Android UI Journey Testing

Overview

This skill outlines the standard workflow for running XML-specified User Journey tests on Android applications. A "journey" is a sequenced set of user actions and state assertions designed to verify end-to-end functionality. The journey XML acts as the source of truth for the app's behavior. The executor proceeds sequentially, performing UI interactions, checking state assertions, and writing a standardized JSON outcome report.

When to Use

• Use when evaluating an Android application's UI behavior against an XML test specification.
• Use when automating multi-step user flows (e.g., login, checkout, navigation) and verifying expectations.
• Use when running verification tests and generating standardized JSON test reports.
• Use when debugging application flows on physical devices or emulators using ADB commands.

How It Works

graph TD
    A[Parse Journey XML] --> B[Execute Action / Interaction]
    B --> C{Success?}
    C -- Yes --> D[Verify State Expectation / Assertion]
    C -- No/Crash --> G[Mark FAILED & Exit]
    D -- Passed --> E{More Steps?}
    D -- Failed --> G
    E -- Yes --> B
    E -- No --> F[Output JSON Summary]

Step 1: Parse the Journey Specification

Read and parse the XML test suite structure. The root node <journey> defines the test case name, and the <actions> block contains the sequence of test steps.

<journey name="Search and Cart Flow">
   <description>Verify that searching for an item and adding it to the cart succeeds.</description>
   <actions>
      <action>Search for soda</action>
      <action>Tap the first search result</action>
      <action>Verify that the product detail screen is shown</action>
   </actions>
</journey>

Step 2: Sequential Step Evaluation

Process each <action> element in the exact order specified. Test steps are classified into two groups:

A. Interactive Actions (Taps, Swipes, Text Input)

Perform the physical UI interaction using ADB.

• Tapping: Tap the center of the target element's bounds:

  adb shell input tap <x> <y>
  

• Swiping/Scrolling: Swipe from coordinate to coordinate with a duration:

  adb shell input swipe <x1> <y1> <x2> <y2> <duration_ms>
  

• Text Typing: Type text into the active input field:

  adb shell input text "<string>"
  

If the element is missing or the action cannot be performed, the action and the journey fail.

B. State Assertions (Expectation Verification)

Steps beginning with "verify", "check", or "ensure" represent state assertions.

• Inspect the current screen (using screenshots or uiautomator dump) without interacting or scrolling.
• Confirm all sub-assertions are met. For example, "Verify that the app is on the Home screen and the logo is visible" fails if the home screen is not displayed or the logo is missing.

Step 3: Handle Failures and Crashes

If the application crashes, exits, freezes, or fails an assertion:

1. Immediately stop journey execution.
2. Mark the failed step as FAILED.
3. Mark any subsequent steps as SKIPPED.
4. Document the exact reason for failure.

Step 4: Generate JSON Report

Format the execution results into a standardized JSON schema and write it to the output log.

Examples

Example 1: Full Journey XML Specification

<journey name="Login and Profile Edit">
   <description>Logs into the app, navigates to settings, and changes user profile information.</description>
   <actions>
      <action>Verify that the username input field is visible</action>
      <action>Tap the username input field</action>
      <action>Type "testuser" into the input</action>
      <action>Tap the password input field</action>
      <action>Type a redacted test password into the input</action>
      <action>Tap the "Login" button</action>
      <action>Verify that the Home dashboard is visible and user profile photo is shown</action>
   </actions>
</journey>
