance,

ExtentReports e = new ExtentReports();

Do you have any examples on ExtentReports getReports()? Or Can you provide me with a simple example?

Thanks,

A

Many test classes will be there. Each test class should come in 1 single report.

So 1 single report should have multiple test cases. This means just one object of report class should be formed. That is the reason, We have written code like that

Yes, I understood that we are creating a method that will include reports of all tests.

I am confused about this line you wrote in your code

public static ExtentReports getReports()

ClassName with method name.

Suppose I have a Dog class and when I want to assign a value to the reference variable after creating an object,

int height;

Dog d = new Dog();

d.height = 5;

But in your code for the method you are writing like

public static ExtentReports getReports()

I am confused with this function declaration. Can you please help me understand.

public static int add() -> returns integer

public static ExtentReports getReports() -> returns object reference of extent reports

So in function ExtentReports is the return type

Got it. That was very simple. :)
