The provided code uses Playwright for browser automation with a synchronous API. Key points:

• A Chromium browser is launched in UI mode (headless=False).
• Request interception is set up for URLs matching **/symbol_search/**, returning a mock JSON with a single symbol "SPY".
• A page is opened at the specified URL (in the code [link] — replace with the actual URL).
• After waiting, an element with a XPath locator is clicked, then a random ticker from a list is entered into the "Search" placeholder field, and Enter is pressed.

The second function test_2 calls test_1, waits, then clicks on user menu items, including the "Sign in" button.

Using route in Playwright allows mocking server responses for UI testing without a real backend. This is useful for isolating tests and controlling data.

To improve the code:

• Use Playwright's page.wait_for_selector instead of sleep for reliability.
• Replace XPath locators with more stable selectors.

Example of replacing sleep with wait:

page.locator("//*[ @id='header-toolbar-symbol-search']/div").click()
page.wait_for_selector("input[placeholder='Search']")

This will increase test stability.
