Valid: false

Testing contract

Expected to fail

Scenario: Parse the file with a Go parser or compiler and inspect the diagnostic.
Expected result: Parsing fails because `func main(` opens a parameter list that is closed with `{` instead of `)`; `gofmt` and `go build` must both fail; gofmt in particular must leave the file untouched rather than emitting a reformatted but still-broken file. The file is 46 bytes over 5 lines, so the whole defect is visible at once and the reported position can be checked exactly.

What is a .go file?

Go (.go) is a plain-text source file for the Go programming language: a statically typed, compiled language from Google designed for simplicity and concurrency. It features goroutines and channels, a fast compiler, garbage collection, structs with methods, and interfaces, with a strict standard formatting.

How to use this file

Use an example .go file to test syntax highlighters, the Go compiler and vet, gofmt, linters, and parser or language-detection tooling.

How to use this file for testing

“Go — Intentionally Invalid” is a deterministic Novus Examples fixture for Error handling, Code parsing, Editor testing. Deliberately corrupt and invalid files, clearly labelled, for testing how your tool fails.

Documented properties for this file: intentionally invalid · go · intentionally invalid. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.

This is a short, known-correct source file. Run it through your syntax highlighter, linter, formatter, tree-sitter grammar, or parser, and open it in the in-browser editor to tweak and re-download. Each snippet exercises comments, string escapes, literals, and language keywords.
