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.
<journeyname="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></>

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:
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:
Immediately stop journey execution.
Mark the failed step as FAILED.
Mark any subsequent steps as SKIPPED.
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
<journeyname="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>
Example 2: Standard JSON Outcome Report
{"journey":"Login and Profile Edit","results":[{"action":"Verify that the username input field is visible","status":"PASSED","commands":[],"comment":"Username input detected at bounds [100,200][980,300] via UI dump."},{"action":"Tap the username input field","status":"PASSED","commands":["adb shell input tap 540 250"],"comment":"Tapped center coordinates of username input."},{"action":"Type \"testuser\" into the input","status":"PASSED","commands":["adb shell input text \"testuser\""],"comment":"Username typed successfully."},{"action":"Tap the password input field","status":"PASSED","commands":["adb shell input tap 540 370"],"comment":"Tapped center of password input."},{"action":"Type a redacted test password into the input","status":"PASSED","commands":["adb shell input text \"[REDACTED_PASSWORD]\""],"comment":"Password typed successfully. The actual input value was not stored in the report."},{"action":"Tap the \"Login\" button","status":"PASSED","commands":["adb shell input tap 540 500"],"comment":"Login button clicked."},{"action":"Verify that the Home dashboard is visible and user profile photo is shown","status":"FAILED","commands":[],"comment":"Dashboard loaded but profile photo was missing from the UI header."}]}
Best Practices
✅ Calculate Centers for Taps: When parsing element bounds like [x1,y1][x2,y2], always compute the middle coordinate:
$$x_{center} = \frac{x_1 + x_2}{2}, \quad y_{center} = \frac{y_1 + y_2}{2}$$
✅ Include Sleep Buffers: Always add a short delay (e.g., 1-2 seconds) after interactive actions (like button taps) to let layouts and transitions render before executing assertions.
✅ Fail Fast: Stop the test immediately upon encountering the first failure. Continuing after a failure leads to invalid results.
✅ Log Precise Commands Safely: Include non-sensitive raw commands (such as adb shell input tap) in the JSON output list for diagnostics. Redact text entered into password, OTP, token, payment, or personal-data fields; never persist the literal secret in reports, CI logs, or shared artifacts.
Limitations
The parser only evaluates the static screen hierarchy (e.g. uiautomator dump). Elements that require scrolling are marked as not visible unless a scrolling action is explicitly performed.
Non-standard UI components (like custom OpenGL canvas views) cannot be read via standard accessibility trees and may require screenshot analysis or hardcoded click maps.
Key events and text typing via ADB do not trigger standard soft keyboard events on all emulator images, which can lead to input validation issues.
