EtherFuzz: Mutation Fuzzing Smart Contracts for TOD Vulnerability Detection

Algorithm 1

Test data generation algorithm.

Input: Sinterface:the ABI of the contract under test

Output:test data

1:   dataType=analyze(Sinterface);

2:   if parameterType==addresType then

3:    contractPool=GeneratePool(Sinterface);

4:    testdata=ranselectAddress(contractPool);

5:   end

6:   if parameterType==fixedType then

7:    testdata=ranselectData(fixedSize);

8:   end

9:   if parameterType==nonfixedType then

10:    length=randomNumber();

11:     testdata=ranselectData(length);

12:  end
