--description--
As a reminder, this project is being built upon the following starter project on Repl.it, or cloned from GitHub.
equal()
compares objects using ==
.
--instructions--
Within tests/1_unit-tests.js
under the test labelled #5
in the Equality
suite, change each assert
to either assert.equal
or assert.notEqual
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=4').then(
(data) => {
assert.equal(data.state, 'passed');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the first assertion - equal
vs. notEqual
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
(data) => {
assert.equal(
data.assertions[0].method,
'equal',
'Numbers are coerced into strings with == '
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the second assertion - equal
vs. notEqual
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
(data) => {
assert.equal(
data.assertions[1].method,
'notEqual',
' == compares object references'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the third assertion - equal
vs. notEqual
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
(data) => {
assert.equal(
data.assertions[2].method,
'equal',
"6 * '2' is 12 ! It should be equal to '12'"
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
You should choose the correct method for the fourth assertion - equal
vs. notEqual
.
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
(data) => {
assert.equal(data.assertions[3].method, 'notEqual', "6 + '2' is '62'...");
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
