Editing a Test Plan Template
One answer
Is possible to add a field in the Test Estimation Section of a Test Plan?
At the moment it is not possible to add fields to the Test Estimation section (or other pre-defined sections of a Test Plan). You can, however, add a custom section that consists of a rich text editor. In that editor you could create a table or other rich text content to describe your Test Estimation needs. To add a new custom section, click on the "Manage Sections" button above the Table of Contents in the Test Plan editor. There is a green "+" button ("Create Section") that allows you to add a custom section.
In version 2, we are also investigating additional custom sections (in addition to rich text ones) that may also help.
We've heard the request to provide additional customization before and this is something we will consider.
How to add a new Test Environment in the combo list?
Can you please clarify your question? Are you asking about how to add additional platform attributes (e.g., new Application Servers, Browsers, etc.)?
Prior to version 2 there is no UI to add new platform attributes or lab resource properties. In version 2, we plan to support a way to add new Lab Resource Properties (i.e., hardware and software attributes) via the System Properties.
Prior to version 2, I believe there is a workaround so do let me know if this is what you need.
There is a way to edit/customize the flow of Test Plan?
You can edit/customize the order of the sections in a Test Plan. Click on "Manage Sections" above the Table of Contents of a Test Plan. In the "Selected Sections" list there are up & down arrows that you can use to re-order the sections of your Test Plan.
If you wish to modify the order of your Test Plan template (so other test plans can be based on the template), go to the main Planning menu and choose "Manage Templates".
From there you can edit or create a template with the desired section order/flow.
