Using signals in render template should automatically apply to component #517
Description
The closest I'm seeing is this example, but it has some issues:
- Only
modelcan be updated, which would require us to change our components frominputfor anything we want to test, which is not ideal - Manually interacting with the underlying values like that is testing implementation details
- The template syntax in
renderdoesn't expose an underlying componentRef to callsetInputon
In an ideal world, the template will automatically update when the signal changes, like we'd expect in angular template HTML:
Preferred API:
it("should render text from a signal", async () => {
const someSignal = signal("hello");
await render(
html`<span data-testid="value">{{ someSignal() }} world</span>`,
{
componentProperties: {
someSignal,
},
},
);
// Passes
expect(screen.getByTestId("value")).toHaveTextContent("hello world");
someSignal.set("updated");
// Fails
expect(screen.getByTestId("value")).toHaveTextContent("updated world");
});
