Explanation

The following JUnit test case gets a single page as a node. The properties "pageTitle" and "pageContent" are set for each node.

JUnit TestCase

 @Test
  public void testGetPage() throws Exception {
    debug=true;
    MediaWikiSystem mws = new MediaWikiSystem();
    MediaWikiPageNode pageNode = (MediaWikiPageNode) mws
        .connect("https://en.wikipedia.org", "/w")
        .moveTo("Cologne");
    if (debug)
      pageNode.printNameValues(System.out);
    String pageContent=pageNode.getProperty("pageContent").toString();
    assertTrue(pageContent.contains("[[Category:Cities in North Rhine-Westphalia]]"));
  }
