Android Espresso Dependencies

Adds Espresso and AndroidX Test dependencies required for E2E UI testing.

Prerequisites

• Android project with Gradle
• Kotlin DSL (build.gradle.kts)
• Minimum SDK 21+ (Espresso requirement)

Inputs

Input	Required	Default	Description
project_path	Yes	.	Android project root

Process

Step 1: Add Espresso Dependencies

Add to

app/build.gradle.kts

:

dependencies {
    // Existing dependencies...

    // Espresso core
    androidTestImplementation("androidx.test.espresso:espresso-core:3.5.1")
    androidTestImplementation("androidx.test.espresso:espresso-contrib:3.5.1")
    androidTestImplementation("androidx.test.espresso:espresso-intents:3.5.1")

    // AndroidX Test
    androidTestImplementation("androidx.test:runner:1.5.2")
    androidTestImplementation("androidx.test:rules:1.5.0")
    androidTestImplementation("androidx.test.ext:junit:1.1.5")
    androidTestImplementation("androidx.test.ext:junit-ktx:1.1.5")
}

Detection logic:

• Check if dependencies already exist (don't duplicate)
• Use latest stable versions
• Keep existing test dependencies

Step 2: Configure Test Runner (Optional)

If user wants test orchestrator for better isolation:

android {
    // ... existing config ...

    defaultConfig {
        // ... existing config ...
        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
    }

    testOptions {
        execution = "ANDROIDX_TEST_ORCHESTRATOR"
        animationsDisabled = true
    }
}

dependencies {
    // ... existing dependencies ...
    androidTestUtil("androidx.test:orchestrator:1.4.2")
}

Ask user: "Enable test orchestrator for better test isolation? (Recommended for large test suites)"

Verification

MANDATORY: Run these commands:

# Sync Gradle
./gradlew dependencies --configuration androidTestRuntimeClasspath

# Verify Espresso dependencies
./gradlew dependencies | grep espresso && echo "✓ Espresso dependencies added"

# Verify AndroidX Test dependencies
./gradlew dependencies | grep "androidx.test" && echo "✓ AndroidX Test dependencies added"

Expected output:

• ✓ Espresso dependencies added
• ✓ AndroidX Test dependencies added

Outputs

Output	Location	Description
Dependencies	app/build.gradle.kts	Espresso and AndroidX Test libs

Troubleshooting

"Dependency resolution failed"

Cause: Version conflict with existing dependencies Fix: Check for conflicting androidx.test versions, align all to same version

"Minimum SDK too low"

Cause: minSdk < 21 Fix: Espresso requires API 21+, update minSdk in defaultConfig

Completion Criteria

• Espresso dependencies in app/build.gradle.kts
• AndroidX Test dependencies in app/build.gradle.kts
• Test runner configured

• ./gradlew dependencies
