Description
Technical field
The invention proposes a kind of self-adapting random test methods divided equally based on iteration region with positioning, use for testing
The generation of example, belongs to the technical field of test automation.
Background technique
With the continuous expansion of software market, software size is caused to increase increasingly, software function is increasingly complicated, how to ensure
The quality of software product becomes an important research hotspot, and software test undoubtedly becomes ensures the important of software quality
Link.For software test, scientific research personnel proposes many software testing technologies, and wherein, random test is due to the letter of its concept
It singly and can automate, receive more and more attention, existing random test process is as shown in Figure 1.
Random test can detecte out mistake that people fail to predict (and the detection of this mistake seem can only by with
Machine test is accomplished), still, exist from beginning to end for the dispute of random test, and this dispute is mainly due to random test
Only test case is randomly generated in blindness, never considers the information of test case executed, so, scientific research personnel couple
Great controversial is produced in the efficiency of random test.
Meanwhile Chan et al. has found, the performance of software test is influenced by Software failure modes, and so-called failure mode is exactly
Refer to the distribution pattern in software failure region.They have found that continuous type distribution is often presented in software failure region.Chan et al. is total
Knot proposes three kinds of failure modes: (i) bulk mode, as shown in a of Fig. 3.(ii) bar like pattern, as shown in the b of Fig. 3.
(iii) dotted mode, as shown in the c of Fig. 3.Meanwhile they point out, blocky and bar like pattern is more more universal than dotted mode.
Since failed areas is successional, it is reason to believe that, it is not that the region of failed areas should also be continuity
, so, that give the very big inspirations of scientific research personnel: when test case is uniformly distributed, will increase test case and finds failure area
The chance in domain.Based on this inspiration, Chan et al. proposes ART (self-adapting random test) method.
Traditional FSCS_ART (self-adapting random of fixed size Candidate Set is tested) method, by constantly calculating distance,
Reach being uniformly distributed for test case, but this method has very big time overhead, and pass through the adaptive of region division
Random testing method, although time overhead is small, performance is bad, thus the invention proposes based on iteration divide equally and position
Self-adapting random test method both saves time overhead, while improving based on the adaptive of region division in conjunction with two kinds of thoughts
Answer the performance of random testing method.
