TestCast Professional brief overview

9


TestCast a TTCN-3 black-box test platform

10

► SUT can be any device or software component

► SUT input and output events are discrete

► SUT inputs must be controllable and outputs must be observable

► Black-box functional test checks SUT external behaviour conformance to the specified behavior

Test inputs

Observable outputs - functional test tool by Elvior- executes TTCN-3 scripted tests

System Under Test(SUT)


TestCast - supported operating systems

11

► Windows (32, 64 bit)

► .NET 3.5 or higher

► Linux (32, 64 bit)

► Mono 2.6.7 or higher

► Ubuntu

► Red Hat / Fedora

► OpenSUSESupported TTCN-3 versions

TTCN-3: 2003 … TTCN-3: 2011

TTCN3- test scripts1 Byte code2

► Elvior’s approach with TestCast


Full IDE for ease of use, also command line option

► Test Management, command line option, test session report, project viewer

14


TTCN-3 editor: go-to-definition, auto-complete, test suite viewer

22


TTCN-3 basics

23


What is TTCN-3?

► Testing and Test Control Notation Version 3

► TTCN-3 Testing Language

► Standardized modern high level language for testing

► TTCN-3 Architecture

► TTCN-3 TCI and TRI interfaces

► Black-box, functional testing of reactive systems

TTCN-3 in a nutshell (general environment)

TestC

ast


Central TTCN-3 concepts

►TTCN-3 is a language for testing

►Abstract data layer: data are not bound to any specific binary representation

►Dedicated commands for communication

►Dynamic and concurrent test configuration

►Automated test result evaluation

26


Test dedicated concepts in TTCN-3 (1/2)

► Data types

► Events

► Templates (send/receive)

► Matching mechanism

► Behavior trees (ALT {[]…}

► Altsteps

► Paralellel test components

► TRI, TCI

27


Test dedicated concepts in TTCN-3 (2/2)

►TTCN-3 has clear model how to structure your test

►With TTCN-3, test design will follow the same model

►TTCN-3 allows exchange of test suites among the players

28


TTCN-3 benefits compared other languages

► Why to use TTCN-3 for testing and not some other high level programming language (python, java)?

► Tracing and lookup facilities are provided by TTCN-3 tool (no programming needed)

► In TTCN-3 operational semantics is clearly defined

► Cost factors:► Coding effort

► Results analysis efforts

► Maintenance effort

► Debugging efforts

► Skill/training efforts

29


What type of coding effort is needed?

► Abstract Test Suite (ATS)

► Test dedicated language – coding effort reduced

► ATS concept makes test suite usable on different platforms and tools

► System Adapter (SA)

► TRI for C, C++, C#, Java mapping

30


TTCN-3 results analysis and debugging efforts

►When test was executed – how to know that the results are correct?

►TTCN-3 has built in verdict mechanism

►Tool offers means for analysis and tracing

►Tools have built-in debuggers (Elvior has a native TTCN-3 debugger)

31


TTCN-3 tests’ maintenance efforts

►Reduced maintenance effort, because of►Concept of test events (easier definition of test

functionality)

►Separation between abstract and concrete layers (TRI, TCI)

►Less code to look at given functionality

32


TTCN-3 skill/training efforts

► TTCN-3 is high level test dedicated programming language

► Syntax similar to C and Pascal

► Test dedicated concepts ands constructions

► Incremental study

► Basics – within 1 day

► Advanced – within 3 days

► Skills build up during the time

33


Brief summary of TTCN-3

TTCN-3 is preferred to use for testing than other general programming language

►It separates abstraction from implementation details.

►It includes test dedicated concepts► Templates

► Behavior tree

► Altsteps

► Snapshot mechanism

► Dedicated communication commands (send/receive)
