The .every(...).toBe(true) pattern gives very poor failure messages — when a value fails the predicate, Jest just says expected false to be true with no indication of which value failed or what it was.

Prefer individual assertions per entry using forEach, or at minimum use toStrictEqual on a mapped result:

Suggested change
entryValues.length
)
expect(stringEntries.length).toBeGreaterThan(0)
expect(arrayEntries.length).toBeGreaterThan(0)
expect(stringEntries.every((entryValue) => entryValue.length > 0)).toBe(
true
)
expect(flattenedArrayEntries.length).toBeGreaterThan(0)
expect(
flattenedArrayEntries.every(
(entryValue) => typeof entryValue === "string"
)
).toBe(true)
})
expect(stringEntries.length + arrayEntries.length).toBe(
entryValues.length
)
expect(stringEntries.length).toBeGreaterThan(0)
expect(arrayEntries.length).toBeGreaterThan(0)
stringEntries.forEach((entryValue) =>
expect(typeof entryValue).toBe("string")
)
expect(flattenedArrayEntries.length).toBeGreaterThan(0)
flattenedArrayEntries.forEach((entryValue) =>
expect(typeof entryValue).toBe("string")
)

This way, a failure names the offending value directly.
