Bug: When submitting contact info if name includes the word "error" then we get an error

Introduction

In this article, we will be discussing a bug that occurs when submitting contact information on a website. The bug is triggered when the name field includes the word "error". This can cause an error to be displayed, preventing the user from submitting their contact information successfully. We will be reproducing this bug using a specific example and exploring possible solutions to resolve this issue.

Reproducing the Bug

To reproduce the bug, we need to follow these steps:

Create a test account: Create a new account on the website with a name that includes the word "error". In this case, we will use the name "Sam Errorful".
Enter contact information: Enter the email address "chw9e@virginia.edu" and any other required contact information.
Submit the form: Submit the contact information form.

Expected Result

When the form is submitted, we expect to receive a confirmation message or have our contact information saved successfully.

Actual Result

However, when we submit the form with the name "Sam Errorful", we get an error message. This error message prevents us from submitting our contact information successfully.

Possible Causes

There are several possible causes for this bug:

Case sensitivity: The bug may be caused by the website being case sensitive when checking for the word "error" in the name field. This means that if the website is checking for "error" in a case-sensitive manner, it may not match the word "Errorful" in the name field.
Regular expression: The bug may be caused by a regular expression that is used to validate the name field. If the regular expression is not correctly configured, it may match the word "error" in the name field, causing the error message to be displayed.
Database query: The bug may be caused by a database query that is used to retrieve or update the contact information. If the database query is not correctly configured, it may return an error message when the name field includes the word "error".

Possible Solutions

There are several possible solutions to resolve this bug:

Remove case sensitivity: We can remove case sensitivity from the website by using a case-insensitive comparison when checking for the word "error" in the name field.
Update regular expression: We can update the regular expression to correctly match the name field and prevent the error message from being displayed.
Update database query: We can update the database query to correctly retrieve or update the contact information and prevent the error message from being displayed.

Conclusion

In conclusion, the bug that occurs when submitting contact information if the name includes the word "error" is a common issue that can be caused by several factors. By understanding the possible causes and solutions, we can resolve this bug and ensure that our contact information is submitted successfully.

Additional Information

Test account: The test account used to reproduce the bug is "Sam Errorful" with the email address "chw9e@virginia.edu".
Note: This is a test and should not be used for actual contact information.

Future Development

In the future, we can improve the website by:

Adding more validation: We can add more validation to the name field to prevent similar errors from occurring in the future.
Improving database queries: We can improve the database queries to correctly retrieve or update the contact information and prevent errors from occurring.
Testing for edge cases: We can test for edge cases to ensure that the website is working correctly and prevent similar errors from occurring in the future.
