I am not shure if there are any "testmethods" that are special to agile.
Of course there is "testdriven" (tdd) and "behaviordriven" (bdd) development but i donot see these as "testing methods".
Unittests are not special to agile or traditional.
As @khachik mentioned it: there is offen a huge difference when (in the develpment process) the tests are desigend and applied.
Traditional = Waterfall or V-Modell: Test are done in the end (if at all)
Agile : Test should be written before the code is written.
