How to log test cases in Android Studio

Logging test case results is as important as writing test cases. There are many ways to log the results provided by JUnit but I am going to provide a simple and effective solutions which I adopted to Log Test case results on Android Studio.This method is independent of selection of automation tool. 

It is also a good practice to take a screenshot from the device when test case fails but that code is tool dependent so I will share that too in future posts.

The way you log your test case results will simplify tracking of bugs and generate a proper report as output of your Test Suit Run.Hence I suggest you to start Logging your test case results starting from your very first test case.

Let us see with simple example.

1. Create a Java Class names TestCases in the Android Studio.
2. Declare a Tag in the class as String LoginTestCase.
3. Then write the log on sucess or failure as per you like as shown in below test case. I have added Appium test case as sample but this you can use in any of your Test Cases.

public void TestCase
AppiumDriver driver;
String Tag_name="ScrollTestCase";
    public void testCaseSetup()throws  Exception

        DesiredCapabilities cap=new DesiredCapabilities();
        cap.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
        cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Android device");
        cap.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, "4000");
        cap.setCapability(MobileCapabilityType.APP, "c://apks//seekbarsample.apk");
        cap.setCapability("noReset", true);
        driver = new AndroidDriver(new URL(""), cap);


    public void testVerticalScroll()
        //Scroll till the 25th row
        driver.scrollTo("List item:25");
        //Click on the 25th row text
        driver.findElement(By.name("List item:25")).click();
        try {
            Log.e(Tag_name,"Test case passes");
            Assert.assertEquals("Clicked on row no: 25", driver.findElement(By.id("row_select")).getText());
        }catch (AssertionError e)
            Log.e(Tag_name,"Test case failed")
    public void testCaseTearDown()

4. Once you are done adding adding log in each test case ten run the test suite.
5. Then click on Android Monitor at the  and it will open the Monitor as shown in below screenshot

6. Then click on Edit Filter Configuration as shown below.

7.Enter Filer name and our Tag name hit OK.

8. Then you can read your test case logs.
