```yml
tests:
  - text: All tests should pass
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: Choose the right assertion - isTrue vs. isNotTrue
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(data => {  assert.equal(data.assertions[0].method, 'isTrue', 'True is true'); }, xhr => { throw new Error(xhr.responseText); })
  - text: Choose the right assertion - isTrue vs. isNotTrue
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(data => {  assert.equal(data.assertions[1].method, 'isTrue', 'Double negation of a truthy value is true'); }, xhr => { throw new Error(xhr.responseText); })
  - text: Choose the right assertion - isTrue vs. isNotTrue
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(data => {  assert.equal(data.assertions[2].method, 'isNotTrue', 'A truthy object is not true - neither is a false one'); }, xhr => { throw new Error(xhr.responseText); })
