 This means that for any two test cases, if their input, output validator arguments and the contents of their `.ans` files are equivalent, then the test cases are equivalent.
 The assumption of determinism means that a judge system could choose to reuse the result of a previous run, or to re-run the equivalent test case.

+Test cases and [test data groups](#test-data-groups) will be used in lexicographical order on test case or test group name.
 It is good practice to use a numbered prefix such as `00`, `01`, `02`, `03`, and so on, to get the desired order of test cases, while keeping the file names descriptive.
 Remember that the numbered prefixes should be zero padded to the same length to get the expected lexicographical order.
