Specify a trust store that'll be used for HTTPS requests. A trust store is a {@link java.security.KeyStore} that has been loaded with the password.
If you wish that REST Assured loads the KeyStore store and applies the password (thus making it a trust store) please see some of the
<code>keystore</code> methods such as {@link #keyStore(java.io.File, String)}.

@param truststore A pre-loaded {@link java.security.KeyStore}.
@see #keyStore(String, String)
