Description

As a reminder, this project is being built upon the following starter project on Glitch, or cloned from GitHub.

.approximately(actual, expected, delta, [message]) Asserts that the actual is equal expected, to within a +/- delta range.

Instructions

Use assert.approximately() to make the tests pass. Choose the minimum range (3rd parameter) to make the test always pass. It should be less than 1.

Tests

tests:
  - text: All tests should pass
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=9').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: Use approximately(actual, expected, range) - Chose the correct range
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=9').then(data => {  assert.equal(data.assertions[0].method, 'approximately');  assert.equal(data.assertions[0].args[2], 0.5, 'weirdNumbers(0.5) is in the range (0.5, 1.5]. It\'s within 1 +/- 0.5'); }, xhr => { throw new Error(xhr.responseText); })
  - text: Use approximately(actual, expected, range) - Chose the correct range
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=9').then(data => {  assert.equal(data.assertions[1].method, 'approximately');  assert.equal(data.assertions[1].args[2], 0.8, 'weirdNumbers(0.2) is in the range (0.2, 1.2]. It\'s within 1 +/- 0.8'); }, xhr => { throw new Error(xhr.responseText); })
