Test Data

Test data is the set of input values your test steps use — usernames, passwords, search terms, amounts, dates, and so on. TestFlair lets you define test data per step, reuse data across a project, and let AI generate realistic values for you.

Where Test Data Lives

Test data is attached to individual test steps. When you open a test case in create or edit mode, each step has a data button that opens the Test Data dialog for that step.

Adding Test Data to a Step

In the Test Data dialog, each variable is one row with three required fields:

Field	Description
Data Type	The kind of value — String, Integer, Short, Long, Float, Double, Number, or Boolean.
Variable Name	The name used to reference the value in the step (e.g. username, password). Up to 100 characters.
Value	The actual value. The input adapts to the type — Boolean shows a True/False dropdown, numeric types show a number input, and any field named like a password is masked with a reveal toggle.

tip

There is no dedicated Date, Email, or URL type — store those as String. The variable name is what tells the generated script how to use the value, so signupEmail or checkoutUrl reads clearly even though the type is String.

• Click + Add Test Data to add another row.
• Use the trash icon to remove a row.
• Click Apply to save your changes back to the step. The button stays disabled until you make a change.

tip

Give variables clear, consistent names. The same names are reused when TestFlair generates a test script from the test case, so loginEmail reads better in generated code than field1.

Data Sources

Every value carries a source badge so you always know where it came from:

Source	Meaning
Custom	You entered the value by hand.
AI Generated	TestFlair generated a realistic value from your project context.
File	The value was imported from a data file (the filename is shown when available).

Reusing Project Test Data

To avoid re-typing the same values, click the Replace icon on a row to pick from your project's existing test-data library:

1. A picker opens showing every saved variable in the project — Data Type, Variable Name, Value, and Source.
2. Filter the list, select the variable you want, and apply it to the step.

This keeps shared values (a standard test account, a base URL, a sample SKU) consistent across many test cases.

AI-Generated Test Data

TestFlair can fill in realistic test data automatically based on your project context (uploaded documents, URLs, and descriptions). AI-generated values appear with the AI Generated badge so you can review them before running a test. You stay in control — edit or replace any generated value at any time.
