- [Instructor] We have verified that our recipe store…handles a nullDirectory properly.…Let's actually read the recipes out of…our assets directory of the app.…Go ahead and click on assets,…and you can see that under the recipes directory,…there are four recipes.…We will verify that they can be read from…the recipe store correctly.…Copy and paste the nullDirectory test method…from line 11 to 18.…
Change the name to count,…because we are going to verify the count…of the number of recipes in the assets folder.…In line 23, instead of passing null after directory name,…we will pass recipes,…which corresponds to the folder name under assets.…Look at the next line.…It says assertnotnull, which is still true.…We still want to make sure…that this recipe store in notnull.…
The next line we are asserting that…the recipes within the store is notnull,…which again is the same.…But the final line asserts equal should not be zero,…because we're expecting that…we are going to have four recipes.…Just for the sake of argument,…let's run the test and see it fail.…
