Description of Code / Doc Changes

• Created a test to verify that tabs can be hard reloaded and override any cache by using the keyboard shortcuts (CTRL/CMD + SHIFT + "r").

Process Changes Required

Mark the relevant boxes:

• Adds a dependency (rerun pipenv install)
• Changes the BasePage
• Changes or creates a BOM/POM (name the object model): _
• Changes CI flow
• Changes scheduled Beta or DevEdition
• Changes Git hooks or Github settings
• Changes L10n harness

Screenshots or Explanations

1. We create a new browser and tab.
2. We navigate to the 'https://postman-echo.com/headers' website which allows us to view the headers sent in the http request through html elements.
3. Perform an action sequence to hold CTRL/CMD + SHIFT and press "r"
4. Check the html elements to verify that the 'If-None-Match header' is not present and checks that both the 'pragma' and 'cache-control' headers contain "no-cache".
5. This lets us know that the page will load without using cache.

Comments or Future Work

• We may want to consider making a test to check whether BFC (back-forward-cache) is being used or not after a hard reload.
• Since this test uses the website 'https://postman-echo.com/headers', we may have to consider in the future if the website is still active and working or not.
• It would be better to be able to check cache use without having to rely on loading a specific website.

Workflow Checklist

• Please request reviewers
• If this is an unblocker, please post in Slack.
• If asked to address comments, please resolve conversations.
• If asked to change code, please re-request review from the person who wanted changes.

Thank you!

Please move the keyboard short in lines 30-40 to modules/browser_object_navigation.py. Yours will be similar in structure to the keyboard shortcut for toggle_bookmarks_toolbar_with_key_combo()

Other than that, looks good. Nicely done solving how to check for overriding the browser cache.

Looks good. Thank you, Ruhan.
