              constructor(page) {
                this.page = page;
                this.usernameInput = page.locator('#username');
                this.passwordInput = page.locator('#password');
                this.loginButton = page.locator('button[type="submit"]');
              }

              async login(username, password) {
                await this.usernameInput.fill(username);
                await this.passwordInput.fill(password);
                await this.loginButton.click();
