Is this actually necessary?

[Bill Hesse, 2015/08/10 11:37:43]

No, this is not needed.  Only those tests that are in a package themselves get a
package_root that is constructed by calling this.
Since there is no packages.yaml in the directory containing the tests, or above
that dir, they don't get a special package directory when these options
(--use-repository-packages or --use-public-packages) are used.

       // Generate dependency overrides if we use repository packages.
       var packageDirectories = {};
       if (configuration['use_repository_packages']) {
         packageDirectories = new Map.from(localPackageDirectories);
         // Do not create an dependency override for the package itself.
         if (packageDirectories.containsKey(packageName)) {
           packageDirectories.remove(packageName);
         }
       }
       var overrides = buildPubspecDependencyOverrides(packageDirectories);
 
       commands.add(CommandBuilder.instance.getModifyPubspecCommand(
           pubspecYamlFile.toNativePath(), overrides,
           destinationFile: modifiedYamlFile.toNativePath()));
       commands.add(CommandBuilder.instance.getPubCommand(
           "get", pubPath, checkoutDirectory, pubCacheDirectory.toNativePath()));
       if (new Directory(packageLinkTarget.toNativePath()).existsSync()) {
         commands.add(CommandBuilder.instance.getMakeSymlinkCommand(
             packageLink.toNativePath(), packageLinkTarget.toNativePath()));
       }
       commands.add(CommandBuilder.instance.getMakeSymlinkCommand(
           expectLink.toNativePath(), expectLinkTarget.toNativePath()));
+      commands.add(CommandBuilder.instance.getMakeSymlinkCommand(
+          testDataLink.toNativePath(), testDataLinkTarget.toNativePath()));

Also not needed.
