how force mstest testmethod reset singletons/statics before running?

i'm controlling mstest inside visible studio 2008. i have any section exam slight certain exam category act initial exam run tellurian state reset before controlling any test? i wish definitely purify adult universe controlling testinitialize, classinitialize, assemblyinitialize, etc. example:

[testclass]
public category myclasstests
{
    [testmethod]
    open vacant test1()
    {
       // "instance" ability creates new instance "somesingleton"
       // hasn't combined before.
       var i1 = somesingleton.instance;
       ...
    }
    [testmethod]
    open vacant test2()
    {
       // i name "test1" "test2" run, i'd test2
       // have new appdomain feel stationary non-static inside
       // "somesingleton" reset (it formerly set test1) on
       // ".instance"
       var i2 = somesingleton.instance;
       // code
    }

although seemed topic, wholly simplified tests run parallel. i comprehend tests run serially, nonetheless there doesn't seem proceed definitely force new appdomain any slight (or something homogeneous pristine state).

ideally, i'd mention function wholly little subset section tests i don't have compensate chastisement new appdomain origination tests don't caring tellurian state (the infinite decrease tests).
