Asserts that all values of an object satisfy a given assertion or function.
Notice this assertion fails when given an empty object.
Aliases: `to be a map whose values satisfy`,
`to be an object whose values satisfy`, `to be a hash whose values satisfy`.
```javascript
expect({ foo: 0, bar: 1, baz: 2, qux: 3 },
'to have values satisfying', function (value, index) {
expect(value, 'to be a number');
});
expect({ foo: 0, bar: 1, baz: 2, qux: 3 },
'to have values satisfying',
'to be a number');
```
In case of a failing expectation you get the following output:
```javascript
expect({ foo: [0, 1, 2], bar: [4, 5, 6], baz: [7, 8, 9] },
'to have values satisfying',
'to have items satisfying',
expect.it('to be a number').and('to be below', 8));
```
```output
expected { foo: [ 0, 1, 2 ], bar: [ 4, 5, 6 ], baz: [ 7, 8, 9 ] } to have values satisfying
'to have items satisfying', expect.it('to be a number')
.and('to be below', 8)
{
foo: [...],
bar: [...],
baz: [
7,
8, // ✓ expected 8 to be a number and
// ⨯ expected 8 to be below 8
9 // ✓ expected 9 to be a number and
// ⨯ expected 9 to be below 8
]
}
```
