--description--

As a reminder, this project is being built upon the following starter project on Gitpod, or cloned from GitHub.

isTrue() will test for the boolean value true and isNotTrue() will pass when given anything but the boolean value of true.

assert.isTrue(true, 'This will pass with the boolean value true');
assert.isTrue('true', 'This will NOT pass with the string value "true"');
assert.isTrue(1, 'This will NOT pass with the number value 1');

isFalse() and isNotFalse() also exist, and behave similarly to their true counterparts except they look for the boolean value of false.

--instructions--

Within tests/1_unit-tests.js under the test labeled #4 in the Basic Assertions suite, change each assert to either assert.isTrue or assert.isNotTrue 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=3').then(
(data) => {
assert.equal(data.state, 'passed');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);

You should choose the correct method for the first assertion - isTrue vs. isNotTrue.

(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(
(data) => {
assert.equal(data.assertions[0].method, 'isTrue', 'True is true');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);

You should choose the correct method for the second assertion - isTrue vs. isNotTrue.

(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(
(data) => {
assert.equal(
data.assertions[1].method,
'isTrue',
'Double negation of a truthy value is true'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);

You should choose the correct method for the third assertion - isTrue vs. isNotTrue.

(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(
(data) => {
assert.equal(
data.assertions[2].method,
'isNotTrue',
'A truthy object is not true - neither is a false one'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
