Coverage Validator - Branch Coverage
The Branch Coverage view displays statistics for each function that contains branching code that is being
monitored for code coverage. The data is displayed in a tree format with the
top level showing class and the second level showing the functions and methods
in each class. The data can be displayed by Class, by Function, by File, by Directory location, by
number of lines in function. In the picture shown below, pink functions have not
been visited, yellow functions have had some branches visited and cyan functions have had every branch visited.
Each line in the display shows the filename, number of branches in each function, number of branches
that have been visited in the function, the total visit count for the function containing the branch, and
the percentage of branches that have been visited for the function.
The colour coding
allows at a glance viewing of the branch code coverage of each function. The controls
at the bottom of the display allow the results to be sorted and to be viewed
graphically.
When a file is selected in the left hand pane, the source code
for that file is displayed in the right hand pane, with visited and unvisited
lines shown in the appropriate colours, so you can at-a-glance see which lines
have been visited.
A popup menu (right mouse button) allows each file to be
edited in a syntax coloured editor that highlights each line according to
the visit status of each line.
The popup menu also provides options for controlling the expand and collapse
state of the tree control.
This picture shows the Branch Coverage view expanded to
show the methods in each class.
