Join Ketkee Aryamane for an in-depth discussion in this video Test custom constructors, part of Java EE 8: JSON-B.
- [Instructor] So now let's go ahead and test the scenario.…Let's make a class under the tests folder.…Let's call it TestCustomCreator.…Let's grab the main method, psvm.…Let's create an empty Jsonb instance.….create…So once you get that instance, what you're going to do is,…if you observe, this is our project folder,…and we have saved the order details file.…
So this is a JSON document.…Now, we're going to read this JSON representation…and then employ the custom creator for that.…Okay.…So let's go to the code.…Let's say jsonb.fromjson…And we'll employ the file reader to read that file,…which will demand a file object.…So we'll do that.…And it'll also demand the path of the object,…so that will be orderdetails.txt…And, of course, the type will be OrderDetails this time.…
OrderDetails.class…That's what we have to mention.…Okay.…And what we'll also do is we'll take the output of this…inside an OrderDetails object.…That's what we have to check, correct?…So ...…Okay.…Now, since we are reading the file,…of course it's going to throw the checked exception.…
