Hi there,
I'm trying to use JSNI from within a GWTTestCase. The JavaScript object is
returned via a JSON response from a servlet I have running for the test. I
then eval the JSON and assert the corresponding overlay object's value.
Firstly, does this sound like a reasonable thing to do from within
GWTTestCase?
Here's my relevant bits of code. I have declared a parameterised class to
handle JSON payloads with the parameter representing the type of
JavaScriptObject I want to evaluate to:
public abstract class JSONRequestCallback<T extends JavaScriptObject>
implements RequestCallback {
private final native T evalJSON(String jsonText) /*-{
return eval(jsonText);
}-*/;
@Override
public void onResponseReceived(Request request, Response response) {
String responseText = response.getText();
onResponseReceived(request, evalJSON(responseText));
}
/**
* Handle a JSON payload response.
*
* @param request
* the original request object.
* @param response
* the JSON response marshalled as a JavaScript object.
*/
public abstract void onResponseReceived(Request request, T response);
}
To call it I issue an HTTP request with the callback provided like this in
my test:
new JSONRequestCallback<JsArray<SomeModelObject>>() {
@Override
public void onError(Request request, Throwable exception) {
fail("Should not get here.");
}
@Override
public void onResponseReceived(Request request,
JsArray<SomeModelObject> deals) {
// TODO Validate the response.
assertEquals(1, deals.length());
SomeModelObject bo = deals.get(0);
assertEquals("A", bo.getAccountProductType());
finishTest();
}
});
SomeBusinessObject is an overlay class with getAccountProductType declared
as follows:
public final native String getAccountProductType() /*-{
return this.accountProductType;
}-*/;
Unfortunately for me, the second assertion (for "A") fails. The servlet
definitely responds correctly and I can see via the debugger that eval is
being performed on the JSON response.
Any guidance is most appreciated.
Kind regards,
Christopher
