Failure to run test

[ekoulemaneng]

Current Behavior

When I run yarn test, I get this bug:

` FAIL test/blah.test.ts ● Test suite failed to run

TypeError: The "path" argument must be of type string. Received undefined

  at ScriptTransformer.transformSource (node_modules/@jest/transform/build/ScriptTransformer.js:481:35)`

Expected behavior

And yet, I have only tested the function of the basic boilerplate of TSDX.

I don't know the direct fix, but as a workaround you could use dts-cli which is a maintained fork of tsdx, or try downgrading to TypeScript v4

I have got the same issue, and really I don't like to downgrade anything. still I'm seeking for a solution.

@jaredpalmer, Could you take a look please?

I got same issue, and I just use command npx tsdx create mylib2 initial the project. the following is the error message.

D:\Projects\mylib2  (mylib2@0.1.0)

So I wasn't able to directly fix the issue but my workaround for not having to downgrade my typescript version was to install ts-jest and jest directly using

yarn add --dev jest
yarn add --dev ts-jest
yarn add --dev @jest/globals

so now my devDependencies look like this

  "devDependencies": {    
    "@jest/globals": "^29.5.0",
    "@size-limit/preset-small-lib": "^8.2.4",
    "@types/jest": "^29.5.1",
    "husky": "^8.0.3",
    "jest": "^29.5.0",
    "size-limit": "^8.2.4",
    "ts-jest": "^29.1.0",
    "tsdx": "^0.14.1",
    "tslib": "^2.5.0",
    "typescript": "^5.0.4"
  },

then I changed my "test" script to run "jest" instead of "tsdx test"

  "scripts": {
    "start": "tsdx watch",
    "build": "tsdx build",
    "test": "jest",
    "lint": "tsdx lint",
    "prepare": "tsdx build",
    "size": "size-limit",
    "analyze": "size-limit --why"
  },

my test file looks like this now

import {describe, expect, test} from '@jest/globals';
import {sum} from './sum';

describe('sum module', () => {
  test('adds 1 + 2 to equal 3', () => {
    expect(sum(1, 2)).toBe(3);
  });
});

I'm pretty sure the "@jest/globals" isn't actually needed because of having "@types/jest" installed but I don't feel like messing with this any further.

edit:

I forgot to mention I also ran yarn ts-jest config:init

@Connor-8 Hi. Thank you. Where did you run yarn ts-jest config:init?

@Connor-8 Hi. Thank you. Where did you run yarn ts-jest config:init?

If I remember correctly (emphasis on the "if I remember") it was in the root my project in order to generate the jest.config.js so if you already have one it might not be necessary.

[ApayRus]

@Connor-8 thank you :) I gave up and downgraded typescript to v4 :smile:
