How to test Executors in Android?

Testing Executors in Android can be crucial for ensuring that your asynchronous tasks run correctly and efficiently. Executors help manage threads and simplify the execution of tasks in a concurrent environment. Below are some examples and techniques for testing Executors in your Android applications.


            import static org.junit.Assert.assertEquals;
            import static org.mockito.Mockito.mock;

            import org.junit.Before;
            import org.junit.Test;
            import java.util.concurrent.ExecutorService;
            import java.util.concurrent.Executors;

            public class ExecutorServiceTest {

                private ExecutorService executorService;

                @Before
                public void setUp() {
                    executorService = Executors.newSingleThreadExecutor();
                }

                @Test
                public void testSubmitTask() throws Exception {
                    final StringBuilder result = new StringBuilder();

                    executorService.submit(() -> {
                        result.append("Task executed");
                    }).get(); // Wait for the task to complete

                    assertEquals("Task executed", result.toString());
                }

                // Ensure to shut down the executor
                @After
                public void tearDown() {
                    executorService.shutdown();
                }
            }
