I am using gwtmockito 1.1.5

java.lang.ClassCastException: com.google.gwt.core.client.JavaScriptObject$$EnhancerByMockitoWithCGLIB$$c39d8300 cannot be cast to com.google.gwt.dom.client.Element at com.google.gwt.user.client.ui.HTMLTable$CellFormatter.getCellElement(HTMLTable.java:428) at com.google.gwt.user.client.ui.HTMLTable$CellFormatter.getRawElement(HTMLTable.java:441) at com.google.gwt.user.client.ui.HTMLTable$CellFormatter.access$400(HTMLTable.java:161) at com.google.gwt.user.client.ui.HTMLTable.cleanCell(HTMLTable.java:1578) at com.google.gwt.user.client.ui.HTMLTable.setText(HTMLTable.java:1175) at com.google.gwt.user.datepicker.client.DefaultCalendarView.setup(DefaultCalendarView.java:249) at com.google.gwt.user.datepicker.client.DatePicker.(DatePicker.java:306) at com.google.gwt.user.datepicker.client.DatePicker.(DatePicker.java:285) at com.kf.amplifire.modules.widgets.KfDatePickerCellTest.testImaMonkey(KfDatePickerCellTest.java:17) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.runners.BlockJUnit4ClassRunner.runNotIgnored(BlockJUnit4ClassRunner.java:79) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:71) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:49) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at com.google.gwtmockito.GwtMockitoTestRunner.run(GwtMockitoTestRunner.java:301) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

My test class looks like this: package com.a.bc.modules.widgets;

import static org.junit.Assert.assertTrue;

import org.junit.Test; import org.junit.runner.RunWith;

import com.google.gwt.user.datepicker.client.DatePicker; import com.google.gwtmockito.GwtMockitoTestRunner;

@RunWith(GwtMockitoTestRunner.class) public class KfDatePickerCellTest {

@Test public void testDatePicker() {

  DatePicker nosePicker = new DatePicker();
  assertTrue(nosePicker != null);

}

}

I just changed our code where we do: new DatePicker() to GWT.create(DatePicker.class) and now gwtmockito can return a mock and I do not get the same exception and I can now write unit tests.
