This is testing PGraphics please update the class name, and place this in the core/test/processing/core folder

pg.setSize(200, 100); // canvas size

pg.beginDraw();
pg.rect(10, 10, 100, 50); // draw a rectangle
pg.endDraw();

this is not necessary since you are testing setSize

// Assert that the canvas width is 200 (not the rect width)
assertEquals(200, pg.width);
}

@Test
public void testCanvasHeightAfterSetSize() {
// Create a PGraphics object and set its size
PGraphics pg = new PGraphics();
pg.setSize(300, 150); // canvas size

pg.beginDraw();
pg.rect(20, 20, 50, 25); // draw another rectangle
pg.endDraw();

// Assert that the canvas height is 150
assertEquals(150, pg.height);
}

this test of the pg height can be done in the other test function that tests width.
