About: Smoke testing (electrical)

An Entity of Type: Abstraction100002137, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Smoke testing refers to various classes of tests of systems, usually intended to determine whether they are ready for more robust testing. The expression probably was first used in plumbing in referring to tests for the detection of cracks, leaks or breaks in closed systems of pipes. By metaphorical extension the term is used in electronics. In Lessons Learned in Software Testing, Cem Kaner, James Bach, and Brett Pettichord provided the origin of the term: "The phrase smoke test comes from electronic hardware testing. You plug in a new board and turn on the power. If you see smoke coming from the board, turn off the power. You don't have to do any more testing."

  • Smoke testing refers to various classes of tests of systems, usually intended to determine whether they are ready for more robust testing. The expression probably was first used in plumbing in referring to tests for the detection of cracks, leaks or breaks in closed systems of pipes. By metaphorical extension the term is used in electronics.

  • 电子学及電機工程學中的冒煙測試或送電測試是指開發中的電路第一次送電，若有元件接錯或電路短路，可能會冒煙，因此稱為「冒煙測試」。冒煙可能是因為電阻器過熱所造成。有些電路若有問題，可以用自耦變壓器供電，慢慢的將電壓加大，並且監控其電流，雖然最後電路無法正常動作，但可能可以避免冒煙的情形。 積體電路過載常會產生藍色煙雾，或稱為魔法烟雾。有些笑話是以這個為主題，將這個視為是電路中的精靈：「電路是靠藍色煙雾動作的，若讓藍色煙雾跑出來，電路就不會動作了」。 (zh)
