Random Test Data Generator Tutorial Part 1: Complete Beginner's Guide to Generating Fake Data
Learn how to use the Random Test Data Generator to create realistic fake data for testing. Step-by-step guide with examples for JSON, CSV, SQL, and XML formats.
Random Test Data Generator Tutorial Part 1: Getting Started
Welcome to our comprehensive tutorial series on the Random Test Data Generator! This powerful, free tool helps developers, testers, and data analysts create high-quality, realistic fake data for various purposes including database population, UI testing, and API development.
What You'll Learn in This Series
- Part 1: Basic setup and generating your first dataset
- Part 2: Advanced field configuration and customization options
- Part 3: Export formats, constraints, and professional workflows
Prerequisites
- Basic understanding of data formats (JSON, CSV, SQL, XML)
- No programming experience required
- Modern web browser (Chrome, Firefox, Safari, Edge)
Objective
By the end of Part 1, you'll be able to:
- Generate basic test data with default fields
- Export data in multiple formats
- Understand the tool's interface and core features
Step 1: Understanding the Interface
The Random Test Data Generator interface consists of three main sections:
!Main interface overview with default fields
Step 2: Your First Data Generation
Default Setup
The tool comes with three pre-configured fields but soon you will have an option to store default setup by logging into the portal:
- id: UUID (Unique identifier)
- first_name: First Name
- last_name: Last Name
Generate Basic Data
Expected Result: You'll see 10 records with unique IDs and realistic American names.
Step 3: Exploring Output Formats
JSON Format:
We support two type of JSON formats i.e. Array of Objects and Key Value pairs
[
{
"id": "123e4567-e89b-12d3-a456-426614174000",
"first_name": "John",
"last_name": "Smith"
}
]
CSV Format:
Switch the output format to CSV and regenerate. You can separate columns using Comma, Pipe, Semicolon or Tab.
id,first_name,last_name
"123e4567-e89b-12d3-a456-426614174000","John","Smith"
SQL Format
If you choose SQL Format, you can specify table name so that generated query can be updated.
CREATE TABLE fake_data (
id VARCHAR(255),
first_name VARCHAR(255),
last_name VARCHAR(255)
);INSERT INTO fake_data (id, first_name, last_name)
VALUES ('123e4567-e89b-12d3-a456-426614174000', 'John', 'Smith');
Step 4: Adding More Fields
Step 5: Exporting Your Data
