Rename CompareType to compareResult to make it private. This type is used only in internal functions and is of no use for external users and should never have been made public. CompareType has been introduced by 0b4ff03cda5c8eb0150a14ffbaaa088fd777d6ba and appeared in releases since v1.6.0. Note: strictly speaking, this is a breaking change, but no external user should have ever used assert.CompareType as it made no sense in the assert API. A search on GitHub has revealed no use of it. https://github.com/search?q=assert.CompareType+language%3AGo&type=Repositories&ref=advsearch&l=Go&l=
