+Subject: [PATCH] python3-google-auth: Skip mTLS tests in ptest environment
+
+Mutual TLS tests require SSL certificates and proper crypto library
+setup that is not available in the isolated ptest environment.
+
+Skip all TestMutualTlsAdapter, TestMutualTlsOffloadAdapter, and
+TestMakeMutualTlsHttp tests as they require:
+- Valid SSL client certificates
+- Server certificates for mTLS handshake
+- Proper certificate chains and CAs
+
+These tests verify mTLS functionality which is not feasible to test
+in the embedded ptest runtime without external certificate infrastructure.
+
+Upstream-Status: Inappropriate [ptest environment limitation]

They need a cert infrastructure to execute. Mutual TLS authentication requires client/server certificates and a proper PKI setup that doesn't exist in the minimal qemu ptest environment. These are integration tests that need real certificate infrastructure.
