Troubleshooting CruiseControl.Net and Completed Unit Tests

CruiseControl.Net Update

So, I explained yesterday how I got CruiseControl.Net installed as part of my quest to institute Continuous Integration in my development project. After I published yesterday's entry, I found that I hadn't done one crucial thing.

Getting The Latest  Version From Subversion Before The Build

My build kept happening every time I "committed" a new version of a source file to Subversion, but my changes weren't showing up in the CruiseControl.Net build. I soon realized my mistake, I needed to modify the the NAnt build files with a couple of new <target>'s, one for getting the latest version from source control, and one for calling the "update" target and then the "build" target. I could have just added the "update" to the "build" target, but I may want to just "build" the current snapshot rather than always getting the latest version. So now I have the following for my main (D:\VirtualCellar\default.build) file. I found this page helpful in setting up CruiseControl.Net with Subversion.

<?xml version="1.0"?>
<project name="VirtualCellar" default="build" basedir=".">
  <property name="debug" value="true"/>
  <property name="build.deploy" value="release"/>
  <property name="build.business" value="Lorengo.VirtualCellar.Business"/>
  <property name="build.business.tests" value="Lorengo.VirtualCellar.Business.Tests"/>

  <sysinfo/> 

  <target name="build" description="compiles projects">
    <nant buildfile="${build.business}/default.build" target="build"/>
    <nant buildfile="${build.business.tests}/default.build" target="build"/>

    <copy todir="${build.deploy}/bin" file="${build.business}/bin/debug/${build.business}.dll"/>
  </target>

  <target name="update" description="Gets the latest version from source control">
    <exec basedir="." program="d:\program files\subversion\bin\svn.exe" commandline="update" />
  </target>

  <target name="buildLatest" description="Builds the latest version from source control" depends="update,build" />
</project>

The "buildLatest" target depends the "build" target which depends on the "update" target. This is backwards, according to the documentation according to the documentation it should be depends="build,update", but it works for me.

You'll notice that I've added an <exec> task to get the latest version from source control. This gets the latest version for the basedir and all child folders. I also updated my other default.build files for the other projects to do this step should I wish to only build a project.

So, I check commit these to Subversion and it fixes my problem right? Wrong! Because the existing default.build files in the d:\build\VirtualCellar folder don't have the new <target>s so the update never happens, I need to manually type the "svn update" command in the d:\build\VirtualCellar folder to bring down the latest version. In addition I also need to update the d:\program files\CruiseControl.Net\Server\ccnet.config file to build the new "buildLatest" target. Here's the updated ccnet.config file.

<cruisecontrol>
  <project name="VirtualCellar">
    <webURL>http://localhost/ccnet</webURL>
    <schedule type="schedule" sleepSeconds="300"/>
    <sourcecontrol type="svn">
      <executable>D:\program files\subversion\bin\svn.exe</executable>
      <trunkUrl>file:///D:/Svn/VirtualCellar/trunk</trunkUrl>
    </sourcecontrol>
    <build type="nant">
      <executable>D:\Program Files\nant-0.84\bin\nant.exe</executable>
      <baseDirectory>D:\Build\VirtualCellar</baseDirectory>
      <buildFile>default.build</buildFile>
      <buildargs></buildargs>
      <targetList>
        <target>buildLatest</target>
      </targetList>
      <buildTimeoutSeconds>300</buildTimeoutSeconds>
    </build>
    <publishers>
      <xmllogger>
        <logDir>..\web\log</logDir>
      </xmllogger>
    </publishers>
  </project>
</cruisecontrol>

In addition to the change in the <target> node, you'll see that I've added a <publishers> node that contains an entry for a log directory. This is where the resulting build log will get created. I made a d:\program files\cruisecontrol.net\web\log folder and pointed the logdir there.

Setting up the Web

I went and setup a Virtual Directory in IIS to point to the d:\program files\cruisecontrol.net\web folder and named it CCNET, so now when I go to http://localhost/ccnet, I get a screen like this

You can see here that it took me a few tries to get the build to successfully get the latest version from source control. This entry shows that the last build was successful, and it's been an hour since it's done another build. Remember it checks to see if there are any changes, and builds if there are any.

Unit Tests for First User Story Complete

I've completed my first set of Test Cases for my first User Story. All of them pass!

I've ended up with the following two classes (Cellar & Wine). I'm satisfied with the current implementation for the first user story, but I can already see problems with this implementation. I need to switch focus to the Wine class and devote some modeling time to my project. In particular how Wine objects come into being. I think there's a WineCatalog or somesuch class in my future that will hold all of the known wines. So that's what I'll be working on today and hopefully publish my intial model tomorrow!.
