.toHaveBeenLastCalledWith()

This assertion checks that the last time a mock was called it was with certain arguments.

const mock = jest.fn();

mock('foo', 'foo');

mock('foo', 'baz');

jestUnexpected(mock).toHaveBeenLastCalledWith('foo', 'bar');

expected

function mockConstructor() {

return fn.apply(this, arguments);

}

to have been last called with CalledWithSpec({ spec: [ 'foo', 'bar' ], value: 2, nested: false })

[

'foo',

'baz'

should equal

'bar'

baz

bar

]
