|
A mock client class that implements the same api as [MockPool](MockPool.md).
|
||
|
|
|
||
|
|
## `new MockClient(origin, [options])`
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
* **origin** `string` - It should only include the **protocol, hostname, and port**.
|
||
|
|
* **options** `MockClientOptions` - It extends the `Client` options.
|
||
|
|
|
||
|
|
Returns: `MockClient`
|
||
|
|
|
||
|
|
### Parameter: `MockClientOptions`
|
||
|
|
|
||
|
|
Extends: `ClientOptions`
|
||
|
|
|
||
|
|
* **agent** `Agent` - the agent to associate this MockClient with.
|
||
|
|
|
||
|
|
### Example - Basic MockClient instantiation
|
||
|
|
|
||
|
|
We can use MockAgent to instantiate a MockClient ready to be used to intercept specified requests. It will not do anything until registered as the agent to use and any mock request are registered.
|
||
|
|
|
||
|
|
```js
|
||
|
|
import { MockAgent } from 'undici'
|
||
|
|
|
||
|
|
// Connections must be set to 1 to return a MockClient instance
|
||
|
|
const mockAgent = new MockAgent({ connections: 1 })
|
||
|
|
|
||
|
|
const mockClient = mockAgent.get('http://localhost:3000')
|
||
|
|
```
|
||
|
|
|
||
|
|
