amount of pay increase, getting true reliability is increasing and less), and different methods are suitable for finding different types of errors, so it is better to spread QA effort into testing, code review and static analysis than to spend the entire QA budget on one of these measures. The rewards are better. Static analysis tools such as FindBugs are imprecise, but imprecise analysis is still very useful and effective for improving the quality of the software. They may emit false warnings

class of the same and different places.Because Java does not support multiple inheritance, it is possible for a class or object to use a method or property that is within several classes or objects, and the existing single-inheritance mechanism cannot satisfy the requirement. The interface has more flexibility than inheritance because there is no implementation code in the interface. When a class implements an interface, the class implements all the

1. Purpose of Unit Testing A unit test examines the "one unit" of the product's program code separately from the entire system and checks to see if the results are expected. The size of the "one unit" to be tested is based on the size of a coherent set of functions and the actual change (varies) between a category and a package (package). The aim is to test the bugs (bugs) in the program code before consoli

Java basics for Java programmer test interview 1. ==difference between equals and hashcode ① = Is used to compare whether a value is equal, or to compare whether the reference is equal, that is, to compare whether it points to the same object. ② The equals method is the method provided by the Object. Therefore, each Object has the equals method and its implementa

Python Unit Test framework PyunitThe Python Unit test framework (the Python Unit Testing framework), referred to as Pyunit, is a version of JUnit Python that is designed by the two clever guys of Kentbeck and Erich Gamma. JUnit is also the Java version of the Kent-designed Smalltalk test framework. They are standard
