# Testing

This adapter comes with handy test assertions that you can use as you would use normal Masonite routes/views assertions.

### Test Assertions

* assertIsInertia()
* assertInertiaComponent()
* assertInertiaHasProp()
* assertInertiaMissingProp()
* assertInertiaPropsCount()
* assertInertiaVersion()
* assertInertiaRootView()
* withInertia():
  * component()
  * has()
  * hasCount()
  * missing()
  * url()
  * version()
  * dump()
  * dd()

Let's use this route as an example

{% code title="app/http/controllers/EventsController.py" %}

```python
Route.get("/", "ExampleController@show")


class ExampleController(Controller):

    def show(self, view: Inertia):

        return view.render("Events/Show", {
            "events": Event.all().serialize(),
            "keys": [],
            "extra": {
                "a": "b"
                "e": {"hello": "world"}
            },
            custom_root_view="my_app"
        })
```

{% endcode %}

### assertIsInertia()

Assert that the route returned an inertia response.

```python
self.get("/").assertIsInertia()
```

### assertInertiaComponent()

Assert that the given component name is used.

```python
self.get("/").assertIsInertiaComponent("Events/Show")
```

### assertInertiaHasProp(key, value=None)

Assert that the given prop is present in props. The prop value can be asserted too. Nested notations can be used.

```python
self.get("/")
    .assertIsInertiaHasProp("events")
    .assertIsInertiaHasProp("keys", [])
    .assertIsInertiaHasProp("extra.e.hello")
    .assertIsInertiaHasProp("extra.a", "b")
```

### assertInertiaMissingProp(key)

Assert that the given prop is not present in props. Nested notations can be used.

```python
self.get("/")
    .assertInertiaMissingProp("unknown")
    .assertInertiaMissingProp("extra.c")
```

### assertInertiaPropsCount(count)

Assert iterable count for a given prop.

```python
self.get("/")
    .assertInertiaPropsCount("extra", 2)
    .assertInertiaPropsCount("keys", 0)
```

### assertInertiaVersion(version)

Assert inertia assets version is equal to given version.

```python
self.get("/").assertInertiaVersion("123456")
```

### assertInertiaRootView(view)

Assert inertia root view is equal to given view

```python
self.get("/").assertInertiaVersion("my_app")
```

### withInertia()

Assert that the route returned an inertia response and return an inertia testing object to ease further testing assertions.

```python
self.get("/").withInertia()
    .component("Events/Show")
    .has("extra.a", "b")
    .hasCount("keys", 0)
    .url("/")
    .missing("unknown")
    .version("123456")
```

### withInertia().dump()

Dump component name, url, props data and version of the returned response to the console.

### withInertia().dd()

Same as above `dump()` command but will fail and stop the test when executed.
