• core/cautils/datastructuresmethods_test.go: Added unit tests for the ruleWithKSOpaDependency function, covering cases when attributes are nil, do not contain 'armoOpa' key, contain 'armoOpa' key with non-boolean value, and contain 'armoOpa' key with value 'true'.

@vladklokun @Daniel-GrunbergerCA Looking up at the repo history I see you might have a clue if the armoOpa attribute is still relevant?
I searched for it in regolibrary and it looks like a thing of the past, if so, we can get rid of the ruleWithKSOpaDependency function

[Daniel-GrunbergerCA]

Doing a search into the regolibrary repo, I can't find any reference to it, so it seems like it's deprecated

[cbrom]

@amirmalka should I get rid of the function and its usage at https://github.com/kubescape/kubescape/blob/master/core/cautils/datastructuresmethods.go#L36

@cbrom yes, it looks like it's not used in any of our controls

[cbrom]

@amirmalka I've removed the function along with its usage and added type safe checks and tests to other function.

• 🔒 Security concerns: No security concerns found

PR Feedback

• 💡 General suggestions: The PR is well-structured and the changes are clear. The addition of tests and the refactoring of the function to handle type assertion are good improvements. However, it would be beneficial to ensure that all edge cases are covered in the tests.

• 🤖 Code feedback:

  • relevant file: core/cautils/datastructuresmethods.go
    suggestion: Consider adding error handling for the type assertion of the 'useFromKubescapeVersion' and 'useUntilKubescapeVersion' attributes. If the type assertion fails, it could lead to a panic. [important]
    relevant line: "+ if sfrom, ok := from.(string); ok {"

  • relevant file: core/cautils/datastructuresmethods.go
    suggestion: It would be beneficial to add a default case to the type assertion to handle unexpected types. This would improve the robustness of the code. [medium]
    relevant line: "+ if suntil, ok := until.(string); ok {"

The type assertion works fine for string and does not lead to panic.

                        if sfrom, ok := from.(string); ok {
				if semver.Compare(version, sfrom) == -1 {
					return false
				}
			} else {
				// Handle case where useFromKubescapeVersion is not a string
				return false
			}

@matthyx I was doing a code improvement on this :( to use switch case for type assertion and remove unnecessary if else conditionals. Should I create a new PR?
