Test Execution Results in Pytest XML Format

We can generate test execution details in an XML file. This XML file is primarily useful when we have a dashboard that provides predictive test results. In this case, the XML can be parsed to obtain the execution details.

Now we’ll execute the tests in test_multiplication.py and generate the XML file by running:

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

Now we can see that result.xml is generated using the following data:

<?xml version = "1.0" encoding = "utf-8"?>
<testsuite errors = "0" failures = "1"
name = "pytest" skips = "0" tests = "4" time = "0.061">
   <testcase classname = "test_multiplication"
      file = "test_multiplication.py"
      line = "2" name = "test_multiplication_11[1-11]"
      time = "0.00117516517639>
   </testcase>

   <testcase classname = "test_multiplication"
      file = "test_multiplication.py"
      line = "2" name = "test_multiplication_11[2-22]"
      time = "0.00155973434448">
   </testcase>

   <testcase classname = "test_multiplication"
      file = "test_multiplication.py"
      line = "2" name = "test_multiplication_11[3-35]" time = "0.00144290924072">
      failure message = "assert (11 * 3) == 35">num = 3, output = 35

         @pytest.mark.parametrize("num,
         output",[(1,11),(2,22),(3,35),(4,44)])

         def test_multiplication_11(num, output):>
         assert 11*num == output
         E assert (11 * 3) == 35

         test_multiplication.py:5: AssertionError
      </failure>
   </testcase>
   <testcase classname = "test_multiplication"

</testcase>

</testsuite>

Here, the tag **** summarizes that there are 4 tests and the number of failures is 1.

• The tag **** gives details about each test executed.

• The

  <failure> tag gives details about the test code that failed.
