# Gradle dependencies

If you want to expand the current project and include MVVM pattern, which is already in place through the packages, it is necessary to add the following dependencies in the file [`app/build.gradle.kts`](app/build.gradle.kts):

``` bash

dependencies {

    // Plataforma de versions Compose

    implementation(platform("androidx.compose:compose-bom:2024.04.01"))

    implementation(platform(libs.androidx.compose.bom))

    androidTestImplementation(platform(libs.androidx.compose.bom))

    // ────────────────────────────────

    // Unit Testing (JVM)

    // ────────────────────────────────

    testImplementation("androidx.arch.core:core-testing:2.2.0")

    testImplementation(libs.junit)

    // ────────────────────────────────

    // Instrumental UI Testing (emulador/dispositiu)

    // ────────────────────────────────

    androidTestImplementation("androidx.test.espresso:espresso-core")

    androidTestImplementation("androidx.test.ext:junit")

    androidTestImplementation("androidx.compose.ui:ui-test-junit4")

    androidTestImplementation(libs.androidx.espresso.core)

    androidTestImplementation(libs.androidx.junit)

    androidTestImplementation(libs.androidx.ui.test.junit4)

    // ────────────────────────────────

    // Debug Tools (només en debug)

    debugImplementation("androidx.compose.ui:ui-tooling")

    debugImplementation("androidx.compose.ui:ui-test-manifest")

    debugImplementation(libs.androidx.ui.tooling)

    debugImplementation(libs.androidx.ui.test.manifest)
