A testing system is provided for an article wrapped with an overwrap. The testing system includes first and second receptacle portions cooperating to define a test receptacle having a test fixture therein. The test receptacle is configured to receive the wrapped article. The test fixture is configured to form a seal with the test fixture about a perimeter thereof and to draw a portion of the overwrap away from the article in response to a suction applied in association with the test fixture. A piercing device is configured to form an orifice in the overwrap, within the perimeter, and a fluid between the overwrap and the article, through the orifice, from a fluid source. A pressure and/or a fluid flow change within the test receptacle, externally to the overwrap, is measured with a measuring device to determine whether there is leakage in the overwrap. An associated method is also provided.
