You will need to import some dependencies for both Spring and Android. Here are the dependencies.

• Spring

To implement the dependency for testing, you need to add the testing dependency in the pom.xml file:

<!-- This is to implement the testing functions for the spring project -->
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-test</artifactId>
   <scope>test</scope>
</dependency>

• Android

To test an Android project, we need to implement the testing dependencies in the gradle file. To add the dependencies, we need to implement in the dependencies {...} of build.gradle (app module) file. Here is a snippet code of this build.gradle file:

// Dependencies for local unit tests
dependencies{
testImplementation "junit:junit:$rootProject.ext.junitVersion"

// Espresso UI Testing dependencies.
androidTestImplementation "com.android.support.test.espresso:espresso-core:$rootProject.ext.espressoVersion"
androidTestImplementation "com.android.support.test.espresso:espresso-contrib:$rootProject.ext.espressoVersion"
androidTestImplementation "com.android.support.test.espresso:espresso-intents:$rootProject.ext.espressoVersion"
}
