Introduction to File Sharing Testing on Android

File sharing is a crucial feature in many Android apps, allowing users to share files with others or between apps. However, this feature can be prone to errors, affecting the user experience and app adoption. Common failures include crashes, failed uploads, and security vulnerabilities. To ensure a seamless file sharing experience, thorough testing is essential.

What to Test in File Sharing

The following test cases cover happy path scenarios, error scenarios, edge cases, and accessibility considerations:

• Happy path scenarios:

+ Share a small file (e.g., text file) between two apps

+ Share a large file (e.g., video) between two apps

+ Share a file with multiple recipients

• Error scenarios:

+ Share a file with an invalid recipient (e.g., incorrect email address)

+ Share a file with a recipient who does not have the required app installed

+ Share a file that exceeds the maximum allowed size

• Edge cases:

+ Share a file with a special character in its name

+ Share a file with a very long name

+ Share a file from an external storage device (e.g., SD card)

• Accessibility considerations:

+ Test file sharing with the screen reader enabled (e.g., TalkBack)

+ Test file sharing with the font size increased

+ Test file sharing with the color scheme changed (e.g., high contrast mode)

Manual Testing Approach

To manually test file sharing on an Android app, follow these steps:

1. Prepare test files: Create test files of different types (e.g., text, image, video) and sizes.
2. Install the app: Install the app on a physical Android device or an emulator.
3. Configure the app: Configure the app to allow file sharing (e.g., enable permissions, set up accounts).
4. Share files: Share files between the app and other apps or recipients, using different methods (e.g., email, messaging app).
5. Verify results: Verify that the files are shared correctly, and the recipient can access the files.
6. Test error scenarios: Test error scenarios, such as sharing a file with an invalid recipient or exceeding the maximum allowed size.

Automated Testing Approach

To automate file sharing testing on Android, use tools and frameworks like:

• Appium: Use Appium to automate interactions with the app and simulate file sharing.
• Android UI Automator: Use the Android UI Automator to automate interactions with the app and simulate file sharing.
• Robotium: Use Robotium to automate interactions with the app and simulate file sharing.

Example Appium code snippet:

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;

// Set up the Appium driver
AppiumDriver driver = new AppiumDriver();

// Find the share button
MobileElement shareButton = driver.findElement(By.id("share_button"));

// Click the share button
shareButton.click();

// Find the file to share
MobileElement fileToShare = driver.findElement(By.id("file_to_share"));

// Click the file to share
fileToShare.click();

// Verify the file is shared
Assert.assertTrue(driver.findElement(By.id("shared_file")).isDisplayed());

How SUSA Tests File Sharing Autonomously

SUSA tests file sharing autonomously using its 10 user personas, including:

• Curious: Tests file sharing with different file types and sizes.
• Impatient: Tests file sharing with a slow network connection.
• Elderly: Tests file sharing with accessibility features enabled (e.g., screen reader).
• Adversarial: Tests file sharing with invalid recipients or exceeding the maximum allowed size.

SUSA's cross-session learning feature allows it to get smarter about the app every run, identifying new issues and improving test coverage. SUSA also provides coverage analytics, including per-screen element coverage and untapped element lists, to help developers identify areas for improvement.

Example SUSA test scenario:

By using SUSA to test file sharing autonomously, developers can ensure a seamless file sharing experience for their users, without the need for manual testing or scripting.
