java - 无法在测试行为调用的 Java 函数中使用 Citrus 变量

Question

我想在测试中循环以实现一种行为，该行为将使用从“消息模板(文件)”构建的消息响应某些请求，其中我将一些字符串替换为柑橘测试变量的值和索引环形。我想我几乎成功了，但不幸的是，当我尝试在我的行为中使用 ReplaceAll String 函数时，我的测试崩溃了。请参阅下面我编写的代码片段，其中删除了所有不必要的部分，以便希望使我的问题易于理解

   public class myBehavior extends AbstractTestBehavior {

        private String payloadData;

        myBehavior withPayloadData(String payload) {
            this.payloadData = payload;
            return this;
        }

        @Override
        public void apply() {
            echo("[behavior] - OK ->behavior is invoked");
            echo("[behavior]" + payloadData + " - OK ->variable from Test is correctly transmitted to behavior");
            echo(func_asis(payloadData));
            echo(func_replace(payloadData));  // if you uncomment this line the test will crash at starting time when invoking replace_all
        }


        String func_asis(String myvar)
        {
          String s = "This is a string in which nothing is replaced, OK fine !";
          echo("[func_asis] OK ->in func_asis now ");
          echo("[func_asis] myvar="+ myvar + " - OK ->variable from Test is correctly transmitted to func_asis");
          return s;
        }

        String func_replace(String myvar)
        {
          String s = "This is a string in which to replace !!Name!! by the value of my citrus variable but it crashes";
          echo("[func_replace] OK ->in func_replace");
          echo("[func_replace] myvar="+ myvar + " - OK ->variable from Test is correctly transmitted to func_asis");
          //s=s.replaceAll("!!Name!!",myvar); // This will crash when starting the test (not actually when running it) !!!
          return s;
        }

    }

    @CitrusTest 
    public void mySimpleTest() throws IOException {
      description("Simple Test invoking a behavior which it self will invoke a java function");
      variable("vm", "/dc/vm/folder/vm_basename");

      repeat().until("i = 3")
            .actions(
              sleep(1000L),
              applyBehavior(new myBehavior().withPayloadData("${vm}${i}"))
            ); 
    }

• 以下是在 func_replace 中注释了 ReplaceAll 调用的测试输出。

非常感谢任何解决此问题的想法

Answer 1

投入更多时间后，我开始了解 Citrus 如何处理变量，在上面的情况下，“myvar”的值实际上设置为“${vm}${i}”，并将在执行时被替换时间，但是当从测试操作调用时......所以我查看了自定义测试操作，发现即使有时变量实例化也有点棘手......但尽管如此，我仍然可以实现我想做的第一部分就是用变量内容替换字符串中的一些预定义值。请参阅下面执行此操作的代码片段。

...但是现在因为我从操作中调用替换函数，所以我无法将字符串返回给调用者，而这正是我计划在行为中执行的操作...因此将调查是否以及如何可能或将看看我的测试的一些其他设计(比如存储字符串的临时文件，其中替换值在 func_replace 更新它们之后由行为读取。)无论如何，这是我上面遇到的问题的解决方案:

@Test
public class CitrusLearningL4 extends TestNGCitrusTestDesigner {

    public class myBehavior extends AbstractTestBehavior {

        private @CitrusResource TestContext parentContext;        

        myBehavior withContext(@Optional @CitrusResource TestContext context) {
            this.parentContext=context;
            return this;
        }

        @Override
        public void apply() {
            echo("[behavior] - OK ->behavior is invoked");
            func_replace();
            echo("[behavior] - OK ->behavior is finished");

        }

        void func_replace()
        {
          final String s = "This is a string in which '!!Name!!' is present because it was replaced by the value of my test variable";
          echo("[func_replace] OK ->in func_replace");
          action(new AbstractTestAction() {
                public void doExecute(TestContext context) {
                  String s1 = s;
                  System.out.println("[anAction] - OK ->anAction is invoked"); 
                  String sVar=String.format("%s", (String) parentContext.getVariable("vm") + (String) parentContext.getVariable("i"));
                  System.out.println("[anAction] - OK ->" + s1.replaceAll("!!Name!!",sVar));      
                }
              });         
        }

    }

    @Test @Parameters("context")
    @CitrusTest 
    public void mySimpleBehaviorTest(@Optional @CitrusResource TestContext context) throws IOException {
      description("Simple Test invoking a behavior which it self will invoke a java function");
      variable("vm", "/dc/vm/folder/vm_basename");

      repeat().until("i = 3")
            .actions(
              sleep(1000L),
              applyBehavior(new myBehavior().withContext(context))
            ); 
    }

}
