Question

如何在每个测试套件中初始化一次变量，以便它们在每个测试中都可见？它可以是例如加载一些文件，每个文件都需要进行测试。

Answer 1

根据Matlab xUnit文档：您可以1）继承TestCase或2）使用子功能。使用子功能的示例如下所示。您只能传递一个变量，因此必须在结构中加载它们，如下所示。您可以在结尾处添加其他子功能，但请确保使用“setup”，“test”或“teardown”开始或结束其名称

function test_suite = testjkcmInputParser    
    initTestSuite;

    function d = setup
    d.file='garbagelog.log';
    d.fid = fopen(d.file, 'w');
    d.o = jkcmInputParser(d.fid);

    function teardown(d)
    delete(d.o);
    fclose(d.fid);
    delete(d.file);

    function testConstructorNoInput(d)
    %constructor without fid
    delete(d.o);
    d.o = jkcmInputParser();    
    assertEqual(isa(d.o,'jkcmInputParser'), true, 'not a jkcmInputParser');
    assertEqual(isa(d.o,'inputParser'), true, 'not an inputParser');

    function testConstructorWithInput(d)
    %constructor with fid    
    assertEqual(isa(d.o,'jkcmInputParser'), true, 'not a jkcmInputParser');
    assertEqual(isa(d.o,'inputParser'), true, 'not an inputParser');
    initializejkcmParser(d.o);      
    s = d.o.printHelp();    
    assertEqual(s, correctPrintHelp(), 'output of printHelp does not match expected.');

    function outP = initializejkcmParser(o)
    %setup jkcmInputParser
    o.addRequired('val1_noComment', @isnumeric);
    o.addRequired('val2', @isnumeric, 'comment');    
    o.addOptional('val3_noComment',3, @isnumeric);
    o.addOptional('val4',15, @isnumeric, 'another great comment!');    
    o.addParamValue('val5_noComment', 45, @isnumeric);
    o.addParamValue('val6', 45, @isnumeric, 'This is the greatest comment');
    outP = o;

    function outP = correctPrintHelp()
    outP = sprintf(...  
       ['val1_noComment: Req : \n',...
        'val2: Req : comment\n',...
        'val3_noComment: Opt : \n',...
        'val4: Opt : another great comment!\n',...
        'val5_noComment: Param : \n',...
        'val6: Param : This is the greatest comment\n']);

在R2013a中，MATLAB包含一个功能齐全的测试框架。它包含的功能之一是能够为整个类定义设置/拆除代码。
