fix(cdk/testing): require at least one argument for locator functions by crisbeto · Pull Request #23619 · angular/components

crisbeto · 2021-09-22T20:10:21Z

Currently locator functions accept a spread argument which technically allows for zero selectors to be passed in. This can result in weird runtime errors.

These changes add a runtime error if no selectors are passed in.

Note that a previous iteration of these changes tried to enforce this with typings, but it resulted in breaking changes.

 ComponentHarnessConstructor<T> | HarnessPredicate<T>;

+/** Queries that can be passed into a locator function. */
+export type LocatorQueries = [HarnessQuery<any> | string, ...(HarnessQuery<any> | string)[]];


I'm not a fan of the name, but I couldn't come up with something better. I also don't want to do it inline since it's a little long.

I looked into the g3 failures for this PR and they are all caused by the fact that the new method signature doesn't allow for the spread operator to be used. E.g. there is code like:

locatorFactory.locatorForAll(...arrayOfPredicates);

Which causes this error:

A spread argument must either have a tuple type or be passed to a rest parameter. ts(2556)

I tried a few alternate approaches like moving the spread argument to the front of LocatorQueries, but it didn't help.

Should we just change this to a runtime error, then?

Changed to a runtime error in order to unblock it.
