and only the overall execution of the test binary would fail.
</p>
<p><!-- CL 32455 -->
The signature of the
<a href="/pkg/testing/#MainStart"><code>MainStart</code></a>
function has changed, as allowed by the documentation. It is an
internal detail and not part of the Go 1 compatibility promise.
If you're not calling <code>MainStart</code> directly but see
errors, that likely means you set the
normally-empty <code>GOROOT</code> environment variable and it
doesn't match the version of your <code>go</code> command's binary.
