Modifying a Data definition
After you create and publish a Data definition in HCL DevOps Test Hub (Test Hub), you can modify the fields or the configuration of the generators in an existing Data definition when you want to change the structure of the test data.
Before you begin
- Ensured that you are assigned a role as a Project Owner or Tester in the project. See Managing access to the server projects.
- Created a Data definition. See Creating an empty Data definition.
About this task
You can modify a Data definition after you open it for editing. After you make the modifications, you can save the Data definition, and either preview or generate test data with the changed data structure. If you want to commit the changes you made to the Data definition, you must publish the changes to the project repository. When you publish the changes they become visible to other project members. This way, other project members can access and use from the updated Data definition. When you or other members of the project edit the same Data definition, you can view an icon with the initials of the member in the Data definition page.
The Changes page also lists the conflicting edits when another member publishes their edited Data definition first. When a member with conflicting edits tries to publish the edited Data definition, an error about conflicting changes is displayed. However, the member can use the Save as option in the Changes page to save and publish a copy of the Data definition with a different name. The member must then discard the edits that were made to the original Data definition.
