# --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/).
|
||
|
|
|
||
|
|
`isOk()` will test for a truthy value, and `isNotOk()` will test for a falsy value.
|
||
|
|
|
||
|
|
To learn more about truthy and falsy values, try our [Falsy Bouncer](https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/basic-algorithm-scripting/falsy-bouncer) challenge.

# --instructions--
|
||
|
|
|
||
|
|
Within `tests/1_unit-tests.js` under the test labelled `#3` in the `Basic Assertions` suite, change each `assert` to either `assert.isOk()` or `assert.isNotOk()` 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=2').then(
|
||
|
|
(data) => {
|
||
|
|
assert.equal(data.state, 'passed');
|
||
|
|
},
|
||
|
|
(xhr) => {
|
||
|
|
throw new Error(xhr.responseText);
|
||
|
|
}
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
You should choose the correct method for the first assertion - `isOk` vs. `isNotOk`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
(getUserInput) =>
|
||
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=2').then(
|
||
|
|
(data) => {
|
||
|
|
assert.equal(data.assertions[0].method, 'isNotOk', 'Null is falsy');
|
||
|
|
},
|
||
|
|
(xhr) => {
|
||
|
|
throw new Error(xhr.responseText);
|
||
|
|
}
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
You should choose the correct method for the second assertion - `isOk` vs. `isNotOk`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
(getUserInput) =>
|
||
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=2').then(
|
||
|
|
(data) => {
|
||
|
|
assert.equal(data.assertions[1].method, 'isOk', 'A string is truthy');
|
||
|
|
},
|
||
|
|
(xhr) => {
|
||
|
|
throw new Error(xhr.responseText);
|
||
|
|
}
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
You should choose the correct method for the third assertion - `isOk` vs. `isNotOk`.

```js
|

|
|
(getUserInput) =>

||
|
|
(data) => {

|
|
assert.equal(data.assertions[2].method, 'isOk', 'true is truthy');
