  // Pub parses the "version" file that gets generated and shipped with the SDK.
  // Most of the pub tests here generate a synthetic SDK directory so that we
  // can tests against a known SDK state. But we want to make sure that the
  // actual version file that gets created is also one pub can parse. If this
  // test fails, it means the version file's format has changed in a way pub
  // didn't expect.
  //
  // Note that this test expects to be invoked from a Dart executable that is
  // in the built SDK's "bin" directory. Note also that this invokes pub from
  // the built SDK directory, and not the live pub code directly in the repo.
