Mistaken rule of thumb method is largely carried out, is made in the past with people testing the results of analysis of the defects revealed by the regularity for the intuitive guesses to discover defects. Using a dichotomy search procedure, typically a few test cases can be listed below: Table retrieved only one or empty table; table is exactly the number of entries in powers of 2; Table 2 the number of items than a power of more than 1 and so on. cellular phone jammerwill be tested in the testing center ofcell phone jammer. Mistaken method full human experience, in a test group brainstorming, convenient and practical, especially in poor foundation in software testing in the case, well organized test group (you can also have external personnel) error guessing, is effective test methods. The test parameter is a random number. It can automatically generate, so the high degree of automation. A large number of random test cases using test procedures will increase user confidence in the process. But the key is whether the law of random numbers using practical.
