  - 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: 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: 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); })'
