+_Note: Once a mixin has been called then the body cannot be reused, thus calling additional mixins on `.body`, e.g. `.body.json(); .body.text()` will result in an error `TypeError: unusable` being thrown and returned through the `Promise` rejection._
+
+Should you need to access the `body` in plain-text after using a mixin, the best practice is to use the `.text()` mixin first and then manually parse the text to the desired format.
+

+### `MockAgent.pendingInterceptors()`
+
+This method returns any pending interceptors registered on a mock agent. A pending interceptor meets one of the following criteria:
+
+- Is registered with neither `.times(<number>)` nor `.persist()`, and has not been invoked;
+- Is persistent (i.e., registered with `.persist()`) and has not been invoked;
+- Is registered with `.times(<number>)` and has not been invoked `<number>` of times.
+
+Returns: `PendingInterceptor[]` (where `PendingInterceptor` is a `MockDispatch` with an additional `origin: string`)
+
+#### Example - List all pending inteceptors
+
+```js
+const agent = new MockAgent()
+agent.disableNetConnect()
+
+agent
+  .get('https://example.com')
+  .intercept({ method: 'GET', path: '/' })
+  .reply(200, '')
+
+const pendingInterceptors = agent.pendingInterceptors()
+// Returns [

+### `MockAgent.assertNoPendingInterceptors([options])`
