Fixed Issues

$ #27456
PROPOSAL:
#27456 (comment) (originally from: #27456 (comment))

Tests

• Open Expensify & log in to an account (User B)
• Sign into Android native / Android mWeb (User A)
• Send a message from User B to User A
• In LHN, the message received should be shown in bold (User A)
• Open the chat (User A)
• Verify that the green line marker is displayed where it should and does not jitter (User A)
• Go back to the LHN (User A)
• Open the chat again (User A)
• Verify that the green line has disappeared (messages have been read) (User A)
• From user B, send multiple messages to User A
• Verify that the green line is not shown for these new messages (User A)
• Manually mark the last and then semi-last messages as unread from the context menu, verifying the green line moves appropriately (User A)
• Go back to the LHN & open the chat again (User A)
• Verify that the green line is shown above the semi-last message (User A)
• Go back to the LHN & open the chat again (User A)
• Verify that the green line is not shown anywhere now (User A)
• Go back to the LHN
• Send a message from User B to User A
• Open the chat again (User A)
• Verify that the green line is shown above the new message (User A)
• Delete the message (User B)
• Verify that the green line is not shown anywhere now (User A)
• Repeat the process for Android Native & Android mWeb

PR Author Checklist

• I linked the correct issue in the ### Fixed Issues section above
• I wrote clear testing steps that cover the changes made in this PR
  • I added steps for local testing in the Tests section
  • I added steps for the expected offline behavior in the Offline steps section
  • I added steps for Staging and/or Production testing in the QA steps section
  • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
  • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
  • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
• I included screenshots or videos for tests on all platforms
• I ran the tests on all platforms & verified they passed on:
  • Android: Native
  • Android: mWeb Chrome
  • iOS: Native
  • iOS: mWeb Safari
  • MacOS: Chrome / Safari
  • MacOS: Desktop
• I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
• I followed proper code patterns (see Reviewing the code)
  • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
  • I verified that the left part of a conditional rendering a React component is a boolean and NOT a string, e.g. myBool && <MyComponent />.
  • I verified that comments were added to code that is not self explanatory
  • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
  • I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
    • If any non-english text was added/modified, I verified the translation was requested/reviewed in #expensify-open-source and it was approved by an internal Expensify engineer. Link to Slack message:
  • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
  • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is approved by marketing by adding the Waiting for Copy label for a copy review on the original GH to get the correct copy.
  • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
  • I verified the JSDocs style guidelines (in STYLE.md) were followed
• If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
• I followed the guidelines as stated in the Review Guidelines
• I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
• I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
• I verified any variables that can be defined as constants (ie. in CONST.js or at the top of the file that uses the constant) are defined as such
• I verified that if a function's arguments changed that all usages have also been updated correctly
• If any new file was added I verified that:
  • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
• If a new CSS style is added I verified that:
  • A similar style doesn't already exist
  • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(themeColors.componentBG))
• If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
• If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
• If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
• If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
• If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
• If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

Could you please add a test for

• Marking message as unread manually case
• Deleting a message case

And add screenshots for all platforms - iOS, Desktop and Web

[MonilBhavsar]

@situchan 👋

[artus9033]

@MonilBhavsar updated the PR.

[artus9033]

@situchan friendly reminder for you to review this PR 👋

[situchan]

reviewing tomorrow. Can you please fix TS error?

[situchan]

Also, please pull main as the branch is behind

[artus9033]

@situchan thanks for the response. Done, it seems like there have been some changes made to the tests in the meantime and the old history was to blame. After pulling main, npm run typecheck passes locally - the PR is ready for review.

[MonilBhavsar]

@situchan 👋

[situchan]

This is out of scope but just to note:

delete.unread.mov

[situchan]

Just to note this is expected: (same behavior as main)

1. send message A and then B
2. mark B as unread
3. mark A as unread
4. delete A
5. B is marked as unread briefly and then disappears (all are read)

delete.2.mov

[situchan]

I'd like to confirm that this is expected as well. There's inconsistency between self-unread and unread.

Self-unread message:

• after scrolling down to latest manually, LHN is still bold
• after scrolling down by clicking "New messages" badge, LHN gets unbold

Screen.Recording.2023-11-30.at.12.24.16.PM.mov

---

Unread message from others:

• after scrolling down to latest manually, LHN gets unbold
• after scrolling down by clicking "New messages" badge, LHN gets unbold

Screen.Recording.2023-11-30.at.12.25.40.PM.mov

[situchan]

LHN is still bold while no unread chat on mobile
@MonilBhavsar I think others can be out of scope but not sure if this should be handled here since it causes inconsistency.
This doesn't happen on web.

We have this issue for fixing inconsistencies with delete message case #31714

I think others can be out of scope but not sure if this should be handled here since it causes inconsistency.
This doesn't happen on web.

Are you able to consistently reproduce? I am not.
If yes, we can open a new issue and work on it there

[MonilBhavsar]

#31627 (comment)
This is great point! I'll create a new issue. Thanks!
