Function TestPingFail

client/ping_test.go:19–46

TestPingFail tests that when a server sends a non-successful response that we can still grab API details, when set. Some of this is just exercising the code paths to make sure there are no panics.

// Some of this is just exercising the code paths to make sure there are no
// panics.

// TestPingWithError tests the case where there is a protocol error in the ping.
// This test is mostly just testing that there are no panics in this code path.
