This cleans up the triggering code base and consolidates it down to one
function that outlines the logic. This also resolves the `hydrate when`
behavior issue.
fixes: #58709
PR Close#58833
This commit addresses a problem with tests that use the `fit` function to focus on individual test cases. While these tests run successfully in the full suite, they fail when focused individually using `fit`.
The issue lies in the behavior of `withEventReply` and other hydration-related functions (i.e., `provideX`, `withX`). These functions return platform-specific providers based on the `ngServerMode` setting, causing inconsistencies between server and browser environments. As a result, provider instances cannot be reused across server and browser applications.
**Example of problematic code:**
```ts
const hydrationFeatures = [withEventReply()];
const html = await ssr(SimpleComponent, { hydrationFeatures });
// Expected behavior ...
const appRef = await prepareEnvironmentAndHydrate(doc, html, SimpleComponent, {
hydrationFeatures,
});
// Expected behavior ...
```
**Solution:**
To address this, we define `hydrationFeatures` as a function instead of a static array. This ensures that a new instance of `withEventReply` is created separately for each environment, eliminating platform-specific mismatches between server and browser contexts:
```typescript
const hydrationFeatures = () => [withEventReply()]; // Define as a function
const html = await ssr(SimpleComponent, { hydrationFeatures: hydrationFeatures() });
// Expected behavior ...
const appRef = await prepareEnvironmentAndHydrate(doc, html, SimpleComponent, {
hydrationFeatures: hydrationFeatures(),
});
// Expected behavior ...
```

This re-organizes the hydration tests to make it easier to add new tests. Incremental hydration can have tests in a separate file after this groundwork is landed.
