Try it in 3 steps

1. 1

   Enter the pinned stdouttrace example

   Install Git and Go 1.26.0 or later; fetch v1.47.0 and enter the official stdouttrace example directory. The first dependency download requires network access.

   git clone --branch v1.47.0 --depth 1 https://github.com/open-telemetry/opentelemetry-go.git otel-go-demo && cd otel-go-demo/exporters/stdout/stdouttraceCopy
2. 2

   Run the official Example as a test

   Mechanically convert the pinned example_test.go into an executable main, run the SDK with go run, and capture its formatted spans in stdouttrace-run.txt. No external Collector is needed.

   (tmp_dir=$(mktemp -d) || exit 1; trap 'rm -rf "$tmp_dir"' EXIT; tmp_main="$tmp_dir/main.go"; sed -e 's/package stdouttrace_test/package main/' -e 's/func Example()/func main()/' example_test.go > "$tmp_main" && (set -o pipefail; go run "$tmp_main" | tee stdouttrace-run.txt))Copy
3. 3

   Check span names and success

   Assert the Calculation, Addition, and Multiplication span names separately to verify that every operation in the official example was recorded.

   grep -F '"Name": "Calculation"' stdouttrace-run.txt && grep -F '"Name": "Addition"' stdouttrace-run.txt && grep -F '"Name": "Multiplication"' stdouttrace-run.txtCopy
