Description

Here's a unit test to show how the escape/unescape cycle doesn't return expected String.

 

@Test
public void testUnscape() {
  String unscapeString = "double quote: \" and a forward slash: /";
  String escapeString = StringEscapeUtils.escapeJson(unscapeString);

  assertEquals("double quote: \" and a forward slash: \/", escapeString);
  assertEquals(unscapeString, StringEscapeUtils.unescapeJson(escapeString));
}
