uftrace for TTCN3
TTCN-3 (Testing and Test Control Notation version 3) is a testing language used in conformance testing of communicating systems.
TTCN-3 has been used to define conformance test suites.
- The Open Mobile Alliance adopted in 2008 a strategy of using TTCN-3 for translating some of the test cases in an enabler test specification into an executable representation.
- The AUTOSAR project promoted (2008) the use of TTCN-3 within the automotive industry.
- The 3GPP project promoted the use of TTCN-3 within the mobile industry.
We can install TTCN3 Toolset eclipse-titan.
$ sudo apt install eclipse-titan
Take the source code for intel's net-test-suites for TTCN-3, and do uftrace tracing.
$ git clone https://github.com/intel/net-test-suites.git
Building TTCN-3 sequence is .ttcn -> .cc -> Executable binary.
We need to add -pg options.

We can use also Perfetto with dumped json file.
# alias uftrace_json="$HOME/uftrace/uftrace dump --libmcount-path=$HOME/uftrace --chrome > dump.json"
$ uftrace_json
Upload dumped json file from Open trace file button.
We can use shortcut for trace2html.
# alias uftrace_dump="( $HOME/uftrace/uftrace dump --libmcount-path=$HOME/uftrace --chrome > dump.json ) && ( $HOME/catapult/tracing/bin/trace2html dump.json )"
