+// Tests that end-entity certificates that should successfully verify as EV
+// (Extended Validation) do so and that end-entity certificates that should not
+// successfully verify as EV do not. Also tests related situations (e.g. that
+// failure to fetch an OCSP response results in no EV treatment).
+//
+// A quick note about the certificates in these tests: generally, an EV
+// certificate chain will have an end-entity with a specific policy OID followed
+// by an intermediate with the anyPolicy OID chaining to a root with no policy
+// OID (since it's a trust anchor, it can be omitted). In these tests, the
+// specific policy OID is 1.3.6.1.4.1.13769.666.666.666.1.500.9.1 and is
+// referred to as the test OID. In order to reflect what will commonly be
+// encountered, the end-entity of any given test path will have the test OID
+// unless otherwise specified in the name of the test path. Similarly, the
+// intermediate will have the anyPolicy OID, again unless otherwise specified.
+// For example, for the path where the end-entity does not have an OCSP URI
+// (referred to as "no-ocsp-ee-path-{ee,int}", the end-entity has the test OID
+// whereas the intermediate has the anyPolicy OID.
+// For another example, for the test OID path ("test-oid-path-{ee,int}"), both
+// the end-entity and the intermediate have the test OID.
