Unit Test that needs a Dictionary item

[genckastrati]

Hello Umbraco Community,

I am experimenting with Unit Tests on our Umbraco 13 solution and am having trouble creating a Moq umbracoHelper object that actually returns a sample value, for example, Umbraco.GetDictionaryValue(“Home”).

The documentation here gives an example but the GetDictionaryValue is called in the method I want to test, and I can’t get it to work. Any guidance would be very helpful.

Hi @genckastrati

To mock UmbracoHelper and specifically dictionary keys you need to provide your mocked UmbracoHelper with ICultureDictionaryFactory, IUmbracoComponentRenderer , and IPublishedContentQuery

Dictionary keys are setup via the ICultureDictionary which in turn is setup in the ICultureDictionaryFactory in the CreateDictionary() method.

See the provided example which should work

Mock<ICultureDictionary> cultureDictionary = new Mock<ICultureDictionary>();

cultureDictionary.Setup(x => x["MY_KEY"])
    .Returns("expectedValue");

Mock<ICultureDictionaryFactory> cultureDictionaryFactory = new Mock<ICultureDictionaryFactory>();
cultureDictionaryFactory.Setup(x => x.CreateDictionary()).Returns(cultureDictionary.Object);

Mock<UmbracoHelper> umbracoHelper = new Mock<UmbracoHelper>(cultureDictionaryFactory.Object, Mock.Of<IUmbracoComponentRenderer>(), Mock.Of<IPublishedContentQuery>());

Thank you so much Jonathan! The mistake I was making was to put the Mock object under “SetUp()”. It works now. Thank you for your help!
