jest + ts-jest: after 26.6.0/26.4.1, combination throws error "Cannot read property 'cwd' of undefined

[fluffynuts]

🐛 Bug Report

We've set our package versions for jest and ts-jest to x, so we always have the latest. We don't use a package-lock, and our CI always builds from scratch. Recently, builds were failing at the test phase with:

  ● Test suite failed to run
    TypeError: Cannot read property 'cwd' of undefined
      at new ConfigSet (node_modules/ts-jest/dist/config/config-set.js:144:59)
      at TsJestTransformer.createOrResolveTransformerCfg (node_modules/ts-jest/dist/ts-jest-transformer.js:95:38)
      at TsJestTransformer.getCacheKey (node_modules/ts-jest/dist/ts-jest-transformer.js:72:14)

using a tool I just wrote (time-walker, available on npmjs.com), I "traveled back in time" to find when things officially broke, which was 4 days ago, with versions:

jest: 26.6.1
ts-jest: 26.4.2

going back a day, things work fine with versions:
jest: 26.6.0
ts-jest: 26.4.1

For now, I'm going to pin at these versions, but I'd like to keep on the bleeding edge as soon as the issue can be properly resolved.

To Reproduce

• Install latest jest & ts-jest
• tests fail to run (this is in a Vue test environment, but I'd expect that Vue isn't the problem. I don't know if babel or anything else is involved, so I'm including our package.json (package is a private project, never mind about the name):

Expected behavior

Expected tests to run as they had done the day before. I know that jest and ts-jest don't follow semver, but the change is at a minor version, so breakage is unexpected.

Does clear cache help ? Can you please use 26.4.3 ?

[fluffynuts]

• cache is cleared on test every time because jest cache is often the cause of dodgy errors
• everything after 26.4.1 causes the issue -- we were getting it with 26.4.3 as well (and jest 26.6.1). I initially reported the first version at which the problem occurs, but have updated to include all versions where I've had problems.

[ahnpnl]

hmm I haven't seen this error before. Would you please provide a repo to reproduce this issue ?

[fluffynuts]

@ahnpnl I know it's super-annoying, but I can't provide our repo to do so -- it's private.

I'll see if I can conjure up a repo to repro -- if I can, I'll post here. I tried to debug, and found that the transform config was being sent through undefined, but that's about as far as I got before I started rather hunting for a workaround with package pinning so my team wasn't being held up any more.

[ahnpnl]

https://github.com/ahnpnl/ts-jest-only-example you can try to reproduce with this

[ahnpnl]

From the stack trace, for some reasons ConfigSet is initialized with undefined jest config. Not sure how and when that happens

[fluffynuts]

yeah, that's what I saw, tracing back a bit from the error text; I'm not sure if there's something specific to our environment which is helping to cause the problem.

thanks for the starter, but I was thinking about trying to cut out most of our project to get a reproduction, since I don't know what the cause is.

In the mean-time, you could diff 26.4.2 against 26.4.1 -- with the same version of jest (26.6.1), the latter works, where the former doesn't. Something has changed between 26.4.1 and 26.4.2 which introduces the issue, as far as I can tell.

[ahnpnl]

I tried with both Mac and Windows from my side but still no luck to reproduce the issue.

@fluffynuts would you please also include full stack trace ?

[fluffynuts]

I don't have any more of a trace than in the initial report. I haven't had the time yet to produce a proper repro repo either, sorry -- been helping people on my team. Trying to get time to do stuff is a mission )': But I have put it in my list of 💩 to get done

[ahnpnl]

Hi, is your issue resolved with 26.5.2 ?

[fluffynuts]

still happens with ts-jest@26.5.2 and jest@26.6.0 and jest@26.6.3

we've already had to pin ts-jest at 26.4.1 and I have also pinned jest at 26.6.0 although testing now, I see I can upgrade jest to latest (26.6.3)

[ahnpnl]

Would you please provide the stacktrace with 26.5.2 and ts-jest log as well ? :)

[fluffynuts]

sure, stack:

One thing looks strange to me is the logging keeps saying no config found which constantly triggered the line "no matching config-set found, creating a new one". Have you got any chances to create a reproduce repo ?

[fluffynuts]

I'll see if I can get some time - will most likely have to strip out from our existing repo. I'm quite sure it was created with vue-cli tools tho, if you want to give that a go in the mean-time.

[ahnpnl]

Ok I can use Vue-cli as a start. Would you please give me some sample test codes which I can use ?

[fluffynuts]

as far as i can tell, any test will cause the problem - even something as silly as:

it("should pass", () => {
   expect(1).toEqual(1);
});

since it doesn't seem to get to running any of the tests.

however, if i get some time, I'll see if I can torch most of our repo (sorry, it's not open-source, so I don't have the rights to just hand it over) and produce a minimal repo

[fluffynuts]

I'm not sure if you've had any luck with this, but I've created a minimal repo using our tooling scripts & environment, just want to get someone at work to double-check that I'm not leaking out any code that I shouldn't and perhaps I'll have a repro repo available (:

[ahnpnl]

still no luck, I just generated a Vue 2 project by using @vue/cli here https://github.com/ahnpnl/vue-ts-jest-example . I ran the example test provided by the CLI and the test passed.

[fluffynuts]

ok, well, my repro repo is in review; hopefully I can get you something useful soon. I have exactly one test in there, and an empty App.vue, so it's about as simple as I can get it (app-wise) though our build infra is a little less-ordinary (:

[fluffynuts]

@ahnpnl repro repo is at: https://github.com/codeo-za/ts-jest-2085-repro

hope this helps

[ahnpnl]

I got error with npm

with yarn also error

[fluffynuts]

ah yes, we use font-awesome pro version, which you won't need; let me clear it out of the package.json
