# Housekeeping tasks
- [x] Organize tests?
- [x] More documentation in docs/
- [ ] Rename/consolidate, lossless view() and compose() --> composeView()
- [ ] Rename Lossless to HyperView
- [ ] Rename Lossy to View
- [ ] Consider whether we should use collapsed deltas
- [ ] Improve ergonomics of declaring multiple entity properties in one delta
- [x] Use dotenv so we can more easily manage the local dev test environment
- [ ] Create test helpers to reduce boilerplate

# Test structure
- before test, initialize node and lossless view
- when test begins, create and ingest a series of deltas
- instantiate a resolver, in this case using custom resolver plugins
- call the resolver's initializer with the view
- call the resolver's reducer with the view
- call the resolver's resolver with the view
- expect the resolver to return the expected result
# Follow-up
- why isn't the resolver being called automatically, by event dispatch?
- we can prepare an array of deltas and pass it to a test helper,
- So our entire test case should consist of the deltas, the resolver, and the expected result.

# Test Helpers
This document provides documentation for the test helper functions available in the Rhizome Node test suite.
## `testResolverWithPlugins`
A helper function for testing custom resolvers with plugins and a sequence of deltas.
### Import
```typescript
import { testResolverWithPlugins, createTestDelta } from '@test-helpers/resolver-test-helper';
```
### Signature
```typescript
function testResolverWithPlugins<T>({
entityId,
plugins,
deltas,
expectedResult
}: {
entityId: string;
plugins: Record<string, ResolverPlugin>;
deltas: Delta[];
expectedResult: (result: T) => void;
}): Promise<void>;
```
### Parameters
- `entityId`: The ID of the entity to test
- `plugins`: An object mapping property names to their respective resolver plugins
- `deltas`: An array of `Delta` objects to process
- `expectedResult`: A callback function that receives the resolved result for assertions
### Return Value
A promise that resolves when the test is complete.
### Example Usage
```typescript
import { testResolverWithPlugins, createTestDelta } from '@test-helpers/resolver-test-helper';
import { ConcatenationPlugin } from '@src/views/resolvers/custom-resolvers/builtin-plugins';
describe('MyCustomResolver', () => {
test('should process deltas correctly', async () => {
// Run test with plugins and deltas
await testResolverWithPlugins({
entityId: 'entity1',
plugins: {
myProperty: new ConcatenationPlugin()
},
deltas: [
createTestDelta('user1', 'host1')
.setProperty('entity1', 'myProperty', 'value1')
.buildV1(),
createTestDelta('user1', 'host1')
.setProperty('entity1', 'myProperty', 'value2')
.buildV1()
],
expectedResult: (result) => {
expect(result.properties.myProperty).toBe('value1 value2');
}
});
});
});
```
## `createTestDelta`
A helper function for creating test deltas with a fluent API.
### Example Usage
```typescript
const delta = createTestDelta('user1', 'host1')
.withTimestamp(1000)
.setProperty('entity1', 'tags', 'red', 'color1')
.buildV1();
```
## How It Works
1. Creates a new `Lossless` instance for the test
2. Sets up a `CustomResolver` with the provided plugins
3. Ingests all provided deltas into the `Lossless` instance
4. Retrieves a view for the specified entity
5. Processes the view through the resolver
6. Calls the `expectedResult` callback with the resolved entity
## Best Practices
- Use this helper when testing custom resolvers with plugins
- The helper handles all setup and teardown of test resources
- Use `createTestDelta` for consistent delta creation in tests
- The helper ensures type safety between the resolver and the expected result type
- Each test gets a fresh `Lossless` instance automatically
