Please, do not do that kind of assumptions. It seems easier to simply pass a
pair of { type, angle }.

I agree we generally shouldn't make this kind of assumption. However, this
method is used *only* for layout testing. Why is this a problem for testing? The
layout tests already assume that the default orientation is "portrait-primary"
for e.g.

+      break;
+    case blink::WebScreenOrientationLandscapeSecondary:
+      params.screen_info.orientationAngle = -90;
+      break;
+    case blink::WebScreenOrientationPortraitSecondary:
+      params.screen_info.orientationAngle = 180;
+      break;
+    default:
+      params.screen_info.orientationAngle = 0;
+  }
+  params.new_size = size();
+  params.physical_backing_size = gfx::ToCeiledSize(
+      gfx::ScaleSize(size(), params.screen_info.deviceScaleFactor));
+  params.overdraw_bottom_height = 0.f;
+  params.resizer_rect = WebRect();
+  params.is_fullscreen = is_fullscreen();
+  OnResize(params);
+}
