Usage

The Usage view shows where a selected element is used, for example in which test cases a variant is used and to which requirements it is linked. To display the usage of an element, right-click on the element and select Show Usage. To update the displayed information, click . The usage information of the selected element will be displayed until you right-click on another element and select Show Usage. Usage information can be displayed for the following elements:

assesslet
execution configuration
mapping
platform configuration
requirement
signal (channel, parameter, constant, measurement, assessment)
test case
test set
testlet
variant

The name of the selected element is displayed at the top of the usage tree. If the element is used in specific sections, a section heading like Test cases, Assesslets, or Requirements is displayed. Section headings are preceded by a blue arrow . Only those elements making use of the element above are listed; for example: if you have 40 requirements, and your selected element is only linked to the requirement "SPEC-13", only "SPEC-13" will be displayed.

Usage view showing which elements are using variant "dark ambient; AUTO 2 OFF 2 ON 2 OFF"

In the screenshot above, the variant dark ON is used in the test case dark ambient; ON 2 OFF 2 AUTO 2 ON. The variant is linked to the requirement SPEC-4 and is explicitly selected in the Common assesslet settings of the assesslet headlight ON if switch AUTO and dark, see Common Assesslet Settings - Variants. The Usage view works recursively. Thus, by clicking on the + next to the entry in the Usage view, you will get a list of all elements using this item.

For example, by expanding SPEC-4, all elements linked to it are displayed. When the usage of an element is already displayed, the element's name is dimmed and shows a recycle symbol like ; this element cannot be expanded once more.

Filter/search field

Regular Expressions

By default, the search is set to string search. To use regular expressions, select the Regular Expressions checkbox. For example, the term ^L.*(g|y)$ will search n element/object that begins with an L and ends with an g or an y. The search is not case-sensitive, see Common Regular Expressions.

Filter

Only the elements that contain the search phrase are displayed. The filter is only applied to the names of items that are or have been expanded.
