# Asset testing
Elastic Packages define assets to be loaded into Elasticsearch and Kibana. Asset loading tests exercise install a package to ensure that its assets are loaded into Elasticsearch and Kibana as expected.

## Conceptual process

Conceptually, running an asset load test involves the following steps:
1. Build the package.
2. Deploy Elasticsearch, Kibana, and the Elastic Package Registry (all of which are part of the Elastic Stack). This step takes time, so you should typically do it once as a prerequisite to running asset loading tests on multiple packages.
3. Install the package.
4. Use various Kibana and Elasticsearch APIs to confirm that the package assets were loaded into Kibana and Elasticsearch as expected.
5. Remove the package.


## Define an asset loading test

As a package developer, there is no work required to define an asset loading test for your package. All the necessary information is contained in the package files.

## Run an asset loading test

First, you must build your package. This step corresponds to step 1 in the [Conceptual process](#asset-testing-concepts) section.
Navigate to the root folder of the package, or any sub-folder under it, and run the following command.
```bash
elastic-package build
```

Next, deploy Elasticsearch, Kibana, and the Elastic Package Registry. This step corresponds to step 2 in the [Conceptual process](#asset-testing-concepts) section.
```bash
elastic-package stack up -d
```

To view a list of the available options for this command, run `elastic-package stack up -h` or `elastic-package help stack up`.
Next, invoke the asset loading test runner. This step corresponds to steps 3 to 5 in the [Conceptual process](#asset-testing-concepts) section.
Navigate to the root folder of the package, or any sub-folder under it, and run the following command.
```bash
elastic-package test asset
```

Finally, when all the asset loading tests have completed, bring down the Elastic Stack. This step corresponds to step 4 in the [Conceptual process](#asset-testing-concepts) section.
```bash
elastic-package stack down
```
