# --description--
|
|
|
|
As a reminder, this project is being built upon the following starter project on [Replit](https://replit.com/github/freeCodeCamp/boilerplate-mochachai), or cloned from [GitHub](https://github.com/freeCodeCamp/boilerplate-mochachai/).
|
|
|
|
`isTrue()` will test for the boolean value `true` and `isNotTrue()` will pass when given anything but the boolean value of `true`.
|
|
|
|
```js
|
|
assert.isTrue(true, 'This will pass with the boolean value true');
|
|
assert.isTrue('true', 'This will NOT pass with the string value "true"');
|
|
assert.isTrue(1, 'This will NOT pass with the number value 1');
|
|
```
|
|
|
|
`isFalse()` and `isNotFalse()` also exist, and behave similarly to their true counterparts except they look for the boolean value of `false`.
|
|
|
|
# --instructions--
|
|
|
|
Within `tests/1_unit-tests.js` under the test labelled `#4` in the `Basic Assertions` suite, change each `assert` to either `assert.isTrue` or `assert.isNotTrue` to make the test pass (should evaluate to `true`). Do not alter the arguments passed to the asserts.
|
|
|
|
# --hints--
|
|
|
|
All tests should pass.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(
|
|
(data) => {
|
|
assert.equal(data.state, 'passed');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should choose the correct method for the first assertion - `isTrue` vs. `isNotTrue`.
|
|
|
|
```js
|
|
(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);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should choose the correct method for the second assertion - `isTrue` vs. `isNotTrue`.
|
|
|
|
```js
|
|
(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);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should choose the correct method for the third assertion - `isTrue` vs. `isNotTrue`.
|
|
|
|
```js
|
|
(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);
|
|
}
|
|
);
|
|
```
