ExUnit vs Go testing

ExUnit has no write-up on Specifiction yet; its figures are above.

Go testing is the testing toolkit built into Go, an open-source programming language supported by Google. Developers run it with the `go test` command and `testing` package. It discovers test functions named `TestXXX` in files ending in `_test.go`; adding `-v` displays tests and their results. The standard toolchain also supports native fuzzing, which varies inputs to help find bugs, as well as benchmarking and profiling. The race detector can be enabled with `go test -race`, though it detects races only in code paths exercised during a run. For vulnerability checks, `govulncheck` identifies known issues affecting code and prioritizes them according to whether vulnerable functions or methods are called. Its JSON output can feed CI/CD systems, and the Go team provides a GitHub Action. Go is free and has releases for Linux, macOS, and Windows, along with source archives and other ports. Its cryptography libraries can be used in FIPS 140-3 compliant mode. The language is used for cloud and network services, command-line interfaces, web development, DevOps, and site reliability engineering.
