Unfortunately, the tests are still failing locally (which is the case since fdd7c41).
I verified by running the suite 3 times using npx run test @theia/example-browser.

I am running on Linux (Ubuntu 18.04), but it is also reproducible on Gitpod (which uses Ubuntu 20.04 LTS) when executing the tests.

@vince-fugnitto Could it be that your machine is slow and preparing plugin views takes longer? Gitpod can hit noisy neighbourhood problem then everything is slow. Try to increase timeout and see whether issue is gone or share the output of failed timeouts.

I increased the timeout for both to 14000 and it still fails locally. I noticed the following errors:

Your errors are very different, not about timeouts. How do you run test? yarn test or yarn test:debug. In the second case you should make sure to keep the page in focus. Could you try from the clean setup?

I either do:

npx run test @theia/example-browser

or

(cd exampes/browser && yarn test)

Both of them fail similarly, is there a specific way I should run the tests?

I ran several times in Gitpod and got once:

I've restarted Travis again to see whether it will fail.

Yes, else they'd fail on a timeout for the explorer mainly.

I tested this a bit. I still got the occasional failure with both timeouts set at 30000 but it passes most of the time. With the timeout at 7500 I get similar results as @lmcbout - about 50% success.

@akosyakov in these tests, is an actual browser used? Is data stored in local storage cleared between runs?

How do you get that? Timeout is 7500ms, not 2000ms. Are you sure you are testing against this PR?

If you do yarn test then it should be a clean browser each time.

I suggest we merge this PR to fix travis. One has to dive in the rest of errors. It does not seem that Theia behaves the same for all operating systems and machines. I will remove fix marker from the commit message to indicate it.

Do you know why in your case the tests use typescript 3.9.2? Do you have it globally installed?

It is one which should be installed: https://github.com/eclipse-theia/theia/blob/master/package.json#L39 built-ins should be configured to use the workspace version:

"typescript.tsdk": "node_modules/typescript/lib",

I suspect something in your workspace storage under user settings telling buil-in extension to ignore the project settings.

@akosyakov do you perhaps have the preference value set at the user level (reason for why it is picked up).
Based on the description of the preference, when the preference is set at the user level it will replace the builtin version from the extension:

Screenshot from 2020-07-13 10-27-47

I suspect it may be the reason that different users experience different results when running the suite.
When I did set the preference at the user level as well the tests were much more stable.

I found the typescript version can also be set globally in another way. The built-in typescript-language-features creates a memento when the user selects which typescript to use (VS Code's or Workspace's) through the Select TypeScript Version command (can be triggered from typescript version on status bar).

That memento is saved in user storage, under workspace-storage. e.g. /home/user/.theia/workspace-storage. File name: workspace-state.json (there may be more than one, for other purposes). Here's what the right one looks like:

{"vscode.typescript-language-features":{"typescript.useWorkspaceTsdk":true}}

@marcdumais-work

I found the typescript version can also be set globally in another way.

In fact I am not totally sure this setting is global. The memento are in subdirectories that have hash-like names, and might be the hashed workspace, for all I know. But in any case I think the setting at least sticks for the workspace it was set.

@marcdumais-work
Copy link
Contributor

@akosyakov Maybe stupid question, but is there an unstated assumption that one should explicitly select "Use Workspace Version" for TypeScript, at least once? Because once I do this, the setting sticks, but I can't seem to trigger the workspace TypeScript being used otherwise.

Or are the workspace configs supposed to be enough for this to happen automatically?

P.S.. on Gitpod too, TypeScript 3.8.3 is used for me ATM, when I launch the example application built from this PR.

I will need to read the code of the extension again. I am not sure that what is stored in the memento actually affecting the resolution and does not only affect how the quick pick is decorated.

I'm wrong tests are running from examples/browser folder, so 3.8.3 is the proper version. Deleting .theia folder from a user home helps, but it is not typescript settings in the workspace storage causing issue, something else.

@akosyakov One little thing I noticed: since these tests open folder examples/browser as workspace, a .theia folder is created there that may contain state. It's invisible to git status because we exclude this in root .gitignore.

No, I was just thinking this state left behind by the suite is a potential source of entropy, that could make the tests behave differently the second time run in an environment and beyond.

@marcdumais-work
Copy link
Contributor

I noticed another potential source of entropy, when running the test suite locally: the test suite uses default port 3000 for its Theia backend(s). Theia developers can be expected to use that port a lot locally, and sometimes may have one or more forgotten browser tabs, patiently waiting for a Theia app to start serving that port. What if one or more of these is connected at the same time as the test's driver?

I tried to test this locally, and my "extra" frontend ends-up waiting for user input:

I noticed another potential source of entropy, when running the test suite locally: the test suite uses default port 3000 for its Theia backend(s).

BTW this is made much less bad now, that the tests do not re-use the user-storage folder (~/.theia). Before that, ~/.theia/recent-workspace.json would make is so that a newly started frontend would re-use the same workspace as the tests, increasing much the risks of conflicts. 👍

I've pushed another commit which ensures that a new temp directory is used for user data on each new run of yarn test. Could you try again please?

Running locally, the tests now pass a great majority of the time, maybe ~90%. Much improved - thanks @akosyakov !

@marcdumais-work You are right there can be other reasons for entropy, but i think we can address them as they come up.

I tried to test this locally, and my "extra" frontend ends-up waiting for user input:

It should be resolved by #7908 It handles user triggered file changes and external differently, so it won't block anymore another window.

LGTM - tests now pass locally much more frequently than before. As suggested, let's start with this and we can further improve as we go.

One little thing I noticed: since these tests open folder examples/browser as workspace, a .theia folder is created there that may contain state. It's invisible to git status because we exclude this in root .gitignore.

I tried to look-for a correlation between keeping or deleting that workspace .theia folder and test failures, but I could not find any.
