title: Send go test coverage output to stdout - send it to S3
body: <p>I want to send the html for <code>go test -c</code> to stdout, so I can serve the resulting HTML from S3 static assets server.</p>
  
  <p>Something like this:</p>
  
  <pre><code>arti_fact="s3://cm-html/cm-api/$commit_sha"
  
  go test -coverprofile cover.out .
  go tool cover -html=cover.out -o /dev/stdout  | aws s3 cp - "$arti_fact"
  </code></pre>
  
  <p>is there a way to write to stdout without using <code>-o /dev/stdout</code>?</p>
