-# node-casette
+# casette
-No-dependancy test framework for node
+Casette is a no-nonsense, no dependancy small test framework created to use in node 13 with ECM.
+
+# Installation
+
+Install with npm globally:
+
+```bash
+$ npm install --global casette
+```
+
+or as a development dependency for your project:
+
+```bash
+$ npm install --save-dev casette
+```
+
+# Getting started
+
+```bash
+$ npm install --save-dev casette
+$ mkdir test
+```
+
+Next in your favourite editor, create `test/test.js`:
+
+```node
+import { Casette as c, assert} from 'casette'
+
+c.describe('Array', function() {
+  c.describe('#indexOf()', function() {
+    c.test('should return -1 when value is not present', function() {
+      assert.equal([1,2,3].indexOf(4), -1)
+    })
+  })
+})
+```
+
+Set up a test script in package.json:
+
+```json
+"scripts": {
+  "test": "mocha"
+}
+```
+
+Then run tests with:
+
+```bash
+$ npm test
+
+
+  test/test.mjs
+    √ Array #indexOf() should return -1 when value is not present
+
+
+  1 passing (3ms)
+```
+
+#  Assertions
+
+Not only does casette allow you to use any assertion library of your own choosing, it also comes with it's own assertion library based on node's default [assert](https://nodejs.org/api/assert.html) with a few extra methods:
+
+ * `assert.notOk(value, [message])`: Assert value is not ok.
+ * `assert.match(value, test, [message])`: Check if value matches RegExp test.
+ * `assert.notMatch(value, [message])`: Check if value does not match RegExp test.
+ * `assert.isFulfilled(promise, [message])`: Assert the promise resolves.
+ * `assert.isRejected(promise, [message])`: Assert the promise gets rejects.
+ 
+ # Asynchronous Code
+
+Casette supports any type of asynchronous code testing. It can either be done by adding a parameter to the function (usually done) that gets called once the tests done but casette also supports promises.
+
+Example of testing using done:
+
+```node
+import { Casette as c, assert} from 'casette'
+
+c.describe('User', function() {
+  c.describe('#save()', function() {
+    c.test('should save without error', function(done) {
+      var user = new User('Luna')
+      user.save(function(err) {
+        if (err) done(err)
+        else done()
+      })
+    })
+  })
+})
+```
+
+Alternatively, just use the done() callback directly (which will handle an error argument, if it exists):
+
+```node
+import { Casette as c, assert} from 'casette'
+
+c.describe('User', function() {
+  c.describe('#save()', function() {
+    c.test('should save without error', function(done) {
+      var user = new User('Luna')
+      user.save(done)
+    })
+  })
+})
+```
+
+Or another alternative is to use promises and return a promise directly:
+
+```node
+import { Casette as c, assert} from 'casette'
+
+c.test('should complete this test', function(done) {
+  return new Promise(function(resolve, reject) {
+    reject(new Error('Uh oh, something went wrong'))
+  }).then(done)
+})
+```
+
+Which works well with `async/await` like so:
+
+```node
+c.test('async test', async function() {
+  let user = await User.find({ username: 'test' })
+  assert.ok(user)
+})
+```
+
+# Api
+
+### c.test(message, func)
+
+Queue up the `func` as a test with the specified message.
+
+### c.describe(message, func)
+
+In case you wanna describe a bunch of tests, you can add them inside `func` and it will have the specified `message` prepended before every test:
+
+```node
+import { Casette as c, assert} from 'casette'
+
+function someFunction() { return true }
+
+c.test('#someFunction()', function() {
+  c.test('should always return true', function() {
+    assert.strictEqual(someFunction(), true)
+    assert.strictEqual(someFunction(), true)
+    assert.strictEqual(someFunction(), true)
+  }).skip()
+})
+```
+
+will output:
+
+```bash
+    √ #someFunction() should always return true
+```
+
+### c.test(...).skip()
+
+You can skip tests easily by adding `.skip()` after the test like so:
+
+```node
+c.test('Skip due to something being broken', function() {
+  BrokenFunction()
+}).skip()
+```
+
+### c.test(...).timeout(dur)
+
+Tests can take a long time. By default, casette will cancel a test if it takes longer than 2 seconds. You can however override this by calling the timeout function after the test with the specified duration in milliseconds like so:
+
+```node
+c.test('This is a really long test', async function() {
+  await DoSomethingForReallyLongTime()
+}).timeout(5000) // 5 seconds
+```
