Do you have experience conducting test checks and analyzing the quality of software products?

Yes, conducting test checks and analyzing the quality of software products is an important part of development.

Typically, the following actions are performed within this practice:

• Developing and executing unit tests to verify the correctness of individual components.
• Conducting integration tests to verify interactions between modules.
• Using automated testing frameworks (e.g., pytest for Python).
• Analyzing code coverage to assess the completeness of testing.
• Performing functional and regression testing.
• Using static code analysis tools and quality check tools (linters, analyzers).
• Collecting and analyzing quality metrics such as defect count, response time, and performance.

An example of a simple Python test using pytest:

# test_example.py

def add(a, b):
    return a + b


def test_add():
    assert add(2, 3) == 5
    assert add(-1, 1) == 0

Running such tests helps identify errors early and maintain code quality.
