About using JavaFX WebEngine
Hello,
We had a discussion on using a more up to date browser (JavaFX one) in the
HTML renderer.
I think we also discussed of having it in our Roadmap for 2016/2017.
I made a little POC and it nearly works except that I think it may not suit
fully our need.
When it works the rendering is much better, you can see an example here at
the difference that we will be using loadContent (read below):
-
https://docs.oracle.com/javase/8/javafx/interoperability-tutorial/swing-fx-interoperability.htm
Note that with this implementation, we face Font issues.
My POC uses WebEngine#loadContent:
-
https://docs.oracle.com/javafx/2/api/javafx/scene/web/WebEngine.html#loadContent(java.lang.String)
The issue is that it doesn't load any resources (for security reasons it is
not allowed to, it can only load local resources) so for many websites the
rendering is not great.
Using WebEngine.html#load(Stirng url) might be better but it wouldn't
reflect what was downloaded by SampleResult.
Any thoughts or ideas ? Am I missing something ?

Hi,
Patch proposal at :
https://bz.apache.org/bugzilla/show_bug.cgi?id=60144
It would require a JAVA8 upgrade.
Regards
Philippe

Does that mean JMeter should spawn a HTTP server, so fx browser could fetch
exact page and relevant resources from it?

Hello,
I've been using the POC browser for 2 days now in a real-world scripting
campaign and even with the previous issues I mentioned in my mail it ends
up being very useful to identify the problems when a requests fails.
I compared old renderer and new one.
With the old one, I am nearly never able to find anything (rendering is
broken). With the new one, in 90% of cases I find the problem thanks to the
new view, so I think it is very useful.
There are 2 things to note:
- This feature will have to wait for JAVA 8 Migration to avoid complex
deployment and possible conflicts when using Java8 while we have to
distribute jars that are now in Java8 or in a more recent version
- I faced java crashes which I suppose reveals a Java8_u101 bug on MacOSX
at least since err_pid file is generated
Regards
Philippe
