Asserts that all items of an array (or array-like object) satisfy a given assertion or function.
Alias: to be an array whose items satisfy
.
Notice this assertion fails when given an empty array.
expect([0, 1, 2, 3, 4], 'to have items satisfying', function (item, index) {
expect(item, 'to be a number');
});
expect([0, 1, 2, 3, 4], 'to have items satisfying', 'to be a number');
expect([[1], [2]], 'to have items satisfying',
'to have items satisfying', 'to be a number');
expect([1, 2, 3, 4], 'to have items satisfying',
expect.it('to be a number').and('to be positive'));
In case of a failing expectation you get the following output:
expect([ [0, 1, 2], [4, '5', '6'], [7, '8', 9] ],
'to have items satisfying',
'to have items satisfying',
'to be a number');
expected [ [ 0, 1, 2 ], [ 4, '5', '6' ], [ 7, '8', 9 ] ]
to have values satisfying 'to have items satisfying', 'to be a number'

Here a another example:
expect([0, 1, 2, 3, 4], 'to have items satisfying',
expect.it('to be a number').and('to be positive'));
expected [ 0, 1, 2, 3, 4 ] to have values satisfying
expect.it('to be a number')
.and('to be positive')
