I have a simple viewPart offering some text fields to enter parameters for a selenium test. After filling out these fields the user may start the test which approx. needs 30-45 minutes to run. I want my GUI to be alive during this test giving users the chance to do other things. I need a progress monitor.

I tried to put the selenium test in a job containing Display.getDefault().asyncExec to run it. But my GUI freezes after some seconds giving the busyindicator. The selenium does not update any other view but the progress monitor.

Is there another way to ensure that the job wont block my GUI?

Best, Mirco

I would suggest to split your code into code that updates the UI and the code that executes other business. Execute all of it in a separate thread, and when you need to retrieve or set some action to the UI then use the "Display.getDefault().asyncExec".

Thread thread = new Thread("Testing") {

    public void run() {

        someBusiness();

        // or use syncExec if you need your thread
        // to wait for the action to finish
        Display.getDefault().asyncExec(new Runnable() {

            @Override
            public void run() {
                // UI stuff here
                // data retrieval
                // values setting
                // actions trigging 
                // but no business
            }

        });
        someBusiness();
