Problems with “Aggregate downstream test results” in Hudson

Question

My Hudson projects don\'t seem to properly aggregate downstream test results and I\'m wondering if I\'ve missed a configuration step somewhere. I have two projects, Foo and Foo-

I was able to replicate your problem with Hudson 1.266. This a Hudson error, which was fixed in a later build (prior to 1.287), so either upgrade Hudson or use this two-click workaround: from the Project page, go first to Latest Build and then Aggregated Test Results.

The problem is that the Project page for Foo is only showing the Latest Test Results link, which has a URL like http://localhost:8080/hudson-1.266/job/Foo/lastBuild/testReport/. Since Foo has no tests of its own, this link has no JUnit XML file to reference and returns the error you mentioned. This was fixed somewhere between 1.266 and 1.287 by redirecting from latestBuild/testReport/ back up to latestBuild/ when there are no tests. The alternative for you in 1.266 is to, instead of clicking on Latest Test Results in the Project page, scroll down a bit and click on Latest Build under Permalinks. This will take you to the latestBuild/ URL, and from there you can click on Aggregated Test Result, which has a URL like http://localhost:8080/hudson-1.266/job/Foo/lastBuild/aggregatedTestReport/. On this page, all your test results from downstream projects will be available under the Drill Down section.

Unfortunately, there is still a problem with the Drill Down links, even in 1.287. From Foo, when you drill down to Foo-Tests as outlined above, you will be taken to a malformed URL, which looks like http://localhost:8080/hudson-1.287job/Foo-Tests/. You'll have to manually modify that URL to insert a / between the hudson context and the job path following it so that it looks like http://localhost:8080/hudson-1.287/job/Foo-Tests/. Then you will be able to actually see the downstream test results.

I haven't had a chance to look through the Hudson source to find the error, but there's already an issue open for this. Its issue 1574, and its been open for almost a year.

On a side note, I really love Hudson for CI, but their interface isn't as smooth as it could be. I look forward to their rework of the UI in ExtJS. Maybe thats what they're spending all their time on.
