OtfWorkflowDesigner

EDITING...

Overview

The Workflow Designer is the central interface to input and arrange OTX nodes. It helps the authors create, edit and understand the test sequences graphically. The following main tasks will be implemented with the OTX Designer:

• Specification
• Realization
• Documentation

The structure and functions of the Workflow Designer are described in the following sections.

Structure

In the Workflow Designer, test sequences can be edited graphically, see the image below. The Designer may consist of one or many tabs, each tab corresponds to a procedure ( a flow sequence/a workflow???). Within a sequence, the various activities (OTX nodes) are drawn together into a sequence on a white page. These activities can be configured through the dockable Properties window or the Properties dialog box. The activities are executed sequentially from top to bottom.

The sequences are presented in the form of a generic flowchart. This means that the author has only the ability to add individual items to, edit and adjust the presentation details. However, it has no direct influence on the position of the elements. It may include such activities so do not move the mouse to another location, such as in MS Visio. This supports the generic approach of OTX and has the following advantages:

• The representation is generated solely from the OTX data without further meta data
• The depiction of the sequence is independent of the flavor of the author
• The same OTX sequence is the same on different computers
• The author does not have to worry about layout details

A flow consists of the head region and the drawing page. In the head region, the relevant information of the procedure are presented below:

• Name
• Parameter (In-, Out- and InOut- parameters)
• ValidFor
• Implemented Signature
• Specification

The drawing page contains the actual sequence of a procedure. It consists of a series of activities, see the image above.

Handling activities

Adding activities

To add an activity to the sequence, please follow the instructions as described below:

• Find the corresponding activity from the Toolbox.
• Drag the activity into the sequence, note that there will be green plus signs displayed at the valid locations for this activity .
• Drop activity on one of the plus sign sothat the plus sign is replaced by the icon of the activity.
• If the insertion is not in the visible range of the sequence, drag the activity on one of the blue arrows at the edges of the Workflow Designer.
• The drawing page will be scrolled toward the appropriate direction to to show the unseen range, move the mouse out of the blue arrow to stop scrolling.
• Drop the activity at the valid location sothat the activity is generated in the appropriate place.
• If you want to configure the activity, please use the Properties window (see instruction below).
