Usage

Generate test cases

node ./testCaseFactory/createCase.js fileCount caseCountInFile cpuSpendMillisecond ioSpendMillisecond

# Generate fileCount test files (fileCount must be a multiple of 10), and generate caseCountInFile test cases in each file (caseCountInFile must be a multiple of 5).
# The total number of test cases (fileCount * caseCountInFile) must be less than 100000.
# Time spent of cpu simulating business functions (ms).
# Time spent of io simulating business functions (ms).

#Example：node ./testCaseFactory/createCase.js 100 10 500 500

Run benchmark
