java - How should a custom Guice scope be integrated with TestNG? -

we use custom guice scope, @testscoped, of our junit tests lasts single test method, , junit @rule enter , exit scope appropriately. looks this:

public class myjunittest {     @rule public customrule customrule = new customrule(mymodule.class);      @inject private thing thing;      @test     public void test1() {         // use "thing"     }      @test     public void test2() {         // assuming "thing" @testscoped, we'll have new instance     } } 

we're starting use testng of our tests in other projects, , we'd have similar pattern. far we've come this:

@listeners(customtestnglistener.class) @guice(modules = mymodule.class) public class mytestngtest {     @inject private provider<thing> thingprovider;      @test     public void test1() {         thing thing = thingprovider.get();         // use "thing"     }      @test     public void test2() {         thing thing = thingprovider.get();         // assuming "thing" @testscoped, we'll have new instance     } }  public class customtestnglistener implements ihookable {     @override     public void run(ihookcallback callback, itestresult testresult) {         testscope.instance.enter();         try {             callback.runtestmethod(testresult);         } {             testscope.instance.exit();         }     } } 

there couple issues design:

• unlike junit, testng uses same instance of test class each method. means have inject provider<thing> instead of thing, awkward.

• for reason, customtestnglistener running on of our tests, ones don't have @listeners(customtestnglistener.class) annotation. i've worked around explicitly checking annotation in listener itself, feels hack (though see mockitotestnglistener same thing).

does more familiarity testng have suggestions dealing these issues?

instead of

public class mytestngtest {     @inject private provider<thing> thingprovider;      @test     public void test1() {         thing thing = thingprovider.get(); 

in testng can used

public class mytestngtest {     @inject      private thing thinginjected;     private thing thing;      @beforetest     public void dobeforetest() {         thing = thinginjected.clone();     } 

or call thingprovider.get() in dobeforetest(), it's better in have lot of @ test

public class mytestngtest {     @inject private provider<thing> thingprovider;     private thing thing;      @beforetest     public void dobeforetest() {         thing = thingprovider.get();     }
