Run Rational Functional Tester on Linux

Most of Functional Tester features are supported on Linux , except for recording the scripts. This topic provides an overview about the Rational Functional Tester behavior on Linux.

Test applications using Rational Functional Tester on Linux

Functional test scripts

All of the functionality of the product works on Linux except for the recorder. You can test the applications using RFT on Linux in two different ways.

Verification points

You can also insert verification points without recording, by opening the Verification Point wizard from the Script Explorer.

Launcher scripts

Functional Tester provides the following scripts that can be executed from the command-line:

ClearCase® integration

The Functional Tester ClearCase integration works on Linux, but there may be slight differences.

Datapool functionality

The datapools functionality works on Linux, but there may be slight differences.

Java and HTML support

On Linux, you can only test Java and HTML applications. Some Linux GUI applications, like those developed with Motiff, are not supported.

Install Functional Tester on Linux

When you install the Functional Tester package, the only feature you can install on Linux is Functional Tester, Java Scripting.

Start the test application outside the script

If you start your test application on Linux outside Functional Tester (not using a startApp command or other script call), first set the environment variables. You must make sure that the LD_PRELOAD and RATIONAL_FT_INSTALL_DIRECTORY are properly set in the environment from which they start the test application, else Functional Tester will not be able to properly play back scripts against the application.

Set up the following variables depending upon the shell that you are using.

export FUNCTIONAL_TESTER_DIR= <RFT install directory> For e.g, /opt/caspian







For HTML based test applications, the LD_LIBRARY_PATH must be set to the browser installation directory.

Alternatively, you can use rtsetup script to set all the functional tester environment variables. Refer to the Launcher scripts section.

Enable JREs or Browsers on Linux

To run the enabler for enabling the JREs and browsers on Linux, have root privileges.

Functionality not supported on Linux


You cannot record on Linux. You can record scripts on Functional Tester, Java Scripting on Windows and then play them back on Linux. For more information, see Guidance for Using Functional Tester on Linux.

Integration with TestManager and other Rational Products

The Rational TestManager main application does not run on Linux. But you can install TestManager Agent on Linux and run Functional Tester scripts in that agent. You must also install the Rational Functional Tester agent software on your agent computer.

The integrations with Rational Robot and Rational Administrator do not work on Linux.


The tutorials provided with Functional Tester involve recording scripts. If you want to learn the product functionality, we recommend that you do the tutorials on the Windows platform. You can play back the scripts you recorded using the tutorial on Linux.
