testikoodi
Testikoodi, or test code, is source code written to exercise and verify the behavior of software products. It is usually part of a test suite and serves to detect defects, prevent regressions, and document expected behavior through automated checks. Test code runs against the system under test with controlled inputs and asserts expected outputs, states, or interactions.
Test code is organized into layers: unit tests (isolated components), integration tests (interactions between components), and
Quality considerations emphasize determinism, speed, and maintainability. Tests should be readable, independent of execution order, and
In practice, testikoodi is integrated into development workflows via frameworks and continuous integration. Popular tools include
The term testikoodi is common in Finnish software practice and aligns with standard software testing methodologies.
