Testing is something that every good project needs - but sometimes we don't need all the features of larger testing frameworks in smaller applications.
Enter in Test24 - an ultra-lightweight testing solution, designed as a way to make testing more accessible for those small projects.
Clone this repo and copy the tests.js file, or just copy the code from tests.js directly into your project.
Usage is very straightforward, please see the following example code:
function myFunc(num) { if (typeof num !== 'number') { return null } if (num === -0) { num = Math.abs(num) } return num * 2; } test({ "Should handle zeros correctly": () => assert(myFunc(0) === 0), "Should handle negative zeros correctly": () => assert(myFunc(-0) === 0), "Should handle positive numbers": () => assert(myFunc(2) === 4), "Should handle negative numbers": () => assert(myFunc(-2) === -4), "Should handle non-numbers": () => assert(myFunc() === null), "Should fail this": () => assert(myFunc(1) === 1), "Should pass this": () => assert(myFunc(1) === 2) })
Which outputs the following results:
