<p>Tests a registered extension to make sure it meets all necessary requirements for being published in the CloudFormation registry.</p> <ul> <li> <p>For resource types, this includes passing all contracts tests defined for the type.</p> </li> <li> <p>For modules, this includes determining if the module's model meets all necessary requirements.</p> </li> </ul> <p>For more information, see <a href="https://docs.aws.amazon.com/cloudformation-cli/latest/userguide/publish-extension.html#publish-extension-testing">Testing your public extension prior to publishing</a> in the <i>CloudFormation CLI User Guide</i>.</p> <p>If you don't specify a version, CloudFormation uses the default version of the extension in your account and region for testing.</p> <p>To perform testing, CloudFormation assumes the execution role specified when the type was registered. For more information, see <a href="AWSCloudFormation/latest/APIReference/API_RegisterType.html">RegisterType</a>.</p> <p>Once you've initiated testing on an extension using <code>TestType</code>, you can pass the returned <code>TypeVersionArn</code> into <a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_DescribeType.html">DescribeType</a> to monitor the current test status and test status description for the extension.</p> <p>An extension must have a test status of <code>PASSED</code> before it can be published.
