Hi,

We are using chromium as default browser for set-top-box.

We do some tests through python and webdriver , on remote host (not on set-to-box).

Previously (chromium version 53) it was working correctly.

We have recently rebased to chromium version 55.

It seems we have some issues since last update.

driver.get()on a url makes very long time .

Do you know if there are issues/incompatibilities with this chromium version and python webdriver.

Here are the versions we use:

chromedriver=2.24.417424, platform=Linux 3.13.0-109-generic x86_64

Thanks

Regards

Failure is the following :

logger.error( logs)

I think you better post this to chromedriver-users, or file an issue at crbug.com/chromedriver (if you could not find one).

Hi,

Thanks for your answer.

What i can say more precisely is that the problem seems linked to certificates.

I mean:

· If certificates are at the good area (which is the default), and I ask to change the url using python webdriver, it correctly works.

py.test --tb=short -s -rfx test_IWECertificates_new.py::test_https_url_with_certificates --junitxml=result.xml --html=result.html

------------- generated xml file: /local2/ljlevy/testNg/infinite-webengine/test/common/result.xml --------------

========================================== 1 passed in 102.14 seconds ==========================================

· If I do the same after having removed the certificates (tests expect to have an error) , there is a time latency (long more than 2 minutes)

py.test --tb=short -s -rfx test_IWECertificates_new.py::test_https_url_without_certificates --junitxml=result.xml --html=result.html

The behavior I was expected to have is to have an error when the certificated are not present , but not to get in timeout.

(This was the previous behavior of chromium version)

I give you some part of code:

def test_https_url_without_certificates(request,set_vars,prepare_test_environment,setup_certificates_env):

## Connect webdriver and start a view

assert(conftest.myConnection.isConnected())

# #############################

if (conftest.myConnection.isError()==True):

logger.error( logs)

assert False

# Mount bind an empty root certificate directory

logs = conftest.myConnection.runCommand(cmd='mount --bind /opt/empty_dir /etc/ssl/certs',mytimeout=conftest.SHORT_TIMEOUT)

print logs

if (conftest.myConnection.isError()==True):

logger.error( logs)

assert False

# Check certificates are no present

logs = conftest.myConnection.runCommand(cmd=conftest.getDbusEnvSetting()+' && ls /etc/ssl/certs/*.pem',mytimeout=conftest.LONG_TIMEOUT)

if (conftest.myConnection.isError()==False):

logger.error( logs)

assert False

output = ''.join(map(str, logs.encode('utf-8')))

assert 'Root_CA' not in output
