How to find app Launcher activity name in Appium

We have two options for find app activity name

1) By using Command Prompt
2) Manifest Info
3) Hierarchy Viewer


1) By using Command Prompt

Please find below steps to find app activity name using command prompt.


-> app APK package name. EX : com.android.calculator2

-> Launch the Android Emulator and wait till starts properly.

-> Goto command prompt and goto E:\android-sdks\platform-tools and verify the device connected properly (not offline). by using below command

E:\SDK\platform-tools>adb devices

List of devices attached
emulator-5554   device

-> Open the reuired app and keep on active in Emulator

-> GOTO and command prompt and use below commands

E:\android-sdks\platform-tools>adb logcat >log.txt

-> Now its generated log text file. Here you can search by app Package name (com.android.calculator2) then we will have log like

I/ActivityManager(  878): Displayed com.android.calculator2/.Calculator: +7s332ms


Here com.android.calculator2.Calculator is app activity name.



2) By using AndroidManifest.xml Info



http://software-testing-tutorials-automation.blogspot.in/2015/10/find-launcher-activity-and-package-name.html


-> Right click on .apk file of APK Info app(or any other .apk file for which you wants to know package and activity name).

-> Select Open with -> WinRAR archiver option from right click context menu.

-> It will open .apk file in WinRAR window and you can see AndroidManifest.xml.

-> Open AndroidManifest.xml file in notepad. Now find keyword "p a c k a g e" In notepad.

-> Package name for my APK Info app is : com.intelloware.apkinfo Find keyword "a c t i v i t y" In notepad. It will show you activity name of your app.


-> Activity name for my APK Info app is display: .MainActivity. Here you need to append package name ahead of activity name so full activity name is : com.intelloware.apkinfo.MainActivity



3) Hierarchy Viewer 


-> Launch the Android Emulator and wait till starts properly.

-> Launch the appium and start the server.

-> Open the Hierarchy viewer from below path. Android Emulator should be starts properly, its should not be closed.

how to break out of nested loops java

break;

By using break we can come out from single loop.

But if we want to come out from all nested loop then we shoule use lables for acheiving this concept.



Example:

int points = 0;
int goal = 100;
someLabel:
while (goal <= 100) {
   for (int i = 0; i < goal; i++) {
      if (points > 50) {
         break someLabel;
      }
   points += i;
   }
}
// you are going here after break someLabel;

Build failed





2) Configure XSLT and build.xml


-> The below jar files shoule be under lib folder

* saxon-8.7
* SaxonLiaison
* testng-xslt-maven-plugin-test-0.0
* Selenium-server-standalone 2.47

-> The below files should be under project path

* build.xml  -> Link to download
* testng-results.xsl -> Link to Download

-> Configure build.xml file

• Verify the Value for "project.jars" property at line no 10 of build.xml file. It should be the path of "lib" folder of project.
• Verify the path of testng-results.xsl file at line no 91 of build.xml file. It should be  path of testng-results.xsl.

Note : Don't change any thing else In build.xml file.




3) Genrate XSLT report by using ANT


Once your test execution get completed and testng results generated, We can go to generate XSLT report. You need to follow bellow given steps to generate XSLT report.


-> Open command prompt.

-> Goto your project

E:\Selenium_Project\Selenium_Testing>

-> Type "ant" to check we are in correct path to generate XSLT report.


E:\Selenium_Project\Selenium_Testing>ant
Buildfile: E:\Selenium_Project\Selenium_Testing\build.xml

usage:
     [echo]
     [echo]             ant run will execute the test
     [echo]

BUILD SUCCESSFUL
Total time: 0 seconds


-> Remove Previous Build : Type Command = "ant clear"

 It should give message "BUILD SUCCESSFUL"


E:\Selenium_Project\Selenium_Testing>ant clear
Buildfile: E:\Selenium_Project\Selenium_Testing\build.xml

clear:
   [delete] Deleting directory E:\Selenium_Project\Selenium_Testing\build

BUILD SUCCESSFUL
Total time: 0 seconds


-> Compile And Generate New Build Folder : Type Command = "ant compile".

 It should give message "BUILD SUCCESSFUL"

E:\Selenium_Project\Selenium_Testing>ant compile


-> Verify Build Folder Is Generated : Now Refresh your project In eclipse.
 ant compile command will created new folder with name of  build under your project

-> Execute Test Suites : Type Command = ant run In command prompt and press enter.
It will execute your all software automation test suites which are included In testng.xml file.

 So now you can execute your software test suites from command prompt Instead of testng.xml file.

-> Generate XSLT Reports : Type Command = ant reports In command prompt and press enter.
It should give message "BUILD SUCCESSFUL"

-> open XSLT Report : Once more refresh your project In eclipse.

 ant reports command will create new folder with name = XSLT_Reports under your project


->You will find index.html file In XSLT_Reports folder.
That Is XSLT Report of your webdriver test. Open that file In any web browser.
 It Is Interactive and easy to understand that how many test cases are Pass, Fail and Skip for specific test case.



Note : If pie chart is not available in your report then you will get error message in browser like below


Error Message : SVG Pie Charts are not available. Please install a SVG viewer for your browser


So please install SVG viewer in order to see pie chart in XSLT reports.
