+ <question>
+ How can I parse JSON output using JWebUnit or HtmlUnit?
+ </question>
+ <answer>
+ <p>HtmlUnit, one of the underlying engines of JWebUnit, <a
href="http://stackoverflow.com/questions/2932857/html-handling-a-json-response";>does
not support direct
+ execution of Javascript functions</a>. You need to check beforehand
that the <code>Content-Type</code>
+ of the response is <code>application/json</code>, and then use a
different library to parse it.</p>
+
+ <p>For example, <a href="http://code.google.com/p/google-gson/";>Google
Gson</a> can be used to parse JSON, as follows:</p>
+
+ <source>WebResponse response = ((HtmlUnitTestingEngineImpl)
JWebUnit.getTestingEngine()).getWebResponse();
+
+// check content type
+assertTrue("Response type should be application/json, was: " +
response.getContentType(),
"application/json".equals(response.getContentType()));
+
+// parse JSON
+Gson gson = new Gson();
+String json = response.getContentAsString();
+JsonObject obj = new JsonParser().parse(json).getAsJsonObject(); // or
JsonArray, depending on the JSON content
+
+assertTrue("Object should have success field", obj.has("success"));
+String success = gson.fromJson(obj.get("success"), String.class);
+String username = gson.fromJson(obj.get("username"), String.class);
+String type = gson.fromJson(obj.get("type"), String.class);
+// etc</source>
