Quick Guide To Regression Testing

By
Regression testing
A Regression testing is the part of testing carried out to ensure that the changes made in fixes & any growth of changes are not impacting antecedently (previously) working functionality. It’s executed after augmentation and the defect fixes in software & its environment. It can be arduous to determine how much retesting is needed, specifically near the end of development cycle.
In another words, A Regression testing is the activity of testing changes to the computer’s program to make sure that previous programming still works with new changes.
Types of the Regression Testing
There are mainly two types of regression testing:
1.       Regular Regression Testing.
2.       Final Regression Testing.
Regular Regression Testing:
Regular Regression testing is complete between the test cycles & to ensure that the defects fixes that are done & functionality that were the working with earlier test cycle continue with the work.
Final Regression Testing:
Final regression testing is performing to validate the builds that has not changed for the period of time. This build is deployed and shipped to customers.
A quick guide helps you in a systemized regression testing:
a.       Allocates the time for testing. As the time is the first duress (constraints) for all software testers, they have to be proficient enough to provide for the sufficient coverage of all software’s fields in short time.
b.      Fix all the contributing factors. There are the cases when even with it is the defects fixed and the product does not operate as intended. This often caused by developer’s failures and to fix root the issues of defects and fixing just secondary ones. Therefore, it is very critical to find all the causative factors to fix them before the rest.
c.       Be mindful with fixed bugs. Seldom, when the developers fix the definite bugs, they may the cause of new ones that can go un-noticed. That is why, when executing regression tests, testers should be alert or vigilant.
d.      Points on the functional aspects. During the regression testing only those issues affecting application’s functionality should be taken into idea. Design the aspects that are equally vital, however in most of cases you should not spend the time on them.
e.      Builds you’re regression tests suite. Creating such the suites is helpful in order to exposes the bug’s when software is re-tested.


Methodologies of regression testing:
The test methodology for the regression testing:
1.       Understanding criteria to selects the test cases for Regression Testing.
2.       Prioritization of the test cases.
3.       Methodology for select the test cases.
4.       Re-setting test cases for the test run.
5.       Concluding the outcome of a regression test cycle
Benefits of regression testing:
1.       A Regression testing increases the chances of detecting the bugs caused through the changes to a software & application both enhancements and defect fixes.
2.       A Regression testing is also detects the un-desirable side caused always through the changing of the operating environments.

3.       Set about regression tests is too useful for a new path about doing the integration testing. This is the new mode is quite faster or little confusing than old path about doing the integration testing.

Steps To Hunt the Bugs Successfully

By
The testers should catch the bugs in software that they’re testing. Testers should try to catch as several vital bugs as soon as possible. Catching the crucial bug earlier on Product-Life-Cycle can save the Projects from financial losses & mitigate the risks as compared for catching the same at a later stage in SDLC. Steps to hunt the bugs: Sometimes it’s useful to break the rules: The following test cases, which were predefined a tester can miss the bugs so it makes it impossible’s to provide the product i.e. 100 percent bug free. If you-follow pre-determined test cases you risks becoming blind to outside the bugs. A first secret is to check the functionality under the test. It’ll be an effective channel to discover the more bugs, because functionality is not generally covered by the test cases. Examine the patterns: You might have noticed that the bugs can be often met in the groups, one can call them-gregarious. The testing a new but the similar functionality...

Cross browser testing Tools

By
Cross Browser testing It is a process to test the web apps across multiple browsers. It involves the checking compatibility of the app across multiple web browsers & ensures that your web app’s works correctly across different web browsers. Tools for Cross Browser Testing Browser shots: The browser shots might be most exhaustive cross browser-testing tool that exists. Browser Shots includes all of most popular-browsers, like Firefox, Chrome, & Safari, along with the tons of another browser’s that might sound unfamiliar, like Sea Monkey, Flock, & Iceape. You can adjust the resolution, color-settings, & even Flash and JavaScript settings. Cross Browser Testing: It allows users to test their websites with over the hundred resolution or browser and Operating System combinations. This also has support to mobile web-browsers, which is crucial because the web traffic is making shift from the primarily desktop computer users to primarily mobile ...

Mobile Application Testing: Strategy for Development

By
There are a huge number of demands and lots of competitions in the mobile application industries. In that demands and competitions, the mobile application testing has become more important. The testing phase of the mobile application testing looks like evil between the creative process and excitement of new products in the market. According to the survey, “In US, on an average 2-3 hours per day people spends their time on smartphones and tablets. On that time, they spent 80% on mobile application and remaining 20% on web applications.” Few list of key factors for successful mobile application testing strategies are: Selection of Device for Testing : Before introducing the mobile application test activities, first select the devices for testing the application. Selection decision is very important because only devices can help to targets maximum numbers of the customers for accessing the application. There are two parts for device selection: §   Device Model ...
