Question

I have system of:

• svn – control version
• cc.net – as ci server
• msbuild – as a build system
• nunit – for launch test
• webdriver – for web-testing.

Now my tests are run automatically after each commit. But i want that my test run if commit has comment #runautotest (or another).

I investigated triggers of cc.net but its are for another goals.
I try to found some information about cc.net parse logs but this was don’t has positive result.

What kind of ways i should use for resolve my issue?

Answer 1

In the ccnet config, in the project, at the top of the tasks block:

<modificationWriter>
 <filename>svn_mods.xml</filename>
 <path>c:\modsdir</path>
</modificationWriter>

This will write the SVN modifications to a file.

Next in the tasks block:

<nant>
 <executable>c:\path_to_nant</executable>
 <buildFile>mybuildfile.build</buildFile>
 <targetList>
  <target>conditionally_run_nunit_tests</target>
 </targetList>
</nant>

This will run a Nant task after the modificationwriter task.

In conditionally_run_nunit_tests, search the file c:\modsdir\svn_mods.xml for #runautotest. If you find it, run the tests. If you don’t find it then do nothing. There are various ways to parse the mods file. You could use C# script to read the entire file into a string and then call Contains passing in #runautotest.

The below code is an example of using C# script in Nant. SearchFile opens a file, reads it into a string and checks if a value is in the string. It returns “yes” or “no”. The below script is untested.

<property name="yesno" value="${ns::SearchFile("c:\modsdir\svn_mods.xml", "#runautotest")}"/>

<script language="c#" prefix="ns">

        string myString = myFile.ReadToEnd();
        myFile.Close();
        if(myString.Contains(token)) return "yes";
        else return "no";
    }
