TestNG POM

Problem :

nable to locate the Javac Compiler in:
  C:\Program Files (x86)\Java\jre6\..\lib\tools.jar
Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
In most cases you can change the location of your Java
installation by setting the JAVA_HOME environment variable.


How to solve :  Add this line   fork -> true

Testlink Installation Problems


1. problem 
To solve Maximum Session Idle Time before Timeout  and Checking max. execution time (Parameter max_execution_time) errors in TestLink we need to edit php.ini file.

max_execution_time=3000
session.gc_maxlifetime=60000

2. problem

$tlCfg->log_path = 'E:\xampp\htdocs\testlink\logs'; /* unix example */
$g_repositoryPath = 'E:\xampp\htdocs\testlink\upload_area';  /* unix example */

Testlink Workflow



  • Login in Test link.
  • Create the Project and enable the requirement functionality option.
  • Create the Test case.
  • Create the Requirement.
  • Map the Requirement with Test case using Assign Requirement.
  • Create key word using Keyword Management and assign key word at module level or Test case level (Optional).
  • Create the Test Plan.
  • Add the Test case to Test Plan.
  • Assign the Test case from Test Plan.
  • Create the Build for the Test plan using Build Management.
  • Login as Executer and start executing the Test cases.
  • Go to Report and view all the available Report

Selenium Grid - Hub & Node Configuration

First you need to download selenium-server-standalone-2.41.0 jar file



Use this command from command prompt java -jar selenium-server-standalone-2.41.0.jar

Hub started as you can see from above picture

Open browser http://localhost:4444/   you should see below screen



Now I want to configure node in the same machine


Open another command prompt and you need to specify some  parameters  (as node)

Why We use Page Objects for Selenium

Why use page objects?
  • Maintenance
  • Readability of scripts
  • Reduced or eliminated duplication
  • Reusability

Some Advantages : 

- Separation between test code and locators
- Class acts as an interface to actual page of application
- You can use methods of page object whenever you want to interact with GUI

 Location:
org.openqa.selenium’   ----->    org.openqa.selenium.support.PageFactory  


@FindyBy :  You can either use this annotation by specifying both "how" and "using" or by specifying one of the location strategies (eg: "id") with an appropriate value to use.

@CacheLookup : annotation is being used to eliminate the searching of the web element every time an action is performed

Git Basics

If you’re starting to track an existing project in Git, you need to go to the project’s directory and type

$ git init
 
This creates a new subdirectory named .git 
 
At this point, nothing in your project is tracked yet.  

 Cloning an Existing Repository

You clone a repository with git clone [url].

For example: 

$ git clone git://github.com/schacon/grit.git

  5. Now you are ready to use the testLink.















Jmeter tests in non-GUI mode

Why we need to use non gui mode ? 

One of the way to resolve java.lang.OutOfMemoryError is by running Jmeter in non-gui-mode. 

First prepare your test plan with Jmeter and save it, let's say the file name is 'script.jmx'.


Second Apache JMETER_HOME/bin folder using command shell. And then run Jmeter with the following parameters, to execute the test.


Command :

jmeter -n -t C:\TestScripts\script.jmx -l C:\TestScripts\scriptresults.jtl















-n [This specifies JMeter is to run in non-gui mode]
-t  [name of JMX file that contains the Test Plan]
-l  [name of JTL file to log sample results to]
-j  [name of JMeter run log file].


Test is running the results will be saved in the 'mytest_results.jtl'

Web Service Performance Metrics


• Server Side: can be gathered by stress testing on the server end.
Important parameters are:
Server throughput (measured as the number of requests per second)
Latency (time taken between the service request arriving and the request being serviced.)

Client Side: client side monitoring or distributed load testing can be used to gather data. Important parameters are:
Latency (WS processing time + network latency). This is the time taken for a service call to return the earliest response bytes
Throughput (the average byte flows per unit of time, including latency)
Error rate (identifies the dependability of the service)

Difference between single and double slash in Xpath

Answer:
 /
  1.  start selection from the document node
  2. allows you to create 'absolute' path expressions
  3. e.g. “/html/body/p” matches all the paragraph elements
 //
  1.  start selection matching anywhere in the docume
  2. allows you to create 'relative' path expressions
  3. e.g. “//p” matches all the paragraph elements

Selenium Annotations

@Test
The annotation @Test identifies that a method is a test method.
Denotes a test method. Can be used with expected to assert expected results on the object under test.

@Before
Will execute the method before each test. This method can prepare the test environment (e.g. read input data, initialize the class).
Run before each test method is run i.e. do a setup

@After
Run after each test method is run i.e. do a teardown
Will execute the method after each test. This method can cleanup the test environment (e.g. delete temporary data, restore defaults).

@BeforeClass
Run before all the tests in a class (Runs once for all of the tests)
Will execute the method once, before the start of all tests. This can be used to perform time intensive activities, for example to connect to a database.

@AfterClass
Will execute the method once, after all tests have finished. This can be used to perform clean-up activities, for example to disconnect from a database.
Run after all the tests in a class (Runs once for all of the tests)

@Parameters
Allows you to run the same test with different data by defining the data parameters. @Parameters have to return List[], and the parameter will pass into class constructor as argument.

@RunWith

Exclusively tells the class that the Junit Test Case uses Parameterized runner
When a class is annotated with @RunWith or extends a class annotated with @RunWith, JUnit will invoke the class it references to run the tests in that class instead of the runner built into JUnit.

Why Cloud Testing

Traditional approaches to test a software incurs high cost to simulate user activity from different geographic locations.
Testing firewalls and load balancers involves expenditure on hardware, software and its maintenance. In case of applications where rate of increase in number of users is unpredictable or there is variation in deployment environment depending on client requirements, cloud testing is more effective.




Types of testing:
  • Stress Testing
  •  Load Testing 
  • Performance Test
  • Functional Test
  • Compatability Test
  • Browser 
  • Latency

 Steps for Cloud Testing
