Create all API Resolver Tests

[palisadoes]

The Talawa-API code base needs to be 100% reliable. This means we need 100% test code coverage.

Our resolver test suite must cover all resolvers and function correctly.

This is a parent issue for resolver tests:

• We'll only assign the child issues.
• Please comment on one of the child issues for assignment.
• Only one child issue will be assigned to a person at any one time.

API Resolver File Template

The API resolver file will need to be refactored using these guidelines

API Function

This is the part of the file's code that accesses backend systems such as object storage and data storage. We require this code to have dedicated functions.

The function must:

• Perform a single resolver task based on user input parameters

• Perform a database or object storage call

• Delegate calculation, sorting, data structuring or usage of external packages to a separate non-API function in the same file.

• Response creator function if a particular unit task needs to be performed for some sort of structuring

• Return a response

• Note: You must ensure that if the API fails in any of the function's steps that all the previously executed database calls in the function are reversed.

Unit Function

This is the part of the file's code that does not access backend systems at all. We require this code to have dedicated functions.

The function must:

• Perform a single task
• Receive input as needed (ie. input provided by users)
• Perform the required calculation, sorting, data structuring or usage of external packages for the function's task
• Return the desired output, which is to be utilised in API Function

Other

It is possible that you may need to combine unit functions and database calls together to get the desired functionality. This is OK, however for make sure these functions mostly contain only unit functions. These combined functions must be tested also.

API Resolver Test File Template

Utilise the unit function to your test code to get the results and check the response.
