As a reminder, this project is being built upon the following starter project cloned from <a href="https://github.com/freeCodeCamp/boilerplate-mochachai/" target="_blank" rel="noopener noreferrer nofollow">GitHub</a>.
Within tests/1_unit-tests.js under the test labeled #2 in the Basic Assertions suite, change each assert to either assert.isDefined() or assert.isUndefined() to make the test pass (should evaluate to true). Do not alter the arguments passed to the asserts.
All tests should pass.
const response = await fetch(code + '/_api/get-tests?type=unit&n=1');
if (!response.ok) {
throw new Error(await response.text());
}
const data = await response.json();
assert.equal(data.state, 'passed');
You should choose the correct method for the first assertion - isDefined vs. isUndefined.
const response = await fetch(code + '/_api/get-tests?type=unit&n=1');
if (!response.ok) {
throw new Error(await response.text());
}
const data = await response.json();
assert.equal(
data.assertions[0].method,
'isDefined',
'Null is not undefined'
);
