Looking at our resolution in #32, I'm going to assume we're still using babel-register. I have a feeling that there is no stack trace because there is no stack to dump (i.e. it's only 1 level deep)
The error looks like it's coming from the Babel transpiler reading in /Users/joepea/src/trusktr+infamous/src/html/behaviors/Behavior.js, it's not an error from Electron running the file -- but when it transpiles it instead
For reference, here's what a normal runtime error stacktrace looks like:
Electron 1.8.8 (Node 8.2.1) module for `require` based Node.js integrations in the top level identify as the page itself FAILED
Error: Test error

@twolfson Alright, I've done some debugging. I've found out that the errors are being thrown from within the require() calls that I have in the @babel/register setup.
However, the stack traces are deep, and I can see the stack traces if I modify the code to catch them and log them manually.
Here's that part of my karma config.
I modified that part of my karma config so it looks like the following:
testFiles.forEach(file => {
const relativeFile = file.replace(CWD, '')
const relativePath = dirname(relativeFile)
mkdirp.sync( CWD + '/.karma-test-build' + relativePath )
const nodeModulesToCompile = config.nodeModulesToCompile
fs.writeFileSync( CWD + '/.karma-test-build' + relativeFile, `
// NOTE, we don't use babel.config.js settings here, we can target a
// more modern environment.
require('@babel/register')({
presets: [ ['@babel/preset-env', { targets: { node: 9 } }] ],
plugins: [
// We need to transpile the not-yet-official re-export syntax.
'@babel/plugin-proposal-export-namespace-from',
'@babel/plugin-proposal-export-default-from',
],
sourceMap: 'inline',
${config.nodeModulesToCompile ? `
ignore: [
// don't compile node_modules except for ones specified in the config
${nodeModulesToCompile.map(moduleName => {
return r`/node_modules(?!\/${r.escape(moduleName)}\/)/`
})}
],
` : ''}
})
// RIGHT HERE, LOG THE ERROR ----------------------------
try {
require( '${ file }' )
} catch(e) {
console.log(e)
process.exit()
}
` )
})Before doing this, I was seeing an error like:
Electron 2.0.18 (Node 8.9.3) ERROR
{
"message": "Uncaught TypeError: Cannot read property 'default' of undefined\nat /Users/trusktr/src/trusktr+infamous/src/core/ImperativeBase.js:100:129\n\nundefined",
"str": "Uncaught TypeError: Cannot read property 'default' of undefined\nat /Users/trusktr/src/trusktr+infamous/src/core/ImperativeBase.js:100:129\n\nundefined"
}
Then after adding the try-catch and logging the error I was able to see:
Electron 2.0.18 (Node 8.9.3) LOG: TypeError: Cannot read property 'default' of undefined

at Object.<anonymous> (/Users/trusktr/src/trusktr+infamous/src/core/Motor.js:15:86)
So my question is, if I don't catch the error and log it my self, what in the stack is deciding to display such a limited version of the error?

Seems like something in karma or karma-electron is choosing not to log the full error output?

I can't think of anything off the top of my head. Pretty confident it's
either Karma or your repo since we do nothing to tweak errors in
karma-electron
Easiest way to find out would be to try another Karma engine (would
disqualify/prove karma-electron) and use a simpler repo (would
disqualify/prove your repo)

Alright, after disabling karma-electron, and using default values for the browser,
karma.config.js
module.exports = function(config) {
config.set({
frameworks: ['jasmine', 'stacktrace'],
port: 9876, // karma web server port
colors: true,
logLevel: config.LOG_INFO,
autoWatch: false,
singleRun: debugMode ? false : true,
concurrency: Infinity,
basePath: CWD,
files: [
'tests/**/*.js',
],
client: {
useIframe: false,
loadScriptsViaRequire: true,
},
})
}the errors are still in the same format. So for this simple test file,
test file
console.log( 'test.js' )
throw new Error('test error')
describe('Tests...', () => {
it('needs to be implemented', () => {
expect(true).toBe(true)
})
})the error output is in the same format, but they are now tagged with Chrome instead of Electron:
error output:
09 04 2019 19:26:37.163:INFO [karma-server]: Karma v4.0.1 server started at http://0.0.0.0:9876/

"str": "An error was thrown in afterAll\nError: test error\n at tests/test.js:3:7"
}
Longer errors can be even worse:

}
So it seems like it is something to do with Karma.
