Integrating Guice with TestNG listeners

[Karthik Krishnan]

Hi

I am using TestNG 5.10 for unit testing and Guice 2.0 for unit testing. I have been able to hook up Guice with TestNG using IObjectFactory and @ObjectFactory annotation and it is working well. I have a question about scopes and listeners.

I used the custom scope implementation from Guice's user guide to generate thread local instances to be injected (Here is the link ; http://code.google.com/docreader/#p=google-guice&s=google-guice&t=CustomScopes) . The document states that to enter and exit the scope, the code should reside in a filter or an interceptor. I am implementing TestNG invoked method listener to enter and exit scopes. However, for the code to work, I need to inject the scope in my listener to start the seed and exit process.

This is what I am think may work. Please correct me if I am wrong. If I can get a handle to the ITestContext, i can get an reference to Guice injector stored as a context attibute. I can use the Guice injector to inject members into listener. I have looked through the code and can not figure out how I can get a handle to the reference. Can any one help?

Thanks,

Kartik

You can get the ITestContext in a @BeforeSuite method and store the injector in the attribute.  You can then retrieve this injector in the listeners through that same ITestContext.

Hi Cedric,

Thank you for replying but I can't figure out how to get  I need to implement IInvokedMethodlListener to get to implement before and after behavior. I can not figure out how I can access ITestContext from IInvokedMethod or ITestResult. IInvokedMethod#getTestMethod() returns ITestMethod instance. How do I get a handle to ITestContext.

Thanks,

Kartik

Is there a way to get a handle to ITestContext from either IInvokedMethod or ITestResult?

It's not possible at the moment, I'm considering introducing IInvokedMethodListener2 that would be just like IInvokedMethodListener but that would pass an ITestContext to the listener methods...

Hi Cedric,

Is there a work around?

 If you want, I can also take a look at defining and its invocation by the TestNGRunner/SuiteRunner. If you can point me to where I should look for, I will take a look at it?

Thanks,

Kartik
