[Feature]: provide test fixtures for TestNG similar to JUnits @UsePlaywright functionality

[bpoplawski]

🚀 Feature Request

Please provide test fixtures for TestNG testing framework which would work similarly as in JUnit framework.
This could work similarly to @UsePlaywright, reducing boilerplate code.

In other words a similar funcitonality to Junit one provided here:
https://playwright.dev/java/docs/junit

Example

Example is to use annotation like suggested in : https://playwright.dev/java/docs/junit

@UsePlaywright
public class TestExample {
@test
void shouldClickButton(Page page) {
page.navigate("data:text/html,<script>var result;</script>Go");
page.locator("button").click();
assertEquals("Clicked", page.evaluate("result"));
}

Motivation

Motivation is a fact that TestNG is also broadly used

TestNG doesn't have the capability to provide fixtures easily. We would need to create a base class that test classes would need to inherit from which isn't ideal because java doesn't allow multiple inheritance. All the other ways to pass parameters to a test results in conflicts with other aspects of TestNG.

For example, if we use a @DataProvider annotation to provide Playwright fixtures, the user can no longer use @Parameters functionality of TestNG.

In my opinion, supporting TestNG will bring more maintenance headaches than is worth it because we don't know how the user is using TestNG.

As a workaround, you could use @UsePlaywright annotation and in your own base class, create an instance of the factory and configure Playwright objects yourself.
