Type: Bug Detection
Assertions are intended to be used in test code, but not in production code. It is confusing, and might lead to ClassNotFoundException when the build tools only provide the required dependency in test scope.
In addition, assertions will throw a sub-class of Error: AssertionError, which should be avoided in production code.
This rule raises an issue when any assertion intended to be used in test is used in production code.
Note: this does not apply for assert from Java itself or if the source code package name is related to tests (contains: test or assert or junit).
