Some Basic Concepts
Test FixtureA test fixture represents the preparation needed to perform one or moretests, and any associate cleanup actions. This may involve, for example, creating temporary or proxy databases, directories, or starting a serverprocess.Test CaseA test case is the smallest unit of testing. It checks
this parameter.2.API modeIn addition to using the command line, you can call the coverage module directly in Python code to perform code coverage statistics. The method of use is also very simple: Import coverage CoV = coverage.coverage (Source = [' totest ']) Cov.start () #coding Cov.stop () Cov.report () Cov.html_report (directory= ' covhtml ') SOURCE specifies the file to perform statistics, Source = [' totest '] only statistics totest.py coverage directory specifies the path to generate HTM
The basic method for unit testing is to call the testedCodeFunction, enter the parameter value of the function, obtain the returned results, and then compare them with the expected test results. If they are equal, the test is passed. Otherwise, the

If you have such a file in your project mylib.py, there are a number of methods written in the file for the outside people to calldefAdd (x, y):returnx+ydefDivision (x, y):returnx/ydefmutiply (x, y):returnx*ydefsubtract (x, y):returnX-ydefMain ():Passif __name__=='__main__': Main ()So how do we write unit test code to verify the correctness of these methods?Take a look at the following file testadd.py (file
ANGULARJS Unit Test
There are many tutorials on the web for unit testing, such as how to install Jasmine and ngmock, and you can search for them. It's not here to say. The following focuses on the process of a unit test.
Load a module
Angularjs uses a module to include di
When a programmer writes a complete program, does he or she ensure that the program is correct? Of course, to test, programmers usually write a program to test the correctness of the target program. Such tests are programmer tests, known as white-box testing, because programmers know how the software being tested accomplishes functions and what (What) functions are done. This programmer-based

Project often encountered such a problem, the written module, due to changes in the requirements of the database field has been modified, the logic has some changes, so, in a large number of code changes, run the interface to start testing. Helpless at once cannot write to all logic, or even misspelled characters. Especially when doing B/s system, debugging a good function, often cost you a lot of time. And, if there are any changes, you have to do it again, and if you encounter some relationshi

Consider decoupling.
The point is that the code is written as a class, the way it looks.
Don't be process-oriented. One line after the other. If this is the case, you won't be able to test it without adding a breakpoint.
But adding breakpoints is not what we're a

cumbersome, IntelliJ idea provides a very handy plug-in: JUnit generator, which automatically generates JUnit test code. The specific installation method is:
Open Settings (ctrl+alt+s) to find plugins
Enter Junit generator V2.0 in the Plugins search box and click Install
Back to the class file we wrote earlier, Alt+insert, choose JUnit 4

1. testing only requires testing of logical operations and testing of crud data. The collection and display of front-end UI data is not done by nunit. Our task is to ensure that the data transmitted to the UI is correct.
In the standard demo, I only tested BLL and Dal layers.
2. it is best to separate the test database from the database u
