We can generate the details of the test execution in an xml file. This xml file is mainly useful in cases where we have a dashboard that projects the test results. In such cases, the xml can be parsed to get the details of the execution.

We will now execute the tests from test_multiplcation.py and generate the xml by running

pytest test_multiplication.py -v --junitxml="result.xml"

Now we can see result.xml is generated with the following data −

<?xml version = "1.0" encoding = "utf-8"?>
<testsuite errors = "0" failures = "1"
name = "pytest" skips = "0" tests = "4" time = "0.061">

Here, the tag <testsuit> summarises there were 4 tests and the number of failures are
1.

• The tag <testcase> gives the details of each executed test.

• <failure> tag gives the details of the failed test code.
