Dynamic Parameters

Use dynamic parameters to run the same test with different values. Add a parameter table to the test and use its headers in your test steps. Each row in the table becomes a separate test iteration. For example, one test can use several usernames:

Username	Password
user1	pass1
user2	pass2
user3	pass3

The test runs three times, using the values from each row.

Three pieces work together:

• A parameter table stores the values.
• A parameter header names each value.
• A placeholder in a test step tells Testomat.io where to use the value.

Note

A placeholder must match its parameter header exactly. If it doesn’t, Testomat.io shows Undefined in place of the value.

Add Parameters to a Test

1. Open Tests and select the test.
2. Click the Extra button.
3. Select Add Parameter.
4. Enter the name of the parameter.
5. Add a Parameter header for each value you need. You can also click Add column.
6. Click Save.
7. Enter the values for each row.
8. Click Save.

The parameter table appears in the test, with one row per set of test data.

Edit Parameters

You can edit parameters from the test description or from the parameter menu.

From the Test Description

1. Click Edit next to the parameter.
2. Change the parameter name.
3. Click Save.
4. Click Edit Header.
5. Change the header name.
6. Click Save.

Note

When you rename a header, update every placeholder that uses the old name. A placeholder that no longer matches its header shows Undefined in the run.

From the Parameter Menu

1. Click the Extra button.
2. Select Add Parameter.
3. Edit the parameter name or header name.
4. Click Save.

Delete a Parameter

1. Click the Trash icon next to the parameter.
2. Click OK to confirm.

You can also delete a parameter from the parameter menu: open Add Parameter and click the Trash icon.

Note

Deleting a parameter removes its data from future test runs, so its iteration is no longer created.

Use Parameters in Test Steps

After adding the parameter table, connect its headers to your test steps with a placeholder.

1. Check the exact Parameter header name.
2. Open the test and click Edit.
3. Add the header name to a placeholder using either ${} or {{}}.
4. Click Save.

For example:

Enter an invalid Mobile Number ${Mobile No}

Open home page {{URL}}.

When the test runs, Testomat.io replaces each placeholder with the value from the current row.

Both placeholder formats work in steps and descriptions. In test titles, use ${}.

Where	${ParameterName}	{{ParameterName}}
Test title	Works	Not supported
Steps and description	Works	Works

Using ${} everywhere keeps the syntax consistent.
