使用 assert.equal() 或 assert.notEqual() 让所有测试通过。

Tests

tests:
  - text: 不应有未通过的测试
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—equal 或 notEqual
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(data => {  assert.equal(data.assertions[0].method, 'equal', 'Numbers are coerced into strings with == '); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—equal 或 notEqual
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(data => {  assert.equal(data.assertions[1].method, 'notEqual', ' == compares object references'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—equal 或 notEqual
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(data => {  assert.equal(data.assertions[2].method, 'equal', '6 * \'2\' is 12 ! It should be equal to \'12\''); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—equal 或 notEqual
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(data => {  assert.equal(data.assertions[3].method, 'notEqual', '6 + \'2\' is \'62\'...'); }, xhr => { throw new Error(xhr.responseText); })
