help(ComponentHarness): TestElement.sendKeys() on disabled inputs

[alvaromartmart]

What are you trying to do?

I expect TestElement.sendKeys to respect the disabled status of input elements, however they don't seem to. The input is properly disabled on the application, the harness properly detects its disabled status... but sendKeys seems to bypass it.

Maybe I misunderstood something, any help would be appreciated.

What troubleshooting steps have you tried?

I tried running extra change detection cycles, etc. to no avail.

Reproduction

Steps to reproduce:

1. In the Stackblitz demo below, the test CustomInputHarness > should not fill disabled input should pass

https://stackblitz.com/edit/node-g4jhab?file=harness-sendkeys-demo/src/app/custom-input-component/custom-input-component.harness.ts

Environment

• Angular: 14.2, 15.1
• CDK/Material: 14.2, 15.1
• Browser(s): Chrome, though doesn't seem relevant
• Operating System (e.g. Windows, macOS, Ubuntu): macOS, though doesn't seem relevant

We can't do this across all the environments we support (TestBed, Protractor and WebDriver), because the e2e testing framework won't send keyboard events to disabled elements. We could make it work on TestBed, but then the behavior will be inconsistent.
