                   IsElement { public String getDriverClass() { return view.getDriverClass(); } @Inject  DriverDefMainPanel(DriverDefMainPanelView view); void setHandler(DriverDefMainPanelView.Handler handler); @Override void onNameChange(); @Override void onDriverClassChange(); @Override void onGroupIdChange(); @Override void onArtifactIdChange(); @Override void onVersionChange(); @Override HTMLElement getElement(); void setName(final String name); String getName(); void setNameErrorMessage(final String message); void clearNameErrorMessage(); void setDriverClass(final String driverClass); String getDriverClass(); void setDriverClassErrorMessage(final String message); void clearDriverClassErrorMessage(); String getGroupId(); void setGroupId(final String groupId); void setGroupIdErrorMessage(final String message); void clearGroupIdErrorMessage(); String getArtifactId(); void setArtifactId(final String artifactId); void setArtifactIdErrorMessage(final String message); void clearArtifactIdErrorMessage(); String getVersion(); void setVersion(final String version); void setVersionErrorMessage(final String message); void clearVersionErrorMessage(); void clear();  }### Answer:
@Test public void testGetDriverClass() { when( view.getDriverClass() ).thenReturn( DRIVER_CLASS ); assertEquals( DRIVER_CLASS, mainPanel.getDriverClass() ); }
