error ?

This is one of the common issue people face when running testng suites.

Most common reason is conflicting of testng versions. May be there are 2 versions of testng in your classpath , which are causing this issue.

Check your maven dependency from Build path

[Right click on project-->Build Path -->Configure build path --> Maven dependency and check for testng]

if there are 2 version of testng, delete one.

This should solve your problem.

How to get Test Case Detail from testlink using TestLink Java API?

Akash Jain automation testing , testing

Getting test case detail from testlink using API is quite needful when displaying results in Reports.

To get test case related detail you will need testlink-java-api.

Prerequisite:

TestLink-Java-API
Java 1.7 or higher
Maven

Since, TestLink-Java-API depends on mulitple other jars, it ia adviceable to create a Maven project and add the below dependencies in POM.XML

<dependencies>
  <!-- Commons APIs -->
  <dependency>
   <groupId>commons-lang</groupId>
   <artifactId>commons-lang</artifactId>
   <version>2.6</version>
   <type>jar</type>
   <scope>compile</scope>
  </dependency>
  <dependency>
   <groupId>commons-io</groupId>
   <artifactId>commons-io</artifactId>
   <version>2.4</version>
   <type>jar</type>
   <scope>compile</scope>
  </dependency>
  <!-- Logging APIs -->
  <dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>slf4j-simple</artifactId>
   <version>1.7.21</version>
  </dependency>
  <!-- Configuration APIs -->
  <dependency>
   <groupId>commons-configuration</groupId>
   <artifactId>commons-configuration</artifactId>
   <version>1.10</version>
  </dependency>
  <!-- XML-RPC related APIs -->
  <dependency>
   <groupId>org.apache.xmlrpc</groupId>
   <artifactId>xmlrpc-common</artifactId>
   <version>3.1.3</version>
   <type>jar</type>
   <scope>compile</scope>
  </dependency>
  <dependency>
   <groupId>xml-apis</groupId>
   <artifactId>xml-apis</artifactId>
   <version>2.0.2</version>
   <type>jar</type>
   <scope>compile</scope>
  </dependency>
  <dependency>
   <groupId>commons-httpclient</groupId>
   <artifactId>commons-httpclient</artifactId>
   <version>3.1</version>
   <type>jar</type>
   <scope>compile</scope>
  </dependency>
  <dependency>
   <groupId>br.eti.kinoshita</groupId>
   <artifactId>testlink-java-api</artifactId>
   <version>1.9.14-0</version>
  </dependency>
<dependencies>

Use the below code to retrieve Test case description, Steps to execute, Expected results etc. using External test case id.

public void getTestDetailFromTestLink() {
  String testCaseDescription = "", expectedResults = "", steps = "";
  URL url;
  try {
   url = new URL("http://localhost/testlink/lib/api/xmlrpc/v1/xmlrpc.php");

   String devKey = "5062c3fertf9b8886e0edd0ffdf6b14";
   TestLinkAPI api = new TestLinkAPI(url, devKey);
   TestCase tCase = api.getTestCaseByExternalId("P1-46039", 1);

   testCaseDescription = tCase.getSummary();

   List<TestCaseStep> list = tCase.getSteps();
   Iterator<TestCaseStep> itr = list.iterator();
   while (itr.hasNext()) {
    TestCaseStep tcs = itr.next();
    expectedResults = tcs.getExpectedResults();
    steps = tcs.getActions();

   }
  } catch (Exception e) {
   e.printStackTrace();
  }

  System.out.println("Description :"+testCaseDescription);
  System.out.println("Expected Result :"expectedResults);
  System.out.println("Steps to Execute :"+steps);
  
 }

Above code produces the below output.

Description :Verify that on selecting Die Hard Techy from Side menu takes user to blog screen.

Expected Result :User should be navigated to Screen.

Steps to Execute :1.Open DieHardTechy website. 2.Select Die Hard Techy.

How to run two different application on two physical android devices in parallel?

Akash Jain android , Appium

Parallel execution of android applications have become a need now days given that number of test scenarios are higher.

Parallel execution is done to achieve maximum test coverage with minimal time.

Appium provides a way for parallel execution.

To achieve this , we have to do the following steps.

We need to start 2 appium instances on different ports.
Boot strap port numbers for both the instances must be different.
provide the unique identifier of physical devices using -U flag.
If you are trying to run an Hybdrid application in parallel, make sure you start chrome driver on 2 different ports.

You can skip the point 4 if you are automating native android apps.

To start appium server you must have node.js installed or you can use default node executable residing inside appium installation directory.

1. Open a command prompt in admin mode and navigate till main.js file inside appium installation directory.

Main.js is find here:

C:\Program Files (x86)\Appium\node_modules\appium\lib\server

2. run the below commands in different command prompt window.

node main -p 4725 -bp 2293 -U place device 1 UDID--chromedriver-port 6000

node main -p 4724 -bp 2292 -U place device 2 UDID--chromedriver-port 6001

You will see appium server up and running on 2 different ports.

Instance 1

Instance 2

3. Now go to your testng.xml file and pass port number and device name as parameter from your testng.xml suite file.

Please make sure parallel attribute inside <suite> must be set to tests.

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Preserve order test runs" parallel="tests">
   <test name="Test for account settings Mobile" preserve-order="true" >
        <parameter name="appName" value="accounts_582.apk" />
        <parameter name="deviceName" value="HTC Nexus 9" />   
        <parameter name="paramName" value="4724" />     
        <classes>
          <class name="omniauto.tests.Accounts_AndroidTest"></class> 
              <class name="omniauto.tests.AggregatedAccount_Settings"></class> 
              <class name="omniauto.tests.ManualAccountSettings_Test"></class> 
        </classes>
    </test>
    <test name="Test suite for account group setting Mobile" preserve-order="true" >
        <parameter name="appName" value="accountgroupsettings_582.apk" />
        <parameter name="deviceName" value="Samsung I9500 Galaxy S4" />
        <parameter name="paramName" value="4725" />
        <classes>
            <class name="omniauto.tests.Account_Group_Settings"></class>
        </classes>
    </test>
    
</suite>

4. Use that port number in forming your driver instance.

driver = new AppiumDriver(new URL("http://127.0.0.1:"+portNum+"/wd/hub"), capabilities);

Happy learning ! :)
