Release Note

e2e test coverage for toleration trait

[astefanutti]

I created https://github.com/apache/camel-k/pull/2123/files#diff-c5088002fef267f74c89b31c5472e9782c2cca9dc3e2e1b354c85d9553b1a042 few days ago.

I've tried to cover a real use, rather than artificial ones, that are already covered by unit tests. However this proves bit challenging as this requires a mutli-nodes cluster. I'm happy to drop my changes in favour of this version.

[tplevko]

@astefanutti I agree that this version might feel a bit artificial and the test you provided corresponds more with the e2e testsuite objective. I think it will be better to go with your changes and we can close this one.

[tplevko]

@astefanutti also there is also one more option - I can add these tests to the one you added. To increase the coverage. WDYT?

[astefanutti]

@tplevko that's a good idea 👍🏼. We can merge your PR since it's ready, and I'll merge mine into it. Does that work for you?

[tplevko]

@astefanutti sounds good to me!

[astefanutti]

@tplevko thanks. Let me merge it. Yaks tests errors are unrelated.

[astefanutti]

Thanks.
