error writing to output directory

[Raymond Camden]

I'm seeing this in my console:

[mxunittask] [mxunit error] Error trying to write to : testresults.
Please make sure this output dircetory exists.

But what I don't get is why. I've defined the following:

<property name="output.dir" value="c:\testresults" />

and then here is my mxunit tags...

<target name="runUnitTests" >
<mkdir dir="${output.dir}" />
<echo message="Creating ${output.dir}" />
<taskdef name="mxunittask" classname="org.mxunit.ant.MXUnitAntTask"
classpath="mxunit-ant.jar" />
<mxunittask server="the server..." port="80" defaultrunner="$
{test.runner}" outputdir="${output.dir}" verbose="true">
<directory path="${test.dir.location}" recurse="true"
componentPath="stuff.unittests" />
</mxunittask>
</target>

When run I clearly see my output directory being created. I also tried
modifying <echo> to write to a file within the directory. That worked
too. But mxunit seems unable to write to the folder.

Ray,

Could you run your Ant script with -v (-verbose) option and post the
stacktrace?

thx,
bill

[Raymond Camden]

Sure - but I'm removing a bit for privacy sake. Note - there is an error _after_ the dir error about site certificates. I'm not so worried about that yet. But if _that_ error is the root cause and the first error is just a side effect, then let me know.

Ray,

It looks like the cert error may be the root cause. You should be
seeing an http status code immediately following "[mxunittask] Running
http ...."; e.g., 200, 500, etc. But an IOException is being caught
instead at that point. The task is trying to read data from the http
inputstream, which doesn't exist, perhaps, because the http client is
not ignoring the cert. Can you fix the cert or somehow bypass it?
(I'll also look to see how we might be able to ignore that with
HttpClient)

Any suggestions on how to get Ant to trust the ssl cert being used by the remote site?

You can add it to the default certificate store... basically the same
routine you go through to get CF to trust a self-signed cert.

As far as I know, there's no simple "set this system property:
trust=true" type of deal, but that doesn't mean there isn't one. =)

There's also some code changes that could be done to use a "trust
everything" SSL context, but that would only be cool if you could turn
it on and off, I reckon.

No luck so far. Tried importing the site certificate using keytool and it report sok - but running the ant task again gives me the exact same issue.

[Marc Esher]

Is it the same both inside and outside of eclipse?

Ray,

Looks like the cert is self signed, true?

[Raymond Camden]

I'm doing this 100% through command line right now.

Yes. This is just for internal testing only. No need for anything to
work outside of our network.

[bill shelton]

Ray,

 

This will require an enhancement to the MXUnit Ant task so that it will accept self-signed or untrusted SSL certificates.  The good news is that HttpClient 3.x provides an EasySSLProtocolSocketFactory class that may work. I'll look into it today to see what's involved. Of course, if anyone is interested in picking this up and running with it, I assure you that you will get no push-back whatsoever  ;-)

 

best,

bill

[bill shelton]

Ray,

 

Working on this today ... can you try one thing? It's a shot in the dark, but I'd like to rule it out. Change your build file to the following:

 

<mxunittask

   server="the server..."
   connectionMethod="https"
   port="443"

   defaultrunner="${test.runner}"
   outputdir="${output.dir}"
   verbose="true">
 
  <directory path="${test.dir.location}"
             recurse="true"
             componentPath="stuff.unittests"  />
 </mxunittask>

 

bill

 

 

 

[bill shelton]

[bill shelton]

Ray,

 

Try this newer build:  http://mxunit.googlecode.com/svn/org.mxunit.ant.idea/trunk/dist/mxunit-ant.jar

 

Make sure to add the connectionMethod="https" and the SSL port; e.g., port="443".

[Raymond Camden]

Woot! We have a winner. Thank you VERY much!

[bill shelton]

Glad it worked, Ray. I'll do a little more clean up and commit to the MXUnit trunk and update the docs.

For those interested, the issue was due to a self signed certificate which the Ant task did not handle. The result was a fatal SSL handshake.  Since we use Apache HttpClient 3.x under the hood, we needed to set the SSLContext such that it accepts a "naive" TrustManager; in other words, a TrustManager that trusts all certificates. Obviously, this is not a good practice to do with production HTTP clients and servers, but for automated test builds in a non-production environment it's probably acceptable. (Comments or suggestions are welcome)

Further info: RFC 5246, TLS Protocol: http://tools.ietf.org/html/rfc5246 . Section 7.2.2, Error Alerts, explains some of the handshake contract.

[Marc Esher]

Great job, Bill. Thanks for the explanation, too.

marc

[bill shelton]

This fix has been committed to the mxunit framework trunk and is available for general distribution via SVN and github.

One minor note is that you should use protocol instead of connectionMethod to specifiy http or https.  protocol seems clearer and is now documented on the wiki (though both attributes are semantically equivalent and both will work).
