From 532641ef30b0b095e8207563510e1454d5dca87d Mon Sep 17 00:00:00 2001 From: Ioannis Kakavas Date: Thu, 31 May 2018 18:09:32 +0300 Subject: [PATCH] Ensure intended key is selected in SamlAuthenticatorTests (#30993) * Ensure that a purposefully wrong key is used Uses a specific keypair for tests that require a purposefully wrong keypair instead of selecting one randomly from the same pull from which the correct one is selected. Entropy is low because of the small space and the same key can be randomly selected as both the correct one and the wrong one, causing the tests to fail. The purposefully wrong key is also used in testSigningKeyIsReloadedForEachRequest and needs to be cleaned up afterwards so the rest of the tests don't use that for signing.
