| /** |
| * A convenience method to get a test fold with default values provided. With the default values |
| * it returns a [FoldingFeature.State.HALF_OPENED] feature that splits the screen along the |
| * [FoldingFeature.Orientation.HORIZONTAL] axis. |
| * |
| * The bounds of the feature are calculated based on [orientation], [center], and [size]. If the |
| * feature is [VERTICAL] then the top-left x-coordinate is [center] - ([size] / 2) and the top-right |
| * x-coordinate is [center] + ([size] / 2). If the feature is [HORIZONTAL] then the top-left |
| * y-coordinate is [center] - ([size] / 2) and the bottom-left y-coordinate is |
| * [center] - ([size] / 2). The folding features always cover the window in one dimension and that |
| * determines the other coordinates. |
| * |
| * @param activity [Activity] that will host the test [FoldingFeature]. |
| * @param center The coordinate along the axis matching the [Orientation]. The default is centered |
| * along the [HORIZONTAL] axis. |
| * @param size the smaller dimension of the fold. The larger dimension always covers the entire |
| * window. |
| * @param state [State] of the fold. The default value is [HALF_OPENED] |
| * @param orientation [Orientation] of the fold. The default value is [HORIZONTAL] |
| * @return [FoldingFeature] that is splitting if the width is not 0 and runs parallel to the |
| * [Orientation] axis. |
