"""Gathers output from test runs and create an XML file in JUnit format.
|
|
The output files from the individual tests have been written in a directory
|
structure like:
|
|
$DIR/joblog (output from "parallel --joblog joblog")
|
$DIR/logs/1/cpp/stdout
|
$DIR/logs/1/cpp/stderr
|
$DIR/logs/1/csharp/stdout
|
$DIR/logs/1/csharp/stderr
|
$DIR/logs/1/java_jdk7/stdout
|
$DIR/logs/1/java_jdk7/stderr
|
etc.
|
|
This script bundles them into a single output XML file so Jenkins can show
|
detailed test results. It runs as the last step before the Jenkins build
|
finishes.
