adding metadata to testdroid's junit xml

Question

When running Android Instrumentation tests with TestDroid, it outputs JUnit XML. e.g.,

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<testsuites>
  <testsuite errors="0" failures="1" hostname="Acer Iconia Tab A1-810 - YSF6Y9HE6SQCOJPV" name="ExampleInstrumentedTest" package="com.myco.androidtest" tests="2" time="0.0000" timestamp="Fri Sep 29 21:29:49 CEST 2017">
    <testcase classname="com.myco.androidtest.ExampleInstrumentedTest" name="someTest" time="0.0000"/>
    <testcase classname="com.myco.androidtest.ExampleInstrumentedTest" name="someOtherTest" time="0.0000">
      <failure message="" type="">java.lang.AssertionError&#13;
        at org.junit.Assert.fail(Assert.java:86)&#13;
        ...
      </failure>
    </testcase>
  </testsuite>
  <properties>
    ...
    <property name="ro.product.manufacturer" value="Acer"/>
    <property name="ro.serialno" value="32206769320"/>
    <property name="ro.product.name" value="a1-810_ww_gen1"/>
    <property name="ro.build.version.release" value="4.2.2"/>
    <property name="ro.build.version.sdk" value="17"/>
    <property name="ro.build.fingerprint" value="acer/a1-810_ww_gen1/mango:4.2.2/JDQ39/1381313631:user/release-keys"/>
    <property name="ro.product.cpu.abi" value="armeabi-v7a"/>
    <property name="ro.product.model" value="A1-810"/>
  </properties>
</testsuites>

In addition to metadata about the tests, it seems like they're dumping Java system properties into the xml, which is pretty useful.

I'd like to add to the metadata/properties in the JUnit XML. Any ideas on how that can be done?

It's done based on ddmlib functionalities. You should use com.android.ddmlib.testrunner.RemoteAndroidTestRunner passing proper com.android.ddmlib.IDevice and your implementation of com.android.ddmlib.testrunner.ITestRunListener (which should be responsible for collecting test info and generating junit xml) to run method, once test is finished you can generate xml and dump to file, adding com.android.ddmlib.IDevice#getProperties at the end.
