Bamboo is not killing job while pytest script is completed successfully

[Vipin Kumar]

My task is configured in bamboo like with 3 lines:

<pytest script>

Echo $?

exit 0

Now execution output observed as:

/nfs/tools/dtd/dtd_production_linux/swtools/6500/python/testsuite/py3_openroadm/netconf.py:83: Failed
 generated xml file: /localdata/bamboo-agent-home/xml-data/build-dir/NBI-OWB21255-OS/testresult1.xml -
============= 2 failed, 42 passed, 12 warnings in 1333.56 seconds ============

 1  --> this is echo $? output.

But Bamboo continue to run the same job. Ideally it should stop.
