ngMocks.stub

ngMocks.stub is needed in case if we want to create stub methods / properties of a service.

If there is an existing value / spy we want to set, then use ngMocks.stubMember.

  • ngMocks.stub( service, method )
  • ngMocks.stub( service, methods )
  • ngMocks.stub( service, property, 'get' | 'set' )

Returns a mock function / spy of the method. If the method has not been replaced with a stub yet - it will.

const spy: Function = ngMocks.stub(instance, methodName);

Returns a mock function / spy of the property. If the property has not been replaced with a stub yet - it will.

const spyGet: Function = ngMocks.stub(instance, propertyName, 'get');
const spySet: Function = ngMocks.stub(instance, propertyName, 'set');

Or override properties and methods.

ngMocks.stub(instance, {
  existingProperty: true,
  existingMethod: jasmine.createSpy(),
});
