+Subject: [PATCH] make the TLS tests skip when pyopenssl isn't available
+
+In some distributions e.g. yocto
+pyOpenSSL is a packageconfig and disabled by default,
+and it means pyopenssl.py module is not installed as a result.
+
+This test fails plainly when it can not find urllib3.contrib.pyopenssl
+instead skip the test if it does not find the module.
+
+Upstream-Status: Submitted [https://github.com/googleapis/google-auth-library-python/pull/1873]
