Method Detail

run

public double run(Product product,
                  Target target)
           throws Exception

Description copied from interface: Metric

Run the test and produce a metric.

Specified by:

run in interface Metric

Parameters:

product - Product to use in test.

target - A target to use against the product.

Returns:

The resulting metric (e.g. 12.22).

Throws:

Exception - If this metric could not be obtained. This will be reported back to the Reporter.

run

public double run(Product product,
                  Object object)

Deprecated. since 1.3

Description copied from interface: Metric

Run the test and produce a metric.

Specified by:

run in interface Metric

Parameters:

product - Product to use in test.

object - A object to use against the product.
