NOTE - I'm only new to Angular 7 and I had a go at developing a front-end solution using this framework. Unfortunately it was taking me too long as there are a number of required things that I am yet to learn so I am submitting a back-end solution only. I will continue to work on an Angular 7 solution as this is what I am studying at the moment.

Build a RESTFul API for a Address Book application. Build the corresponding database and tables. Each contact can have 0 to many corresponding addresses and phone numbers. The solution is back-end only.

• Download the files from https://github.com/scott-everett/GoLogicCodeChallengeBackEnd and copy to the desired local install location.
• Open the MyAddressBookAP\MyAddressBookAPI.sln file in Visual Studio (2017).
• Open Web.config and change the "MyAddressBook" connection string to point to the desired SQL Server instance.
• Select Build / Rebuild Solution.
• Open the Package Manager Console (Tools / Nuget Package Manager / Package Manager Console).
• Type "Update-Database" and press enter.

You can now run the API.

Format: JSON

GET api/Contacts - returns a list of all contacts.

GET api/Contacts/{id} - returns the contact with the specified id.

• params: id

PUT api/Contacts/{id} - modifies the contact with the specified id.

• params: id, contact

POST api/Contacts - adds a new contact.

• params: contact

DELETE api/Contacts/{id} - deletes the contact with the specified id.

• params: id

• I decided to use dependency injection of implementations of the custom IDbContext interface on the API controller (ContactsController) so that a fake DbContext can be used to test using local memory rather than utilizing the database.

• The testing does not have full coverage. I would normally test every condition path each method. This work is just a sample. I created unit tests for the FakeDbContext and the ContactsController.

• I do not have experience in automated intergration testing. My experience is just with unit testing. If I had more time I would have researched and included some of these tests. I would test that the API successfully receives and returns JSON data.

• If I have more time I could add authentication to the solution to secure contact data.

• I added the CORS package to the project. Currently this security is relaxed but can be set in Web.config if necessary. Current settings...
