Switch case is a qualified data in js, which is much simpler than if else. Next I will introduce my understanding of js switch case. In the if Condition Statement, only one logical condition can exist. if multiple conditions exist, you can use nested if statements to solve the problem. However, this method increases the complexity of the program, reduce program readability. The switch flow control statement

The automated regression test case evaluation criteria try to define different dimensions to evaluate the advantages and disadvantages of automated cases, which serves as the basis for subsequent evaluation and discussion of the test framework, test technology, and test case writing mode. So what is a good automated regression test case? In short, it is a

Commonality: All of the common use cases are extracted from the public part of the information, as a separate use case, and then through the different methods to reuse the common use case, to reduce the workload of model maintenance.1.

Speaking TestUse CasesDesign, I think every test engineer who has been tested will think it is very simple, not that: design according to requirements or outline, get the software function division diagram, and then according to each function, use Case design using equivalence classification, critical value, and cause/effect. But in fact, the design of the test data is not discussed. Just for the test items, we find that experienced testers for the sa

exist This table is clearly present, why can't the program find the table??Reason Lookup:because MySQL is the default for Linux to differentiate table name casing . MySQL case sensitivity setting is determined by the parameter lower_case_table_names, where:1) lower_case_table_names = 0Case-sensitive (that is, case sensitivity to table names), which is the default setting. When this is set, the tabl

What is use case The writing of case description documents is a reflection of the deep understanding of user requirements by system analysts. It is an important basis for later time sequence diagrams and actual development. It can also be used as a basis for project estimation, as well as to measure the efficiency of developers Based on UC complexity and development cycle. Therefore, the writing standard o

Commonalities: the common information is extracted from the existing use cases. As a separate use case, different methods are used to reuse this public use case, to reduce the workload of model maintenance. 1. include) Inclusion relationship: Use Inclusion cases to encapsulate a group of similar actions (behavior fragments) that span multiple use cases, so that multiple Base use cases can be reused.

When I started to paint, I found out that it was purely a teacher's job. Listen to understand or feel that you understand that it is just an illusion. For the UML diagram or understanding is not thorough enough, of course, now ask yourself to be thorough is also a dream. Although it is an illusion, trait also let me watch the video when I feel happy. Furtherm
