# --description--
|
|
|
|
As a reminder, this project is being built upon the following starter project on [Repl.it](https://repl.it/github/freeCodeCamp/boilerplate-mochachai), or cloned from [GitHub](https://github.com/freeCodeCamp/boilerplate-mochachai/).
|
|
|
|
`isString` or `isNotString` asserts that the actual value is a string.
|
|
|
|
# --instructions--
|
|
|
|
Within `tests/1_unit-tests.js` under the test labelled `#13` in the `Strings` suite, change each `assert` to either `assert.isString` or `assert.isNotString` 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=12').then(
|
|
(data) => {
|
|
assert.equal(data.state, 'passed');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should choose the correct method for the first assertion - `isString` vs. `isNotString`.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=12').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.assertions[0].method,
|
|
'isNotString',
|
|
'A float number is not a string'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should choose the correct method for the second assertion - `isString` vs. `isNotString`.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=12').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.assertions[1].method,
|
|
'isString',
|
|
'environment vars are strings (or undefined)'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should choose the correct method for the third assertion - `isString` vs. `isNotString`.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=12').then(
|
|
(data) => {
|
|
assert.equal(data.assertions[2].method, 'isString', 'A JSON is a string');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
