Thread UI

Dear List,

I am extending the current set of Mondrian tests. I would like to  
force some system window to appear on the screen in order to properly  
test the size of its composing morphs. However, I do not know how to  
effectively make the morph show up on the screen in a test.

For example, consider the following test with a contrived situation:

testDummy
        | morph c |
        morph := Morph new openInWorld.
        c := Display colorAt: 0@0.
        morph delete.
        self assert: c = morph color.

If I run the test from a test runner, it will fail. However, if I open  
a debugger and do a step by step, c = morph color is true.

I guess the problem is that the morph is not actually displayed, since  
the UI thread does not have the hand. Any idea how to force this?

Cheers,
Alexandre

between the lines
morph :=
and
c :=

From a test-clarity (and robustness) POV though, you'd be much much
better by instead asserting properties of the morphs layout/colors than
sampling of display colors...
| morph |

        morph := Morph new.
        morph doLayoutIn: someBounds.
        self assert: whatIExpectedWithAboveBounds equals: morph someLayoutVariable

Also have a look the OB and Glamour morphic tests. They mostly does
not display the actual morph to test it.

Woaaa... Thanks Henrik!
This is really cool!

I also do some extensive test on Mondrian without displaying the  
thing. I wanted to test whether a scrollbar appears in a ScrollPanel  
under certain condition.

Thanks for all your replies.

Cheers,
Alexandre
