--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 #11
in the Arrays
suite, change each assert
to either assert.isArray
or assert.isNotArray
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=10').then(
(data) => {
assert.equal(data.state, 'passed');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the first assertion - isArray
vs. isNotArray
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=10').then(
(data) => {
assert.equal(
data.assertions[0].method,
'isArray',
'String.prototype.split() returns an Array'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
