Programmatically Gathering NUnit results

I am running some NUnit tests automatically when my nightly build completes. I have a console application which detects the new build, and then copies the built MSI's to a local folder, and deploys all of my components to a test server. Af开发者_运维问答ter that, I have a bunch of tests in NUnit dll's that I run by executing "nunit-console.exe" using Process/ProcessStartInfo. My question is, how can programmatically I get the numbers for Total Success/Failed tests?

Did you consider using a continous integration server like CruiseControl.NET?

It builds and runs the tests for you and displays the results in a web page. If you just want a tool, let the nunit-console.exe output the results in XML and parse/transform it with an XSLT script like the ones coming from cruise control.

Here is an example of such an XSL file if you run the transformation on the direct output of nunit-console.exe then you will have to adapt the select statements and remove cruisecontrol.

However it sounds like you might be interested in continuous integration.

We had a similar requirement and what we did was to read into the Test Result XML file that is generated by NUnit.

XmlDocument testresultxmldoc = new XmlDocument();
testresultxmldoc.Load(this.nunitresultxmlfile);

XmlNode mainresultnode = testresultxmldoc.SelectSingleNode("test-results");
this.MachineName = mainresultnode.SelectSingleNode("environment").Attributes["machine-name"].Value;
int ignoredtests = Convert.ToInt16(mainresultnode.Attributes["ignored"].Value);
int errors = Convert.ToInt16(mainresultnode.Attributes["errors"].Value);
int failures = Convert.ToInt16(mainresultnode.Attributes["failures"].Value);
int totaltests = Convert.ToInt16(mainresultnode.Attributes["total"].Value);
int invalidtests = Convert.ToInt16(mainresultnode.Attributes["invalid"].Value);
int inconclusivetests = Convert.ToInt16(mainresultnode.Attributes["inconclusive"].Value);

We recently had a similar requirement, and wrote a small open source library to combine the results files into one aggregate set of results (as if you had run all of the tests with a single run of nunit-console).

You can find it at https://github.com/15below/NUnitMerger

I'll quote from the release notes for nunit 2.4.3:

The console runner now uses negative return codes for errors encountered in trying to run the test. Failures or errors in the test themselves give a positive return code equal to the number of such failures or errors.

(emphasis mine). The implication here is that, as is usual in bash, a return of 0 indicates success, and non-zero indicates failure or error (as above).
