Unable to understand branch coverage and line coverage for Android in Dashboard

Hello,

We have integrated Clover for Android in Eclipse IDE. We are able to generate the html report of the project. But when we open the dashboard of that html page we are not able to see the line coverage and branch coverage of the overall project. It is giving the coverage as per the package or class . We need for the overall project.

Can you please help us how to read the dashboard and understand various aspects of it.

Help Appreciated.

Thanks!

Hi Bhushan,

The dashboard itself is not configurable, however you can configure content of detailed reports for packages and classes. In order to do this, you'd have to use Ant and generate HTML report outside Eclipse. The task can contain one or more elements and you can choose which metrics shall be displayed in the report. Please see https://confluence.atlassian.com/display/CLOVER/clover-report#clover-report-Columns for more details. If you'd like to learn more about metrics and reports, I suggest a following lecture:

We need the line coverage and branch coverage of the overall project.

Strictly speaking, Clover does not have a line coverage metric. Instead of this, a statement coverage metric is available (which is quite similar in terms of granularity).

Another question is how do you interpret branch coverage - is it a coverage of branches only (i.e. decision blocks like "if") or is it a coverage of statements + branches. In my opinion it should be the latter one, but it's up to you.

In order to read coverage value for the whole project, you can generate XML report. In the beginning of the file you'll find a <project> tag, for instance:

&lt;coverage generated="1370605007732" clover="3.1.12"&gt;
   &lt;project timestamp="1370605007039"&gt;
      &lt;metrics conditionals="46" methods="31" classes="3" files="3" packages="1" coveredstatements="90" complexity="54" loc="285" ncloc="183" coveredmethods="31" coveredconditionals="39" statements="95" coveredelements="160" elements="172"/&gt;
...

You can calculate coverage as follows:

  • method coverage = coveredmethods / methods * 100%
  • statement coverage = coveredstatements / statements * 100%
  • branch coverage = (coveredconditionals + coveredstatements) / (conditionals + statements) * 100%
  • total coverage = coveredelements / elements

Note: a total coverage metric is described here.
