Brief introduction
Integration testing is primarily about testing the interactions between multiple controller, and testing the more important workflows in the application to verify that these workflows are in line

Before this, you need to start zookeeper for service governance (standalone).

Storm and Kafka single-host functions are well integrated, but some problems occur in the storm Cluster Environment and data processing performance. The test process and problems are briefly recorded as follows:
Performance Indicator: at least 1 million of the information is processed per minute (about bytes in CSV format). The information is parsed and persisted to the DB.

Code algorithm correctness (as far as possible through manual detection of Code logic errors), clarity, standardization, consistency, algorithm efficiency. And as much as possible to find errors found in the program.The second step is to find errors by designing test cases and executing the program to be tested to track comparisons between actual and expected results. Experience has shown that the use of manual static inspection can effectively detec
Unit tests:Unit testing is a test of the correctness of a software's basic constituent unit (the smallest unit of software design), such as a function, a process (function,procedure), or a method of a class.Integration testing:Integration testing is based on unit testing, which assembles all modules into subsystems or systems according to the outline design requirements, verifying that post-assembly functions and the interface between modules are prop

Welcome to Unity Learning, unity training, Unity Enterprise training and education zone, there are many Unity3d resources, unity3d training videos, unity3d tutorials, Unity3d FAQs, Unity3d Project source code, "Dog Planing Learning Network" Unity's Ultimate Academy, dedicated to building the industry Unity3d training, learning the first brand. in fact, Unity has a long test support, from the Mono Editor's unittest option, as well as the installation d
development technologies and tools and the promotion of software engineering and software process practices, software testing is becoming increasingly valued and specialized. During my testing work, I have been researching CMM, testing theory, automated testing tools, and established a complete testing system.
We will not introduce the entire test system here, but the most noteworthy part of the test: cont
The first thing to understand is that the Java for unit testing and integration testing in MAVEN is mixed, without a default directory. You need to configure which time unit tests and which are integration tests yourself.

The integration test method is divided into top-down and bottom-up two kinds.Top-down integration (Top-down integration):Starting from the main control module, move down the program level and gradually combine the modules.You can use a combination of depth-first or breadth-first strategies.Top-down
