What is a Text Box?

A text box is a graphical control element that allows users to input text data. It is commonly utilized in forms where users can enter information such as names, addresses, or messages. Text boxes vary in size and can be customized to accommodate different lengths of input, making them versatile for various applications.

What are the Use Cases of a Text Box?

Text boxes serve numerous purposes in software applications. Here are some common use cases:

1. Data Input: Text boxes are widely used in forms to capture user input such as names, addresses, and other essential information.
2. Password Entry: For security, text boxes can be configured to hide input characters, allowing users to enter passwords safely during account logins.
3. Search Functionality: Many websites implement text boxes for search purposes, enabling users to enter queries and retrieve relevant results quickly.
4. Comments and Descriptions: Text boxes facilitate the entry of longer text, allowing users to provide detailed comments, reviews, or descriptions relevant to their submissions.
5. Username/Email Entry: Essential for account creation and login processes, text boxes are used to capture usernames and email addresses in a user-friendly manner.
6. Numeric Input: Certain applications may require numeric data entry, for which a text box can be validated to restrict input to numbers only.
7. Date and Time Input: Specialized text boxes can help users enter dates and times consistently, often employing format restrictions to ensure proper data entry.
8. Surveys and Form Fields: Text boxes play a critical role in surveys and forms, gathering feedback, preferences, and other data from users.
9. Text Editing in Documents and Editors: In text editors and word processing applications, text boxes are integral for editing and formatting text, allowing users to create documents effectively.
10. Chat Interfaces: Enabling real-time communication through message input.
11. Configuration Settings: Letting users specify values for preferences or settings.

What are the Types of Test Cases?

• Single Line Text Box: Designed for brief input, such as names or titles, this type allows users to enter data on a single line without wrapping.
• Multiline Text Box: Suitable for longer entries, multiline text boxes enable users to input larger amounts of text, such as descriptions or comments, allowing for text wrapping across multiple lines.
• Password Text Box: This type conceals user input to enhance security, making it ideal for password entry fields during authentication processes.

• Valid email address: Inputting a valid email address in a designated email text box.

Negative Test Scenarios for Text Boxes

Negative test scenarios are essential to ensure the robustness of the text box functionality. Here are some key scenarios to consider:

• Invalid Email Format: Input an incorrectly formatted email address, such as missing the “@” symbol, and verify that the system prevents submission.
• Exceeding Maximum Character Limit: Enter text that exceeds the defined maximum character limit to confirm that the text box rejects the input and displays an appropriate error message.
• Illegal Characters: Test the application’s response when special characters, such as &, %, or $, are entered into a text box that only accepts alphanumeric characters.
• Empty Required Fields: Attempt to submit a form with required text boxes left blank to ensure the system prompts the user with an error message indicating the fields must be completed.
• Inputting Malicious Code: Check the application’s handling of potential cross-site scripting (XSS) attacks by entering scripts or HTML tags into the text box and ensuring that it sanitizes or rejects the input.
• Excessive Whitespace Input: Inputting a string comprised solely of spaces should be evaluated to confirm that the system does not accept it as valid input.
• Without no input: Attempting to submit a form without any input in a mandatory text box.

Test Cases For Disabled TextBox

• Verify that a disabled text box cannot be interacted with (no typing allowed).
• Confirm the appearance of the disabled text box aligns with design guidelines (usually grayed out).

Test Cases For Enabled TextBox

• Ensure that an enabled text box allows users to enter and edit text.
