Use cases where RealTestData is a great choice to work with

RealTestData - Safety, Speed, Accuracy in Test Data Generation.

RealTestData helps in many different types of testing. Here are some usecases which represent different testing types.

1. Performance Testing

Scenario: Load Testing a Banking Application

Use Case A banking application needs to process thousands of customer transactions per minute.

RealTestData Usage Generate large datasets of realistic IBANs, credit card numbers, and transaction details. Ensure referential integrity, so that ZIP codes, phone numbers, and addresses match correctly. Export the data in SQL format for direct database import.

Goal Test system performance under high transaction loads.

Test Steps Generate 10,000 unique customer profiles using RealTestData. Create realistic product carts with different quantities and item types. Generate valid and invalid credit card numbers. Simulate API requests for checkout. Measure response time and server performance.

Expected Outcome Response time should be below 2 seconds. System should handle at least 5,000 concurrent requests without crashing. Invalid credit card data should return HTTP 400 Bad Request.

Scenario: Stress Testing an E-commerce Checkout System

Use Case An online store wants to test its checkout page under peak sales.

RealTestData Usage Generate realistic names, addresses, emails, credit card details, and different cart sizes. Include negative test data (e.g., invalid credit card numbers, missing ZIP codes). Export data in JSON format to simulate real API requests.

Goal Ensure smooth checkout experience under heavy traffic.

2. Unit Testing

Scenario: Testing an Address Validation Service

Use Case A logistics company needs to validate user-entered addresses.

RealTestData Usage Generate valid addresses from different countries. Create edge cases like missing ZIP codes or incorrect city-state mappings. Export in CSV or JSON format for testing different APIs.

Goal Ensure the address validation logic works for all countries.

Test Steps Use RealTestData to generate a dataset with valid and invalid addresses. Send API requests to the /validate_address endpoint. Check if the system correctly identifies valid and invalid addresses.

Expected Outcome Valid addresses return HTTP 200 and “status”: “valid”. Invalid addresses return HTTP 400 and “status”: “invalid”. Edge cases (e.g., missing street names, incorrect ZIP codes) are properly flagged.

Scenario: Testing an Email Verification Feature

Use Case A SaaS platform needs to verify if emails are properly formatted.

RealTestData Usage Generate realistic email addresses with proper domains. Include negative test cases like emails missing the ‘@’ symbol or with special characters.

Goal Ensure that only valid email formats pass the verification.

3. Security Testing

Scenario: Testing User Authentication & Password Strength

Use Case A fintech app needs to test its password security rules.

RealTestData Usage Generate passwords with various complexities (upper/lower case, numbers, special characters). Include negative test cases (e.g., short passwords, dictionary words). Export as CSV or Excel for bulk testing.

Goal Ensure that weak passwords are rejected and strong ones meet security standards.

Test Steps Generate a dataset of strong and weak passwords. Send password inputs to the /register endpoint. Ensure strong passwords are accepted, weak ones are rejected.

Expected Outcome Weak passwords should trigger an error. Strong passwords should allow account creation. No SQL injection vulnerabilities.

Scenario Penetration Testing with Fake Identities

Use Case A fraud detection team needs a dataset of fake yet realistic identities.

RealTestData Usage Generate valid but simulated passport IDs, credit card numbers, and IBANs. Ensure referential integrity (e.g., passport IDs match country-specific formats). Export in SQL for database security testing.

Goal Test the system’s ability to detect fake or stolen identities.

Scenario Data Privacy and Anonymization Testing

Use Case A healthcare app must ensure its database contains no real patient data.

RealTestData Usage Generate realistic patient names, birthdates, and medical record numbers. Use composite fields to create realistic but non-traceable personal identifiers.

Goal Ensure the system can handle anonymized test data while maintaining integrity.

Scenario GDPR Compliance for Customer Data Storage

Use Case A European business needs to validate its data handling under GDPR.

RealTestData Usage Generate test customer data for different EU countries. Ensure data fields match country-specific rules (e.g., IBAN formats, social security numbers).

Goal Verify that customer data is stored, processed, and deleted correctly.

Test Steps Generate GDPR-compliant test data with fake but valid-looking names, emails, and national IDs. Register users and track how their data is stored. Send data deletion requests. Verify if data is actually removed.

Expected Outcome Data deletion requests should return HTTP 200. Deleted user data should be unrecoverable.

5. Negative & Edge Case Testing

Scenario Handling Incorrect Inputs in Web Forms

Use Case A social media platform must prevent incorrect user registrations.

RealTestData Usage Generate valid and invalid names, addresses, and email formats. Test for long names, missing fields, or special characters. Export in CSV or JSON for automated input testing.

Goal Ensure the system correctly flags invalid inputs.

Scenario Handling Extreme Data Cases in CRM

Use Case A CRM system must handle long names, edge-case phone numbers, and incorrect data.

RealTestData Usage Generate overly long names, ZIP codes, and emails to test system limits. Include non-existent area codes to check error handling.

Goal Ensure the CRM gracefully handles unexpected inputs.

Test Steps Generate names with over 100 characters. Generate email addresses with special symbols. Send these inputs to the user registration API.

Expected Outcome Names over 50 characters should trigger a warning. Emails with multiple @ symbols should be rejected. Invalid phone numbers should return an error.

6. Regression Testing

Scenario Ensuring Backward Compatibility in a Payment System

Use Case A payment provider is updating its backend and needs to test with old transaction data.

RealTestData Usage Generate past credit card transactions, IBANs, and payment histories. Use negative test cases (e.g., expired credit cards, invalid IBANs).

Goal Ensure old data remains compatible after updates.

Scenario Verifying Data Export Formats

Use Case A business intelligence team relies on reports exported in various formats.

RealTestData Usage Generate datasets in CSV, JSON, XML, and SQL. Validate that exported data is formatted correctly and can be re-imported.

Goal Ensure accurate reporting across all formats.
