# Unit Testing
|
||||
|
||||
The unit test checks the result of formatted payload and the constraints.
|
||||
|
||||
```bash
|
||||
|
||||
npm test
|
||||
|
||||
```
|
||||
|
||||
# The API
|
||||
|
||||
## `Cloudevent` class
|
||||
|
||||
```js
|
||||
|
||||
/*
|
||||
* Format the payload and return an Object.
|
||||
*/
|
||||
Object Cloudevent.format()
|
||||
|
||||
/*
|
||||
* Format the payload as String.
|
||||
*/
|
||||
String Cloudevent.toString()
|
||||
|
||||
```
|
||||
|
||||
## `Formatter` classes
|
||||
|
||||
Every formatter class must implement these methods to work properly.
|
||||
|
||||
```js
|
||||
|
||||
/*
|
||||
* Format the Cloudevent payload argument and return an Object.
|
||||
*/
|
||||
Object Formatter.format(payload)
|
||||
|
||||
/*
|
||||
* Format the Cloudevent payload as String.
|
||||
*/
|
||||
String Formatter.toString(payload)
|
||||
|
||||
```
|
||||
|
||||
## `Spec` classes
|
||||
|
||||
Every Spec class must implement these methods to work properly.
|
||||
|
||||
```js
|
||||
|
||||
/*
|
||||
* The constructor must receives the Cloudevent type.
|
||||
*/
|
||||
Spec(Cloudevent)
|
||||
|
||||
/*
|
||||
* Checks the spec constraints, throwing an error if do not pass.
|
||||
*/
|
||||
Spec.check()
|
||||
|
||||
```
|
||||
## `Binding` classes
|
||||
|
||||
Every Binding class must implement these methods to work properly.
|
||||
|
||||
```js
|
||||
|
||||
/*
|
||||
* The constructor must receives the map of configurations.
|
||||
*/
|
||||
Binding(config)
|
||||
|
||||
/*
|
||||
* Emits the event using an instance of Cloudevent.
|
||||
*/
|
||||
Binding.emit(cloudevent)
|
||||
|
||||
```
|
||||
|
||||
# How to use
|
||||
|
||||
The `Cloudevent` constructor arguments.
|
||||
|
||||
```js
|
||||
|
||||
/*
|
||||
* spec : if is null, set the spec 0.1 impl
|
||||
* format: if is null, set the JSON Format 0.1 impl
|
||||
*/
|
||||
Cloudevent(spec, format);
|
||||
|
||||
```
|
||||
|
||||
## How to construct instances?
|
||||
|
||||
```js
|
||||
/*
|
||||
* Constructs a default instance with:
|
||||
* - Spec 0.1
|
||||
* - JSON Format 0.1
|
||||
*/
|
||||
var cloudevent01 = new Cloudevent();
|
||||
|
||||
/*
|
||||
* Implemented using Builder Design Pattern
|
||||
*/
|
||||
cloudevent01
|
||||
.type("com.github.pull.create")
|
||||
.source("urn:event:from:myapi/resourse/123");
|
||||
|
||||
/*
|
||||
* Backward compatibility by injecting methods from spec implementation to Cloudevent
|
||||
*/
|
||||
cloudevent01
|
||||
.eventTypeVersion("1.0");
|
||||
|
||||
/*
|
||||
* Constructs an instance with:
|
||||
* - Spec 0.2
|
||||
* - JSON Format 0.1
|
||||
*/
|
||||
var cloudevent02 = new Cloudevent(Cloudevent.specs['0.2']);
|
||||
|
||||
/*
|
||||
* Different specs, but the same API.
|
||||
*/
|
||||
cloudevent02
|
||||
.type("com.github.pull.create")
|
||||
.source("urn:event:from:myapi/resourse/123");
|
||||
|
||||
```
|
||||
|
||||
## How to get the formatted payload?
|
||||
|
||||
```js
|
||||
var cloudevent = new Cloudevent()
|
||||
.type("com.github.pull.create")
|
||||
.source("urn:event:from:myapi/resourse/123");
|
||||
|
||||
/*
|
||||
* Format the payload and return it.
|
||||
*/
|
||||
var formatted = cloudevent.format();
|
||||
|
||||
```
|
||||
|
||||
## How to emit an event?
|
||||
|
||||
```js
|
||||
// The event
|
||||
var cloudevent = new Cloudevent()
|
||||
.type("com.github.pull.create")
|
||||
.source("urn:event:from:myapi/resourse/123");
|
||||
|
||||
// The binding configuration using POST
|
||||
var config = {
|
||||
method: 'POST',
|
||||
url : 'https://mywebhook.com'
|
||||
};
|
||||
|
||||
// The binding instance
|
||||
var binding = Cloudevent.bindings['http-structured0.1'](config);
|
||||
|
||||
// Emit the event using Promise
|
||||
binding.emit(cloudevent)
|
||||
.then(response => {
|
||||
// Treat the response
|
||||
console.log(response.data);
|
||||
|
||||
}).catch(err => {
|
||||
// Treat the error
|
||||
console.error(err);
|
||||
});
|
||||
```
