Summary:

With the first fix attempts, the typing issue reproduced 2-3 times in 60 executions.
The current fix passed 500x in a row

Also, I've discussed this with @jgowdyelastic and we consider this a temporary fix until we find a way to make the job wizard input elements more stable for the automated typing.

+              }
+            });
+          });
+        }


I'm not sure if this solution will be effective and stable:

if the problem is that the letter may not be typed, it makes sense to reimplement WebElementWrapper: type function for ML tests. Wrapping existing code with 2 retries will slow things down and an additional check will not give a benefit if the wrong letter or in the letter is typed in the wrong order.

if the problem is that the field may be cleared during typing I suggest checking how the component re-rendering is triggered. Wrapping things with double retry will most like hide an issue the real user can face.

But 500 passing tests means the opposite :)

@dmlemeshko thanks for the feedback!
Some explanations to this approach:

We're already investigating the component and will (hopefully) fix it as soon as we know why it behaves that way, so this PR is only a temporary solution to fix typing until then (this is the 1st reason why I've implemented this as a separate method).

The slowdown due to retries is expected. I've called the method setValueWithChecks to set the right expectations: when I cal something WithChecks, I expect it to be slower (2nd reason for a separate method).

I agree that the outer retry is probably not needed (but I think the same holds true for the setValue method). This will just retry the whole thing in case an error is thrown on the way, so it doesn't really hurt. For the inner retries:

The first block will retry to clear the field

The second block does basically the following:
a. Type in the next character
b. Check if it was appended to the input value (give it 1 second time to appear there)
c. If it doesn't appear, try again, starting with step a. (retry for 5 seconds, then fail)

So I agree that it doesn't help to fix wrong letters or wrong order of letters. But that was not the scope of this fix, it should only check for missing letters.

I can see how this new method setValueWithChecks is very specialized to (hopefully temporarily) fix a specific issue and might not be appropriate for the testSubjects service. Happy to move it to a ML specific location if you think that's better.

@pheyos thank you for explaining the issue, it makes more sense now. Since you mentioned it is a temporary fix for ML-specific components, I suggest we don't put it in testSubjects.ts: we probably don't want other teams to start using it?

@dmlemeshko agreed. I've moved the method to a common ML service in a11a340 .

x-pack/test/functional/services/machine_learning/job_wizard_common.ts

 import { MachineLearningCustomUrlsProvider } from './custom_urls';

 export function MachineLearningJobWizardCommonProvider(
  { getService }: FtrProviderContext,
+  mlCommon: ProvidedType<typeof MachineLearningCommonProvider>,


In the future, I usually like to export this type from the module containing the provider so I can just import the MlCommon type without having to use these long types everywhere.

in common.ts

export type MlCommon = ProvidedType<typeof MachineLearningCommonProvider>

in here

import { MlCommon } from './common'

Good idea! I've created a PR for this: #52612
