Created --notifyMode option for notifications on certain events #5125

psilospore · 2017-12-18T23:39:15Z

Summary

I would like notifications only on failure. It seems that someone else wanted something similar: #1839

Test plan

Unfortunately I'm not able to run yarn test. I end up with this error:

Error: packages/jest-circus/src/format_node_assert_errors.js:10
 10: import type {DiffOptions} from 'jest-diff/src/diff_strings.js';
                                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ jest-diff/src/diff_strings.js. Required module not found

Also yarn install didn't work for me. I used npm install instead since I got this error:
error An unexpected error occurred: "https://registry.yarnpkg.com/@babel/code-frame/-/code-frame-7.0.0-beta.35.tgz: Request failed \"404 Not Found\"".

I followed the the contribution guide as well https://github.com/facebook/jest/blob/master/CONTRIBUTING.md

Updated Test Plan

run yarn jest --watch --notify --notifyMode=failure examples with the various notifyMode options.
success, always, failure, and change

Modify examples/snapshot/tests/link.react.test.js and check if notifications appear when appropriate.

You need to use yarn as we use yarn workspaces in this repo. Not sure about your error, the URL in you comment (https://registry.yarnpkg.com/@babel/code-frame/-/code-frame-7.0.0-beta.35.tgz) resolves for me. Can you try again, making sure you are on 1.3.2 of yarn?

Also, this needs some sort of test to illustrate it's working (although I understand it's hard to add a test when you're unable to install the repo)

@SimenB I understand I was hoping someone would happen to know how to fix this when I made the PR, and I would be able to quickly update my PR. It seems that updating yarn fixed my second issue, and running yarn add -W jest-diff as a workaround fixed my second issue.

I have a few issues now that it's running and I will try to update the PR soon. Thank you!

I'm not sure we want this to overload. Maybe a separate notify-mode or something? Changing its type is a breaking change, and would mean we couldn't merge this PR for months

Something like what travis gives you, where you can get a notification on failure, and when that turns green, but not green after one another. (https://docs.travis-ci.com/user/notifications/#Changing-notification-frequency)

The you could have onFailure, onSuccess, onChange. for instance.

That sounds like a better design. I like the additional events travis has as well. I'll try to spend some time tonight.

That was it 🥇 still have to work on the change option though. It seems like a new instance of NotifyReporter is created every time jest --watch reruns. I'll look into that.

Let me know what you think of this. I wasn't sure what the best practice for updating the state from my previous run in NotifyReporter would be.

The NotifyReporter can have local state, can't it? Why not just have this._firstRun = false etc in there?

run_jest seems to create a new instance of TestScheduler every time a file changes with --watch and TestScheduler creates a new instance of NotifyReporter.

docs/Configuration.md

+* `always`: always send a notification.
+* `failure`: send a notification when tests fail.
+* `success`: send a notification when tests pass.
+* `change`: send a notification when the status changed.


It's missing the mode I would use, which is "on every failure, and change to success". I want a notification that my tests are still red on every run until they're green, and when it turns green, but not on every run when it's green. I'm not sure how to best express it, though. Travis has onSuccess and onFailure with different modes, but it feels a bit overkill to add two new options.

What about: always, failure, success, change, failure-always, failure-change, success-always, success-change, and allow notifyMode to be passed an array instead of a single string?

I'm not sure if that's the best option, it's just what I could come up with without thinking too much about it

What would be the difference between failure-always and failure (same with success and success-always)? I personally would prefer keeping it a string because I can only imagine 2 cases from the current combination of options. e.g. ['failure', 'change'] to accomplish the case you mentioned, and I think it would be better expressed as a string with failure-change

success-change would accomplish the inverse.

What would be the difference between failure-always and failure

Good point, those would be the same. failure, success, always, change, failure-change and success-change works for me

Just added those :)

why is this needed?

eslint didn't seem to recognize that this will be mutated in NotifyReporter

You mutate the content, not the variable itself, can't this be const?

Yeah, there's no true native immutability in JS :(
