The WordPress.com stats helper monkeys prepared a 2014 annual report for this blog.
Here’s an excerpt:
A New York City subway train holds 1,200 people. This blog was viewed about 4,000 times in 2014. If it were a NYC subway train, it would take about 3 trips to carry that many people.
This is most frequent question asked to me ‘Why I’m a ‘Tester’ ?”.
As usual I want to be a good, Ninja Developer and the obvious answer for the question “where I want to see myself after couple of years in IT industry was never to see my self as a Tester”.
But, Unfortunately I was forced to be a tester with the provided reason was I wasn’t able to do code. I didn’t get good sleep for so many months 😦
I was struggling to quit my first job and want to get back to development, so I never loose my hands on doing code and exploring the technologies.
Meanwhile my offshore client “Completely Nontechnical” manager was looking for “value for money”, she want her team should be most innovative among all others. She was the first person who was believing in my abilities and the journey begins here.
The fruitful outcome of my hard efforts, put me on top. I was leading by the technology not by the position.
Suddenly, I observed that it’s really easy to achive a leading position in QA field and that’s change my way to look testing as a carrier.
Step 1:- As always, you have setup android-sdk and Eclipse.
Step 2:- Please add this jars in Eclipse libs folder
Step 3:- You will need to know your app’s Bundle ID (the same as a package in Java project). It could be found using Xcode. Bundle ID (package com.blabla.company) is simply specified under an app’s name in Xcode. Install app into iOS device. Mount iOS device to your computer using USB. Then launch Xcode. In Xcode panel’s left menu (Windows-> Organizer), choose your iOS device, then click on “Applications” menu under it. There your application will be listed. Bundle name is under the title of your app.
Step 4:- will need to know your device’s UDID. Important to know that serial number is not the UDID. To find your iOS device’s UDID, please follow this simple guide: www.whatsmyudid.com
So, here is simple code to launch and run your JUNIT script.
Start your Appium server and run this code from eclipse.
package test.java.com.appium;
public class AppiumIOSTest {
private AppiumDriver driver;
@Before
public void setUp() throws Exception {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName", "ios");
capabilities.setCapability("deviceName","iOS");
capabilities.setCapability("udid", “<<<your iOS device UDID>>>”);
capabilities.setCapability("app", “<<<your app’s bundle id>>>”);
driver = new RemoteWebDriver( new URL( "http://127.0.0.1:4723/wd/hub" ), capabilities );
}
@After
public void tearDown() throws Exception {
driver.quit();
}
@Test
public void testScriptGoesHere() throws Exception {
System.out.println("Test Output From Within the test");
System.out.println("Here goes your test script");
}
} I hope you have setup android-sdk and Eclipse.
Please add this jars in Eclipse libs folder
How, to interact with web elements for your iOS/Android Device use device-mode inbuilt Chrome 32+ feature
So, here is simple code to launch and run your JUNIT script.
Start your Appium server and run this code from eclipse.
public class Browser {
private AppiumDriver driver;
// private RemoteWebDriver driver;
@Before
public void setUp() throws Exception {
// set up appium
DesiredCapabilities capabilities = DesiredCapabilities.android();
capabilities.setCapability("deviceName", "galaxy S4");
capabilities.setCapability("platformName", "Android");
capabilities.setCapability(CapabilityType.VERSION, "4.4.2");
capabilities.setCapability(CapabilityType.BROWSER_NAME, "chrome");
capabilities.setCapability("androidPackage", "com.android.chrome");
driver = new AppiumDriver(new URL("http://127.0.0.1:4723/wd/hub"),
capabilities);
}
@Test
public void openBrowsers(){
driver.get("http://google.com");
WebElement searchBox = driver.findElement(By.name("q"));
searchBox.sendKeys("hello Appium");
driver.findElement(By.name("btnG")).click();
}
@After
public void tearDown() throws Exception {
driver.quit();
} }

* How to setup and run Gatling on Mac :-
Most of the time devices are not get detected by Android Debug Bridge(ADB) on Windows devices.
1. Please set %ANDROID_HOME%\tools and %ANDROID_HOME%\platform-tools environment variable.
2. Open command prompt and type command
adb deices
0486c1332523fae6 devices. It means your device is detected
But if your devices not shown(not detected) in list on command prompt, here are few software which helps you to sort out devices are not detected.
Also We need more stuff to detect Google Devices on windows.
Android commands for every day !
android sdk :- To launch android SDK manager.
android avd :- To launch android Virtual Device Manager.
emulator @AVDName :– To launch your emulator
adb install path/to/your/app.apk :- To install android app on mobile through command line
adb -s emulator-5554 install path/to/your/app.apk :- To install android app on emulator through command line
adb shell screenrecord /sdcard/demo.mp4 :- To record screen session
adb shell settings get secure android_id :- to get Secure Android ID :- which is unique id created for every android device for first time use and can be changed on factory reset.
uiautomatorviewer :- To launch Android App debugger.
adb shell pm get-install-location :- To check app installation is on internal memory or it on SD Card.
Here is the good document regarding Appium Architecture, which is very useful to read before starting actual coding. 🙂
Important Documentation :-
Here are the steps to run rspec ruby script for android automation for android API level >17 i.e using uiautomator:-
(Note :- uiautomator is android’s default ui test runner available on API level <17)
Make sure you have latest version of java installed and JAVA_HOME environment variable SET.
Download and install Android SDK (use USE AN EXISTING IDE option to just download SDKs). After installation open Android SDK Manager and install all API levels.
Set System Variable Android_HOME to C:\Users\abc\android-sdks and accordingly for MAC and Linux.
Set Path variable to %Android_HOME%\platform_tools, %Android_HOME%\tools
Open Terminal or Command-prompt. Run adb if it is successful identified your command means your ANDROID_HOME set properly otherwise check it again.
Follow the step to create new AVD(Android Vertual Devices) here or use external android devices to run automation.
Download Appium Setup Extract zip file to windows user folder rename folder as a Appium. for MAC/Linux install .dmg package.
Download and install node.js server.
Try to run Appium(if your .Net framework is outdated it will ask you to install updated version. Please do install latest .Net Framework)
Following command will launch emulator or use external devices.
emulator @NameofEmulator
Following command will show all attached devices list with device id
adb devices
Launch Appium by double clicking on the Appium icon in Appium folder that you extracted in your user folder for Windows. for MAC appium& will launch the node.js server.
Here are the steps to run rspec ruby script for android automation for android API level <17:-
(Note :- uiautomator is android’s default ui test runner available on API level <17) so we are using selendroid server
Clone appium github code (Don’t download zip file which leads problems in git url not found when rebuilding selendroid.)
git clone https://github.com/appium/appium
Go to C:\Windows\Temp folder and delete selendroid.com.examlepackage.mobility.apk file also com.examlepackage.mobility folder
we may need to rebuild selendroid server by cd to appium-master github code directory and run command
reset.bat –selendroid
To run automation on lower android devices we need to use ‘Selendroid’ as shown below( Appium Bug is still open)
capabilities = {
‘browserName’ => ‘Selendroid’,
‘platform’ => ‘WINDOW’,#Mac, Linux
‘version’ => ‘2.3.3’,
‘device’ => ‘Selendroid’,
‘app’ => absulute_path,
‘app-package’ => ‘com.example.android.contactmanager’,
‘app-activity’ => ‘com.example.android.contactmanager.ContactManager’
}
Node server will be launched.
install necessary ruby gems
gem install selenium-webdriver
gem install rspec
gem install net-http-persistent
Run your rspec ruby script given Here.
Ruby script :- (Run rspec your_file_name.rb)
require ‘selenium-webdriver’
require ‘selenium/webdriver/remote/http/persistent’
require ‘rspec’
absulute_path = ‘C:\Users\abc\Desktop\AppiumTest\ContactManager.apk’
capabilities = {
‘browserName’ => ‘Android’,
‘platform’ => ‘WINDOW’,#Mac, Linux
‘version’ => ‘4.3’,
‘device’ => ‘Android’,
‘app’ => absulute_path,
‘app-package’ => ‘com.example.android.contactmanager’,
‘app-activity’ => ‘com.example.android.contactmanager.ContactManager’
}
server_url = ‘http://127.0.0.1:4723/wd/hub’
describe “Contact” do
before :all do
@driver ||= Selenium::WebDriver.for( :remote,
:desired_capabilities => capabilities, :url => server_url,
)
end
after :all do
@driver.quit if @driver
end
it “add a contact” do
new_button = @driver.find_element(:name, “Add Contact”)
new_button.click
wait = Selenium::WebDriver::Wait.new(:timeout => 20) # seconds
textfields = @driver.find_elements(:tag_name,”textfield”)
textfields[0].send_keys(“Android_Appium”)
textfields[1].send_keys(“12345”)
textfields[2].send_keys(“Android@Appium.com”)
@driver.find_element(:name, “Save”).click()
end
end
Explanation of ruby script :-
*Capabilities*
capabilities = {
‘browserName’ => ‘Android’,
‘platform’ => ‘WINDOW’,#Mac, Linux
‘version’ => ‘2.3.3’,# 4.3
‘device’ => ‘Selendroid’,#Android
‘app’ => absulute_path,
‘app-package’ => ‘com.example.android.contactmanager’,
‘app-activity’ => ‘com.example.android.contactmanager.ContactManager’
}
Instantiate Selenium driver instance with server_url as node.js server uses JSON-Wire Protocol.
Appium will execute JsonWireProtocol command by converting selenium code.
server_url = ‘http://127.0.0.1:4723/wd/hub’
@driver = Selenium::WebDriver.for(:remote, :desired_capabilities => capabilities, :url => server_url)
@driver instance will launch your application specified in capabilities on emulator or on attached devices.
I’m able to run ruby scripts for android devices on Win 7(64 bit) machine with android Devices having API level >15(version 4.1+) as uiautomator is only supported by android devices having API level >15(version 4.1+) with capabilities
capabilities = {
‘browserName’ => ‘Android’,
‘platform’ => ‘WINDOW’,#Mac, Linux
‘version’ => ‘4.3’,
‘device’ => ‘Android’,
‘app’ => absulute_path,
‘app-package’ => ‘com.example.android.contactmanager’,
‘app-activity’ => ‘com.example.android.contactmanager.ContactManager’
}

Search engine optimization (SEO) : SEO works in two ways
Search engine optimization (SEO) is the process of affecting the visibility of a website or a web page in a search engine’s “natural” or un-paid (“organic”) search results. In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine’s users .
Here We discuss about optimizing search engines for “natural” or un-paid (“organic”) search results.
Example:
Consider, you are a librarian and many people depend on you to find exact book you need. You need to know , what inside every in every book and how they related to each other.
So you need to store a lot of information and it should be properly structured.
How Search Engines works:
As we discussed search engines stores a lot of information using Search engine indexing. Search engine indexing is a database where information(after being collected, parsed, and processed) is stored to allow quick retrieval. Cache base search engines stores index along with Carpus(collection of documents). Search engine indexes are auto updating for new feeds and stores collection of data by auto merging.
factors which affects your web content search visibility:-
Google PageRank Algorithm:-
| Toolbar PageRank (log base 10) | Real PageRank |
| 0 | 0 – 10 |
| 1 | 10 – 100 |
| 2 | 100 – 1,000 |
| 3 | 1,000 – 10,000 |
| 4 | 10,000 – 100,000 |
| 5 | and so on… |
i.e. the PageRank value for a page u is dependent on the PageRank values for each page v contained in the set Bu (the set containing all pages linking to page u), divided by the number L(v) of links from page v.
PR(A) = (1 – d) + d(PR(B)/1) and PR(B) = (1 – d) + d(PR(A)/1) We get,
PR(A) = 0.15 + 0.85 * 1 = 1 and PR(B) = 0.15 + 0.85 * 1 = 1
PR(A) = (1 – d) + d(PR(B)/1) and PR(B) = (1 – d) + d(PR(A)/1) We get,
PR(A)= 0.15 + 0.85 * 40 = 34.25 ,
PR(B) = 0.15 + 0.85 * 0.385875 = 9.1775
PR(A)= 0.15 + 0.85 * 29.1775 = 24.950875
PR(B) = 0.15 + 0.85 * 24.950875 = 21.35824375 and so on …
Please note some observations here:-
Page 1:- donates = 1/3+1/3+1/3 = 1 and gains 1+1/2 = 1.5 importance.
Page 2:- donates = 1/3+1/2 = 0.83 and gains 1/3 = 0.33 importance.
Page 3 :- donates = 1 = 1 and gains 1/3 +1/2+1/2 = 1.33 importance.
Page 4 :- donates = 1/3+1/2 = 0.83 and gains 1/2 = 0.5 importance.
then, Matrix will be, A :-
Linear system of equations =
We, got a linear equation:-
PR(x) = 0.38 + 0.132 +0.29 + 0.19 = 0.992
(Since PR never cross 1 and average/Maximum PR will be 1)
Linking your web content with many links can increase your search visibility and A outbound link from highly Ranked page optimize your search query.
Most of the mainstream languages, including object-oriented programming (OOP) languages such as C#, Visual Basic, C++, and Java, were designed to primarily support imperative (procedural) programming.
And Haskell, gofer like languages are pure functional, Here we elaborate what is the difference between this two way of programming?
functional languages: The functional programming paradigm was explicitly created to support a pure functional approach to problem solving. Functional programming is a form of declarative programming.
Imperative languages: An imperative language uses a sequence of statements to determine how to reach a certain goal. These statements are said to change the state of the program as each one is executed in turn.
Pros:
Cons:
It’s depend on user requirement to choose the way of programming, so there is harm only when user don’t’ choose the proper way.
When evolution goes the wrong way, you have problems:
Where n Why ?
… and so on and on …
… and so on and on …
Examples: Java is an imperative language. For example, a program can be created to add a series of numbers:
int total = 0;
int number1 = 5;
int number2 = 10;
int number3 = 15;
total = number1 + number2 + number3;
Each statement changes the state of the program, from assigning values to each variable to the final addition of those values. Using a sequence of five statements the program is explicitly told how to add the numbers 5, 10 and 15 together.
Summary:
In imperative languages you tell the computer how to change bits, bytes and words in it’s memory and in what order. In functional ones, we tell the computer what things, actions etc. are. For example, we say that the factorial of 0 is 1, and the factorial of every other natural number is the product of that number and the factorial of its predecessor. We don’t say: To compute the factorial of n, reserve a memory region and store 1 there, then multiply the number in that memory region with the numbers 2 to n and store the result at the same place, and at the end, the memory region will contain the factorial.
