+    When validating a password, Synapse does the necessary checks in this order:
+
+        1. Password is long enough
+        2. Password contains digit(s)
+        3. Password contains symbol(s)
+        4. Password contains uppercase letter(s)
+        5. Password contains lowercase letter(s)
+
+    For each test below that checks whether a password triggers the right error code,
+    that test provides a password good enough to pass the previous tests, but not the
+    one it is currently testing (nor any test that comes afterward).
