587d824a367417b2b2512c46 | Learn How JavaScript Assertions Work | 2 | 301589 | learn-how-javascript-assertions-work |
--description--
Working on these challenges will involve you writing your code using one of the following methods:
- Clone this GitHub repo and complete these challenges locally.
- Use our Repl.it starter project to complete these challenges.
- Use a site builder of your choice to complete the project. Be sure to incorporate all the files from our GitHub repo.
When you are done, make sure a working demo of your project is hosted somewhere public. Then submit the URL to it in the Solution Link
field.
--instructions--
Within tests/1_unit-tests.js
under the test labelled #1
in the Basic Assertions
suite, change each assert
to either assert.isNull
or assert.isNotNull
to make the test pass (should evaluate to true
). Do not alter the arguments passed to the asserts.
--hints--
All tests should pass.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=0').then(
(data) => {
assert.equal(data.state, 'passed');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the first assertion - isNull
vs. isNotNull
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=0').then(
(data) => {
assert.equal(data.assertions[0].method, 'isNull', 'Null is null');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);

},
(xhr) => {
throw new Error(xhr.responseText);

Backend challenges don't need solutions,
because they would need to be tested against a full working project.
