Explore how constructors in Python initialize objects automatically, differentiate default and parameterized constructors, and use self to manage instance variables versus class variables.

Understand Python inheritance: a child class gains the parent’s properties and methods, imports the parent, and calls the parent constructor to initialize values in automation frameworks.

Learn how to work with Python strings, including indexing, substring extraction, concatenation, in-operator checks, and split and trim using strip, left strip, and right strip.

Learn how to read and write text files with Python, using open, read, readline, and loops to print lines, while safely closing files to avoid memory leaks.

Learn to print a file line by line with the read line method and a while loop, or use read lines to load all lines into a list for iteration.

Learn to write data to text files in Python using with open, read lines, reverse the content, and write it back, with examples of read and write modes.

Explore pytest fixtures and their role in test setup, sharing reusable pre-work across tests. Learn function and module scopes, linking fixtures to tests for automated Playwright tests.

Discover how pytest fixtures manage scope—from function to session—use conftest for shared setup, and run tests with pytest to observe fixture behavior across files.

Learn how to use pytest fixtures to return values and manage setup and teardown with the yield keyword, including function and session scope and data injection into tests.

Learn to run pytest from the command line by file or function, enable logs with -s, skip tests with pytest.mark.skip, and run by tag with -m, preparing for CI/CD workflows.

Launch the chromium engine with the pytest playwright fixture, and run in headless mode by default. Open a new browser context, create a page, and go to Rahul Shetty Academy.com.

Learn to use the Playwright page fixture in pytest to auto-create browser, context, and page objects and navigate with page.go_to, with options for headless or headed modes and cross-browser usage.

Explore core locators in Playwright, using get by label and get by role to identify inputs, selects, and form elements, then fill credentials and choose options.

Understand limitations of get by label: inputs must be inside a label or linked by for and id. Use get by role and CSS selectors for buttons, links, and checkboxes.

Explore Playwright's autowait for automatic checks of visibility, stability, and events, including auto retrying assertions, to detect the sign-in error message without explicit waits.

Learn to run Playwright tests in Firefox by replacing Chromium, launching Firefox (headless or visible), and opening a new page to reuse the same test code.

Learn to create a dynamic Playwright script that logs in, scans product cards, identifies iPhone X and Nokia Edge by name, and adds them to the cart with count verification.

Learn to handle child windows in Playwright Python by creating a new page object for the child window and using expect popup inside a closure to interact with it.

Extract the email id from text by splitting on the at keyword and space, stripping spaces, then assert the actual value equals the expected value in a playwright python test.

Explore using the get by placeholder locator in Playwright Python to validate visibility and hidden states, including interacting with a hide button and asserting outcomes.

Learn to handle javascript alerts and popups in Playwright Python by using on events and dialog.accept, with lambda functions for clean, non-web dialog handling.

Explore how to identify frames with frame locator in Playwright, switch to the frame, access its page content, click the all access plan link, and verify happy subscribers text.

Identify the dynamic price column and rice row in a web table, extract the price, and validate that rice costs 37 using a Python Selenium approach.

Learn end-to-end web table handling in playwright by locating the price column with nth-of in a row, validating 37 with expect, and mastering hover mega menus.

Record and playback tests with playwright codegen to generate code from your web flow using a base url. Refine locators, replace unreliable selectors, and tailor code to your framework standards.

Obtain a token by posting a login payload with Playwright's APIRequestContext, asserting a 200 status with response.ok, extract token from JSON body, and reuse it in create_order by calling get_token.

Refactor api utils to create an order via a single Playwright instance, extract the order id from the response, and verify it appears in the order history page.

Dynamically locate the order id from the history table using Playwright Python, filter the row by text, and click the view button to verify details in an end-to-end test.

Intercept and mock API responses with Playwright to validate UI behavior without changing test data. Learn to simulate no orders by overriding JSON responses and revert to real calls.

Learn to intercept network calls with route.fulfill in Playwright to mock API responses and test edge cases such as zero orders.
