Is testing through secondary testing app white box testing? -

so software has 0 unit tests. can't test software unless whole system built , running. (this crap know)

they way these "white box" tests work:

• while whole system running, inject sequence of commands secondary testing app system directly rather going through user front, , verify if behavior correct testing app

• this allows isolated test cases scripted through testing app rather programming system manually, saving time

• the testing app not know code level details of software

is white box testing?
