YeetCode

Promise Based Unit Testing

Git repo

https://github.com/alanngo/yeetcode.git

NPM package

https://www.npmjs.com/package/yeetcode

Install

$ npm install yeetcode

Create a simple test case

import test from 'yeetcode'

const foo = (a,b) => a + b
test("TestDescription").then(ut =>
{
    ut.assertEq(5, foo(3, 2))
})

Run multiple tests

import test from 'yeetcode'


test("Test Suite 0").then(ut =>
{
    // test cases here
    ...
}).then(() =>
{
    test("Test Suite 1").then(ut =>
    {
        // more test cases
        ...
    })
}).then(() =>
{
    test("Test Suite 2").then(ut =>
    {
        // more test cases
        ...
    })
})
...

Options

Default configuration

{
    haltOnFailure: true, // stop or continue tests after failure
    writeToFile: false // output test results to 'results.log'
}

Creating Test w/ Options

const options = {haltOnFailure: false} // all tests will run regardless of failure
import test from 'yeetcode'

const foo = (a,b) => a + b
test("TestDescription", options).then(ut =>
{
    ut.assertEq(5, foo(3, 2))
})
