Cannot read properties of undefined (reading 'item')

[jakeklassen]

Describe the bug
When leveraging test.each and running tests via the vscode extension I see this error:

TypeError: Cannot read properties of undefined (reading 'item')

The tests run just fine from the CLI.

To Reproduce
Steps to reproduce the behavior:

1. Clone https://github.com/jakeklassen/vitest-test-each-error
2. Install via pnpm i or npm i - I tested both
3. Run the tests from within visual studio code
4. See error

Expected behavior
The tests to pass just as they do in the CLI.

I'm getting the same error. When I run the sample project I get

I also don't get any info.txt, running node setup.mjs gives me:

Same here, I think this is related to having multiple tests using it.each or test.each and same issue even when doing [].forEach(x => it())

This code fails when I click "run" button in test explorer next to the "isWarning":

import { describe, expect, test } from "vitest";

describe("isWarning", () => {
  test.each([
    [
      "Uncaught ReferenceError: angular is not defined in https://bla.bla/assets/vendor/angularjs-dropdown-multiselect/angularjs-dropdown-multiselect.min.js at 3:143",
      true,
    ],
    ["Cannot find default tariff with bookId '587dbb6986234155bd506185' in library books of country NZ", false],
  ])(`returns %s for %s`, (errorMessage, expected) => {
    expect(true).toBe(true);
  });
});

This is log:

[INFO 15:45:05] Vitest api process finished
[Error 15:45:05] [Workspace "vue-elements] Run error
[INFO 15:45:05] [Workspace vue-elements] Error: TypeError: Cannot read properties of undefined (reading 'item')

[INFO 15:45:05] WS Close
[INFO 15:45:05]  ✓ src/__tests__/report-issue.spec.ts  (2 tests) 3ms

This is what I see when I click "run" button next to "returns %s for %s":

When I click "run" button next to the test file name - it doesn't show that error, but still shows test as not passed.

All I have to do to fix the issue is to use different test argument strings, this works fine:

import { describe, expect, test } from "vitest";

describe("isWarning", () => {
  test.each([
    ["a", true],
    ["b", false],
  ])(`returns %s for %s`, (errorMessage, expected) => {
    expect(true).toBe(true);
  });
});

and this doesn't:

import { describe, expect, test } from "vitest";

describe("isWarning", () => {
  test.each([
    ["angularjs-dropdown-multiselect/angularjs-dropdown-multiselect", true],
    ["b", false],
  ])(`returns %s for %s`, (errorMessage, expected) => {
    expect(true).toBe(true);
  });
});

I don't think it's because of the special characters, changing argument length seems to help, but that seems to be kinda random...

I also managed to do this:

Also all works fine in CLI.

would there be plans to address this issue later?
i'm getting same error, wish i could help solving the issue but error messages seem similar to me

Duplicate. Close in favor of #133

@scarf005, maybe you're interested in #133 . But it's not an easy fix
