What Is Equivalence Class Testing-木村kaela

Software Software testing is very interesting and exciting field. It is full of different notions and principles. A huge number of various practices and techniques are applied during automated testing, functional testing, usability testing, etc. Sometimes the specialists from software testing .pany perform their duties using some existed methods instinctively, without even being aware of that. It may sound strange and raise a lot of questions, but soon everything will be clear. If one asks whether the specialists have ever performed white box testing, the answer will be obvious of course they have. This checking type is widely required for the majority of clients. But if one asks the testers whether they have ever executed equivalence class testing, for some of them it may be difficult to answer. Equivalence class testing is performed with the aim to decrease the number of test cases without reducing the effectiveness of the checking procedure. It is applied when the set of various inputs should be checked. Such data sets are called equivalence classes. For example, the .pany wants to hire a full-time employee, whose age should be from 18 to 55, a part-time employee aged 16-18 and it will not hire anyone aged less than 16. A developer should write a human resources system that will automatically select employment applications. The checking of every input .bination will take much precious time. So it is a high time for equivalence class testing. This technique is based on two fundamental assumptions. What Is the Basis of Equivalence Class Testing? If one test case from the equivalence class detects a bug, then all other test cases of the same class will likely catch the same error. If one test case from the equivalence class does not detect any bug, then all other test cases of the same class will not catch that error. This technique is widely used and it is rather popular among the specialists from software testing .pany . Equivalence class testing has a range of advantages. What Are the Pluses of Equivalence Class Testing? This testing technique saves time needed to test valid input .binations, especially, if there is a huge number of possible inputs within one range. Moreover, it helps the client to save money. One may ask whether the test cases for invalid input .binations should be designed. It is very interesting question. The answer depends. In such a situation, the design-by-contract approach should be applied.
