How to use SQL Generator Online

1.  Fill in the editor "Your SQL template" and click on the "Generate" button.
2. The "SQL generated" editor will contain the result.
3. You have a "Field Tags" section which shows you the available tags that you can use
4. You can dowload your CSV files below the editor. 

Using tags

You can also use tag in a property name. The tag must be in a string, enclosed in double curly brackets. Example:

INSERT INTO Customers (CustomerName, ContactEmail, Address, City, PostalCode, Country)
VALUES ('{{name}}', '{{email}}', '{{street}}', '{{city}}', '{{postcode}}', '{{country}}');

Test SQL Object Generator Overview

Data Generator for SQL is a tool for software developers and quality assurance engineers who need to generate test SQL documents in bulk for software or service testing. The document's structure can be explicitly created or imported from an existing SQL file. For smart data creation, the application uses a data generation engine that enables complicated data generation and value-to-value dependencies. The user can make test data more realistic by using the built-in Value Library, which contains predefined lists (names, dates, cities, streets, currencies, email, statecodes, firms, and so on).

SQL Data Generator

The Data Generator data source is a built-in engine that generate many types of property values. This method eliminates the need to manually create data storages and populate them with data. Manually populating a database is a time-consuming and stressful task.
A test data creation tool enables business owners to try out and test their technologies before releasing them to the general market. It's recommended to avoid manual operations and instead use one of the above-mentioned test data creation solutions, which have a higher success rate.

Generate SQL from a Template

The SQL Generator uses a SQL template to generate data. Basic and custom settings are available in the SQL Generator's dialogue box. You can personalise the generator by altering the parameters as needed.
SQL Generator also includes Template and Preview dialogue boxes. By modifying the default script, you can customise the default template.

How Do You Create Various Name Test Data?

Each set is randomly generated to simulate real data.

Test data is actually the input given to a software program. It represents data that affects or is affected by the execution of the specific module. Some data may be used for positive testing, typically to verify that a given set of input to a given function produces an expected result. Other data may be used for negative testing to test the ability of the program to handle unusual, extreme, exceptional, or unexpected input. Poorly designed testing data may not test all possible test scenarios which will hamper the quality of the software.

Testing is an iterative part of the development process that it performed to ensure the quality of the code. During the development process you will need fake data similar to real data for testing purposes.

What is Test Data? Why is it Important?

Dummy Test data is actually the input given to a software program. It represents data that affects or is affected by the execution of the specific softwar feature. Some data may be used for positive testing, typically to verify that a given set of input to a given function produces an expected result. Other data may be used for negative testing to test the ability of the program to handle unusual, extreme, exceptional, or unexpected input.

Software Testing Methodologies

• Black Box Testing - A software testing method in which the internal structure/design/implementation of the item being tested is not known to the tester. These tests can be functional or non-functional, though usually functional. Test design techniques include: Equivalence partitioning, Boundary Value Analysis, Cause Effect Graphing.
• White Box Testing - A software testing method in which the internal structure/design/implementation of the item being tested is known to the tester. Test design techniques include: Control flow testing, Data flow testing, Branch testing, Path testing.
• Gray Box Testing - A software testing method which is a combination of Black Box Testing method and White Box Testing method.
• Agile Testing - A method of software testing that follows the principles of agile software development.
• Ad Hoc Testing - A method of software testing without any planning and documentation.

What to Look for in Mobile Testing Tools?

How do you choose the best tool for creating test scripts? Begin by focusing on the following characteristics, which are critical for successful mobile app testing.

• Multiple scripting languages are supported. It's critical to have a variety of test creation choices.
  This involves having a selection of scripting languages to pick from. Naturally, your QA staff should be able to work with those with whom they are already acquainted. As a result, look for a tool that supports a variety of programming languages.                
• You are developing tests for a variety of mobile operating systems. Look for a program that allows you to conduct your tests on many mobile platforms. It would be ideal for including a code reuse option, so you wouldn't have to write separate test scripts for each platform.
• Test creation choices that don't require any scripting. It is critical to creating tests without coding. This feature of mobile testing tools is beneficial to folks who do not have programming expertise. You may also develop tests very quickly this way.
• CI/CD tools are seamlessly integrated. Make sure your mobile testing tool is simple to integrate with the technologies you already use for your CI/CD procedures.
