Fig. 5. Medians of the normalized number of faults detected for each class over time; their median

test run represents the percentage of faults found in that test run against all faults that
we know in the class. The medians of the number of the normalized faults detected over
time for each class are shown in Figure 5. The thick curve is the median of the medians
of the number of normalized faults detected over time for all classes.
