Soft test road-the world of code, soft test road
After taking the soft test, I first came into contact with the knowledge of computer systems. It mainly introduced the structure and principles of computers, which are very abstract.
We all know that operations on computers are performed in binary format. However, since
C # Inside the socket has asynchronous and synchronous points, can refer to: Https://docs.microsoft.com/en-us/dotnet/framework/network-programming/socket-code-examples to learn. Many examples of DirectSound socket sound collection on the network, but are a separate tool class (such as: Directsoundcapture), took a bit of time to implement the socket call, by the way sum up share. The following illustration is a tes

JUNIT4 IntroductionJUnit is a simple framework that can write repetitive tests and is an example of a unit test framework based on the Xunit architecture. JUNIT4 is the largest ever improvement in the JUnit framework, and its main goal is to simplify the writing of test cases with the annotation features of JDK 5. JDK
feature exists. Test declares that it has an open, committed, closed feature, but does not have a rollback feature, and the transation in test is the most important to decide whether or not to commit to the database, which plays a role in protecting the data site.2. When integrating spring MVC, classes with @service are not scanned in the MVC configuration file, which causes transactions to become normal b
Database tool sysbench installation tutorial and performance testing example sysbench is a modular, cross-platform, multi-thread benchmark testing tool that is mainly used to evaluate the database load of different system parameters. For details about this project, see: http://sysbench.sourceforge.net.
It mainly includes the following testing methods:1. cpu performance2. disk I/O performance3. Scheduler Performance4. memory allocation and transmissio
exceptions, consider the following:
1. What did the application do to cause this exception?For example, is it data binding? Or get data through serialization and deserialization? Or reflection?
2. Is this exception common?For example, if this exception occurs when an object is serialized, you need to check and test each serialized part.
3. Use reflectio

Unit Test
Unit tests are used to test the correctness of a module, a function, or a class.
For example, for the function abs (), we can write the following test cases:
1. Enter a positive number, such as 1, 1.2, 0.99, expecting the return value to be the same as the input;
2. Enter negative numbers, such as-1,-1.2,-0.9
easy to do processing.
The front end code is as follows:

This paper compares and analyzes the performance problem of random function Mt_rand () and Rand () in PHP. Share to everyone for your reference. The specific analysis is as follows:
in PHP Mt_rand () and Rand () functions are randomly generated a pure number, they need us to set up the seed data and then generate, then Mt_rand () and Rand () that performance will be better, the following we have questions to test.
in more detail, we only take an interface to illustrate how to test this interface--/note/readnotes
