How does a time limit relate to the variance strategy?

I'm wondering how, in a load test, the time limit relates to the variance strategy.

Using these settings, it seemed like the test just kept going and going:
Threads: 10
Strategy: Variance
Interval: 10
Variance: 0.5
Limit: 1 second

Also, I'm assuming "min," "max" and "avg" are in milliseconds. Is this correct?

Thanks!

    Hi Alex,


    Time limit defines the time period during which variance strategy will be applied to creation of threads used for load testing.

    The line representing a number of load testing threads over time would look like a chainsaw:
    1. starting at startThreadCount
    2. linearly increasing the thread count  to startThreadCount + startThreadCount*variance
    3. linearly decreasing the thread count  to startThreadCount - startThreadCount*variance
    4. linearly increasing the thread count to startThreadCount

    An example in User Guide (look for LoadTest Variance Strategy) also explains this.

    Your assumption is correct - min, max and avg are values in milliseconds in load test reports.


    Cheers!
