Unable to get testname while calling pytest execution from python or subprocess - pytest

Question

I am trying to create test runner python file, that executes the pytest.exe in particular testcase folder and send the results via email.
Here is my code:
test_runner.py:
try:
command = "pytest.exe {app} > {log}".format(app=app_folder, log = log_name)
os.system(command)
except:
send_mail()
I use the following code in conftest.py to add screenshots to pytest-html report.
In conftest.py:
#pytest.mark.hookwrapper
def pytest_runtest_makereport(item, call):
pytest_html = item.config.pluginmanager.getplugin('html')
outcome = yield
report = outcome.get_result()
extra = getattr(report, 'extra', [])
if pytest_html:
xfail = hasattr(report, 'wasxfail')
if (report.skipped and xfail) or (report.failed and not xfail):
test_case = str(item._testcase).strip(")")
function_name = test_case.split(" ")[0]
file_and_class_name = ((test_case.split(" ")[1]).split("."))[-2:]
file_name = ".".join(file_and_class_name) + "." + function_name
Issue is, when I run the command "pytest.exe app_folder" in windows command prompt it is able to discover the test cases and execute them and get the results. But when I call the command from .py file either using os.command or subprocess it fails with the following exception:
\conftest.py", line 85, in pytest_runtest_makereport
INTERNALERROR> test_case = str(item._testcase).strip(")")
INTERNALERROR> AttributeError: 'TestCaseFunction' object has no attribute
'_testcase'
Can anyone please help me to understand whats happening here? or any other way to get the testcase name?
Update:
To overcome this issue, I alternatively used the TestResult object from pytest_runtest_makereport hook to get the test case details.
#pytest.mark.hookwrapper
def pytest_runtest_makereport(item, call):
outcome = yield
report = outcome.get_result()
In the above example, report variable contain the TestResult object. This can be manipulated to get the testcase/class/module name.

Answer 1

you can use shell=True option with subprocess to get the desired result
from subprocess import Popen
command='pytest.exe app_folder' #you can paste whole command which you run in cmd
p1=Popen(command,shell=True)
This would solve your purpose
