Software testing

Software Testing is a process used to evaluate the functionality, reliability, compatibility and security of a software application or system. It involves testing the behavior of the system against a set of predetermined expectations and objectives. The purpose of software testing is to help detect any existing or potential errors, omissions, or bugs within the code, ensuring that the system runs as expected.

Software testing is typically performed in a process called verification and validation. This process includes tests such as unit tests, integration tests, system tests, regression tests, and stress tests. The values and objectives to be tested will vary from project to project. For example, an integrated system test is used to determine how the different components of a system will work together, while a unit test focuses on verifying the behavior of an individual piece of code.

Software testing can be performed manually or through automated means. Automated tests may involve the use of specific tools and applications to carry out tests in a more efficient and precise way. Automated testing is essential for systems where manual testing may be too time-consuming or too costly for the project budget.

Software testing can be an important part of the software development cycle and can help ensure that only quality, secure software is released into the market. As such, it is important for software developers and testers to understand the importance of software testing and the processes and tools available to help them get the results they need.
