Example

Content of test_junit.py:

def test_stdout():
    print('Testing...')

Let's run the test: pytest test_junit.py -v --junitxml result.xml

Content of result.xml:

<?xml version="1.0" encoding="UTF-8"?>
<testsuites>
   <testsuite errors="0" failures="0" hostname="likai-ubuntu" name="pytest" skipped="0" tests="1" time="0.010" timestamp="2020-03-20T19:11:11.630551">
      <testcase classname="capture.test_junit" file="capture/test_junit.py" line="0" name="test_capture" time="0.000" />
   </testsuite>
</testsuites>

If I run the same test with pytest 5.3.5, the result contains stdout:

<?xml version="1.0" encoding="UTF-8"?>
<testsuites>
   <testsuite errors="0" failures="0" hostname="likai-ubuntu" name="pytest" skipped="0" tests="1" time="0.011" timestamp="2020-03-20T19:17:00.902714">
      <testcase classname="capture.test_junit" file="capture/test_junit.py" line="0" name="test_capture" time="0.000">
         <system-out>Testing...</system-out>
      </testcase>
   </testsuite>
</testsuites>
