Concordion execute命令可用于以重复方式运行concordion fixture的操作.例如，如果我们想以列表的形式说明具有多个示例的需求，那将非常有用.
考虑以下要求 :
<ul> <li>The full name Robert De is to be split as <ul> <li>Robert</li> <li>De</li> </ul> </li> <li>The full name John Diere is to be split as <ul> <li>John</li> <li>Diere</li> </ul> </li> </ul>
如果我们想要为分割函数写一个规范，将一个名称拆分为它的名字和姓氏，那么规范将如下 :
<ul> <li>The full name <span concordion:execute = "#result = split(#TEXT)"> Robert De</span> is to be splited as <ul> <li><span concordion:assertEquals = "#result.firstName">Robert</span></li> <li><span concordion:assertEquals = "#result.lastName">De</span></li> </ul> </li> <li>The full name <span concordion:execute = "#result = split(#TEXT)"> John Diere</span> is to be splited as <ul> <li><span concordion:assertEquals = "#result.firstName">John</span></li> <li><span concordion:assertEquals = "#result.lastName">Diere</span></li> </ul> </li> </ul>
当Concordion解析文档时，它会将特殊变量#TEXT的值设置为当前元素的值为"Robert De"并传递它分裂功能.然后它将使用execute命令执行带有#TEXT参数的split()方法，并将结果设置为#result变量并使用result，打印firstName和lastName值作为输出.
让我们使用一个有效的Eclipse IDE，并按照下面给出的步骤创建一个Concordion应用程序 :
| Step | 描述 |
|---|---|
| 1 | 创建一个名为 concordion 的项目并创建一个包 com. it1352在创建的项目中的 src 文件夹下. |
| 2 | 使用添加外部JAR 选项添加所需的Concordion库，如 Concordion - First Application 章节中所述. |
| 3 | 在 com.IT下创建Java类系统屋包. |
| 4 | 在 specs.it1352包下创建Fixture类 SystemFixture . |
| 5 | 在下创建规范html System.html specs.it1352包. |
| 6 | 决赛步骤是创建所有Java文件和规范文件的内容并运行应用程序，如下所述. |
这里是System.java文件的内容 :
package com.it1352;
import org.concordion.api.MultiValueResult;
public class System {
public MultiValueResult split(String userName){
MultiValueResult result = new MultiValueResult();
String[] words = userName.split(" ");
result.with("firstName", words[0]).with("lastName", words[1]);
return result;
}
}以下是SystemFixture.java文件的内容 :
package specs.it1352;
import org.concordion.api.MultiValueResult;
import org.concordion.integration.junit4.ConcordionRunner;
import org.junit.runner.RunWith;
import com.it1352.System;
@RunWith(ConcordionRunner.class)
public class SystemFixture {
System system = new System();
public MultiValueResult split(String userName){
return system.split(userName);
}
}以下是System.html文件的内容 :
<html xmlns:concordion = "http://www.concordion.org/2007/concordion"> <head> <link href = "../concordion.css" rel = "stylesheet" type = "text/css" /> </head> <body> <h1>System Specifications</h1> <p>We are building specifications for our online order tracking application.</p> <p>Following is the requirement to split full name of a logged in user to its constituents by splitting name by whitespace:</p> <div class = "example"> <h3>Example</h3> <ul> <li>The full name <span concordion:execute = "#result = split(#TEXT)"> Robert De</span> is to be splited as <ul> <li><span concordion:assertEquals = "#result.firstName"> Robert</span></li> <li><span concordion:assertEquals = "#result.lastName"> De</span></li> </ul> </li> <li>The full name <span concordion:execute ="#result = split(#TEXT)"> John Diere</span> is to be splited as <ul> <li><span concordion:assertEquals = "#result.firstName"> John</span></li> <li><span concordion:assertEquals = "#result.lastName"> Diere</span></li> </ul> </li> </ul> </div> </body> </html>
完成创建源文件和规范文件之后，让我们将应用程序作为JUnit Test运行.如果您的应用程序一切正常，那么它将产生以下结果 :
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\concordion\specs\it1352\System.html Successes: 4, Failures: 0
System.html是Concordion测试运行的输出.
