27.3.1
Steps to reproduce
Clone MatrixAI/TypeScript-Demo-Lib#38. Run nix-shell to enter into the development environment.
Go to src/native/index.cpp.
NAPI_METHOD(createArr) {
// Create arr with length of 1
napi_value arr;
NAPI_STATUS_THROWS(napi_create_array_with_length(env, 1, &arr))
// Set the value on the arr
napi_value value;
NAPI_STATUS_THROWS(napi_create_double(env, 0.5, &value));
NAPI_STATUS_THROWS(napi_set_element(env, arr, 0, value))
return arr;
}This native function just creates an JS array, and sets 5 to it. Basically [5].
Now in jest, go to tests/native.test.ts.
Test this:
expect(native.createArr()).toEqual([0.5]);
Expected behavior
I would expect [0.5] to be [0.5].
Actual behavior
It says: Received: serializes to the same string.
In fact, you can test it like:
const arr = native.createArr();
expect(arr[0]).toStrictEqual(0.5);And this does work.
