In vitro tests are done in test tubes or petri dishes; in vivo is the opposite, and literally means that it is done in a living organism.

The advantages of in vitro tests are that they can be done quickly and cheaply; tests can be done on different types of cells in vitro that could not ethically (or easily) be done on animals. A disadvantage is that because the test is NOT done on a complete organism, the results obtained may not apply in an intact plant or animal because of other systems functioning in the organism.
