# expect package

-   Flux 0.14.0+
-   View InfluxDB support

The `expect` package includes functions to mark any expectations for a testcase to be satisfied before the testcase finishes running. Import the `testing/expect` package:

```js
import "testing/expect"
```

These functions are intended to be called at the beginning of a testcase, but it doesn’t really matter when they get invoked within the testcase.

## Functions

-   [expect.planner()](/flux/v0/stdlib/testing/expect/planner/)
