# 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
