Description

提醒一下，这个项目是基于Glitch的以下入门项目构建的，或者是从GitHub克隆的。使用assert.isTrue（）或assert.isNotTrue（）来使测试通过。 .isTrue（true）和.isNotTrue（其他所有内容）都将通过。 .isFalse（）和.isNotFalse（）也存在。

tests:
  - text: 所有测试都应该通过
    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: 选择正确的断言 -  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); })'

    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); })'

    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); })'
