We propose a static compaction procedure to reduce the size of a test set comprised of two-pattern tests. The procedure reorders the tests in the test set to maximize the number of faults detected by adjacent patterns, thus allowing some of the tests to be dropped. In addition, the procedure removes redundant tests and redundant patterns, that can be omitted without reducing the fault coverage. Experimental results are presented to evaluate the effectiveness of the compaction procedure.
