I have a Java project, which consists of loads of maven modules and a considerable amount of unit/integration tests. The project is configured to create test reports via the surefire plugin. Now this plugin basically creates an XML-report per test class and is scheduled to run once a day and executed on Jenkins.
What I want to do is, send the those XML-reports to a test management system (XRAY) in order to make them more visible and manageable. My (naive) approach would be to just just add a post build script on Jenkins and send those reports via curl to the test managements REST-API. This API offers a way to send a single report file at a time. This report file can either be single or nested, i.e. I can basically send both of the following and it works:
Single report
<testsuite>
...
</testsuite>
Aggregated report
<testsuites>
<testsuite ... />
<testsuite ... />
</testsuites>
The REST-API can handle both, that is the IBM JUnit schema and the standard surefire schema
Now to the problem; I obviously want to combine those reports into one to avoid having to make a billion requests to the REST-API. However I can't seem to find an automated way. What I've tried so far is
The only other way I can think of is to write a "merge script" myself, possibly using some sort of XSLT-transformation. But I'd rather not. Any help is much appreciated, thanks!
The solution would be to use an external utility for that as surefire seems to not support it. I've used successfully junit-merge utility, which is an NPM package, as you can see for example in this tutorial. The usage is pretty straightforward; you just need to specify the output file and the input folder containing the multiple JUnit XML based reports.
junit-merge -o results.xml -d target/surefire-reports/
