Test Data Management
How to manage local variables, global variables, test data profiles, environment parameters, API response variables, and random functions in ContextQA for data-driven and parameterized testing.
Who is this for? Testers and SDETs who need parameterized, data-driven testing — running the same test with multiple data sets without duplicating test cases.
ContextQA provides four complementary data management mechanisms: local variables scoped to one test case, global variables shared across the workspace, environment parameters that vary between deployment targets, and test data profiles for data-driven testing. All four use the same ${variableName} reference syntax in test steps, making it easy to move from a hard-coded value to a parameterized one without changing step structure.
For values that must be fresh and unique on every run — a new email address, a current timestamp, a random amount — ContextQA also provides random functions, which generate a new value each time the test executes.
Global variables, environment variables, and test data profiles are managed together in the Environment Data Management workspace. This page explains how each variable type resolves inside test steps.
Prerequisites
You have at least one test case created.
You have access to the workspace settings (you are a workspace member with Editor or Admin role).
For data profiles: you have a test plan in which to attach the profile to a test case.
Local Variables
Local variables are scoped to a single test case. They exist only during the execution of that test case and are not visible to any other test case. Use local variables for values that are specific to one test scenario — a dynamically generated ID, a test-run timestamp, an intermediate value computed from an API response.
Defining Local Variables
Open the test case.
Click the Settings tab (gear icon) in the test case editor.
Under Local Variables, click + Add Variable.
Enter the variable Name and optional Default Value.
Save the test case.
Alternatively, local variables are created implicitly when a REST API Call step stores its response: set "Store response in variable" to myVar and the variable myVar becomes available in all subsequent steps.
Using Local Variables in Steps
Reference local variables anywhere in a step description, URL field, or API call body using the ${varName} syntax:
Setting a Local Variable Dynamically
You can set or update a local variable at runtime using a Set Variable action in an AI Agent step:
Or capture a value displayed on the page:
The AI agent reads the specified element's text content and assigns it to the named variable. This captured value can then be used in subsequent steps or REST API calls.
Global Variables
Global variables are workspace-scoped — they are available to every test case in the workspace. Use global variables for values that are shared across many test cases but are not environment-specific: a default admin account email, a standard test product name, a default search query.
Creating Global Variables
Navigate to Settings → Global Variables in the workspace settings.
Click + Add Variable.
Enter the variable Name and Value.
Click Save.
Using Global Variables in Steps
Global variables are referenced with the same ${varName} syntax as local variables. If a global variable and a local variable share the same name, the local variable takes precedence within the test case.
When to Use Global vs Local Variables
Admin email used in 30+ test cases
Global variable
User ID returned by an API call in one test
Local variable
Default search term used across multiple test cases
Global variable
Intermediate calculation within one test
Local variable
Test data row values from a data profile
Local (auto-populated per profile row)
Test Data Profiles
Test data profiles enable data-driven testing: running the same test case multiple times, each time with a different set of input values. A profile is a table where each column is a named variable and each row is one complete test run.
Creating a Test Data Profile
Navigate to Environment & Data → Data Profiles.
Click + Create Test Data Profile.
Enter a Profile Name (e.g.,
LoginScenarios_MultiRole).Click + Add Column for each variable your test uses.
Enter the column name exactly as it will be referenced in the test steps (case-sensitive).
Click + Add Row for each data scenario.
Fill in the values for each cell.
Click Save.
Example Data Profile
Profile name: LoginScenarios_MultiRole
username
password
expected_dashboard_title
expected_role_label
admin@test.com
Admin123!
Admin Dashboard

manager@test.com
Manager456!
Manager Dashboard
Manager
viewer@test.com
Viewer789!

Billing Admin
When this profile is attached to a test case and executed, the test runs four times — once per row — with ${username}, ${password}, ${expected_dashboard_title}, and ${expected_role_label} substituted per row.
Attaching a Profile to a Test Case
Profiles are attached at the Test Plan level, not at the test case level:
Open the test plan.
In the test case configuration for the specific test case, find the Test Data Profile dropdown.
Select the profile to attach.
Save the test plan.
When the test plan executes, the attached test case runs once per profile row. Each run produces an independent execution record with its own screenshots, video, and pass/fail result.
Importing Profile Data from a Spreadsheet
If you have existing test data in Excel or CSV format, you can import it directly:
In the Data Profile editor, click Import from Spreadsheet.
Ensure your spreadsheet has column headers matching the profile's column names.
Upload the file.
ContextQA maps the columns and imports the rows. Review the preview and confirm the import.
Environment Parameters
Environment parameters are key-value pairs stored in an environment configuration. They represent values that differ between deployment targets — base URLs, API keys, database hostnames, feature flag settings.
Creating Environment Parameters
Navigate to Environment & Data → Environments.
Open an existing environment or click + Create Environment.
Under Parameters, click + Add Parameter.
Enter the Key and Value.
Select the Type:
Text — plain string. Displayed in the UI and available in logs.
Password — encrypted at rest. Masked in the UI and redacted from execution logs.
Save the environment.
Using Environment Parameters in Steps
Reference environment parameters with the ${ENV.KEY} prefix:
Environment Parameter vs Global Variable
Both can store reusable string values. The distinction is:
Environment parameters vary between environments (staging BASE_URL is different from production BASE_URL).
Global variables are the same across all environments.
If a value is the same whether running against staging or production, use a global variable. If it differs by environment, use an environment parameter.
Using API Response Data as Variables
REST API Call steps can capture response data and make it available to subsequent steps as variables. This is the primary mechanism for chaining API calls and mixing API interactions with UI interactions within a single test case.
Storing an API Response
In a REST API Call step, set the Store response in variable field to a variable name. The entire response object is stored under that name:
Accessing Response Data
The stored variable exposes the following sub-properties:
${loginResponse.status}
HTTP status code
200
${loginResponse.body.token}
Top-level JSON body field
eyJhbGci...
${loginResponse.body.user.id}
Nested JSON body field
42
${loginResponse.body.user.email}
Nested JSON body field
admin@test.com
${loginResponse.headers.content-type}
Response header
application/json
${loginResponse.headers.set-cookie}
Cookie set by the response
session=abc; Path=/
Chaining Multiple API Calls
This pattern — create test data via API, test the UI that displays it, clean up via API — produces tests that are fully self-contained and do not leave orphaned data in the test environment.
Generating Random Test Data with Random Functions
Random functions generate a fresh value every time a test runs. Use them when a step needs data that must be unique or realistic without you maintaining a fixed list — a new signup email on each run, a current timestamp, a random order amount, or a plausible name and address for a form.
Unlike variables, a random function is not a stored value you define ahead of time. You insert the function directly into a step's test data, and ContextQA evaluates it at execution time. Two runs of the same test produce two different values.
Random functions are evaluated at runtime, so the same test run never reuses a value across executions. This makes them ideal for fields that reject duplicates, such as email addresses or usernames.
Inserting a Random Function
Open the test case and edit the step whose test data you want to randomize.
In the test data field, open the value picker.
Select the Random value source.
Browse the functions by category, or search by name.
Select a function. If the function accepts parameters, enter values for them (for example, a length, a minimum and maximum, or a date format).
Apply the selection.
ContextQA inserts the function into the step as a braced expression, for example {cqaRandom.email('test.com', 'Jane', 'Smith')}. At execution time, the expression resolves to a generated value such as jane.smith47@test.com.
The Random value source is available anywhere you set a step's test data, including action steps, condition steps, and loop steps.
Syntax
Random functions use single braces and the cqaRandom prefix:
This syntax is distinct from the ${variableName} reference used by local variables, global variables, and environment parameters. You do not need to type it by hand — the value picker inserts the correct expression — but recognizing it helps when you read a step's test data.
Function Categories
ContextQA includes 167 random functions grouped into 18 categories. The value picker lists every function with a short description; the following table summarizes the categories and gives representative examples.

Functions with Parameters
Many functions accept parameters that shape the generated value. The value picker prompts you for each parameter when you select the function.
cqaRandom.date(7)
Offset days, format
A formatted date offset from today
cqaRandom.int(1, 10)
Min, max
An integer within the range
cqaRandom.alphanum(10)
Length
An alphanumeric string of the given length
cqaRandom.email('test.com', 'Jane', 'Smith')
Domain, first name, last name
An email address on the given domain
cqaRandom.phone('US')
Country
A phone number in the country's format
cqaRandom.creditCardNumber('visa')
Provider
A test credit card number for the provider
cqaRandom.image(800, 600)
Width, height
An image URL at the given dimensions
Functions without parameters — such as cqaRandom.uuid() or cqaRandom.firstName() — generate a value with no further input.
Example: Randomized Signup Test
Random functions make it possible to run a signup test repeatedly without duplicate-data conflicts:
Each run submits a unique name, email, and phone number, so the account-creation form never rejects the input as already registered.
Random Functions vs Variables
A value that must be unique or fresh on every run
Random function
A value that must stay the same across steps or runs
Variable (local, global, or environment)
A value reused by many test cases
Global variable
A value that differs by environment
Environment parameter
A value captured from an earlier step or API response
Local variable
Tips & Best Practices
Use password-type parameters for all credentials and tokens. Even in test environments, API keys, passwords, and session tokens should be stored as password-type parameters. This prevents them from appearing in screenshots, logs, or exported test data.
Build one data profile per functional scenario. Do not mix different types of test data in one profile (e.g., valid credentials and invalid credentials in the same profile). Keep each profile focused on one scenario type so the profile name is self-describing and test results are easy to interpret.
Use API calls for test data setup, not manual data entry. If a test requires a specific record to exist (a user, an order, a product), create it via a REST API Call step at the start of the test rather than relying on pre-existing test data that might be deleted or modified between runs.
Clean up after yourself with API teardown steps. Add REST API Call steps at the end of tests to delete records created during the test. This keeps the test environment clean across repeated runs and prevents tests from interfering with each other.
Document global variable purpose in the description field. As the workspace grows, it becomes hard to remember what each global variable is for. Add a clear description when creating global variables, including which test cases use them and when they should be updated.
Troubleshooting
A variable is showing as ${varName} in the screenshot rather than its value This means the variable was not resolved at runtime. Check that:
The variable name in the step exactly matches the variable name as defined (case-sensitive).
For local variables set by a previous step, confirm the previous step passed — failed steps do not produce variable output.
For environment parameters, confirm the environment was selected in the test plan.
A REST API response variable is accessible in one step but not in a later step Variable scope is sequential — a variable set by step N is available to all steps after step N. If you are referencing a variable before the step that sets it, reorder the steps.
The data profile is attached but the test case runs only once Confirm the profile is attached in the Test Plan configuration, not just viewed in the data profile list. The profile must be explicitly selected in the test case row within the test plan's suite configuration.
Password-type environment parameters are appearing in test step descriptions Password parameters are masked in the UI and in execution logs, but the test step description itself is not modified. If you have written the literal value of a password into a step description rather than using the variable reference ${ENV.PASSWORD}, it will appear in plain text. Always use variable references for sensitive values — never hard-code credentials in step text.
