UT ：

程序命名规范

１ 测试类的命名

测试类的命名规则是：被测试类的类名 + Test

比如有一个类叫ConfigManager，那么它的测试类的命名就是ConfigManagerTest 。

２ 测试用例的命名

测试用例的命名规则是： test + 用例方法名称

比如要测试的方法叫connectPointAdd，那么测试用例的命名就是testConnectPointAdd (说明：“用例方法”就是指被测试的类中所包含的方法，而“测试用例”就是指测试类中所包含的方法)

比如ConfigManager类中有一个方法叫做connectPointAdd，那么在ConfigManagerTest中对应的测试用例名称就是testConnectPointAdd。

保持测试的独立性

每项单元测试都必须独立于其他所有单元测试而运行，因为单元测试须能以任何顺序运行。

测试数据的覆盖率

测试时所准备的测试数据要覆盖程序中所有可能出现的CASE。

测试粒度

选择测试粒度的原则：

1、被测试类中所有public、protected方法都要测到。

2、对于简单的set和get方法没有必要做测试。

FT用例编写规范

FT自动化测试用例我们当前均采用junit编写实现，在测试用例编写中的规范与UT测试用例基本一致，除了参考UT规范外，还有以下的要求

FT用例的业务覆盖

FT用例当前是采用基于MainServiceBase基类的功能测试框架进行业务组件的功能测试，通过各个组件配合，实现的业务流程，测试用例需要穷尽各种业务的组合情况。

FT用例主要测试业务流程

FT用例是比UT用例高一个层级，主要测试组件间的功能配合，而不像UT用例主要关注接口、文件等.

工作心得：

能自动化实现的测试功能，就尝试用自动化。自动化的收益在后续整个开发过程中会体现出来。当然，自动化的代码也需要易维护，这样自动化也容易扩充。

FT的作用：版本迭代过程中，通过FT验证，减小新增代码引入bug的担心。

positional arguments:

  paths                 list of the filename/paths.

optional arguments:

  -h, --help            show this help message and exit

  --version             show program‘s version number and exit

  -l LANGUAGES, --languages LANGUAGES

                        List the programming languages you want to analyze. if

                        left empty, it‘ll search for all languages it knows.

                        `lizard -l cpp -l java`searches for C++ and Java code.

                        The available languages are: cpp, java, csharp,

                        javascript, python, objectivec, ttcn, ruby, php,

                        swift, scala, GDScript

  -V, --verbose         Output in verbose mode (long function name)

  -C CCN, --CCN CCN     Threshold for cyclomatic complexity number warning.

                        The default value is 15. Functions with CCN bigger

                        than it will generate warning

  -f INPUT_FILE, --input_file INPUT_FILE

                        get a list of filenames from the given file

  -L LENGTH, --length LENGTH

                        Threshold for maximum function length warning. The

                        default value is 1000. Functions length bigger than it

                        will generate warning

  -a ARGUMENTS, --arguments ARGUMENTS

                        Limit for number of parameters

  -w, --warnings_only   Show warnings only, using clang/gcc‘s warning format

                        for printing warnings.

                        http://clang.llvm.org/docs/UsersManual.html#cmdoption-

                        fdiagnostics-format

  --warning-msvs        Show warnings only, using Visual Studio‘s warning

                        format for printing warnings.

                        https://msdn.microsoft.com/en-us/library/yxkt8b26.aspx

  -i NUMBER, --ignore_warnings NUMBER

                        If the number of warnings is equal or less than the

                        number, the tool will exit normally; otherwise, it

                        will generate error. If the number is negative, the

                        tool exits normally regardless of the number of

                        warnings. Useful in makefile for legacy code.

  -x EXCLUDE, --exclude EXCLUDE

                        Exclude files that match this pattern. * matches

                        everything, ? matches any single character,

                        "./folder/*" exclude everything in the folder

                        recursively. Multiple patterns can be specified. Don‘t

                        forget to add "" around the pattern.

  -t WORKING_THREADS, --working_threads WORKING_THREADS

                        number of working threads. The default value is 1.

                        Using a bigger number can fully utilize the CPU and

                        often faster.

  -X, --xml             Generate XML in cppncss style instead of the tabular

                        output. Useful to generate report in Jenkins server

  -H, --html            Output HTML report

  -m, --modified        Calculate modified cyclomatic complexity number

  -E EXTENSIONS, --extension EXTENSIONS

                        User the extensions. The available extensions are:

                        -Ecpre: it will ignore code in the #else branch.

                        -Ewordcount: count word frequencies and generate tag

                        cloud. -Eoutside: include the global code as one

                        function. -EIgnoreAssert: to ignore all code in

                        assert. -ENS: count nested control structures.

  -s SORTING, --sort SORTING

                        Sort the warning with field. The field can be nloc,

                        cyclomatic_complexity, token_count, p#arameter_count,

                        etc. Or an customized field.

  -T THRESHOLDS, --Threshold THRESHOLDS

                        Set the limit for a field. The field can be nloc,

                        cyclomatic_complexity, token_count, parameter_count,

                        etc. Or an customized file. Lizard will report warning

                        if a function exceed the limit

  -W WHITELIST, --whitelist WHITELIST

                        The path and file name to the whitelist file. It‘s

                        ‘./whitelizard.txt‘ by default. Find more information

                        in README.
