`convex-test` could not find the "_generated" directory

Just installed convex-test and wrote a very simple test at the root of my /convex folder. Running it produces an error:

Error: Could not find the "_generated" directory, make sure to run `npx convex dev` or `npx convex codegen`. If your Convex functions aren't defined in a directory called "convex" sibling to your node_modules, provide the second argument to `convexTest`

Error: Could not find the "_generated" directory, make sure to run `npx convex dev` or `npx convex codegen`. If your Convex functions aren't defined in a directory called "convex" sibling to your node_modules, provide the second argument to `convexTest`

My _generated directory is present and my convex functions are all in /convex at the root of my project. Not sure what might be the issue.

@Eva facing the same issue...how did you fix it?

morvud•4mo ago

I had the same issue and fixed it with this

const t = convexTest(schema, import.meta.glob("./**/*.*s"));

const t = convexTest(schema, import.meta.glob("./**/*.*s"));

Satchamo•4mo ago

In nextjs i get this error: js Property 'glob' does not exist on type 'ImportMeta'.ts(2339)

morvud•4mo ago

nextjs shouldn't even be loading the test file, are you exporting anything from the test file that might be used in your nextjs code?

Satchamo•4mo ago

No I'm only doing imports in my test files

re: Could not find the "_generated" directory -- I think something about pnpm sometimes does not play nicely with convexTest automatically finding your convex functions. The workaround is what morvud described of passing in a import.meta.glob (and I'll update the docs + error message to recommend this for pnpm). To get import.meta.glob to typecheck, I believe you want to add /// <reference types="vite/client" /> to the top of whatever file you're defining your glob in as shown in https://docs.convex.dev/testing/convex-test#custom-convex-folder-name-or-location (or in a pinch, add a // @ts-expect-error comment above the line TypeScript is unhappy about)

convex-test | Convex Developer Hub

The convex-test library provides a mock implementation of the Convex backend

EvaOP•4mo ago

That's correct, the advice in the docs now is what I did. Defining test.setup.ts:

/// <reference types="vite/client" />
export const modules = import.meta.glob("./**/!(*.*.*)*.*s");

/// <reference types="vite/client" />
export const modules = import.meta.glob("./**/!(*.*.*)*.*s");

And then importing modules to use within the arguments of convexTest():

import { convexTest } from "convex-test";
import { expect, test } from "vitest";
import schema from "./schema";
import { modules } from "./test.setup";

test("my test", async () => {
  const t = convexTest(schema, modules);
  // ... test
});

import { convexTest } from "convex-test";
import { expect, test } from "vitest";
import schema from "./schema";
import { modules } from "./test.setup";

test("my test", async () => {
  const t = convexTest(schema, modules);
  // ... test
});

Would love if the library could be updated to avoid this for pnpm, definitely feels like extra boilerplate!
