I have this unit test :

import { describe, expect, it } from "@jest/globals"

import { format2APIDate } from "../helpers"

describe("format2APIDate()", () => {
  it("should return a date with the format: YYYY/MM/DD for date with this format YYYY-MM-DD", () => {
    const date = new Date("2024-02-12")

    const formattedDate = format2APIDate(date)

    expect(formattedDate).toBe("2024/02/12")
  })

  it("should return a date with the format: YYYY/MM/DD when a date has this format", () => {
    const date = new Date("Mon Feb 12 2024 00:00:00 GMT+0100 (Central European Standard Time)")

    const formattedDate = format2APIDate(date)

    expect(formattedDate).toBe("2024/02/12")
  })
})

When I run the tests locally:

npm run test.

They are passed.

However, when I merge the changes, the last test fails:
