What does the Efficiency field in the Karate output table represent? Efficiency compared to what?

问题

I was wondering as to what the Efficiency field in the Karate output table in the console represent. I see it has a value of 0.98 after i execute my tests, so it is 98% efficient. But compared to what?

Seems no one had this question earlier i suppose.

回答1:

Simple search through the source (https://github.com/intuit/karate/blob/9992eaf8d7b9dd637477a0970de1a1187b820fc2/karate-core/src/main/java/com/intuit/karate/Results.java#L163)

tells us that:

public double getEfficiency() {
    return timeTakenMillis / (getElapsedTime() * threadCount);
}

If I understood the metric correctly, it means how efficiently we are using threads. If efficiency == 1 then all threads are fully used.

The metric doesn't give any meaningful information unless you have more than 1 thread.
