This standard is a multi-part deliverable covering PAdES digital signatures - Testing Conformance and Interoperability, as identified below: 
ETSI TR 119 144-1: "Overview"; 
ETSI TS 119 144-2: "Test suites for testing interoperability of PAdES baseline signatures"; 
ETSI TS 119 144-3: "Test suites for testing interoperability of additional PAdES signatures"; 
ETSI TS 119 144-4: "Testing Conformance of PAdES baseline signatures"; 
ETSI TS 119 144-5: "Testing Conformance of additional PAdES signatures". 

The multi-part deliverable defines test suites for testing interoperability and conformance of PAdES signatures.The test suites for testing interoperability of PAdES baseline signatures (Part 2) and the specifications required for building software tools for testing technical conformance of PAdES baseline signatures (Part 4) are defined against ETSI EN 319 142-1. The test suites for testing interoperability of additional PAdES signatures (Part 3) and the specifications required for building software tools for testing technical conformance of additional PAdES signatures (Part 5) are defined against ETSI EN 319 142-2.
