// N.B. the file ./node_modules/blockly-test should be a symlink to
// RELEASE_DIR (i.e. dist/) so that require will load the packaged
// version of blockly as if it were an external dependency.
//
// Moreover, (as with the typescript tests) this link has to be
// called something other than "blockly", because the node module
// resolution will favour loading the nearest enclosing package
// of the same name, which means that require('blockly') will load
// based on the exports section of the package.json in the repository
// root, but this fails because (at the time of writing) those paths
// are relative to RELEASE_DIR (dist/, into which package.json is
// copied when packaged), resulting in require() looking for the
// compressed bundles in the wrong place.
