Testr
gitr done, testr first
Testr is a flexible, lightweight and based testing library for JS. It's designed to work seamlessly in both browser and Node.js environments. It supports a variety of features such as nesting, asynchronous execution, and exclusion/inclusion of test cases to streamline your testing workflow.
Installation
To install Testr, use npm:
npm i -D @basd/testr
Usage
Basic Usage
Here is a simple example of using Testr:
const Testr = require('@basd/testr')
const testr = new Testr()
testr.describe('A test suite', () => {
testr.it('A test case', () => {
if (1 + 1 !== 2) {
throw new Error('Math is broken!')
}
expect(2 + 2).to.equal(4)
})
})
testr.run()
Or you can instantiate and destructure the functions you need:
const { describe, it, before, after, expect, assert, run, testr } = new Testr()
// or as a function
const { describe, it, before, after, expect, assert, run, testr } = Testr()
// which means you can do this:
const { describe, it, before, after, expect, assert, run, testr } = require('@basd/testr')()
In this example, we create a test suite with describe()
, add a test case with it()
, and run our tests with run()
.
Skipping and Only Running Certain Tests
You can also mark test cases or suites to be skipped with describe.omit()
and it.omit()
, or to be the only ones run with describe.only()
and it.only()
.
describe.omit('A skipped test suite', () => {
it('A skipped test case', () => {})
})
describe.only('A test suite to run alone', () => {
it.only('A test case to run alone', () => {})
})
Before and After Hooks
You can use before.each()
, after.each()
, before.all()
, and after.all()
to set up and tear down for tests:
describe('A test suite', () => {
let counter = 0
before.each(() => {
counter = 1
})
it('A test case', () => {
if (counter !== 1) {
throw new Error('Counter not initialized!')
}
})
after.each(() => {
counter = 0
})
})
Node.js Environment
For Node.js environments, TestrNode
provides additional functionality:
const TestrNode = require('@basd/testr')
TestrNode.explode('path/to/tests', ['path/to/tests/to/ignore'])
In this example, TestrNode
will automatically find and require test files in the specified directory that end with .test.js
, and ignore the ones in the directories to ignore.
CLI Usage
If you have installed Testr globally or in your project, you can use the testr
command to run your tests from the command line:
# Run all test files in a directory
testr path/to/tests
# Run all test files, except those in certain directories (coming soon..)
testr path/to/tests --ignore path/to/tests/to/ignore
This will automatically find and run any files ending with .test.js
.
