how to mock two tables?

hi! i currently have the following snippet 
it("createUserProfile should  create a person", async () => {
  const ctx = {
    db: {
      insert: vi.fn(),
      query: vi.fn().mockReturnValue({
        withIndex: vi.fn().mockReturnValue({
          unique: vi.fn().mockReturnValue(null),
        }),
      }),
    },
    auth: {
      getUserIdentity: vi.fn().mockReturnValue(
        Promise.resolve({
          tokenIdentifier: "user id",
        })
      ),
    },
  }

  // @ts-ignore
  await createUserProfile(ctx, { clerkOrgId: "fake org id" })
  expect(ctx.db.insert.mock.calls.length === 1)
  expect(ctx.db.insert.mock.calls[0]).toEqual([
    "user",
    {
      clerkOrgId: "fake org id",
      clerkUserId: "user id",
    },
  ])
})
it("createUserProfile should  create a person", async () => {
  const ctx = {
    db: {
      insert: vi.fn(),
      query: vi.fn().mockReturnValue({
        withIndex: vi.fn().mockReturnValue({
          unique: vi.fn().mockReturnValue(null),
        }),
      }),
    },
    auth: {
      getUserIdentity: vi.fn().mockReturnValue(
        Promise.resolve({
          tokenIdentifier: "user id",
        })
      ),
    },
  }

  // @ts-ignore
  await createUserProfile(ctx, { clerkOrgId: "fake org id" })
  expect(ctx.db.insert.mock.calls.length === 1)
  expect(ctx.db.insert.mock.calls[0]).toEqual([
    "user",
    {
      clerkOrgId: "fake org id",
      clerkUserId: "user id",
    },
  ])
})
what happens if createUserProfile so happen to call 2 DBs? can i do something like 
const ctx = {
    db: 
       db1: {},
       db2: {},
...
const ctx = {
    db: 
       db1: {},
       db2: {},
...
getting an error when i try it 😅

sorry, lemme try again. is it possible to mock two different docs / dbs? im trying to do 
 const ctx = {
    db: {
      insert: vi.fn(),
      query: vi.fn().mockReturnValue({
        db1: {
          filter: vi.fn().mockReturnValue({}),
        },
        db2: vi.fn().mockReturnValue({}),
      }),
    },

const ctx = {
  db: {
     db1: {
       insert: vi.fn(),
       query: vi.fn().mockReturnValue({}),
     },
     db2: {
       insert: vi.fn(),
       query: vi.fn().mockReturnValue({}),
     },
 const ctx = {
    db: {
      insert: vi.fn(),
      query: vi.fn().mockReturnValue({
        db1: {
          filter: vi.fn().mockReturnValue({}),
        },
        db2: vi.fn().mockReturnValue({}),
      }),
    },

const ctx = {
  db: {
     db1: {
       insert: vi.fn(),
       query: vi.fn().mockReturnValue({}),
     },
     db2: {
       insert: vi.fn(),
       query: vi.fn().mockReturnValue({}),
     },
but i didnt seem to quite get them correct. my function that im trying to test looks like this 
const currentUser = await ctx.db
  .query('db1')
  .filter((q) => q.and(q.eq(q.field("email"), email)))
  .unique()

const userAgain = await ctx.db
  .query("db2")
  .filter((q) => q.eq(q.field("userId"), currentUser._id))
  .unique()  
const currentUser = await ctx.db
  .query('db1')
  .filter((q) => q.and(q.eq(q.field("email"), email)))
  .unique()

const userAgain = await ctx.db
  .query("db2")
  .filter((q) => q.eq(q.field("userId"), currentUser._id))
  .unique()
im not sure which part of the mocking i've messed up 😦 can u pls help me out? oh looks like i fixed it by doing 
const ctx = {
  db: {
    insert: vi.fn(),
    query: vi.fn().mockImplementation((dbName) => {
      if (dbName === "db1") {
        return {
          filter: vi.fn().mockReturnValue({}),
        }
      } else if (dbName === "db2") {
        return vi.fn().mockReturnValue({})
      }
    }),
  },
const ctx = {
  db: {
    insert: vi.fn(),
    query: vi.fn().mockImplementation((dbName) => {
      if (dbName === "db1") {
        return {
          filter: vi.fn().mockReturnValue({}),
        }
      } else if (dbName === "db2") {
        return vi.fn().mockReturnValue({})
      }
    }),
  },

Btw we call db1 and db2 "tables" in the Convex lingo.
