elm-graphql VS mocha

Once I could quickly make calls against a server, and see the raw responses were matching up to my expectations, I moved to finding an Elm equivalent. Two years ago or so, Dillon had his GraphQL library and marketed it well.

The elm-graphql library enables code generation. This enables us to extend the “fearless refactoring” across the entire stack. As we build, learn, and eventually change our domain model from those learning’s, we can regenerate the front-end code needed, and the compiler lets us know what to modify (I still haven’t found something this powerful for ReScript yet).

I've managed to run the example from dillonkearns examples at master, however it is using a strange version of Swapi/Object with CustomScalarCodecs instead of ScalarCodecs generated by his code generation utility. I'm new to Elm, so costed me some time to make the Starwars.elm file work with properly generated classes, since even Id types in the repo example are not matching the generated types (Int vs String).

MochaJS is a feature-rich JavaScript test framework running on Node.js, making it a popular choice for both backend and frontend testing. It's known for its flexibility and straightforward syntax, allowing for asynchronous testing and the use of any assertion library.

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

JavaScript Popular tools for testing: Mocha, Jasmine, Unit JS, Jest

To execute your tests, you can create test scripts using popular testing frameworks like Mocha, Jasmine, or Jest. These frameworks provide a structured way to organize and run your tests, report results, and handle assertions.

⚗️ Mocha and Chai for testing

Testing frameworks like Jest, Mocha, and Jasmine are crucial for software development, ensuring code reliability and correctness. They offer features like test suites, test cases, assertions, and asynchronous testing support.
