Ich verwende Karma für Winkel 2 Einheit Test .It funktioniert gut, aber ich habe eine Sache, die ich nicht weiß, warum es passiert. Mit Karma, wenn ich Testfälle laufen lasse, jede Funktion, die ich teste, läuft zweimal .Ich wusste dieses Problem, wenn ich console.log auf dieser Funktion ausgab, die ich im Testfall verwendete. Ich weiß nicht, warum dies geschah mir.Bitte helfen Sie mir.Karma Lauf Testfälle Doppel
Ich verwende es mit Webpack.
webpack: bundle is now VALID.
