@Test public void testBulk() { Map<String, String> pd = new java.util.HashMap<String, String>(); pd.put("rwProp", "foobar"); pd.put("intProp", "3"); pd.put("booleanProp", "true"); pd.put("stuffs", "foo,bar,baz"); for (int i = 0; i < 10000; i++) { TestBean tb = new TestBean(); ObjectPropertyUtils.copyPropertiesToObject(pd, tb); assertEquals("foobar", tb.getRwProp()); assertEquals(3, tb.getIntProp()); assertEquals(true, tb.isBooleanProp()); assertEquals(3, tb.getStuffs().size()); assertEquals("foo", tb.getStuffs().get(0)); assertEquals("bar", tb.getStuffs().get(1)); assertEquals("baz", tb.getStuffs().get(2)); } }
