The `testing` package provides functions for testing Flux operations.
Import the `testing` package:

```js
import "testing"
```



## Options

```js
option testing.load = (tables=<-) => tables

option testing.tags = []
```
 
### load

`load` loads test data from a stream of tables.


### tags

`tags` is a list of tags that will be applied to a test case.

The test harness allows filtering based on included tags.

 Tags are expected to be overridden per test file and test case
 using normal option semantics.
