Ans. 1. Using Playwright, testers can perform cross browser testing in different browsers like chrome,firefox, chromium etc. which involves running test scripts in different browsers one after another.

Playwright is helpful in automation testing of advanced web applications using React,NodeJs as well as in automation of more complex single page applications.

Playwright helps immensely in performing System testing which is also the end to end testing, involving navigation from the home page of the application to the last page of that application as well as interaction with different components of each page.

With the help of Playwright, testers can perform parallel testing using different browsers which involves running test scripts simultaneously in different browsers.

Using Playwright testers can keep a record of the test cases or scripts executed.

Playwright does not require the use of any wait command like explicit wait for running test scripts since it automatically performs wait actions.

Testers can perform image based testing like screenshot comparison,visual comparison through playwright.

Playwright can be used in performing automated regression testing by integrating with CI/CD pipeline to make sure that any code changes do not affect the existing functionality of the application.

Using Playwright automation scripts can be run in different operating systems like windows, Linux and MacOS.

Testers can also perform mobile testing effectively using Playwright

Ans. 1. Playwright is not compatible with Safari Browser.

Since it is relatively new to the market, sometimes effective test execution may not happen.

Although Playwright supports mobile application testing,it still does not support automation testing of native mobile applications.

Playwright is difficult to learn for those people who have zero knowledge of coding.

Not suitable for performing unit testing.

Playwright does not support cloud based testing.

Whenever testers do not perform cross browser testing, use of playwright becomes unnecessary.

For very small projects with limited budget usage of playwright is not justifiable.

Ans. Playwright supports API Testing,Parallel Testing,CrossBrowser Testing, System Testing, Component Testing, Functional Testing.

Ans. await page.locator(‘input[type=”text”]’).fill(‘Hello, world’);

await page.locator(‘input[type=”text”]’).type(‘Hello, world’);

Ans. await page.locator(‘selectorname’).clear();

Ans. await page.locator(‘selectorname’).innerText();

Ans. Using isVisible() method we can check if given element is displayed or not. Syntax: await page.locator(‘selectorname’).isVisible();

Ans. Using isChecked() method we can check if given element is selected or not. Syntax: await page.locator(‘selectorname’).isChecked();

Ans. Syntax to check whether button is enabled:

await page.locator(‘your-selector’).isEnabled();

Syntax to check whether button is disabled:

await page.locator(‘your-selector’).isDisabled();

Ans. The different assertions used in playwright are

expect(value).toEqual(expected)
expect(value).toBeTruthy()
expect(value).toBeFalsy()
expect(locator).toContainText(expected_text):
expect(locator).toHaveClass(expected_class)
expect(value).toBe(expected)

Ans. Using Assertion if the test fails the test execution stops.By using soft assert text execution continues even if the test fails and the test status will be marked as failed at the end of execution.

Ans. page.goto(‘https://example.com’);

await page.reload(); // Refresh your current page

await page.goBack(); // Takes one page backward based on browser’s history

await page.goForward(); // Takes one page forward based on browser’s history

Ans. await page.locator(‘your-selector’).contextMenu();

await page.locator(‘your-selector’).click({ button: ‘right’ });

Ans. await page.locator(‘your-selector’).dblclick();
