As per this bug report:
https://github.com/toniblyx/prowler/issues/693
Add detection for freebsd releases which should be similar to darwin
in that it will use GNU coreutils for date and base64.
If the -J flag is passed, generate JUnit XML reports for each check, in-line with how Java tools generate JUnit reports.
Check section numbers equate to 'root packages', checks are second-level packages, each check equates to a testsuite (mirroring Java where each test class is a testsuite) and each pass/fail of a check equates to a testcase
Time the execution of each check and include this in the report
Include properties (Prowler version, check level etc.) in-line with standard JUnit files
XML escape all strings for safety
Detect if a user has GNU coreutils installed on Mac OS X, but not as their default, switching to using gdate for date commands if so, as it has more features, including getting dates in milliseconds
Add prowler-output, junit-reports and VSCode files to .gitignore
Update README to include JUnit info, address markdownlint warnings
Remove unused arguments to jq in generateJsonAsffOutput
Fixes#537
As some users may have installed GNU coreutils on Mac OS X, e.g. `brew install coreutils`, it's possible that
the `date` command uses the GNU version, instead of the standard BSD version.
- Detect if GNU coreutils is installed on Mac and if it is, use the GNU variants of date functions
- Reduce some of the duplication in the file, which resolves a bug where the cygwin version of `how_many_days_from_today()`
had the operands switched around, leading to a positive result instead of negative
- Add test_tcp_connectivity function for cygwin (uses the GNU variant)
Fixes#534
