How To Use Appium Inspector For Mobile Apps

Let’s put it short: Appium Desktop = Appium Server + Inspector. When Appium Server runs automation test scripts, Appium Inspector can identify the UI elements of every application under test. The core structure of an Appium Inspector is to ensure that you discover every visible app element when you develop your test scripts. Before you kickstart your journey with Appium Inspector, you need to understand the details of it.

In this article on Appium Inspector, let’s cover what Appium Inspector is, why choose it, its pros, what are the specifications of Appium Inspector, how to integrate Appium Inspector, and much more.

Introduction to Appium Inspector

Appium Inspector is the most comprehensive tool for managing tasks such as script recording and element discovery. This tool comes in handy when you want to automate a new app. This is known to be a standard procedure for identifying the mobile app’s unique UI elements. The tool has been under maintenance for Windows and OS X.

All you need to do is download Appium Inspector and install it, for which both Windows and OS X versions (.app and .exe) are available.

Why choose Appium Inspector?

Appium Inspector is a boon for testers wanting to identify UI elements of a mobile app. We can download Appium Inspector and use it to manage the following tasks:

• Get a thorough idea of the element hierarchy: Developers can feel this is just the tip of the iceberg, but it means the iceberg itself for testers. It provides developers with the right information on how to align certain UI elements with each other and also on what different fragments/layers are present in the app.

• Find the attributes: Appium Inspector is used for finding the name, value, description, and different object/element attributes. Objects consist of certain identifiable characteristics which we can identify through the tool. It would then be used directly for the XPath command.

• Record manual app actions: Appium Inspector lets you record different app actions manually to access hierarchy and elements and record them to ensure clear test scripts for the app.

Getting started with Appium Inspector

The below image is the core architecture of the Appium request flow. It’s important to know this before you venture on to know how to use Appium Inspector. When the client requests the Appium server to provide a set of commands, the Appium Inspector identifies the mobile app elements included in it. It uses a set of attributes to identify the elements before it reaches the target system. This is when the user would be able to perform the action they had intended to perform.

Appium inspection process is used to identify or locate mobile app elements. When you need to automate any mobile app scenario, you can follow these steps:

With Appium Inspection, you can get the first step sorted out. For example, let’s say that your app consists of signups. The next step would be to enter your username and password. The Appium inspection process can let you “inspect” your screen and identify the unique text fields. This is the way through which you can enter the username and password in the right fields.
