Testing is the most important stage of software development, which helps to identify errors and ensure that the product meets the requirements.

The main types of testing:

• Unit testing is the verification of individual components or functions.
• Integration testing is the verification of interaction between modules.
• System testing is the verification of the entire system.
• Acceptance Testing (UAT) — verification by the customer before launch.

Test automation:Using automated tests allows you to speed up the verification process, increase its repeatability, and reduce the likelihood of errors.

Advantages of quality testing:

• Improving the reliability of the system.
• Reducing the cost of bug fixes after release.
• Confidence in the product's compliance with customer requirements.

The integration of testing at all stages of development contributes to the creation of stable and secure software solutions.
