請注意,本項目在這個 Replit 項目的基礎上進行開發。你也可以從 GitHub 上克隆。
--instructions--
在 tests/1_unit-tests.js
中,在標有 #8
的 Comparisons
套件裏,將每個 assert
改成 assert.isAbove
或 assert.isAtMost
方法,讓測試通過(結果應該返回 true
)。 不要改變傳入斷言的參數。
--hints--
不應有未通過的測試
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
(data) => {
assert.equal(data.state, 'passed');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
請爲第一個斷言選擇正確的方法 — isAbove
或 isAtMost
。
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
(data) => {
assert.equal(
data.assertions[0].method,
'isAtMost',
'5 is at most (<=) 5'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
請爲第二個斷言選擇正確的方法 — isAbove
或 isAtMost
。
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
(data) => {
assert.equal(data.assertions[1].method, 'isAbove', '1 is greater than 0');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
請爲第三個斷言選擇正確的方法 — isAbove
或 isAtMost
。
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
(data) => {
assert.equal(
data.assertions[2].method,
'isAbove',
'Math.PI = 3.14159265 is greater than 3'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
請爲第四個斷言選擇正確的方法 — isAbove
或 isAtMost
。
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
(data) => {
assert.equal(
data.assertions[3].method,
'isAtMost',
'1 - Math.random() is > 0 and <= 1. It is atMost 1 !'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
