Use ReadyAPI assertions to validate response and request contents: response codes, header values, specific fields in JSON and XML response bodies, and so on. To learn more about available assertions and their parameters, see Assertion Reference.
For any test step, add one or multiple assertions to check if it gets and returns data in expected format and functions correctly.
Open a test step in the editor and click Add Assertion.

In the Add Assertion dialog, select an assertion category, pick an assertion, and click Add. The assertion will be added to the Assertions panel.
| Note: | Some assertions may be missing from the dialog. It happens because they are not applicable to the currently selected test step or operation. The Recently category of the dialog lists 5 recently used assertions. |
Configure and order your assertions in the Assertions panel.
You can clone assertions you used in a request or response and apply them to another test step in the same or another test case or project. To do this, click 
on the toolbar of the Assertions panel and configure the following options as needed and apply the changes:

Assertions |
A list of available assertions to clone. |
|
Target Project |
A project to clone the assertion to. |
|
Target TestSuite |
A test suite to clone the assertion to. |

|
Overwrite |
Assertions of some types can be added several times to a test step, while assertions of some other types can be added only once. The Overwrite option affects cloning of such “one-instance” assertions:
The option does not affect multiple-instance assertions: ReadyAPI always adds copies of these assertions to the assertion list. |
|
Clear Existing |
Removes any existing assertions with the same name. |
|
Open List |
Displays the list of updated test requests. |
The Assertions panel lists the assertions you added to a test step or operation. Here, you can add and modify the assertions.
