Step 8 - Code Coverage

Configure Code Coverage

First, activate Code Coverage either from the Overview panel or by selecting the menu "Settings / Sampling and instrumentation rules":

The "Sampling and instrumentation rules" dialog appears:

Please perform the following steps:

Select the "Enabled" checkbox,
add class "com.terrasoft.profilerj.*" to the included classes,
add "c:/profilerj/src" to the "Source Folders" table
download examples-src.zip from here and extract the content of the zip file to c:/profilerj/src.

Apply Code Coverage

Next, send the instrumentation rules to the remote VM. Click the toolbar item highlighted below or select the menu "remote VM / apply rules":

Resume Process

Next, resume Example01 by clicking " Resume Process". Wait until Example01 is suspended again. Simply "Synchronize status" until the menu item "Resume process" becomes activated again or watch the console output of Example01.

Create a snapshot

To create a snapshot, select menu item " Create snapshot". The snapshot will be automatically displayed. Select panel "Coverage" and you should see something like this:

90% of the lines containing code have been reached. Since constructor Example01(String) hasn't been invoked, only five out of six methods have been called (i.e. 83%).

Open source file

Now click button "open source file". A file viewer pops up, where green areas indicate reached code. Analogously, red areas stand for non-reached lines which do contain executable code.
