jest issue - read to end of issue; perhaps related to resolveTypeReferenceDirectives addition?

Expected Behaviour

Build Successfully with no error

Actual Behaviour

I'm working with webpack + typescript + gulp, and loading .ts and .tsx files with ts-loader.
For most of the time, everything works fine.
But build RANDOMLY failed on ts2304 error or ts2345.
I found out that if I don't install types/jest (ts2304: cannot find describe ...etc.) and types/es6-shim (ts2345: something caused by promise I guess), I can always create the exact same build failure.

I added logs for npm install and ensured that the two types packages are installed successfully when build fails on this error.

So now I guess, it's probably caused by typescript not picking up those two typings? Or some ts-loader related issue?

Steps to Reproduce the Problem

I don't actually know how to reproduce it.

I already investigated on it for a month.... Really want to know what is happening here....

Many thanks!!!

Anyone can take a look?

[johnnyreilly]

I don't think anyone can as you haven't provided a minimal reproduction repo ...

I am experiencing a similar issue with a recent upgrade from 5.3.3 to 5.4.3.

As I build my project, I receive errors such as:

ERROR in /Users/moustachiste/work/frontend/public/tests/utils/url.test.ts
[tsl] ERROR in  /Users/moustachiste/work/frontend/public/tests/utils/url.test.ts(52,7)
      TS2582: Cannot find name 'it'. Do you need to install type definitions for a test runner? Try `npm i @types/jest` or `npm i @types/mocha`.

ERROR in  /Users/moustachiste/work/frontend/public/tests/utils/url.test.ts
[tsl] ERROR in  /Users/moustachiste/work/frontend/public/tests/utils/url.test.ts(61,9)
      TS2304: Cannot find name 'expect'.

I had no issue previously.

This is my tsconfig.json:

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "noImplicitAny": false,
    "target": "es6",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "moduleResolution": "node",
    "baseUrl": "src",
    "module": "commonjs",
    "resolveJsonModule": true,
    "esModuleInterop": true,
    "sourceMap": true,
    "skipLibCheck": true
  },
  "compileOnSave": false,
  "exclude": [
    "node_modules",
    "tests"
  ]
}

It seems to ignore the excluded folder tests. I have upgraded @types/[email protected], [email protected], [email protected], [email protected], to no avail.

If I exclude **/*.test.ts, it stops failing on those files (properly excludes I assume), but then I have a couple of other typescript files that fail under the tests folder, ie:

ERROR in /Users/moustachiste/work/frontend/tests/jest-framework.config.ts
[tsl] ERROR in /Users/moustachiste/work/frontend/tests/jest-framework.config.ts(10,1)
      TS2304: Cannot find name 'jest'.

A bit at a loss here.

EDIT: I guess I could try and hammer it to silence, but I think it'd be better to properly fix this problem.

EDIT2:
I changed the exclude property in tsconfig

"exclude": [
    "node_modules",
    "**/*.test.ts",
    "tests"
  ]

And while that silenced the error from jest-framework.config.ts above, this file still fails 🤔:

ERROR in /Users/moustachiste/work/frontend/public/tests/test__helpers/locationMock.ts
[tsl] ERROR in /Users/moustachiste/work/frontend/public/tests/test__helpers/locationMock.ts(25,3)
      TS2304: Cannot find name 'afterEach'.

I have a similar problem after updating from 5.3.3 to 5.4.4 (5.4.3 has same problem):

"TS2582: Cannot find name 'test'. Do you need to install type definitions for a test runner? Try npm i @types/jest or npm i @types/mocha."

I use jest, and jest itself runs fine. Webpack build fails. Downgrading only the ts-loader to 5.3.3 is my current workaround. My configs:

webpack.config.js:

            {
                test: /\.(tsx|ts)$/,
                loaders: [
                    "babel-loader",
                    "ts-loader",
                ],
            },

tsconfig.json

{
  "compilerOptions": {
    "target": "esnext",
    "module": "esnext",
    "moduleResolution": "node",
    "esModuleInterop": true,
    "noImplicitAny": true,
    "removeComments": false,
    "preserveConstEnums": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "forceConsistentCasingInFileNames": true,
    "resolveJsonModule": true,
    "baseUrl": "src",
    "sourceMap": true,
    "jsx": "react",
    "jsxFactory": "h"
  },
  "exclude": [
    "./node_modules"
  ]
}

Edit: I took a look at the sources and the history. It seems like the PnP feature is the reason. But i can not see what happens there: ea2fcf9

Edit2: Link to the merge request is #921

[johnnyreilly]

I would lay good money that this comes down to the addition of resolveTypeReferenceDirectives to the servicesHost.ts:

https://github.com/TypeStrong/ts-loader/pull/921/files#diff-70b0dbb6219cb6164e67ffb54a8f23c0R157

If someone could take a look at this and advise if there's a genuine problem with the way this is implemented that would be helpful.

It's difficult to take this further at the moment as we don't have a minimal reproduction repo to work with. Some assistance would be greatly appreciated; I'm fairly snowed right now ❤️

[craigsumner]

Ran into the same problem today, upgrading from 5.3.3 to 5.4.4.
Specifically, errors around failing to find types for jest test functions.

[xiaoouLi]

One thing to notice is that it happens RANDOMLY and very rarely...

[tjaskula]

Upgraded today from 5.3.3 to 6.0.0 and I have those problems too:

 [tsl] ERROR in common.test.ts(57,3)
          TS2582: Cannot find name 'it'. Do you need to install type definitions for a te

st runner? Try `npm i @types/jest` or `npm i @types/mocha`  and then add `jest` or `mocha

` to the types field in your tsconfig.

Adding jest to types filed in tsconfig changes nothing.

[KnisterPeter]

@johnnyreilly Here is a minimal testcase. It failes if you run yarn webpack-dev-server

KnisterPeter/ts-loader-minimal-jest-failure

[mijay]

I found a beautiful workaround. Just add the following to your ts-loader options:

resolveTypeReferenceDirective: function(directive, containingFile, compilerOptions, moduleResolutionHost, original) {
  return directive === "jest"
    ? { resolvedTypeReferenceDirective: { resolvedFileName: path.join(__dirname, "node_modules/@types/jest/index.d.ts") } }
    : original(directive, containingFile, compilerOptions, moduleResolutionHost);
}

[johnnyreilly]

Thanks for sharing the workaround @mijay

If someone else could take a look at this I'd appreciate it - I'm fairly busy right now.

Given the workaround just shared I suspect that any fix (should one be required) be applied to makeResolveTypeReferenceDirectives:

ts-loader/src/servicesHost.ts

Line 506 in cc7b2b1

function makeResolveTypeReferenceDirective(

I'd suggest debugging the resolveTypeReferenceDirectives could very much inform what we want to do here. Thanks to @andrewbranch there's some good instructions on debugging here: https://github.com/TypeStrong/ts-loader/blob/master/CONTRIBUTING.md#debugging

Though you may well be able to get what you need using console.log too 😁

However I haven't looked into this and others may know more than me 😄

As ever: PRs are welcome ❤️

[andrewbranch]

This is fixed in v6.0.1, which is building and publishing now.

[johnnyreilly]

Awesome work @andrewbranch!

[lemoustachiste]
