test('compare float in object properties', () => {
expect({
title: '0.1 + 0.2',
sum: 0.1 + 0.2,
}).toEqual({
title: '0.1 + 0.2',
sum: expect.closeTo(0.3, 5),
});
});
Property 'closeTo' does not exist on type 'Expect'.
Why am I getting this error ?
First, I'd ensure @types/jest has the same version as jest package does.
As a last resort, you can extend type definition as we do for custom matchers:
interface CustomMatchers<R = unknown> {
closeTo(delta: number, value: number): R;
}
declare global {
namespace jest {
interface Expect extends CustomMatchers {}
}
}
