Abstract

A fast algorithm is given to produce a small set of short sentences from a context free grammar such that each production of the grammar is used at least once. The sentences are useful for testing parsing programs and for debugging grammars (finding errors in a grammar which causes it to specify some language other than the one intended). Some experimental results from using the sentences to test some automatically generated simpleLR(1) parsers are also given.
