Helpful for assertion libraries that do not throw when they reach the first failed assertion, but try every assertion possible (like tap and ava).
assert._reset(); //clear log of assertions
assert.ok(two + two === 4);
assert.ok(three + two === 5);
assert.ok(four + two === 6);
assert._callStack();
// => [
// {content: 'assert.ok(two + two === 4);', args:[...]},
// {content: 'assert.ok(three + two === 5);', args:[...]},
// {content: 'assert.ok(four + two === 6);', args:[...]}
// ]
