Description

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

Instructions

Use assert.isNull() or assert.isNotNull() to make the tests pass.

Tests

tests:
  - text: All tests should pass.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=0').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: You should choose the right assertion - isNull vs. isNotNull.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=0').then(data => {  assert.equal(data.assertions[0].method, 'isNull', 'Null is null'); }, xhr => { throw new Error(xhr.responseText); })
  - text: You should choose the right assertion - isNull vs. isNotNull.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=0').then(data => {  assert.equal(data.assertions[1].method, 'isNotNull', '1 is not null'); }, xhr => { throw new Error(xhr.responseText); })

Solution

/**
  Backend challenges don't need solutions, 
  because they would need to be tested against a full working project.
