We can see that there are multiple testsuite results in it along with environment.xml.

I am trying to generate an allure report for it. Latest allurecommandline is installed.

When I try to run the following command, the allure report is empty.

allure generate allure-results/

It works when I give an individual result directory.

allure generate allure-results/assertions1

I am looking for a way to make allure generate a report based on all the testsuite results folders present in the allure-results.

The testsuite results are generated using python nosetests.
