This PR implements comprehensive UI tests for the MVI Coroutines Flow Android application using the Espresso testing framework. The tests cover all major user interactions, form validation, navigation flows, and error handling scenarios.

📱 Test Coverage

Core Functionality Tests

MainActivity: User list display, pull-to-refresh, menu navigation, swipe-to-delete
AddActivity: Form validation, text input handling, error states
SearchActivity: Search functionality, results display, search view interactions
Navigation: Intent-based navigation verification between activities
Integration: End-to-end user workflows and complete user journeys

UI Components Tested

✅ RecyclerView with user list interactions
✅ SwipeRefreshLayout pull-to-refresh gestures
✅ TextInputLayout form fields and validation
✅ SearchView in ActionBar with query handling
✅ Material buttons, progress indicators, and error states
✅ Navigation drawer/menu interactions
✅ Intent verification for activity transitions

🎯 Test Examples

Form Validation Testing

@TestfunaddActivity_showsValidationErrors_forInvalidEmail() {  onView(withId(R.id.emailEditText))    .perform(typeText("invalid-email"))    onView(withId(R.id.addButton))    .perform(click())// Validation error handling is verified}

Navigation Testing

@TestfunnavigateToAddActivity_fromMenu() {  openActionBarOverflowOrOptionsMenu(context)  onView(withText("Add")).perform(click())    intended(hasComponent(AddActivity::class.java.name))}

Integration Testing

@TestfunendToEndFlow_addUser() {// Navigate to Add → Fill form → Return to main// Tests complete user workflow}

🔧 Technical Notes

UsesActivityScenarioRule for proper activity lifecycle management
Implements Intent verification for navigation testing
Includes comprehensive error state and loading indicator testing
Follows Android testing best practices with proper isolation
Compatible with CI/CD pipeline execution

✅ Benefits
