Regression Testing
The Regression Testing is done to uncover new software bugs, in existing functional and non-functional areas of a system after changes, such as enhancements, patches or configuration changes have been made to them. Regression Testing is mainly done to determine that change in one part of software lead to affect the other part of the software or not. It is also done to test the check the system efficiency. It is an integral part of the extreme programming software development method.

The set of assumptions, concepts and tools that provide support for automated software testing. The main advantage of these is that it provides low cost maintenance. Choosing the right frame work is very much essential for lowering the cost. Generally used frameworks are following:
* Linear
* Structure
* Data driven
* Key word driven
* Hybrid

Performance Testing
In order to evaluate the performance of the software in terms of responsiveness and stability, Performance Testing is done. Performance Testing also investigate and verify the others quality attributes of the system. There are various types of the Performance testing ie Load testing, Endurance, Spike, Configuration, Isolation and Stress Testing. It has following attributes:
* It judge on the performance criteria.
* It compares between the 2 and tells which is better.
* It also tells us which part is responsible for the bad performance of the system.
* It can be performed across the web and even in different parts of the country.

Security Testing Services
How Security testing does take a different mindset than functional QA testing?
"Security testing takes a different mindset than functional QA testing.

In the case of Input Validation a functional QA engineer can use worst scenarios to verify the functionality of component or features but on the other end a security engineer goes deeper and the thinking of this engineer would be like a malicious user as he must think how to break and abuse the application. Security testing is the type of testing which is used to identify risks in the system beyond the functional testing. A software security tester is free to focus directly on areas of code in which on attack is likely to succeed but functional QA testers are not able to do so.

Security Testing
Are testers as good as hackers in finding security holes in companies, web based applications. If not then why companies hire security testing professionals instead of hackers?
There is a fine line of difference between Security testing professionals and Hackers. Security testing professionals are hired by companies so as to protect the company's network from outside threats. They keep a tight vigil on all activities that can lead to disaster and misfortune for a company. They are like a firewall to the company's confidential data. Hackers on the other hand are elements that are responsible for cyber crime and various other illegal activities. Security testing professionals are core professionals and are a backbone to the company.

Software Testing Methodologies
What are the myths of software testing?

1. Tester's only job is to find bugs: Unlike developers, who are responsible for a specific function or component, the tester understands how the system works as a whole to accomplish customer goals.
2. Testing is very easy: At times testing can be a real challenging task. Tester should develop the capability to look or think beyond the requirements mentioned in the test plan or specifications. A tester has to apply all possible scenarios' to test the application.

Automation Testing Services

Have you ever done check automation using open-source tools? How did you identify the checks and what value did you add by automating them? Explain.

Commercial and open source tools have their own benefits. Commercial tools are easy to use and learn but have cost associated with them and also we cannot customized them, on the other hand open source tools can be used without any cost and can be customized according to project requirements but they also have their own limitations.
Checkpoints in software testing terms play a very important role whether you are doing functional testing or automation testing. Putting checkpoints in scripts means verifying and validating and comparing the existing functionality of an application with the actual one. The number of checkpoints shows the depth and the worth of the test automation script. Without checkpoints there will be no use of test automaton. When it comes to choosing the checkpoints a test automation engineer should always keep in mind the various changes in state of the application after a particular scenario or test steps.

Have you ever done check automation using open-source tools? How did you identify the checks and what value did you add by automating them? Explain.

Some of us performed automation testing through Open Source tool. Identifying the check in Open Source tool depend on the nature of automation tool. There are many checks which are restricted based on the application. In other words, on which application tester is using open source automation tool. Some open source automation tool's features get inactive for some application, although the same feature functions well in other application.

Do you think that Exploratory Testing is more than Superficial Bug Hunting? Explain why?

As both the techniques i.e. Exploratory Testing & Superficial Bug Hunting are used in finding the escape defects that are not covered in test case scenarios but in my views Superficial Bug Hunting is more helpful in finding those such errors. ET will be done by those testing team who have already tested the application and executed the test cases but in bug hunt we use the testers who haven't worked on that application. These testers would think from different prospective as compare to the team having a prior knowledge. Secondly ET will be done when all the SBT & RBT test cases have been executed and Bug hunt will perform just prior to the production release. So keeping the above points in mind we can say that Superficial Bug Hunting is more beneficial than ET.

Have you ever done check automation using open-source tools? How did you identify the checks and what value did you add by automating them? Explain.

In the testing industry, automation using open source tools has significantly gained momentum. We also got opportunity to automate several features/tasks using Selenium, Tellurium, and FitNesse. The silver line for automating any product is to go through all the test cases/requirements of the application and list down the areas which could be automated. Now, one of the most vital portions is to figure out which checks are a fit for the area, requirement, feature or story to be automated. The identification of checks would mainly depend on the understanding of the product (may be domain knowledge), requirement under test and the input/out parameters. Checks basically belong to region/portions which do not change frequently and requires very less intervention. So, automating them would save human effort, cost and provide more accuracy/precision by avoiding human dependency for a repetitive task.

Software Quality Testing
Planning, define and execution of test is very easily done by us, but what about Ad Hoc testing? Is it effective?
Ad-hoc testing is type of testing which being done without proper procedure and planning. Ad-hoc testing is not properly organized and structured. It is performed extemporize and based on the intuition and experience of the tester. The main motive of this testing is intended for finding the bugs which are not being encountered in a regular or structured flow .Ad-hoc testing is generally performed when tester has less time to do proper testing. Missing scenarios and flaws in test strategy can be caught or uncovered by performing ad-hoc testing. The issues which might be missed in regular testing cycles can be discovered in ad-hoc testing. Ad-hoc testing can be effective in increase the code coverage.
The major benefits of ad-hoc testing are mentioned below
1: No document, test plan and test cases are required.
2: Escaped bugs can be finding and help us in correcting our test strategy.
3: Easy going and less formal.
4: Required less time and efforts in completion
5: Help in covering the completeness of the testing.

Mobile testing
It is a process to assure the quality of mobile devices, like I phones, mobile phones, PDAs, etc. This testing will be conducted on hardware as well as software. And from the view of different procedures, the testing comprises of various testing as R&D testing, factory testing and certificate testing.
Mobile testing involves a set of activities from monitoring and troubleshooting various mobile applications, content and services on real handsets. It includes verification and validation of hardware devices as well as software applications.
Developing applications is a complicated business especially for the Android platform. You have to test with multiple operating system versions, hardware vendor interface layers, hardware configurations, and network capabilities. The testing matrix for Android-based applications can be a serious challenge, impacting your product's quality, time-to-market, and in the end, profitability.

Manual Testing
Manual testing is the process of manually testing software for defects or bugs. This requires a tester to play the role of an end user, and use most of all features of the application. To ensure completeness of testing, the tester often follows a written test plan that leads them through a set of important test cases. It is a type of software testing where Testers manually execute all the test cases without using any automation tools. Manual testing is the most of primitive of all testing types and helps find bugs in the software system.

Automation Testing
Automation Testing is the best way to increase the efficiency, effectiveness and coverage of the software testing. Generally we uses an automated software testing tool which is able to playback predefined actions and pre-recorded , compare the results and report the success or failure of these manual tests to the test engineer. Automated software testing reduces the time to run repetitive tests from days to hours. This time savings translates directly into cost savings. This can simulate tens, hundreds or thousands of virtual users interacting with networks or web software and applications.
