> Please review this PR which speeds up TestTooManyEntries and clarifies its > purpose: > > - The name 'TestTooManyEntries' does not clearly convey the purpose of the > test. What is tested here is the validation that the total CEN size fits in a > Java byte array. Suggested rename: CenSizeTooLarge > - The test creates DEFLATED entries which incurs zlib costs and File Data / > Data Descriptors for no additional benefit. We can use STORED instead. > - The name of entries is generated by calling UUID.randomUUID, we could use > simple counter instead. > - The produced file is unnecessarily large. We know how large a CEN entry is, > let's take advantage of that to create a file with the minimal size. > - The summary and comments of the test can be improved to help explain the > purpose of the test and how we reach the limit being tested. > > These speedups reduced the runtime from 6 min 58 sec to 3 min 35 sec on my > Macbook Pro. The produced ZIP size was reduced from 6000000098 bytes to > 3655383762 bytes.
