# google-readability-avoid-underscore-in-googletest-name: The rationale behind this is explained in the GTest FAQ. Basically, it avoids illegal or duplicated names created by GTest based on the inputs to TEST_F.
# -readability-function-size, -readability-function-cognitive-complexity: Disabled because our functions are too complex at the moment and refactoring needs to be done separately.
# -modernize-concat-nested-namespaces: We don't actually use C++17 yet, so we need to disable C++17 fixes.
# -cppcoreguidelines-non-private-member-variables-in-classes, -misc-non-private-member-variables-in-classes: They make our code more complex without much benefit.
# -cppcoreguidelines-pro-type-vararg: Many false positives due to macro usage in ROS2.
# -cppcoreguidelines-pro-bounds-array-to-pointer-decay: Many false positives due to macro usage in ROS2.
# -modernize-use-trailing-return-type: We don't follow this style.
# -modernize-pass-by-value: Might be considered at a later point.
# -modernize-avoid-bind: For now disabled. We use std::bind in many cases, where std::bind_front would be a better fit if we had C++20
