- [Instructor] For our first test method, let's test a case…when the recipe is not found.…Create a new test method…by starting with the annotation Test.…Then public void recipeNotFound.…To test the case when recipe is not found,…what we are going to do is we are going to call…the load recipe function and then specify that…whenever somebody tries to load anything out of the store,…we return a null object.…
To specify that behavior of the store,…we are going to use Mockito.…Here is how you do it.…Mockito.when…store.getRecipe…and then Mockito.anystring go to the end of the line,….thenreturn, null.…Wow, that is not obvious at all,…So let's walk through it.…When we say Mockito when, and then return,…it means that we are specifying the behavior…when a function is called.…
Here, we are saying that when the get recipe function…is called on the recipe store,…whatever the perimeter is,…that's what we mean by Mockito dot any string,…we are going to return null.…We are doing that so that…when call presenter dot load recipe,…it can go to the store, and then return a null.…
