 The purpose of this API is to allow the re-use of the Test Port class with other port types marked with attribute `user` or with ports with translation capability (link:https://www.etsi.org/deliver/etsi_es/202700_202799/202781/01.04.01_60/es_202781v010401p.pdf[Methods for Testing and Specification (MTS); The Testing and Test Control Notation version 3; TTCN-3 Language Extensions: Configuration and Deployment Support]). The user port types may have different lists of incoming and outgoing message types. The transformations between incoming and outgoing messages, which are specified entirely by the attribute of the user port type, are done independently of the Test Port. The Test Port needs to support the sending and reception of message types that are listed in the provider port type.

 To make it easier to use the encoding features, a unified common API was developed. With help of this API the behaviour of the test executor in different error situations can be set during coding. There is also a common buffer class. The details of the above mentioned API as well as the specific features of the certain encoders are explained in the following sections.

 The purpose of this API is to allow the re-use of the Test Port class with other port types marked with attribute `user` or with ports with translation capability (link:https://www.etsi.org/deliver/etsi_es/202700_202799/202781/01.04.01_60/es_202781v010401p.pdf[Methods for Testing and Specification (MTS); The Testing and Test Control Notation version 3; TTCN-3 Language Extensions: Configuration and Deployment Support]). The user port types may have different lists of incoming and outgoing message types. The transformations between incoming and outgoing messages, which are specified entirely by the attribute of the user port type, are done independently of the Test Port. The Test Port needs to support the sending and reception of message types that are listed in the provider port type.
