27. Reusable Test Fixtures & Base Test Isolation

BaseTest Lifecycle Fixture Pattern

public class BaseTest {
    protected static Playwright playwright;
    protected static Browser browser;
    protected BrowserContext context;
    protected Page page;
public void initSuite() {
        playwright = Playwright.create();
        browser = playwright.chromium().launch();
    }
public void initTest() {
        context = browser.newContext();
        page = context.newPage();
    }
public void cleanupTest() {
        if (context != null) context.close();
    }
public void cleanupSuite() {
        if (browser != null) browser.close();
        if (playwright != null) playwright.close();
    }
}
