SMURF Testing

Google introduced new mnemonic for test quality attributes - SMURF:
📌 Speed: Unit tests are faster than other test types so they can be run more often.
📌 Maintainability: Cost of debugging and maintaining tests.
📌 Utilization: A good test suite optimizes resource utilization, fewer resources cost less to run.
📌 Reliability: Sorting out flaky tests wastes developer time and costs resources in rerunning the tests.
📌 Fidelity: High-fidelity tests come closer to approximating real operating conditions. So integration tests have more fidelity than unit tests.

In many cases improving one quality attribute can affect the others, so be careful and measure your costs and trade-offs.
