Coverage Validator Help


The DLLs tab displays source file coverage information for each DLL that contains hooked functions.


interactiveRead on, or click a part of the image below to jump straight to the help for that area.





The DLLs view is largely similar to the Coverage view except that the file list is structured as a hierarchy of DLLs and files rather than just a flat list of files.


As with many of the tab views, the display is split into two resizable panes.


the left side lists a summary of the DLL and file coverage data

the right side shows source code for any file selected on the left


We'll cover the file list and its popup menu first, and then the source code view.



The DLL and file list



Each line in the view displays the following:


the DLL or file name

the percentage of hookable lines that have been visited


the number of hooked lines in the DLL or file

This is not the same as the total number of lines in a file, which may include comments, declarations and white space.


Neither is it the same as the number of hookable lines since some lines or functions can be excluded from hooking.

The count also includes lines which should have been hooked but failed, for example because the instrumentation level was set low.


the number of different lines that have been visited


the total visit count for the file


This may be equal to the number of different lines visited unless you're counting each visit separately as seen below:




The statistics for each DLL is an aggregated view of all the files within it.


Files in a DLL are ordered by their full paths, not by the directories in which they are found.



Line colours


Each line in the list is colour coded to indicate one of the following:


the file has not been visited at all



the file has been visited to some extent



every hookable line in the file has been visited, i.e. 100% file coverage




none of the lines in the file could be hooked




Unhooked lines


Depending on what file or DLLs hook filters are set up, not all the hookable lines in a header file may attempt to be hooked.


Only those that are actually used (e.g. via macros or inlines) in the program may actually be hooked.


note By default, lines that could not be hooked don't stop the coverage from reaching 100%, but you can change this.


In this example below, the instrumentation level was set low ('incomplete but faster') to force significant numbers of unhooked lines.






Scrollbar visualisations


To the right of each pane, beside the vertical scrollbars, you'll see a coloured area which represents the coverage.


For the DLL and file list, the visualisation shows the coverage of each item in the list - reflecting the progress meters in the second column.




For the source code view, the visualisation shows the coverage of each line in the file




These visualisations provide a snapshot view of the whole list of files or the whole source file.


Irrespective of how much you can see in the DLL and file list or in the source code view, you can still get a global overview of the coverage distribution.



Window orientation


The horizontal or vertical orientation of the statistics and source code panes can be toggled with the orientation button.

Updating the display


Refresh instructionStep updates the display - as does the refresh button on the Tools menu and toolbar



Sort order


Descending instructionStep reverses the direction of the data, sorted by the names in first column



Expanding and collapsing the data


Expand All / Collapse All instructionStep switches any hierarchical view from collapsed to expanded view



Display settings


Highlight unvisited lines instructionStep highlights rows for any functions that have not been visited (on by default)


If switched off, unvisited lines appear white - or whatever colour you've set as the unselected colour.



File list menu optionsright_mouse_button


The popup menu is identical to that for the Branch Coverage and Functions view.


The following popup menu is available over the data area to add filters, edit code, or expand and collapse the view.





right_mouse_buttonMenu options: Instrumentation Filter


The instrumentation filter lets you add filters at different levels of granularity:




Exclude Filename instructionStep adds a new filter to the Source Files Filter settings, excluding it from the results of subsequent sessions

Exclude Directory instructionStep excludes all files in the same directory as the selected file

From the sub menu, choose the directory level at which you want to exclude files, right up to the drive specifier if you need to




Exclude DLL instructionStep excludes all files belonging to the same executable or DLL as the selected file

This adds a filter to the Hooked DLLs settings.



note Filters become effective at the start of the next session. Adding a filter during a session will show the relevant rows in grey so that you can see which items would be filtered, but the coverage results will continue to be included for the rest of the current session.



right_mouse_buttonMenu option: editing source code


Edit Source Code... instructionStep opens the default or preferred editor to edit the source code



right_mouse_buttonMenu options: collapse / expand trace


Expand or Collapse Entry instructionStep shows and hides the selected section in the view, the same as using the expand-symbol or collapse-symbolbuttons


Collapse All instructionStep completely collapses all sections


Expand All instructionStep expands all the sections



The file source code view


Clicking on a file in the DLL and file list, shows that file in the source code view on the right.


The source code uses syntax highlighting by default, with the background colour of the line indicating if the line has been visited, is unvisited or could not be hooked.


Icons are displayed next to hooked and unhooked lines indicating visit and hook status and visit counts are shown in-line with the code.


Hovering over a line for a short period of time shows a tooltip with the number of visits to the line.


Contiguous groups of lines can be collapsed and hidden from view.



Source code file information


On the right hand panel, above the source code, you'll find some information about the source file





The details shown include the following:


'quick view' details for visited and unvisited lines, pink for unvisited, light green for partial visited, and dark green for 100% visited

tab-directories-file-info-dial           tab-directories-file-info-dial-covered



the source code filename and the executable or DLL to which it belongs



the same statistics as seen in the left hand panel




Browsing visited and unvisited lines


next-unvisted instructionStep show the previous and next unvisited line of code in the file

b_f7 and b_shift + b_f7 also navigate forwards and backwards when the source code has focus.

next-visited instructionStep show previous and next visited line of code in the file

The arrows are grey when disabled.


b_f8 and b_shift + b_f8 also navigate forwards and backwards through the visited lines.



Line instructionStep step by individual lines of code

Group instructionStep step by groups of contiguous visited or unvisited lines



Keyboard access: Find and Goto


When the data view or the source code view has focus, some keyboard access is available to search for DLLs, source code, or to navigate to numbered lines.



Find filename in data view


In the data view, b_ctrl + b_f displays a dialog that will allow you to search by full or partial match for a DLL path





Find text in source view


In the source code view b_ctrl + b_f lets you search by full or partial match anywhere in the file





Goto line in source view


In the source code view, b_ctrl + b_g displays a goto-line dialog
