# Creating a Test - Mobile

For mobile configuration instructions - please refer to [Mobile Installation Guide](/download-installation-start/download-and-installation/mobile-installation.md).

In this guide we will be using the following test scenario to demonstrate how to develop a simple test script:

1. Launch Calculator application.
2. Enter 2x2.
3. Validate that the result is 4.

## Basic Script <a href="#basic-script" id="basic-script"></a>

Oxygen provides a number of built-in objects (modules) for automation purposes. Because in our sample scenario we want to automate only mobile application interactions, we will use the `mob` module. Refer to API Reference for a complete list of provided modules and methods.

1. Launch Calculator application.

   ```javascript
   var caps = {
       platformName: "Android",
       platformVersion: "9.0.1",
       deviceName: "934a9e01",
       appPackage: "com.android.calculator2",
       appActivity: "com.android.calculator2.Calculator",
   };
   mob.init(caps);
   ```

   In the above example , the fields 'AppPackage' and 'AppActivity' are depending on the type of phone you are using, some phones will have different path to their Calculator application. `init` command expects to receive capabilties object defining the application we would like to launch as well as the device specification.
2. Type 2x2

   ```javascript
   mob.click('desc=2');
   mob.click('desc=multiplication');
   mob.click('desc=2');
   ```

   `click` performs tap on an element defined by a locator which will. See API Reference for a list of supported locators.
3. Validate result is 4.

   ```javascript
   mob.assertText('class=android.widget.EditText', '4');
   ```

Entire script:

```javascript
var caps = {
    platformName: "Android",
    platformVersion: "4.2",
    deviceName: "934a9e01",
    appPackage: "com.sec.android.app.popupcalculator",
    appActivity: "com.sec.android.app.popupcalculator.Calculator"
};
mob.init(caps);
mob.click('desc=2');
mob.click('desc=multiplication');
mob.click('desc=2');
mob.assertText('class=android.widget.EditText', '4');
```

Now open a new script in the IDE and paste the above snippet into it. Save the file as `calculator.js`. Switch to the mobile mode by clicking phone icon, select the device on which to run the test from the dropdown menu, and click Run.
