vs unit testing framework - TFS Test runs reporting inconsistent count of tests run each build -

using microsoft.teamfoundation.build.activities.runagiletestrunner activity shipped vs2013rtm, have unit tests set this:

when run these builds, tests run fine, there different results in count beingness reported every time. not counts different between builds, build summary page given build run consistently shows different counts of tests actual test results (.trx) file.

i tried microsoft.teamfoundation.build.workflow.activities.runtests activity, , same issues test results described above. however, able utilize runteststestcompletedeventargs write build message of name of test followed result, , when see same number of tests run each time, means wrong summary study and/or published results (right? right???):

also, have 2 assemblies 'tests' in name picked filter, know aspect working because bin folder on build box have same size on disk among of different runs produce different results.

so, going on these numbers? doing wrong in build definition or on build box causing this?
