 ## Run Your First Test
 
-### Step 1: Upload Your Application
+### Step 1: Create your Android Flutter app and test suite for testing
+For testing, you need to build a Flutter app and test suite. You can create Flutter applications and test suites using either Flutter cli or Gradlew. The steps below demonstrate how to create apks with Gradlew.
+
+- Create an instrumentation test file in your application's directory `android/app/src/androidTest/java/com/example/lambdatestSampleApp/`. Replace **com**, **example**, and **lambdatestSampleApp** values with those from your app's package name. 
+
+  ```java title="SampleTest.java"
+  package com.example.lambdatestSampleApp;
+      import androidx.test.rule.SampleTestRule;
+      import dev.flutter.plugins.integration_test.FlutterTestRunner;
+      import org.junit.Rule;
+      import org.junit.runner.RunWith;
+      import com.example.lambdatestSampleApp.Sample;
+      @RunWith(FlutterTestRunner.class)
+      public class SampleTest {
+        @Rule
+        public SampleTestRule<Sample> rule = new SampleTestRule<>(Sample.class, true, false);
+      }
+  ```
+
+- Update your application's `lambdatestSampleApp/android/app/build.gradle` file to use androidx's version of `AndroidJUnitRunner` and include the `androidx` libraries as dependencies.
+
+  ```java title="build.gradle"
+  android {
+        ...
+        defaultConfig {
+          ...
+          testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
+        }
+      }
+      dependencies {
+          testImplementation 'junit:junit:4.12'
+          androidTestImplementation 'androidx.test:runner:1.2.0'
+          androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
+      }
+   ```
+
+- Use the following `Gradle` commands to build an instrumentation `test.apk` file(test suite) using the `Sample.java` created in the `androidTest` directory as mentioned in step 1.
+
+  ```java title="Terminal"
+  //Go to the android folder which contains the "gradlew" script used for building Android apps from the terminal
+  pushd android
+  //Build an Android test APK (uses the Sample.java file created in step 1)
+  ./gradlew app:assembleAndroidTest
+  //Build a debug APK by passing the integration test file
+  ./gradlew app:assembleDebug -Ptarget="INTEGRATION_TEST_FILE_PATH"
+  //Go back to the root of the project
+  popd
+  ```
