Does clover support to read and write clover.db and coverage recording files from ftp server?

[Juan LS]

Currently, we are trying to use clover as the code coverage tools for our distributed system. Which requires a network file system to share the clover.db and coverage recording files. But it's not covinient to use network file, many reasons. My question is, does clover support to read and write clover.db and coverage recording files throught ftp? Such as I can define the maven configure "clover.initstring=ftp://test:111111@hostname/projects/xxx/clover/clover.db".

If yes, how to configure it?

Hi Juan,

And what about writing coverage files on a local storage? There's a version of a coverage recorder which does not reqiure access to a Clover database. See this topic:

https://confluence.atlassian.com/display/CLOVER/Coverage+Recorders

This could simplify your deployment. Imagine a following scenario:

1. compile application with Clover using the Growable Coverage Recorder

you can do it by defining a <profile> in the <clover-setup> (in case of Ant), e.g.:

<clover-setup initstring="/build/server/path/to/clover.db"
  <profiles>
    <profile name="default" coverageRecorder="GROWABLE">
      <!-- <distributedCoverage/> optional -->
    </profile>
  </profiles>
  <!-- other options -->
</clover-setup>

A database will be created on your build server in a location specified by initstring.

2. run application with a fake path to coverage recorder

A growable recorder puts coverage data files in a directory where clover.db is located (no matter wheter the clover.db actually exists or not). So you can point to another location, e.g.:

java -cp ... -Dclover.initstring=/path/on/a/node/clover.db

I assume that all nodes in your system can write to the same location.

3. collect coverage data files

As soon as your tests are finished, copy coverage files from all nodes (using whatever tool available) back to your compilation server to a directory where the Clover database is present.

4. generate report

Create report(s) using the database and coverage files.
