An Expert Guide On Regression Testing

A software regression is any undesired variation that occurs from code changes. Let just take an example of this is you take your vehicle to a mechanic shop to get the air conditioning repaired, and when you get it back, the air conditioning is repaired but now the gas tank sensor stops working. Bummer.

In software, a regression can occur after a new feature is completed. Let’s say an email photo sharing service introduces video adaptability, but after the ability is released, the primary function of sharing photos to a set group of email addresses is completely broken.

Given that a regression is an unintended change, then regression testing is the method of hunting for these changes.

Automated regression testing is a crucial part of improving software quality, and having an effective plan in place is a great idea to reduce software error throughout the software development process.

Best Practices/strategies for Regression Testing

·         Tightly link the regression testing with functional testing & build the regression tests out of successful test cases created & applied during the functional testing.

·         We require identifying the application areas identified to have the high rate of failures & include more regression tests in them.

·         Depending upon the risk factors across the business, we can design the regression test suite. It has been seen that there are specific kinds of failures, which are not expected, but whenever they occur, they leave the serious impact on the business process.

·         For smaller projects, do regression testing after every successful compile or at least once in a week.

Quality Assurance Approach and Best Practices

QA Approach :

Our strategy to QA is what truly sets us apart from an already compact development landscape and We'd like to discuss with you a comprehensive list of best practices that have proven successful time and time again:

Best Practices:

Focus on the User Experience

Assessing at all levels of the project is crucial, but the most significant matter to think about is the user experience. In the event the UX is poor, it necessarily means the quality isn't at par. Although this will likely result in changes during previous levels of growth, the consumer experience should always be in the forefront.

Automation and Continuous Integration

Automation is vital because it provides fast feedback, enabling constant integration -- a crucial part of the agile methodology. Automation is also key to reducing costs and enhancing the overall efficiency of your team; which is one of the main reasons why QA managers should educate themselves and be eager to execute automation practices.

Test Coverage and Code Coverage

Many QA engineers talk a lot about"test policy," that gives a fantastic general picture of the calibre of the application. But to achieve true quality, the two test cases and code coverage analysis must be considered. 

For instance, even in the event that you reach 100% test coverage, then you have to still target for at least 90% function code policy to guarantee the best outcomes.

The Shift-Left Approach

Typically, testing starts once the coding phase is complete. However, for optimal quality within an agile methodology, you have to shift the focus and start monitoring and testing right from the beginning of the project. 

This guarantees that bugs are detected earlier, which not just saves time and money but also can help ensure a good relationship with developers on the team, accelerates the delivery of this item, and allows for increased test coverage.

Smart Testing

Complete and comprehensive testing can occasionally pose a challenge because many teams might not have adequate time or funds to experience every possible combination of instances. However, you should be smart in how and what you examine. This means, communication with the developer to find small test cases which will uncover the greatest number of bugs.

Bug Prevention

QA engineers are trained to catch bugs, but a resourceful QA engineer may also consider how to prevent them in the first location. Traditional QA testing begins at the UI level, but an agile approach starts with functional and unit testing and then moves into the UI level. 

This strategy prevents bugs from entering greater levels of growth which can cause larger problems in the future and probably delay delivery.

Quality Over Quantity

Concentrate on important critical bugs and glitches initially instead of several smaller ones.
