In the field of software testing, test data generation is a crucial aspect. Manual data generation is not only time-consuming and labor-intensive, but also difficult to ensure the quality and diversity of data. Therefore, using an online test data generator has become the first choice of many testers.
In this article, we will introduce 6 awesome online test data generators to help you generate test data more efficiently.
1、Mockaroo
MockarooIt is an online data generation tool that provides more than 125 data types, including name, address, date, picture and more. Users can customize the data structure to generate test data that meets actual needs.

Features:
- Support for a large number of data types and custom structures
- Generate up to 1 million pieces of data at a time
- Supports multiple data export formats (e.g. CSV, JSON, SQL, etc.)
2、JSON-Generator
JSON-GeneratorFocuses primarily on generating test data in JSON format.
Online address:/
Features:
- Optimized for JSON: It has in-depth understanding and optimization of JSON data structure. Users can easily define complex structures such as JSON objects and arrays. For example, you can quickly generate a JSON data containing multiple nested objects and arrays for testing APIs or systems that handle complex JSON data.
- Visual Editing Interface: With an intuitive visual editing interface, even users without a deep technical background can get started quickly. Complex JSON data structures can be built with simple drag-and-drop and parameterization. For example, you can add a new JSON property, set the value type and range of the property, and immediately see an example of the resulting JSON data.
- Code Generation: In addition to generating JSON data directly, JSON - Generator can also generate code for generating JSON data. This is very convenient for developers who need to dynamically generate JSON data in their programs. Users can choose different programming languages (e.g. JavaScript, Python, etc.) to generate the corresponding code snippets.
3、SQL-Data Generator
SQL-Data Generator A tool designed specifically for generating test data for use in SQL databases.

Features.
-
Strong database compatibility: It supports many mainstream SQL databases, such as MySQL, Oracle, SQL Server and so on. No matter which database management system is used in your test environment, you can use SQL - Data - Generator to generate suitable data. For example, it can generate compliant insert statements or data files according to the specific data types and syntax rules of different databases.
-
Database Architecture Awareness: It can recognize database architecture information and generate valid test data based on table structure, field types, constraints and so on. If there are associative relationships (such as foreign key constraints) between tables in the database, SQL - Data - Generator can generate data that conforms to these relationships. For example, when generating order data and customer data, it will ensure that the customer ID in the generated order data matches the data in the customer table based on the customer foreign key relationship in the order table.
-
Data Update and Delete Simulation: In addition to generating insertion data, you can also simulate data update and delete operations in the database. Users can specify the rules and conditions for data updating and the range of deleted data, which are used to test the correctness and performance of the update and delete functions of the database. For example, it can be set to update the values of certain fields according to a certain ratio or delete part of the data according to specific conditions to simulate various situations in actual database operations.
4、Generatedata
GeneratedataIs an open source online test data generator , it supports more than 30 types of data , including name , email , address , phone number , etc., and supports a variety of export formats , such as CSV, SQL, JSON and so on. In addition it also supports custom data types and generation rules , users can create complex data structures to generate a large amount of test data. And it supports REST API, which allows easy data generation and integration.

Features:
- Open source, free
- Support for customized data types and generation rules
- Supports multiple data export formats (e.g. CSV, JSON, SQL, etc.)
5、Randat
RandatIt is a free online tool that generates tables containing randomized personal information such as name, age, occupation, salary, etc. The user simply selects the preferred columns and rows and clicks on the "Generate" button. The user simply selects the preferred number of columns and rows and clicks the "Generate" button to generate the table. The generated table can be exported in XLS, XLSX or CSV format for easy follow-up and Randat is ideal for generating test data with specific attributes.
