Example 1 with Dim

use of org.eclipse.test.internal.performance.data.Dim in project eclipse.platform.releng by eclipse.

the class Performance method assertPerformanceInRelativeBand.

/**
 * Asserts that the measurement specified by the dimension captured in the given performance meter is within a certain range

 * effect.

 *            the performance meter
 * @param dim
 *            the Dimension to check
 * @param lowerPercentage
 *            a negative number indicating the percentage the measured value is allowed to be smaller than some reference value
 * @param upperPercentage
 *            a positive number indicating the percentage the measured value is allowed to be greater than some reference value
 * @throws RuntimeException
 *             if the properties do not hold
