Macro polkadot_sdk_frame::testing_prelude::assert_err_ignore_postinfo

macro_rules! assert_err_ignore_postinfo {
    ( $x:expr , $y:expr $(,)? ) => { ... };
}

Other helper macros from frame_support that help with asserting in tests. Assert an expression returns an error specified.

This can be used on DispatchResultWithPostInfo when the post info should be ignored.
