// Set up Unexpected plugins (on the actual unexpected instance, so they show up when it is imported by other modules).
expect.installPlugin(unexpectedSinon);
// Automatically restore Sinon stubs after tests end.
var oldWrap = sinon.wrapMethod;
var wrappeds = [];
var afterSetup = false;
sinon.wrapMethod = function (...args) {
var out = oldWrap.apply(sinon, args);
wrappeds.push(out);
if (!afterSetup) {
// Delay setting up afterEach since it is not yet defined when this module is run.
afterEach(() => {
wrappeds.forEach(wrapped => {
wrapped.restore();
});
wrappeds = [];
});
