# Installing the Test Toolkit

There are several options for installing the Test Toolkit in a Microsoft Dynamics 365 Business Central container. Which option is available to you depends on whether you are creating a new container or you already have one up and running.

### Include Test Toolkit on container creation

The Test Toolkit can be included upon creation of your container through the [BcContainerHelper](https://github.com/microsoft/navcontainerhelper) PowerShell Module.

There are three switches that you can set in order to control which parts of the Test Toolkit will be installed:

* `-includeTestToolkit` is the main switch and is required to enable the installation of the Test Toolkit. If specified alone it will cause a full install of the Test Toolkit which also includes Microsofts test suites.
    
* `-includeTestFrameworkOnly` will only install the Test Framework. The Test Framework contains the required dependencies for developing automated tests.
    
* `-includeTestLibrariesOnly` will install the Test Framework including a wide selection of libraries created by Microsoft.
    

Here is an example of how to create a container with the Test Toolkit included:

```plaintext
$username = "admin"
$password = ConvertTo-SecureString "#LetMeIn123" -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential($username, $password)
$artifactUrl = Get-BCArtifactUrl
New-BcContainer "AUTOMATEDTESTS" -artifactUrl $artifactUrl -Credential $credential -updateHosts -accept_eula -includeTestToolkit -includeTestFrameworkOnly
```

### Install the Test Toolkit on an existing container

When you already have a container running but want to start using the Test Toolkit you can install it with the [BcContainerHelper](https://github.com/microsoft/navcontainerhelper) PowerShell Module.

Running the command `Import-TestToolkitToBcContainer` command will install the Test Toolkit in the specified container.

It is also possible to specify the `-includeTestFrameworkOnly` and `-includeTestLibrariesOnly` switches as mentioned above.

Here is an example of how to install the Test Toolkit in an existing container:

```plaintext
Import-TestToolkitToBcContainer "AUTOMATEDTESTS" -includeTestLibrariesOnly
```
