  2. Overview • Selecting an integration testing strategy • Some OO integration testing strategies are compared. • Six real-world case studies of various complexities are considered (e.g., small telecommunications software, Swing Java Library) • Optimization problem – minimization of the number of stubs to the written (cost) and the number of steps needed to achieve the integration (duration) • Hahn, V., Akif, K., Traon, Y., Jezequel, J., Selecting an Efficient OO Integration Strategy: An Experimental Comparison of Actual Strategies, ECOOP’01, Lecture Notes in Computer Science, vol. 2072, pp. 381-401, 2001.

  3. Main Results • Four integration strategies and six real-world case studies • Integration strategies – Kung, Tai-Daniels, Genetic, Triskell • Case studies: • Telecommunication switching system (SMDS) • GNU Eiffel compiler (partial) • Interviews graphic library • Pylon Eiffel library (e.g., data structures) • Base classes of Java 2 Platform, v. 1.3 • Package Swing – Java 2 Platform, v. 1.3
