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
Nested Flows
Constants defined in a nested flow override parameters with the same name in the parent flow.
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.
