System Testing. Take Action and Get Ahead
System or system-level testing helps to identify performance problems in a software product under development in a timely manner. It is usually performed before acceptance testing (which checks how the developed product meets business requirements and end-user needs) and after integration testing (when different blocks, modules or components of a software application are evaluated as a unified object).
System-level testing verifies that all types of user input match the expected result, and finds bugs that QA may have missed during development testing.
Any system or software defect can have serious consequences. The life and health of a consumer could be at stake behind a software bug. Therefore, testing of interconnected systems is an attractive condition for releasing a software product. Just think of Nissan, which had to recall more than 1 million cars in 2014 due to a defect in airbag sensors after system testing.

Improve product quality
It is impossible to avoid mistakes in the development process. This is a common situation. System testing checks the code and functionality of the system to ensure that it meets the requirements. Errors that may have been missed during integration and unit analysis are identified during system testing.
The integrated system is tested through several sets of tests in the product development cycle. These tests show whether the product can run successfully on different platforms and environments.

Economy and security
Fixing a system defect discovered late in the execution phase can affect the speed and lifecycle of the entire project and the final product. Timely and continuous system testing not only reduces unexpected costs, but also allows project managers to better control budgets.
Well tested products are reliable. How do you know that the system under test is free of potential vulnerabilities? System testing should control risks and block potential threats to end users and system data, providing insight into the stability of the product at every stage of development.
Software Productivity
It is difficult and costly to change code that has already gone into production. System testing detects problems in the code while it is still being debugged. System performance is tested across platforms, operating systems and browsers.
Performance-based system testing can track system behaviour: memory usage, CPU usage, latency. These tests identify critical performance issues and show which element of the workload or part of the system is causing performance degradation.
System testing typically uses a variety of software verification techniques that determine the overall test coverage of an application and help identify critical defects.

Common types of system testing:
Performance testing. Performance testing measures the speed, average load time, stability, reliability and peak response time of a system under various conditions. This testing evaluates: response time, request processing speed, load testing and system scalability testing.
Usability testing. This is testing for ease of use and functionality. Metrics used during testing include: user error rate, success rate, time it takes a user to complete a task, and user satisfaction.
Load testing shows how the system or software performs under real extreme load and test scenarios. Qualitative measures of this phase include throughput, number of users and latency.
Regression testing is responsible for the functionality of existing systems or software. Also known as performance testing, it ensures that any changes made to the application or code during system testing, recent code changes or upgrades have not caused new bugs or problems.
Migration testing is carried out when legacy systems are migrated to new systems without disruption, data loss or downtime.
Scalability testing measures the ability of the software to adapt to increases or decreases in its functionality.
Security testing measures how secure the system is against vulnerabilities and attacks. It tests: authentication mechanisms, authorisation, user input processing, vulnerabilities, resistance to various types of attacks.
Functionality testing involves running various scenarios to check: basic functionality, interaction between modules and components, correctness of data processing.

Sapsan Plus
The programmers of Sapsan Plus s.r.o. use the approach of continuous testing and integration from the early stages of development. This allows us to automate testing processes as much as possible and provide fast feedback. The Sapsan team is proactive: they fix problems even before the software is launched or updates are implemented.
