### Question:
RecyclerMixin implements Mixin { @SuppressWarnings("NullableProblems") public RecyclerView getRecyclerView() { return recyclerView; } RecyclerMixin(@NonNull TemplateLayout layout, @NonNull RecyclerView recyclerView); void parseAttributes(@Nullable AttributeSet attrs, int defStyleAttr); @SuppressWarnings("NullableProblems") // If clients guarantee that the template has a recycler // view, and call this after the template is inflated, // this will not return null. RecyclerView getRecyclerView(); @SuppressWarnings("NullableProblems") // If clients guarantee that the template has a header, // this call will not return null. View getHeader(); void onLayout(); Adapter<? extends ViewHolder> getAdapter(); void setAdapter(Adapter<? extends ViewHolder> adapter); @Deprecated void setDividerInset(int inset); void setDividerInsets(int start, int end); @Deprecated int getDividerInset(); int getDividerInsetStart(); int getDividerInsetEnd(); Drawable getDivider(); void setDividerItemDecoration(@NonNull DividerItemDecoration decoration);  }### Answer:
@Test public void testGetRecyclerView() { RecyclerMixin mixin = new RecyclerMixin(mTemplateLayout, mRecyclerView); assertSame(mRecyclerView, mixin.getRecyclerView()); }
