587d824a367417b2b2512c46 | Learn How JavaScript Assertions Work | 2 | 301589 | learn-how-javascript-assertions-work |
--description--
As a reminder, this project is being built upon the following starter project on Repl.it, or cloned from GitHub.
--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);
}
