Traditional test suite reduction method generates test case set directly from the testing requirement set.Although the test case can be reduced

the method ignores the problem of redundancy testing requirements

results in inaccuracy. Aiming at this problem

a program slicing technique based on the method of six-element structure table is proposed. Program slicing is used to streamline test code

for saving the complex steps depending on graphic constructure. Use heuristic algorithm to reduce testing requirements based on the correlation between code and coupling degree between modules. After reducing test requirements

streamline test suite. The method is applied to the Android platform

to compare G and GRE algorithm case set before and after reduction. Experimental result shows that the testing requirement set after reduction ensures a higher coverage rate when it obtains less test suite.
