This looks like just what the doctor ordered. I am going to show this some developers we have using flex, thanks for the post.

[...] (of Adobe Consulting) and Joe Berkovitz haven’t been resting on their laurels. With the release of FlexCover 0.50 a few months ago the Flash world finally has a decent code coverage tool. I’ve been using it [...]

Yes, it is possible to automate tests like this offline with flexcover-0.50 — it is a very important capability. In order to do so, you need to do the following:

1. start the CoverageViewer app from Ant and pass the .cvm file on the command line, plus the -output option to specify the .cvr file to which the report will be written.

2. have the unit tests call CoverageManager.exit() when they are done, rather than System.exit() or fscommand(”quit”). This ensures that all coverage data is flushed correctly before the program terminates.

Joe,

I will certainly test any online publication system when you have it.

For your second point, what I am trying to do is to run the unit tests during my nightly builds (using a system similar to antennae by running the flash player and communicating the results via sockets). Is it possible to run the unit tests “offline” like this and save the results so that they can then be displayed in my maven site?

Thanks,

Julian

Hi Julian –

#1: We are thinking about how to best publish results online, and I see your point about the SWF. It’s a great idea and I’ll look into it.

#2: when you open a .cvm file, all percentages will always be at 0% because you have not captured any data yet. Once the coverage viewer is open on a .cvm, you can run the instrumented program and flexcover will collect the coverage data from it. At that point you will see the percentages change on the fly.

This does look cool :-)

I have 2 comments:

1. It would be great to have a SWF as well as an air application so that the results can be published in a nightly build (ala maven2)?

2. I have tried using 0.50 with my maven2 build environment and it creates a .cvm file but all the methods are at 0%, any clues why this might be?

Thanks,

Wow, this is a really useful tool. Provides a nicer interface than the default profiler. I was trying to use this on my project (its an AIR app). I ran into this nasty byte code verification error: (Can you help?)

verify global/vu.core.util::isNullOrEmptyString()
stack:
