When writing Android applications, we often need to write some business logic implementation classes, but we may not be able to determine whether this business logic can be successfully implemented, especially when the logic code is very large, we can not check our own code in one line, in order to solve this problem arises:Write unit test code under Android-----Junit TestThe

Time: If the unit test carefully, in the system integration is very smooth, so it will save a lot of time, whereas those because of the time reason does not do

The unittest we're going to use here is the Python unit test framework, and its website isHttps://docs.python.org/2/library/unittest.html, here we can get comprehensive information.
As we write more and more use cases, we need to consider the specification and organization of use case writing for later maintenance, and unittest is just such a tool. Here we use an example to show what

If you want to do unit testing on Android, there are two basic ways to do it.
The first is the Java programmer's most familiar and commonly used junit, but since the current Android SDK (version 1.1) only provides stubbed methods/classes, there is no specific implementation code, so if you use JUnit, We need to run the unit test with the JDK and use the Java com
of the program to discover errors in the module. Because the software module is not a separate program, in order to do unit testing also must write a lot of extra code, so as to virtually increase the workload of developers, it is a better way to solve this problem is to use the test framework. The test framework is the key to
", function () { ok (result==1, " Determine if the user name exists OK "); NotEqual (Result==1,true, "Determine if the user name exists notequal");} ); User.existusername2 (' Milan ');Test results:5, modularIn the async test above, we saw that the word "async test" was at the beginning of each use case. So how d
, this is largely due to the fact that the level of the programmer is not high enough. I think the necessary conditions for using unit tests to bring great benefits are as follows:
Programmer's own level of programming-whether there is more code experience, proficiency in refactoring
Programmer's knowledge of the project-whether the software or module needs to be understood correctly
Project Quality-whether stable, long-term multi-ver

With this hierarchical relationship, you can execute test cases of any level at any time as required by the system.

The extra "." In the back. A logical error is raised when an algorithm (which can be considered a "way to solve the problem") is incorrect. Maybe programmers forget that Python is a "0 index" and try to write
