--description--
As a reminder, this project is being built upon the following starter project on Repl.it, or cloned from GitHub.
strictEqual()
compares objects using ===
.
--instructions--
Within tests/1_unit-tests.js
under the test labelled #6
in the Equality
suite, change each assert
to either assert.strictEqual
or assert.notStrictEqual
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=5').then(
(data) => {
assert.equal(data.state, 'passed');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the first assertion - strictEqual
vs. notStrictEqual
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
(data) => {
assert.equal(
data.assertions[0].method,
'notStrictEqual',
'with strictEqual the type must match'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the second assertion - strictEqual
vs. notStrictEqual
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
(data) => {
assert.equal(data.assertions[1].method, 'strictEqual', '3*2 = 6...');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the third assertion - strictEqual
vs. notStrictEqual
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
(data) => {
assert.equal(
data.assertions[2].method,
'strictEqual',
"6 * '2' is 12. Types match !"
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the fourth assertion - strictEqual
vs. notStrictEqual
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
(data) => {
assert.equal(
data.assertions[3].method,
'notStrictEqual',
'Even if they have the same elements, the Arrays are notStrictEqual'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
