File Engine

DEXTER'S LAB

Hi folks,
              After a long time, i have come across a great product. Which is really a wish come true for small office network who are having a vision of making it big. This is more to say likely to be called as a competitor to bigger server giants but i would say or call it a SEVERE THREAT to those money makers. I started getting more information when i got a over view about this product. This is even got a remarkable name called File Engine, the server is affordable to all (by which i mean all, even if you have small office with 2 computers who needs a backup server). This is not like CLOUD where you dont know where your server is but FILE ENGINE would provide you the machine and even there is disaster of data lose they assure you that they will be there to get them back for you. Yes, ofcourse they do it and they have 100's of customers who are already using this product and are happy.... If you want to know about this product, click here FILE ENGINE
or just google it File Engine or filesafe server...

I personally think this is going to be trend setter...

Iphone 4

Physical size
The iPhone 4 is 4.5 x 2.31 inches, and 0.37 inch and weighs 4.8 ounces (137 grams).

The brain has an Apple A4 chip inside, just like the iPad. The A4 has few interconnected chips: A Cortex-A8 main processor unit—the main brain—paired with PowerVR SGX 535, handles the high definition graphics of the new iPhone. They are directly connected to each other and two low-power 128MB DDR SDRAM chips. As these components are in the same chip, Apple claims the iPhone 4 can process data more quickly by consuming less battery than ever.

The A4 consumes less power because its sub-components can be switched on and off when they are not needed, saving watts whenever possible.

Battery life
The battery life is 16% bigger now. Fused with the A4 processor and new display, it helps in a longer battery life: Apple says now 40% more talk time.

• Talk over 3G: 7 hours.
• Browsing over 3G: 6 hours.
• Browsing over Wi-Fi: 10 hours.
• Video: 10 hours.
• Music: 40 hours.
• Stand-by: 300 hours.

The display
The 3.5-inch multitouch screen has resolution of 960 × 640 pixels. Apple calls it as Retina Display, and 4 times as many pixels as the current iPhone 3GS' display. The screen has 326 ppi resolution, a higher definition than a magazine.

iPhone 4: The Definitive Guide

Apple says, that this IPS-based display is same technology as used in the iPad—also(800-to-1) contrast ratio which is 4 times better than the 3GS, with a higher viewing angle.

The apps have automatic advantage of the increased relative resolution, That means they will be a lot sharper for text, 3D graphics and vectorial art. However, developers have to include higher resolution bmp images to get the app look perfect.

Similar to iPhone 3GS and the iPad, the display has an oleophobic layer which makes it easier to clean.

The main camera
New iPhone has bigger sensor for the main camera. It has backlit and bigger lenses too. Instead of having a higher resolution, the sensor maintains the same 5 megapixel count. They are bigger dots,so it has a higher ISO—or sensitivity to light. Which means that you would be able to take better photos and video in low light conditions and the pics will look a lot better.

iPhone 4: The Definitive Guide

The camera has a LED flash light, that works both for photographs and video. To focus, both photos and videos, you just need to tap on the screen.

WOW, video conferencing camera at front, there's a video conference camera, with a standard VGA resolution. It can be used with third-party applications, as well as Apple's video conference solution.

Gyroscope
 iPhone 4 has a gyroscope built-in. Which means that it can track movement with a very high precision, much higher than accelerometers in previous iPhones. It has 3-axis, so it is capable of detecting pitch, roll, and yaw. Coupled with accelerometer, it has 6-axis motion sensing.

Sony announces death of the floppy disk..Thats sad...

London, April 27 (ANI): Sony is finally killing off the floppy disk.

The Japanese electronics manufacturer, that sold over 12 million of the devices, has made it clear that it will stop making floppy disks from next year, leaving no manufacturer in the market, reports The Telegraph.

"It's amazing to think anyone still uses them, but they are popular still in Japan and India. The last time I used one was when I was at school," said Kat Hannaford, the technology websites Gizmodo' contributing editor.

"Due to dwindling demand, Sony discontinued European production of 3.5 inch floppy disks in September 2009. The last European sale of a floppy disk took place in March 2010," said a spokesman for Sony in Britain.

First developed in 1971, floppies have helped consumers store documents, pictures and data on an easy to use format.

Delhi Police to get mini robot to tackle terror threat

New Delhi, May 6 (IANS) Ahead of the Commonwealth Games, the Delhi Police is set to buy a mini remote-operating vehicle (MROV) that can detect and defuse bombs and explosives, an official said Thursday.

Delhi Police spokesperson Rajan Bhagat said: 'We had a technical evaluation of the MROV (Wednesday). This is the first step in the procurement process.

'Bidding for the price is yet to be done. We are hoping to get it before the Commonwealth Games,' he added.

Manufactured in Canada, the primary function of the MROV is to detect and disarm hidden bombs and explosives. The robot, which weighs 65 kg, can be controlled by a remote within a radius of 500 metres. It can drag weights of up to 113 kg.

The MROV has arms and shoulders and also four night-vision cameras. It is weather-proof but not fire resistant.

It can operate underwater and over rough terrain, moving at a maximum speed of 8 kmph and a minimum of speed of 3 kmph.

Joint Commissioner (north) Karnal Singh said: 'Although the device is designed in Canada, it is suitable in the Indian scenario, particularly in the national capital where it will be able to help in bomb scare situations.'

QTP Q & A

1. What is Quick test pro?
It’s a Mercury interactive’s keyword driven testing tool

2. By using QTP what kind of applications we can test?
By using QTP we can test standard windows applications, Web objects, ActiveX controls, and Visual basic applications.

3. What is called as test?
Test is a collection of steps organized into one or more actions, which are used to verify that your application performs as expected

4. What is the meaning of business component?
It’s a collection of steps representing a single task in your application. Business components are combined into specific scenario to build business process tests in Mercury Quality center with Business process testing

5. How the test will be created in QTP?
As we navigate through our application, QTP records each step we perform and generates a test or component that graphically displays theses steps in a table-based keyword view.

6. What are all the main tasks which will be accomplished by the QTP after creating a test?
After we have finished recording, we can instruct QTP to check the properties of specific objects in our application by means of enhancement features available in QTP. When we perform a run session, QTP performs each step in our test or component. After the run session ends, we can view a report detailing which steps were performed, and which one succeeded or failed.

7. What is Actions?
A test is composed of actions. The steps we add to a test are included with in the test’s actions. By each test begin with a single action. We can divide our test into multiple actions to organize our test.

8. What are all the main stages will involve in QTP while testing?
    * Creating tests or business components
    * Running tests or business components
    * Analyzing results

9. How the creation of test will be accomplished in QTP?
     We can create the test or component by either recording a session on our application or web site or building an object repository and adding steps manually to the keyword view using keyword-driven functionality. We can then modify our test with programming statements.

10. What is the purpose of documentation in key word view?
     The documentation column of the key word view used to displays a description of each step in easy to understand sentences.

11. Keyword view in QTP is also termed as
Icon based view

12. What is the use of data table in QTP?
Parameterizing the test

13. What is the use of working with actions?
To design a modular and efficient tests

14. What is the file extension of the code file and object repository file in QTP?
The extension for code file is .vbs and the extension for object repository is .tsr

15. What are the properties we can use for identifying a browser and page when using descriptive programming?
The name property is used to identify the browser and the title property is used to identify the page

16. What are the different scripting languages we can use when working with QTP?
VB script

17. Give the example where we can use a COM interface in our QTP project?
COM interface appears in the scenario of front end and back end.

18. Explain the keyword create object with example
Create object is used to create and return a reference to an automation object.

For example:

Dim ExcelSheetSet

ExcelSheet=createobject(“Excel.Sheet”)

19. How to open excel sheet using QTP script?
You can open excel in QTP by using the following command

System.Util.Run”Path of the file”

20. Is it necessary to learn VB script to work with QTP?
Its not mandate that one should mastered in VB script to work with QTP. It is mostly user friendly and for good results we need to have basic VB or concepts which will suffice

21. If Win Runner and QTP both are functional testing tools from the same company. Why a separate tool QTP came in to picture?

QTP has some additional functionality which is not present in Win Runner. For example, you can test (Functionality and Regression testing) an application developed in .Net technology with QTP, which is not possible to test in Win Runner

22. Explain in brief about the QTP automation object model
The test object model is a large set of object types or classes that QTP uses to represent the objects in our application. Each test object has a list of properties that can uniquely identify objects of that class

23. What is a Run-Time data table?
The test results tree also includes the table-shaped icon that displays the run-time data table-a table that shows the values used to run a test containing data table parameters or the data table output values retrieved from a application under test

24. What are all the components of QTP test script?
QTP test script is a combination of VB script statements and statements that use QuickTest test objects, methods and properties

25. What is test object?
It’s an object that QTP uses to represent an object in our application. Each test object has one or more methods and properties that we can use to perform operations and retrieve values for that object. Each object also has a number of identification properties that can describe the object.

26. What are all the rules and guidelines want to be followed while working in expert view?
Case-sensitivity

VB script is not case sensitive and does not differentiate between upper case and lower case spelling of words.

Text strings

When we enter value as a string, that time we must add quotation marks before and after the string

Variables

We can use variables to store strings, integers, arrays and objects. Using variables helps to make our script more readable and flexible.

Parentheses

To achieve the desired result and to avoid the errors, it is important that we use parentheses() correctly in our statements.

Comments

We can add comments to our statements using apostrophe (‘), either at a beginning of the separate line or at the end of a statement

Spaces

We can add extra blank spaces to our script to improve clarity. These spaces are ignored by the VB script

bug-life-cycle

Wikipedia def of Bug is: “A computer bug is an error, flaw, mistake, failure, or fault in a computer program that prevents it from working correctly or produces an incorrect result. Bugs arise from mistakes and errors, made by people, or a program’s source code or its design.”

Other def can be:
An unwanted and unintended property of a program or piece of hardware, especially one that causes it to malfunction.or
A fault in a program, which causes the program to perform in an unintended or unanticipated manner.

The general definition of bug is: “failure to conform to specifications”.

If you want to detect and resolve the defect in early development stage, defect tracking and software development phases should start simultaneously.

We will discuss more on Writing effective bug report in another article. Let’s concentrate here on bug/defect life cycle..

Life cycle of Bug:

1) Log new defect
When tester logs new bug the mandatory fields are:
Build version, Submit On, Product, Module, Severity, Synopsis and Description to Reproduce

In above list you can add some optional fields if you are using manual Bug template:

These Optional Fields are: Customer name, Browser, Operating system, File Attachments or screenshots.

The following fields remain either filled or blank:
If you have authority to add bug Status, Priority and ‘Assigned to’ fields them you can specify these fields. Otherwise Test manager will set status, Bug priority and assign the bug to respective module owner.

 Bug life cycle:


The figure is quite complicated but when you consider the significant steps in bug life cycle you will get quick idea of bug life.

On successful logging the bug is reviewed by Development or Test manager. Test manager can set the bug status as Open, can Assign the bug to developer or bug may be deferred until next release.

When bug gets assigned to developer and can start working on it. Developer can set bug status as won’t fix, Couldn’t reproduce, Need more information or ‘Fixed’.

If the bug status set by developer is either ‘Need more info’ or Fixed then QA responds with specific action. If bug is fixed then QA verifies the bug and can set the bug status as verified closed or Reopen.

Bug status description:
These are various stages of bug life cycle. The status caption may vary depending on the bug tracking system you are using.

1) New: QA files new bug.

2) Deferred: If the bug is not related to current build or can not be fixed in this release or bug is not important to fix immediately then the project manager can set the bug status as deferred.

3) Assigned: ‘Assigned to’ field is set by project lead or manager and assigns bug to developer.

4) Resolved/Fixed: When developer makes necessary code changes and verifies the changes then he/she can make bug status as ‘Fixed’ and the bug is passed to testing team.

5) Could not reproduce: If developer is not able to reproduce the bug by the steps given in bug report by QA then developer can mark the bug as ‘CNR’. QA needs action to check if bug is reproduced and can assign to developer with detailed reproducing steps.

6) Need more information: If developer is not clear about the bug reproduce steps provided by QA to reproduce the bug, then he/she can mark it as “Need more information’. In this case QA needs to add detailed reproducing steps and assign bug back to dev for fix.

7) Reopen: If QA is not satisfy with the fix and if bug is still reproducible even after fix then QA can mark it as ‘Reopen’ so that developer can take appropriate action.

8 ) Closed: If bug is verified by the QA team and if the fix is ok and problem is solved then QA can mark bug as ‘Closed’.

9) Rejected/Invalid: Some times developer or team lead can mark the bug as Rejected or invalid if the system is working according to specifications and bug is just due to some misinterpretation.
