OpenTTCN Tester for TTCN-3 is an interpreter-based concise, standard compliant, and easy to use TTCN-3 tool. Besides TTCN-3, the same tool also supports ASN.1 and TTCN-2. It offers no-frills implementation of TTCN-3 tester with affordable price from a company that has the longest background from TTCN execution tools.

OpenTTCN Tester for TTCN-3 consists of two parts:

1. OpenTTCN Tester: tool that executes TTCN-3 and TTCN-2 test cases:
   • virtual machine, interpreter-based, easy and simple to use,
   • efficient: test execution done in C++ based component, and
   • easy to integrate with any existing test management systems, etc.
2. OpenTTCN SDK: ANSI C libraries to implement SUT and platform adapters and integrate with existing user interfaces/test management software; consists of:
   • TRI API: ETSI ES 201 873-5: SUT adapters and Platform adapters,
   • TCI-CD API: ETSI ES 201 873-6: coding and decoding support, and
   • TCI-TM API: ETSI ES 201 873-6: test management applications.

OpenTTCN Tester and SDK packages are downloaded using username and password from:

http://www.openttcn.com/updates

During your evaluation or warranty period or when you have a software maintenance contract in effect, you can download all the updates from the above location as well.

From the above location you might want to download:

1. OpenTTCN Tester installation package: OpenTTCN-tester-2.56.0.exe,
2. OpenTTCN SDK installation package: OpenTTCN-sdk-2.56.0.exe, and
3. OpenTTCN license key: OpenTTCN.lic.

Before installation, please check that you have:

1. Windows XP, or Windows 2000 operating system (if you have something else, please contact us),
2. 100 MB free disk space for OpenTTCN Tester,
3. 200 MB free disk space for OpenTTCN SDK,
4. if you compile examples, a Microsoft Visual Studio 2005 (8.0) compiler is needed,
5. Java JRE or JDK installed in your system before installing OpenTTCN, version 1.5 Update 9 is recommended, but 1.3.1 or 1.4.2 will suffice. If you do not have one, you can get and install one from:

   http://java.sun.com/j2se/

Note 1: OpenTTCN uses Java only for parsing TTCN-3 specifications, not during actual test execution operations.

Note 2: If you just use TTCN-2, you DO NOT NEED to install Java JRE as it is only used by TTCN-3 parser.

1. Run OpenTTCN-tester-2.56.0.exe installation program and accept default choices, for example, for installation location.
2. Copy license key file, OpenTTCN.lic, to c:\Program Files\OpenTTCN\Tester3\etc.
3. You are done.

• Activate OpenTTCN Tester for TTCN-3
• You can activate your OpenTTCN Tester from the command prompt with the command "ot activate". For more information about the activation, please refer to the Support-pages and the OpenTTCN Tester for TTCN-3 installation tutorial.

• Read the README for information about the OpenTTCN Tester.
• You can find README from the Windows "Start" menu: In XP: Start > All Programs > OpenTTCN Tester for TTCN-3 > OpenTTCN Tester README
• It can also be found at: c:\Program Files\OpenTTCN\Tester3\README.pdf

• There is a TTCN-3 example in the c:\Program Files\OpenTTCN\Tester3\testing\Demo3 directory, and
• Instructions for the example: c:\Program Files\OpenTTCN\Tester3\testing\Demo3\demoTTCN3.pdf document.

• There is a TTCN-2 example in the c:\Program Files\OpenTTCN\Tester3\testing\Demo2 directory, and
• Instructions for the example: c:\Program Files\OpenTTCN\Tester3\testing\Demo2\demoTTCN2.pdf document.

1. Run OpenTTCN-sdk-2.56.0.exe installation program and accept default choices, for example, for installation location. This lets you compile examples without modifying the project files.
2. You are done.

• Read the README for information about content of the SDK and how to locate the examples of the SDK.
• You can find README from the Windows "Start" menu: In XP: Start -> All Programs -> OpenTTCN SDK -> OpenTTCN SDK README
• One of these examples shows how to implement a SUT adapter, a platform adapter, and a coding and decoding adapter. The other example shows how to control tester through the TCI-TM interface.

Current stable version of OpenTTCN Tester for TTCN-3 is 2.56.0.

We are currently 1) automating the TTCN-3 adapter start-up, 2) implementing a separate tool that translates TTCN-2 test suites to TTCN-3, and 3) adding a fine-grained logging interface to TCI-TM that will benefit test system vendors that are interested in adding more capabilities to their log handling.
