Go Testing

Pick the assertion stack by what your project allows:

• Dependency-free project — stdlib testing only. No third-party assertions.
• Project that allows deps — use go-testdeep. Composable operators (td.Cmp, td.Struct, td.Smuggle, td.Between, …) produce precise diffs.
• Never use testify. Vague messages, the assert/require split, and interface{} comparisons are worse than either alternative.
