AFAIK the new style is to not test constructors, inputs, etc.
Just perform().

+    Map<String, TaskInput> inputs =
+        GenerateOptionsErrorsTask.buildInputs(source);
+    expect(inputs, isNotNull);
+    expect(inputs.keys,
+        unorderedEquals([GenerateOptionsErrorsTask.CONTENT_INPUT_NAME]));
+  }
+
+  test_constructor() {
+    GenerateOptionsErrorsTask task =
+        new GenerateOptionsErrorsTask(context, source);
+    expect(task, isNotNull);
+    expect(task.context, context);
+    expect(task.target, source);
+  }
+
+  test_createTask() {
+    GenerateOptionsErrorsTask task =
+        GenerateOptionsErrorsTask.createTask(context, source);
+    expect(task, isNotNull);
+    expect(task.context, context);
+    expect(task.target, source);
+  }
+
+  test_description() {
+    GenerateOptionsErrorsTask task =
+        new GenerateOptionsErrorsTask(null, source);

+    TaskDescriptor descriptor = GenerateOptionsErrorsTask.DESCRIPTOR;
