Software Testing Tips:-
1 What's a 'test case'? Ans: A test case is a document that describes an input, action, or event and an expected response, to determine if a feature of an application is working correctly. A test case should contain particulars such as test case identifier, test case name, objective, test conditions/setup, input data requirements, steps, and expected results. Note that the process of developing test cases can help find problems in the requirements or design of an application, since it requires completely thinking through the operation of the application. For this reason, it's useful to prepare test cases early in the development cycle if possible. 2 What is the 'software life cycle'? Ans: The life cycle begins when an application is first conceived and ends when it is no longer in use. It includes aspects such as initial concept, requirements analysis, functional design, internal design, documentation planning, test planning, coding, document preparation, integration, testing, maintenance, updates, retesting, phase-out, and other aspects.
3 How is testing affected by object-oriented designs? Ans: Well-engineered object-oriented design can make it easier to trace from code to internal design to functional design to requirements. While there will be little affect on black box testing (where an understanding of the internal design of the application is unnecessary), white-box testing can be oriented to the application's objects. If the application was well-designed this can simplify test design.
4 What is verification? Validation? Ans: Verification typically involves reviews and meetings to evaluate documents, plans, code, requirements, and specifications. This can be done with checklists, issues lists, walkthroughs, and inspection meetings. Validation typically involves actual testing and takes place after verifications are completed.
5 What are the five common problems that occur during software development? Ans: Poor Communication – This is due to miscommunication for a developer as he don’t know what is needed by a customer. Or customers have unrealistic expectations. Poorly written requirements-This occurs when requirements are unclear, incomplete, not testable and too general. Schedules which are unrealistic-This occurs when too much of work is crammed in too little time. Inadequate testing –if none knows whether or not software is good until customers complain or system crashes. Adding new features after development is underway –This is a common practice to add new features after development is underway.
6 who is called a good test engineer? Ans: Good test engineer is one swho · Has a strong desire for quality, and "test to break" attitude. · who takes the point of view of the customer, · Has a strong desire for quality, Tactful and diplomatic · Has good oral and written communication skill. ·Has previous worked in software development .
7 What is the role of documentation in QA? Ans: In quality assurance Documentation plays a critical role, ALL the designs,Specifications ,code changes, test plans, business rules, inspection reports, configurations, test cases, bug reports, user manuals should be documented, all the practices should be documented, so that they are repeatable. Use documentation change management if possible, ideally there should be a system for easily finding and obtaining of documents and determining what document will have a particular piece of information.
8 What is a software project test plan? Ans: A software project test plan is a document that describes the objectives, scope, approach and focus of a software testing effort. The completed document will help people outside the test group understand the why and how of product validation. It should be thorough enough to be useful, but not so thorough that none outside the test group will be able to read it. The process of preparing a test plan is a useful way to think through the efforts needed to validate the acceptability of a software product.
9 What is a test case? Ans: A test case is a document that contains particulars such as Test case Name, objective, test case identifier, test conditions/setup, Input data requirements/steps and expected results.A test case describes an input, action, or event and its expected result, in order to determine if a feature of an application is working correctly, since it requires you to completely think through the operations of the application the process of developing test cases can help find problems in the requirements or design of an application. For this reason, if possible it is useful to prepare test cases early in the development cycle.
10 What is configuration management? Ans: Configuration management (CM) covers the tools and processes used to control, coordinate and track code, requirements, problems, designs, documentation, change requests, tools, patches, compilers, libraries, who makes the changes and changes made to them

Ajax Interview Tips:-
Hello Friends,I have brought a One more article for you.It is of a new type of programming where now are used in a web-based applications..
And The Use Of This article is ,in an Interview many HR asks a question what is Ajax?What are it's advantages and diasdvntages?
So read it an Have any problem contact Me...
Ajax, or AJAX (Asynchronous JavaScript and XML), is a group of interrelated web development techniques used to create interactive web applications or rich Internet applications. With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page. The use of Ajax has led to an increase in interactive animation on web pages. Data is retrieved using the XML Http Request object or through the use of Remote Scripting in browsers that do not support it. Despite the name, the use of JavaScript and XML is not actually required, nor do the requests need to be asynchronous.
Advantages OF Ajax
In many cases, related pages on a website consist of much content that is common between them. Using traditional methods, that content would have to be reloaded on every request. However, using Ajax, a web application can request only the content that needs to be updated, thus drastically reducing bandwidth usage and load time. The use of asynchronous requests allows the client's Web browser UI to be more interactive and to respond quickly to inputs, and sections of pages can also be reloaded individually. Users may perceive the application to be faster or more responsive, even if the application has not changed on the server side. The use of Ajax can reduce connections to the server, since scripts and style sheets only have to be requested once.
Disadvantages of Ajax.
Pages dynamically created using successive Ajax requests do not automatically register themselves with the browser's history engine, so clicking the browser's "back" button may not return the user to an earlier state of the Ajax-enabled page, but may instead return them to the last full page visited before it.
Workarounds include the use of invisible IFrames to trigger changes in the browser's history and changing the anchor portion of the URL (following a #) when AJAX is run and monitoring it for changes.
Dynamic web page updates also make it difficult for a user to bookmark a particular state of the application. Solutions to this problem exist, many of which use the URL fragment identifier (the portion of a URL after the '#') to keep track of, and allow users to return to, the application in a given state.
Because most web crawlers do not execute JavaScript code, web applications should provide an alternative means of accessing the content that would normally be retrieved with Ajax, to allow search engines to index it.
Any user whose browser does not support Ajax or JavaScript, or simply has JavaScript disabled, will not be able to use its functionality. Similarly, devices such as mobile phones, PDAs, and screen readers may not have support for JavaScript or the XMLHttp Request object. Also, screen readers that are able to use Ajax may still not be able to properly read the dynamically generated content.
The only way to let the user carry out functionality is to fall back to non-JavaScript. This can be achieved by making sure links and forms can be resolved properly and rely not solely on Ajax. In JavaScript, form submission could then be halted with "return false".
The same origin policy prevents Ajax from being used across domains, although the W3C has a draft that would enable this functionality.
The lack of a standards body behind Ajax means there is no widely adopted best practice to test Ajax applications. Testing tools for Ajax often do not understand Ajax event models, data models, and protocols. Opens up another attack vector for malicious code that web developers might not fully test for.

Preparation Of an Interview for Google :-
The Google Co,
They given us some very and useful basic tips for an Interview... So Thanks to them.Preparing for Google Interview:-
Google's interview process will vary by position but you can generally expect to have first-round interviews over the phone or on-campus and second-round interviews on-site at Google.
Interview Process
First-round interviews will either take place on your college campus or via phone. Both phone and in-person interviews are 30-45 minutes long and qualitative and open-ended in nature. The goal of the interview is to gain a better understanding of your problem-solving abilities, communication style, leadership skills and passion for Google.
Second-round interviews will generally take place on-site at Google. Second rounds usually take the full day and consist of two to four back-to-back interviews with our Googlers. If you happen to be in our office for interviews during meal times, the recruiter will accompany you to our cafeteria for a meal.
Who will you meet?
There are usually two contacts that will handle your candidacy throughout the interview process:
On-Campus interviews (University Programs): A member of the University Programs Team will meet you for your first-round interviews on-campus. They are not interviewing you, but setting up and facilitating your on–campus interview experience. They will also communicate with you about your status after the first-round interview.
Phone or On-Site interviews (Google Recruiter): If you applied for a position that is not holding on-campus interviews, you will have your first-round interviews via the phone. Your recruiter will set this up for you. For everyone (on–campus and phone interviewed candidates) that passes through to second-round interviews, a recruiter will become your main point of contact and handle your candidacy through to your final status.
Who will you interview with?: Both first and second-round interviews will be conducted by Googlers from the department that you applied to. For example, if you are interviewing for Finance, you will be interviewed by a member of the Finance department.
Interview Content and Preparation:
Your Background: Your interviewer may ask you a little bit about your work and academic background. Please prepare yourself for these questions beforehand.
Problem Solving: We're interested in learning more about how you solve problems. These questions will require you to walk us through a complicated scenario and discuss how you concluded your answer. Don't worry about being right or wrong--just answer to the best of your ability.
How to answer: Please be yourself. Here at Google, we believe in bringing your whole self to work and making the best possible match for you and for Google. We encourage you to be candid and active in your interview and to answer your questions clearly and concisely. If you need to take a moment and think through your answers, please do. It will help you and your interviewer understand your thoughts more clearly.
What to wear: At Google, you can be serious without a suit. While we have no formal dress code, you should look presentable during the day of your interview. Business casual is fine.
What to bring: Please bring an extra copy of your resume/CV and your provisional undergraduate/ graduate transcripts.
