Create Tests for Diff Studio Demo Model

Create tests for a Diff Studio model defined in the TS file at the path specified in the argument.

Instructions

1. Parse input: extract the path to the TS file from the argument. Verify the file exists and has a .ts extension.

2. Read the TS file: open it and locate the single exported object of type ModelInfo. Note:

   • The export name (e.g., export const myModel: ModelInfo = { ... }).
   • The equations field of the exported object.

3. Extract the file name: derive the base file name (without directory path and without the .ts extension) from the given path. This will be used as the test case name.

4. Update the test file src/tests/demo-models-tests.ts:

   a. Add import: at the top of the file (with other imports), add:

      import { <exportName> } from '<relative-path-to-ts-file>';

  Use the correct relative path from `src/tests/` to the target file (without the `.ts` extension in the import path).

b. Add test case: inside the 'Demo models' category block, add a call to testTemplate (imported from ./test-utils):

      testTemplate('<file-name>', <exportName>.equations);

  - First argument: string with the TS file name (e.g., `'my-model'`).
  - Second argument: the `equations` field of the imported `ModelInfo` object.

c. Placement: add the new test case in alphabetical order relative to existing test cases, or at the end of the 'Demo models' category if ordering is not established.

Example

Given argument: src/demos/acid-base.ts

If the file exports:

export const acidBase: ModelInfo = { equations: `...`, ... };

Then in src/tests/demo-models-tests.ts:

import { acidBase } from '../demos/acid-base';
// ...
testTemplate('acid-base', acidBase.equations);
