Installation
npm install betest --save-devFor beta see Github
npm install betest@beta --save-devUsage
Assuming that you have folder "tests" and file "index.js" inside.
node ./tests/index.jsor add this to your package.json
"scripts": {
"test": "node ./tests/index.js"
},Example
Create an instance of Betest:
import {Betest} from 'betest';
const betest = new Betest();You can choose how results will be look in console using parameters object:
betestParams = {
results: {
showAs: "Table" // or "Line"(Colorful PASS/FAIL)
}
}
const betest = new Betest(betestParams);Add your named group and functions using method "addGroup":
betest.addGroup(
{
name: "Example Group",
tests: [
{
expected: {
fisrstName: "First Name",
secondName: "Second Name"
},
test: function checkObject() {
return {
fisrstName: "First Name",
secondName: "Second Name"
}
}
},
{
expected: 7,
test: function findHypotenuse() {
return Math.round(Math.sqrt(5 ** 2 + 5 ** 2));
}
},
{
expected: [
[6, -8, 1],
[4, 1, 0],
[2, 3, 5]
],
test: function checkArrayEquality() {
return [
[6, -8, 1],
[4, 1, 0],
[2, 3, 5]
]
}
}
]
}
);You can run all tests in all groups, either one group or only one test in the group:
- Run all tests in all groups
betest.runAll();- Run only one group's tests
betest.runGroup("Example Group");- Run only one test in the group
betest.runTest("Example Group", "findHypotenuse");Or you can run test on the fly
betest.go(
[ // groups
{ // one group
tests: {
expected: 1,
test: function findSinus() {
return Math.sin(90 * 180 / Math.PI);
}
}
}
]
);And see results:
| (index) | (name) | Values |
|---|---|---|
| 0 | multiplication | true |
| 1 | sum | true |
Constructor Params
const betestParams = {
results: {
// 1. "Table" for table result.
// 2. "Line" for colorful PASS/FAIL message
showAs: string
}
}
