fs - create temporary files and compare a filesystem tree to an expected value
golden - compare large multi-line strings against values frozen in golden files
icmd - execute binaries and test the output
poll - test asynchronous code by polling until a desired state is reached
skip - skip a test and print the source code of the condition used to skip the test

gotest.tools/gotestsum - go test runner with custom output
go testing patterns - zero-dependency patterns for organizing test cases
test doubles and patching - zero-dependency test doubles (fakes, spies, stubs, and mocks) and monkey patching patterns
