Regression testing. The reason for depression.

The main motto of a reliable developer sounds like this: “Do no harm!” 

When he works with a code, regression testing is used for checking whether the general functionality of a product has been saved. This type of testing aims to search for vulnerabilities in an application or a program that has been already tested, and guarantees sustainability and compatibility of the system after bugs repairing. In fact, the main task of regression testing in the software testing is to solve unintentional problems caused by changes in a certain code fragment.

The next rule is: “Improving of the system functionality requires regression testing”. This condition should be fulfilled before the product is released. However, the full test cycle is not mandatory for all the products. But if yours is dynamic and requires upgrades constantly, you will undoubtedly need to carry out unit testing, integration testing and regression testing prior to launching user testing.

Usually, automatic testing is preferred in the most cases. Yet, if we speak about small projects, automation will only delay the release date. Thus, conducting manual regression testing would be the most cost-effective decision.

By trusting 4testers company to provide testing services for your business, you will save a lot of money. With the help of research and tools we apply, you will also save time in favour of the fastest release of the product to the target market.

Let’s find out what the regression testing process involves.

The process of regression testing

The first question that a tester asks himself when conducting this type of testing is “Which fragments have been damaged because of modification?” And no matter what methodology you use, regression testing is performed in several steps. To answer the question, you need to pass the following stages:

Gathering the information about the product, its previous modifications and corrections;

Determination of the general strategy and selection of regression testing tools;

Regression planning;

Test execution;

Regression analysis;

Founding a library of regression tests to avoid duplicate tests.

This routine can overload regular testers, and they will not have time for more extensive tasks. 




Imagine that you have a tight schedule — you need to launch a new version of the product, and your tester is engaged in regression testing that will take several days. After that, he will fix the bugs, which will take another day or two. How do you like such improvement, Steve Jobs?

When internal resources are exhausted and automation is fraught with delaying deadlines, crowdsourcing comes to the rescue. It is capable of speeding up the processes and taking the load off the core team of testers. 

Remote testers will do all the manual work, thereby providing free hands of your QA team. This speeds up the testing process without sacrificing product quality. That is why crowd testing agencies are so popular. Crowdtesting is a very profitable method for website and application testing.

Full regression testing

This type of research is applied at the final stage of product development or just before its release. It is necessary carried out:

For this purpose, test sets are searched for and the best one is defined to discover bugs during the whole testing. 

It is a long and labor-intensive process, but it is considered as the most effective technique. About 30% of the company budget is spent on testing. According to our research, more than half of expenses are directed on regression testing.  Converse the data into real money and you’ll realize it’s worth it.
