Test timings can't be found

Alright, we actually found the issue from the JUnit report that Cucumber generated by default. As we can see from the doc here the XML as following:

<?xml version="1.0" encoding="UTF-8"?>
<testsuite failures="0" errors="0" skipped="2" tests="2" time="0.05" name="Pending step">
  <testcase classname="Pending step" name="Pending" time="0.05">
    <skipped/>
      <system-out/>
    <system-err/>
  </testcase>
  <testcase classname="Pending step" name="Undefined" time="0.05">
    <skipped/>
    <system-out/>
    <system-err/>
  </testcase>
    <system-out>
      <![CDATA[]]>
    </system-out>
    <system-err>
      <![CDATA[]]>
    </system-err>
</testsuite> 

Using the validator that I mention in the previous comment. We found that some of the tags causing this issue on the circle-ci such as <![CDATA[]]> , <system-out/> , etc.

So we created custom JUnit that makes CircleCI happy about and it works. For the reference of how the XML format should be, please see this StackOverflow threads something like this:

<testsuites>
  <testsuite>
    <properties>
      <property> ... </property>
    </properties>

    <testcase> ... </testcase>
  </testsuite>
</testsuites>

Hope this can be helpful for those have similar issue like us.
