chore: add SSR tests (test command)

[layershifter]

New Behavior

This PR finished implementation of #22788 and adds test command:

$ yarn test
Starting a browser...
Using HeadlessChrome/103.0.5058.0
Using "file://apps/ssr-tests-v9/dist/index.html"
Test finished successfully in 2.26s

The command uses assets that were built with build command, runs them in a browser and checks console.

If test fails it will emit an error:

I don't mind but I am curious why you get that error ? I tried it out myself in one of react-menu test files

[layershifter]

• ts-node-register ignores local configs and uses own
  

  fluentui/scripts/ts-node-register.js

  Lines 14 to 17 in 49c53f4

  	compilerOptions: {
  	...readConfig(path.join(__dirname, 'typescript/tsconfig.common.json')).compilerOptions,
  	...readConfig(path.join(__dirname, 'tsconfig.json')).compilerOptions,
  	},

• the second config has esModuleInterop that causes the problem
  

  fluentui/scripts/tsconfig.json

  Line 8 in 49c53f4

  "esModuleInterop": true,

[Hotell]

ideal would be if we can follow same patterns (especially in module resolution area ) as it might bit us whenever 2 different packages needs to be used together ?

I'd recommend to not use that ts-node-register as it parts its ways in terms of setup for v9 related code.

Can we use rather ts-node directly for invocation and provide local tsconfig.lib.json + remove allowSyntheticDefaultImports ?

WDYT?

[layershifter]

@Hotell did I correctly understand your suggestion (d106951)?

[Hotell]

yes !

[Hotell]

great stuff ! added some comments/suggestions

[Hotell]

thought: for better DX, can we maybe initiate the build for the user with proper notification what's going on and re-run the test ?

[Hotell]

"inheritance" in JS is a confusing paradigm that doesn't work as one might think it works. with that leveraging instanceof is potentialy dangeours operation as it wont give you similar guarantees like in true OO languagues.

for those reason I'd recommend if we could follow one of following patterns:

1. dont use "extends" rather literal objects

error = { message: message.text(), name: 'RenderError' };


// later on

  if (err.name === 'RenderError') {

2. properly instantiate name of custom error

class RenderError extends Error {
  name = 'RangeError'
}

// check will be the same as in 1st option = no instanceof

WDYT ?

[ling1726]

curious, what is wrong with instanceof in this case?

[layershifter]

@Hotell I added name 9c37647, but I am confused as @ling1726. What is wrong with instanceof? 🤔

[Hotell]

in this particular case there is nothing wrong.

To give you better context:

from experience I avoid "volatile" JS lang features in general, which besides various JS quirks is also "OOP features", thus duck typing is always an obvious choice.

• doesn't work with objects that are shared between windows/frames (not our case)
• problematic with isArray / http://perfectionkills.com/instanceof-considered-harmful-or-how-to-write-a-robust-isarray/
• if target output is es5 (not our case) this will not work

[Hotell]

no need for public as everything is public by default. TS class accessors is a "lie" in general

[layershifter]

I added because it's enforced by ESLint rule...
