Test executions can be created in bulk on the Ketryx Test management page. To do so: 

1. Select the appropriate version from the version dropdown.
2. Select Test Cases for which you'd like to create Test Executions. This can be done by selecting all tests; or using the filter selection or Ketryx Query Language (KQL) in the search bar to narrow the list of Test Cases for selection.
3. Click the 'Create executions for selection' button at the top of the table.
