The software has got very wide-spread in the modern society life. Nevertheless, about 90% of products that are produced have disadvantages. The main stages of software testing that must be performed before transferring the product to another level are: basic functionality testing, code review, static code analysis, unit testing, early stage of development, product testing before launch.

Basic Functionality Testing

Functional testing is a type of software that checks the software system for compliance with functional requirements. It is performed by evaluating all the system’s functionality. The verification process starts with the help of output appropriately. Choosing an appropriate method is a crucial part as it allows us to achieve the desired result. Testing begins with checking the operation of the buttons on each tab. It also checks the ability to enter plain text in each field without interrupting the software.

Сode Review

In other words, another pair of eyes looks at the source of codification. Why to review the codes? They improve the quality of our app, support programmers, build connections, and work together more efficiently. After the developer finishes working on the inconsistencies, another developer looks at the code again and solves the problems.

If you have plans to upgrade an application, add new features and expand your audience, the system review process can help you do this faster, cheaper, and more efficiently. In addition, this method will be extremely useful if the project is large, and you plan to involve new developers or delegate it to another team.

Static Code Analysis

Static analysis confirms the source code or the files that are used in the application without actually running it. Code analysis is used to automatically monitor developer’s code and apply advanced implementation methods. After achieving the results, you can review them and set priorities rules depending on your business needs. One of the advantages of static analysis is that it reduces the cost of fixing the defect. Since the sooner we detect a mistake, the lower will be the cost of fixing it.


Unit testing is also called module testing. That is, very small individual code fragments are tested. It is very important for a client to get information about their result at the end of the check. Unit testing allows you to verify the application in detail and get complete information about it. Requests made by a specialist during such inspection are fast because small sections are checked. It is also very important to use the right structure, which helps optimize the performance.

Besides, you should understand that even if you are analyzing a very small fragment, there is a chance of an error since unit tests are not flawless, and it is impossible to achieve a 100% perfect result. This analysis is suitable for detecting errors, but it is impossible to record everything since the assessment also has logical errors. Using unit tests, programmers can easily determine where the error is located, which will help to quickly fix it before contacting quality assurance specialists.

Early Stage of Development

At this stage, we communicate with the client before the development process begins. We will conduct research, study the market and an app. We submit a detailed document to the client with our findings, suggestions, and the project’s design. We discuss and make adjustments. After its approval, we start to work on the website design or the program’s interior pages. When the app is ready, a start date is assigned. However, you must understand that the progress of the application does not end with startup.

Product Testing Before Launch

We must receive feedback at each step in order to evaluate the progress of the development stage. At this point, we can fix the errors detected during testing. Since this will help ensure product quality and allow the developers to fix bugs before the actual launch.

When the program is ready and its functionality is tested, the problems that have arisen at different levels are discussed and marketing research is carried out. This is one of the stages of product development and pre-launch verification, which many developers skip because they consider it not so important. Thus, we will not only eliminate the problems associated with the product code, but also make it well-selling, as well as conduct the analysis that will be needed in the future.
