Organize Jest tests by method

[JohnAlbin]

Package

next-drupal (NPM package)

Describe the feature request

The current Jest tests are in two files:

• client.test.ts (2644 lines long)
• crud.test.ts (395 lines long)

Having a 2000+ lines long test file makes it more difficult than necessary to find the tests that relate to a particular piece of code.

Also, the tests seem to be organized around "features" rather than by the specific methods; for example, setting an option in the constructor should be a constructor test and how that option affects the different methods should be tested for in those methods and not grouped by the option name.

This last point is important because it makes it easier for the developer to see how the tests cover the codebase.

Lastly, some of the next-drupal tests appear to be testing the return values of the next.module and not testing the functionality of the next-drupal codebase.

Describe the solution you'd like

Fortunately, the crud tests are already organized by method name. But the client.test.ts file needs to be split up and organized by method name.
