[Bug]: ESbuild fails to install and extension fails to extract tests

Checklist

I have read and agree to the Code of Conduct
I have searched for related issues and discussions but they did not match this problem.
I want to contribute a bugfix myself.

Actual behavior

Extension fails to install esbuild but continues, then finds test files but logs as error when trying to extract tests. No tests are able to run.

Expected behavior

Tests are found and are able to be run.

Minimal, Reproducible Example

Reproducible using the mocha-vscode-extension branch for my project:

Clone repo and checkout branch
(Optionally) open in devcontainer for best reproducibility
Enable extension
Observe extension output with Debug log level

Output

Output from the extension in the devcontainer. The same output is created when running locally on my host machine just with different npm version and parent paths.

Further details

On the host machine the extension is using node 22.8.0 found at /usr/bin/node but I use nvm and node 18.19.1 (specified in launch/settings.json). This shouldn't be a problem though since the same behavior occurs in the devcontainer when using the same node version and an official devcontainer image.

You can see the mocharc file in the repo but for brevity:

{
  "reporter": "dot",
  "extension": "ts",
  "import": "tsx/esm",
  "spec": "./src/backend/tests/**/*.test.ts"
}

I use tsx for running the application and running mocha tests npm run test without issue. Webstorm also has no issue parsing tests from mocha.

I had the same problem. It looks like optional dependencies (@esbuild/linux-x64 in this case) are not being installed when the extension is initially installed via VSCode. Not sure if something has changed there.

I got this extension to install properly & work by running npm i inside the extension folder itself after install. In the OP's case that would be in /home/node/.vscode-server/extensions/coderline.mocha-vscode-1.2.0. npm i complained about not being able to "cd to src/typings", but I ignored that and it still worked.

Finally it requires a reload of the VSCode window to reactivate the extension.

Hope this helps.

When the Extension launches it will install the dependencies according to the platform. This is what we see in the logs.

               }); 
        
             }); 
        
           }

From the logs I see the esbuild script attempts to install the package but then doesn't really report it being installed. esbuild does this npm installation here: https://github.com/evanw/esbuild/blob/d34e79e2a998c21bb71d57b92b0017ca11756912/lib/npm/node-install.ts#L118

I will need to try setting up a similar setup to troubleshoot. In the meanwhile you could try following to see if there are suspicious logs which help finding the problem:

Go to the Extension install directory (e.g. /home/node/.vscode-server/extensions/coderline.mocha-vscode-1.2.0/ as printed in the logs)
Try running the esbuild install script. Maybe there are some logs hidden and not forwarded by this extension:
1. cd /home/node/.vscode-server/extensions/coderline.mocha-vscode-1.2.0/node_modules/esbuild
2. /usr/local/share/nvm/current/bin/node install.js
Try installing the optional dependency manually. I'd expect some sort of info or error output.
1. cd /home/node/.vscode-server/extensions/coderline.mocha-vscode-1.2.0/
2. npm install --prefer-offline --no-audit @esbuild/linux-x64@0.24.0

Running the esbuild script (2) produces the same output as from my OP ([esbuild] Failed to find package "@esbuild/linux-x64" on the file system) without any additional logging that would be helpful.

I was able to install it successfully using (3) at which point (2) causes no errors to output.

Using the extension at this point does not spit out the same errors but tests are still unable to be extracted:

I switched to using mcr.microsoft.com/devcontainers/javascript-node:1-18-bookworm so that NVM is no longer used in the container:

Same results though.

Seems the install.js of ESBuild is rather broken. It attempts to download and install the platform specific dependency, but the paths where they are then placed are wrong leading to execution errors.

The "extraction" error is rather a code execution problem in multi-scrobbler. mocha-vscode attempts to mock all imports to the project and then fake-execute the test file to discover the tests contained.

In multi-scrobbler the code above the actual tests leads to an error: chai.use. The problems are on multiple levels:

In the import import chai, { assert, expect} from 'chai' the chai import is undefined.
Changing it to the following code still shows chai as undefined.

import chai from 'chai';
chai.use(asPromised);
const assert = chai.assert;
const expect = chai.expect;

Changing it to the following code complains that use is not a function as we mock things to objects.

import * as chai from 'chai';
chai.use(asPromised);
const assert = chai.assert;
const expect = chai.expect;

To fix these problems we need two fixes:

Default imports need mocking.
We need to extend the Proxy to be callable. The apply trap should work.

@FoxxMD I released a 1.2.1 patch with all improvements. Can you give them a try in your setup (once the update becomes available)? IN my test setup things worked as expected.

If you have more advanced logic across imports which actually need execution of the files including their dependencies, you could switch your project settings to evaluation-cjs-full. This way no "mocking" of the imports happen (at the cost of performance).

	// ESBuild needs the platform specific binary for execution
	// here we run the init script coming with ESBuild
	async function initESBuild(context: vscode.ExtensionContext, logChannel: vscode.LogOutputChannel) {
	logChannel.debug('Installing ESBuild binary');

	const node = await getPathToNode(logChannel);
	const cli = await new Promise<ChildProcessWithoutNullStreams>((resolve, reject) => {
	const p = spawn(node, ['install.js'], {
	cwd: path.join(context.extensionPath, 'node_modules', 'esbuild'),
	env: {
	...process.env,
	ELECTRON_RUN_AS_NODE: '1',
	},
	windowsHide: true,
	});
	p.on('spawn', () => resolve(p));
	p.on('error', reject);
	});

	cli.stderr.pipe(split2()).on('data', (l) => {
	logChannel.debug('[ESBuild-stderr]', l);
	});
	cli.stdout.pipe(split2()).on('data', (l) => {
	logChannel.debug('[ESBuild-stdout]', l);
	});

	await new Promise<void>((resolve, reject) => {
	cli.on('error', reject);
	cli.on('exit', (code) => {
	if (code === 0) {
	logChannel.debug(`Installing ESBuild binary exited with code ${code}`);
	} else {
	logChannel.error(`Installing ESBuild binary exited with code ${code}`);
	}
	resolve();
	});
	});
	}
