587d824b367417b2b2512c49 | Test for Truthiness | 2 | 301596 |
Description
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 similary to their true counterparts except they look for the boolean value of false.
Instructions
assert.isTrue()
or assert.isNotTrue()
to make the tests pass.
Tests
tests:
- text: All tests should pass
testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=3').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
- text: Choose the right assertion - isTrue vs. isNotTrue
testString: 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); })
- text: Choose the right assertion - isTrue vs. isNotTrue
testString: 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); })
- text: Choose the right assertion - isTrue vs. isNotTrue
testString: 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); })
