Well, it talks about the dependency tests inside on e class. I have two classes. Say for example ClassA & ClassB. ClassA is having a1,a2,a3 methods. ClassB is having b1,b2,b3 methods. b1 method is depending on a1 method which is another class. How dependsOnGroup works here. Cross level dependsOnGroups will support ?

Cedric,

Do you anticipate producing/releasing an updated version of the TestNG book at some point in time?

Warmest regards,
Andy

It’s not about topological sorting and concurrency but… I realize of really poor the single-threaded default sort algos in Java where. It occured to me on a 16-cores / 20 GB of ram OS X machine: it was pathetic to see only one core doing the sort. I implemented a correctly multi-threaded sorting algo and boom, instant ‘times x’ speed increase. It’s weird for a language offering so many features and API related to concurrency to have such basic thing as sorting using only a single thread and slowing to a crawl on a desktop 16-cores machine.

nice…
How about?
1) Create the dependency graph.
2) Have a thread at each root-node just traverse the graph, depth-first or breadth-first and execute each node? also nodes need to be locked from execution if a thread already visited it.

Okay, I am working with the JetBrains folks to get what I need. It sounds like it won’t happen for a while because they say there is a bug in TestNG 5.10 (which they also note is actually fixed in trunk), so they’ll wait for a bug-fix version (or I’m thinking probably just 5.11) before incorporating it into a new plugin.
Meanwhile, oh I can’t wait for 5.11 to come out of beta because I just wrote a test suite that wants smarter dependency analysis. Thank you so much for the continued work on TestNG .

The @Priority annotation couldn’t be adapted to say which free methods get scheduled first? BTW, the responsibility of knowing which nodes are free couldn’t be moved to the graph of test methods?

Yes, there is a TestNG plugin bundled with the IDEA download, but it uses an older version of TestNG (something like 5.6, but I’m not sure because I am not currently on the computer with IDEA installed). The IDEA 9 beta is using the same plugin as 8 used, so I suspect that the JetBrains branch of the plugin is stalled.
I would love to use the multi-threading DataProvider support from 5.10, and this new Executor would be nice to have as well. And of course those aren’t in the current IDEA plugin.
How does the layering work for this plugin? Can I just change out some jar files to get these new features, or is there coding work to be done in the plugin itself to enable these things? I would love some directions if it’s a simple jar file transplant, and I would be happy to help if coding is required. And I don’t really know how the ownership model works for the plugin right now . . .

IntelliJ IDEA comes with the TextNG plugin bundled out of the box. Which features are you missing?

Oh that is very cool. It makes me want a new version of the IntelliJ plugin even more . Is there anything I can do to bring the IDEA plugin back to life? I see there’s a Google Project for it, but it looks pretty stale and I guess the most recent version was made by the JetBrains folks? But that hasn’t moved in a while. Anyway, please let me know if there’s any way I can offer some constructive help (besides just nagging). Ah . . . I don’t think I’ll post my email here though, because I don’t need that much spam.
