Length Configuration

Fixed Length Strings

Generate strings of exactly the same length:

• Set both min and max to the same value (e.g., 10 and 10)
• All generated strings will be exactly that length
• Perfect for IDs, codes, or consistent formatting
• Example: All strings will be exactly 8 characters

Variable Length Strings

Generate strings with random lengths within a range:

• Set different min and max values (e.g., 5 and 15)
• Each string will have a random length within that range
• Creates more realistic, varied test data
• Example: Strings between 10-50 characters for names

Common Length Ranges

• Short IDs: 6-8 characters (e.g., user IDs, codes)
• Medium Text: 10-30 characters (e.g., usernames, titles)
• Long Text: 50-200 characters (e.g., descriptions, comments)
• Very Long: 200-1000 characters (e.g., articles, content blocks)

Quantity Guidelines

Small Quantities (1-10)

• Quick manual testing and verification
• Individual test cases
• Sample data for demonstrations
• Prototype content

Medium Quantities (10-100)

• Form testing with multiple entries
• List and table population
• UI component testing
• Basic database seeding

Large Quantities (100-1000)

• Comprehensive database seeding
• Performance testing datasets
• Pagination testing
• Search functionality testing

Very Large Quantities (1000+)

• Load testing and stress testing
• Big data simulations
• Scalability testing
• Production-like datasets

Character Set Information

Alphanumeric Characters

Generated strings use a mix of:

• Uppercase Letters: A-Z (26 characters)
• Lowercase Letters: a-z (26 characters)
• Numbers: 0-9 (10 characters)
• Total Pool: 62 possible characters

Why Alphanumeric?

• Safe for most systems and databases
• No special characters that might cause issues
• URL-safe and filename-safe
• Works in all programming languages
• Easy to read and copy

Best Practices

Length Selection

• Match your actual data requirements (e.g., username length limits)
• Test with both minimum and maximum lengths
• Use variable lengths for more realistic testing
• Consider your database field constraints
• Test edge cases with very short and very long strings

Quantity Selection

• Start small (10-20) to verify the output format
• Generate enough data to test pagination and scrolling
• Consider your system's performance limits
• Generate in batches for very large datasets
• Match production data volumes for realistic testing

Using Generated Text

• Copy all strings at once for bulk import
• Use in CSV files for database imports
• Feed into test automation scripts
• Paste into forms for manual testing
• Use as placeholder content in designs

Testing Strategies

• Generate multiple batches with different lengths
• Test with fixed lengths for consistency checks
• Use variable lengths for realistic scenarios
• Combine with other test data types
• Save generated sets for regression testing

Performance Considerations

Generation Speed

• 1-100 strings: Instant generation
• 100-1000 strings: 1-2 seconds
• 1000-10000 strings: 2-5 seconds
• 10000+ strings: May take longer, consider batching

Browser Performance

• Very large quantities may impact browser memory
• Copy and clear after generating large sets
• Generate in batches if you need 50,000+ strings
• Close other tabs for better performance with large sets

Integration Examples

Database Seeding

Generate data for database population:

1. Set length range matching your field constraints
2. Generate quantity matching your test needs
3. Copy all generated strings
4. Import into database via SQL or seeding script
5. Use for testing queries and performance

API Testing

Create test data for API requests:

1. Generate strings matching API field requirements
2. Copy generated data
3. Use in API request payloads (JSON, XML, etc.)
4. Test API validation and error handling
5. Verify API responses with varied inputs

UI Component Testing

Test UI with varied content:

1. Generate strings of different lengths
2. Paste into UI components (inputs, textareas, etc.)
3. Test layout with short and long content
4. Verify text truncation and overflow handling
5. Check responsive behavior

Tips & Tricks

• Use fixed length (min = max) for consistent IDs or codes
• Use variable length for more realistic test data
• Generate multiple batches with different settings for variety
• Copy to spreadsheet for easy manipulation and organization
• Save generated sets for reuse in regression testing
• Test your UI with both very short and very long strings
• Use for password testing (though not for actual passwords)
• Generate unique identifiers for test records
• Create realistic-looking but meaningless data for demos
• Combine with other tools for comprehensive test data creation

Common Scenarios

Scenario 1: Database Seeding

You need to populate a users table with 500 test records. Set length to 8-20 (for usernames), quantity to 500, generate, and import the strings into your database as username values.

Scenario 2: Form Validation Testing

Test a form that accepts 5-50 character inputs. Set min to 5, max to 50, quantity to 20, generate, and use the strings to test form validation, ensuring it accepts valid lengths and rejects invalid ones.

Scenario 3: UI Layout Testing

Test how your UI handles various text lengths. Generate strings with min 1, max 200, quantity 50, and paste them into your UI components to see how they handle short, medium, and long content.

Scenario 4: API Load Testing

Create test data for API load testing. Generate 1000 strings with length 10-100, copy all, and use them in your load testing tool to send varied data to your API endpoints.
