challengeType: 2
---
## Description
As a reminder, this project is being built upon the following starter project on Glitch, or cloned from GitHub.
## Instructions
Use assert.isTrue()
or assert.isNotTrue()
to make the tests pass.
.isTrue(true)
and .isNotTrue(everything else)
will pass.
.isFalse()
and .isNotFalse()
also exist.
## Tests
```yml
tests:
- text: All tests should pass
testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
- text: Choose the right assertion - isTrue vs. isNotTrue
testString: 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); })
- text: Choose the right assertion - isTrue vs. isNotTrue
testString: 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); })
- text: Choose the right assertion - isTrue vs. isNotTrue
testString: 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); })
