• 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
