Please make sure your code passes all tests. Our test code coverage system will fail if these conditions occur:

1. The overall code coverage drops below the target threshold of the repository
2. Any file in the pull request has code coverage levels below the repository threshold
3. Merge conflicts

The process helps maintain the overall reliability of the code base and is a prerequisite for getting your PR approved. Assigned reviewers regularly review the PR queue and tend to focus on PRs that are passing.

CONTRIBUTING.md

Read our CONTRIBUTING.md file. Most importantly:

1. PRs with issues not assigned to you will be closed by the reviewer

I have added tests and translations.
Please let me know if there are changes.

@MahendraDani since we are not showing the users beforehand what characters must be there while creating a password, you should add these texts in red colour below the password field, which will turn green with a check mark if that param is fulfulled

Like this:

• ❌Password should be of atleast 6 characters
• ❌one lowercase letter
• ❌one uppercase letter
• ❌one numerical value
• ❌one special character.

When one or more of these params are fulfilled

• ✅ Password should be of atleast 6 characters
• ✅ one lowercase letter
• ✅ one uppercase letter
• ✅ one numerical value
• ✅ one special character.

Showing the user after he is trying to submit the registration form, that their password is incorrect, isn't good from the UX perspective.

@rishav-jha-mech
Should I also use icons for ✅ and ❌ or just show text?

[rishav-jha-mech]

@MahendraDani use mui for icons

@rishav-jha-mech
I created the UI as suggested by you, following is the demo

screen-capture.2.mp4

[rishav-jha-mech]

@MahendraDani Good one !, increases the spacing between the first validation text password input field, and reduce the spacing b/w validation texts, also there is too much space b/w the last validation text and confirm password, fix that too then we will do a code review

[MahendraDani]

@rishav-jha-mech I have improved the spacing between validation checks.
