javascript-quiz-project's Issues

Tests for shuffleChoices() and shuffleQuestions() have relatively high chances of false positives

Current Behavior

The way tests are currently implemented, there's some chances of students getting a positive (ie. a student has implemented the logic correctly but the test fails).

  • shuffleChoices(): test is implemented with an array of 5 elements (0.83% chances of a false positive)
  • shuffleQuestions(): test is implemented with an array of 3 elements (16.67% chances of a false positive)

This seemed to create some frustration and uncertainty in students ("it keeps saying that I've done something wrong and it's not working when in reality is the test that isn't functioning").

Suggested Solution

We can keep the tests implemented as they are (code is easy to understand for any student that wants to read the tests) but use a bigger array.

For example, using an array of 7 elements, chances of a false positive become 0.02%.
