jest: toBeGreaterThan message correction for failing case

Improvement

This bug was While a case fails for the condition where user expect the result to be greater than certain value , jest reply with the message of expecting a value same as the argument that is passed to function toBeGreaterThan() . It should show something more detailed like >0 or min 1 In case of argument value as 0.

To Reproduce

Steps to reproduce the behavior: 1 Write the function registerUsername as mentioned:-

function registerUsername(username) {
   if (!username) throw new Error('Username is required.');
   return { id: 0, username: username }
}

2 Write a testcase as mentioned:-

describe('registerUser', () => {
    it('should return a user object if valid username is passed', () => {
        const result = lib.registerUser('Abhi')
        expect(result).toMatchObject({ username: 'Abhi'})
        expect(result.id).toBeGreaterThan(0)
    })
})

3 Now run the test.

Expected behavior

● registerUser › should return a user object if valid username is passed

expect(received).toBeGreaterThan(expected)

Expected value to be greater than: 0
