Question

I've done a build.xml un the root of my drupal 8 path, and when i run ./vendor/bin/phing on my phpunit test in orther to convert the xml log to html, i don't have expected result. So how can i modify my build.xml

my build.xml

<project name="svie_tarificateur_report" default="spheria-report" basedir=".">
    <!--<taskdef name="myecho" classname="MyEchoTask" />-->
 <target name="spheria-report">
     <echo msg="Hello, Doric!" />
     <autoloader autoloaderpath="./autoload.php"/>
  <phpunitreport infile="log.junit.xml"
                 format="frames"
                 todir="html"
                 styledir="/usr/share/php/data/phing/etc/"
                 />
 </target>
</project>

my phpunit log

<?xml version="1.0" encoding="UTF-8"?>
<testsuites>
  <testsuite name="modules/custom" tests="2" assertions="2" errors="0" failures="0" skipped="0" time="0.008327">

If you are using Composer then the autoload.php file is located inside vendor dir, try something like this:

<autoloader autoloaderpath="vendor/autoload.php"/>
