Seems like there is no need for shadowing in this type of test (integrational/acceptance)
Define NetCat's separate method for parallel execution. It's used for RECEIVE operation only.
Other ops and test use ordinary (serial) execute. It's simplifies test because there is no
need to call NetCatTask's execute() directly.
Add android-fest for future use. Replace assertEquals to assertThat.
