is there a test implementation of `GenericMutationCtx`?

hi team! i wonder if it's possible to get a test version of GenericMutationCtx that i can override in the test files? i've been doing @ts-ignore for the ctx in myFunc and it's been tripping me all over 😂

Sooner than later we will provide a way to test queries and mutations. Stay tuned!

thanks michal. in the meantime, do u know how can i make my test more robust? i want to do a match on the arg im passing in

it("validateUserNotFound should throw if user exists", async () => {
  const ctx = {
    db: {
      query: vi.fn().mockImplementation((db) => {
        if (db === "user") {
          return {
            filter: vi.fn().mockReturnValue({
              unique: vi.fn().mockReturnValue({
                _id: "user id",
              }),
            }),
          }
        }
      }),
    },
    auth: mockAuth(),
  }

  await expect(
    validateUserNotFound(ctx, { email: "hello@world.com" })
  ).rejects.toThrow("User already exists")
})

// my actual function
const user = await ctx.db
      .query(USER_DB)
      .filter((q) => q.eq(q.field("email"), args.email))
      .unique()
if (user) {
  throw new Error("User already exists")
}

it("validateUserNotFound should throw if user exists", async () => {
  const ctx = {
    db: {
      query: vi.fn().mockImplementation((db) => {
        if (db === "user") {
          return {
            filter: vi.fn().mockReturnValue({
              unique: vi.fn().mockReturnValue({
                _id: "user id",
              }),
            }),
          }
        }
      }),
    },
    auth: mockAuth(),
  }

  await expect(
    validateUserNotFound(ctx, { email: "hello@world.com" })
  ).rejects.toThrow("User already exists")
})

// my actual function
const user = await ctx.db
      .query(USER_DB)
      .filter((q) => q.eq(q.field("email"), args.email))
      .unique()
if (user) {
  throw new Error("User already exists")
}

is it possible to do some sort of filter: vi.fn().IF_EMAIL_MATCHES_hello@world.com.mockReturnValue()?

You can do mockImplementation instead of mockReturnValue

thanks. ok i think im close,

filter: vi.fn().mockImplementation((func) => {
  if (func({ _id: "user id" })) {
    return {
      q: vi.fn().mockImplementation(() => ({
        field: vi.fn().mockImplementation(() => ({
                    unique: vi.fn().mockReturnValue({
                      _id: "user id",
                    }),
                  })),
              })),
            }
          } else {
        })),
      })),
    }

filter: vi.fn().mockImplementation((func) => {
  if (func({ _id: "user id" })) {
    return {
      q: vi.fn().mockImplementation(() => ({
        field: vi.fn().mockImplementation(() => ({
                    unique: vi.fn().mockReturnValue({
                      _id: "user id",
                    }),
                  })),
              })),
            }
          } else {
        })),
      })),
    }

but still getting TypeError: q.field is not a function im not sure if im doing the lambda func wrongly...? do u have any idea?

I think this is super cumbersome. Could you pull out the whole DB read into a function and mock that instead?

is there a test implementation of `GenericMutationCtx`?
