Parameters & Constants

External parameters

There might be cases where you don't want to store certain values in a test file itself (i.e. user name, password, etc.). To solve that, you can pass parameters to Maestro:

maestro test -e [email protected] -e PASSWORD=123 file.yaml

And then refer to them in your flow using ${name} notation:

appId: your.app.id
---
- launchApp
- inputText: ${USERNAME}
- tapOn: Next
- inputText: ${PASSWORD}

In a similar fashion, parameters can be passed to maestro cloud command:

maestro cloud -e [email protected] PASSWORD=123 app.apk file.yaml

Inline parameters

Constants can be declared at the flow file level, above the --- marker:

appId: your.app.id
env:
    USERNAME: [email protected]
    PASSWORD: 123
---
- inputText: ${USERNAME}
- inputText: ${PASSWORD}

Alternatively, they can be passed to a runFlow command:

appId: your.app.id
---
- runFlow:
    file: subflow.yaml
    env:
      USERNAME: [email protected]
      PASSWORD: 123

{% content-ref url="nested-flows.md" %} nested-flows.md {% endcontent-ref %}

{% hint style="info" %} Constants defined in a nested flow override parameters with the same name in the parent flow. {% endhint %}

Accessing variables from the shell

Maestro will automatically read environment variables from the shell prefixed by MAESTRO_ and make them available in your Flows, assuming the environment variable is not manually defined in the Flow or passed as an env parameter.

export MAESTRO_FOO=bar

If you define the variable MAESTRO_FOO as above, you can simply refer to it in your Flows when running maestro test or maestro cloud like a normal environment variable:

- tapOn: ${MAESTRO_FOO}

Parameters and JavaScript

All env parameters are defined as JavaScript variables under the hood and can be accessed from the JavaScript code.

{% content-ref url="javascript/" %} javascript {% endcontent-ref %}
