**System testing** At the system testing stage, the behavior of the entire system as a whole is analyzed. The product's compliance with all requirements and specifications is checked. An important point here is testing the program in conditions as close to real as possible. This stage is vital for identifying component interaction defects and their impact on the overall performance of the system.
**Acceptance testing** Acceptance testing is performed to determine the readiness of the product for use. Here, the main focus is on aspects that are important to the end user: user-friendliness of the interface, completeness of functionality implementation, performance and security. The main conclusion of acceptance testing is whether the product is ready or not ready for release.

Software testing stages are often formalized, but rigidity of the model bulgaria mobile phone number list is a constraint. Tests should be flexible, adapting to the project, and not vice versa.
**Regression testing** After making changes to the program code, for example, when fixing errors or adding new functionality, regression testing is carried out. The goal is to ensure that the changes made do not disrupt the operation of previously tested and correctly functioning parts of the program.
In general, the various stages of software testing are cyclically interconnected and aimed at gradually improving the quality of the product. Combining different types of testing allows for maximum program reliability and its compliance with the initial requirements and user expectations. A well-organized testing process reduces the risk of serious defects in the final versions of the software and helps improve its quality, as well as providing a positive user experience for the end user.
