Hi,
adding special handling in JS for areas where HtmlUnit's simulation is
incomplete is surely a workaround... but fixing it is better ;-)
Rather that sleep, you can try <config easyajax="true".../>. It works
well with a lot of JS libraries... but not all :-(
Cheers,
Marc.

Since we couldn't wait, I have found a workaround. I am posting it here in
case it helps someone when using an unsupported JS function.
In flotr.js I just made a small modification:
---
this.ctx = c.getContext('2d');
this.octx = oc.getContext('2d');
// add these lines:
if (!(this.ctx.scale)) {
this.ctx.scale=function(x,y) {};
this.octx.scale=function(x,y) {};
this.ctx.translate=function(x,y) {};
this.octx.translate=function(x,y) {};
}
// then all is well:
if(!Prototype.Browser.IE){
this.ctx.scale(o.resolution, o.resolution);
this.octx.scale(o.resolution, o.resolution);
}
---
So the trick was to add the missing function through JS if they were not
available.
I am still curious about AJAX and <sleep> though?
Kind regards,
Anze

Hi Ahmed!
Thanks for the fast response, I really appreciate it!
It looks like the library needs functions scale(x,y) and translate(x,y) (I
have added them dynamically, through JS, and the tests started working).
So i guess this should be added to
host/canvas/CanvasRenderingContext2D.java: -----
/**
* Scale the user coordinate system of the canvas
* @param x the x
* @param y the y
*/
public void jsxFunction_scale(final double x, final double y) {
//empty
}
/**
* Translate the user coordinate system of the canvas
* @param x the x
* @param y the y
*/
public void jsxFunction_translate(final double x, final double y) {
//empty
}
-----
Any chance someone could add this to trunk?
Also, how about adding full CanvasRenderingContext2D support? I can make
the stubs if it helps... The list is here: (for instance)

eference/WebKitDOMRef/CanvasRenderingContext2D_idl/Classes/CanvasRenderingC
ontext2D/index.html
Thanks!

Hi Anze,
Regarding "Cannot find function scale in object [object
CanvasRenderingContext2D]", this can be easily fixed in HtmlUnit be
empty implementation.
Please have a look in the current implementation [1] and list all
functions you need to skip.

Subject: [Webtest] Prototype AJAX
Hi all!
We are starting out with WebTest and would appreciate some help... :)
1) we are making AJAX calls and found that you had to use <sleep> to wait
for the call to finish. Now, this is awkward - why would someone ever
want to do something in a test before AJAX finished? Is there any wait to
say "wait for all AJAX to finish"?
2) we are using Flotr library for drawing graphs. However, it doesn't
play nicely with WebTest:
TypeError: Cannot find function scale in object [object
CanvasRenderingContext2D].
Since we do not intend to test Flotr charts at this point, we would like
WebTest to skip Flotr.draw() JS function. The only way I can think of is
to set a cookie in test files and then check for cookie before calling
Flotr.draw. Is there a nicer way to do it?
Of course, tips on how to fix JS support for Flotr would be even
better...
:)
Thanks,
Anze
