Test All Process and Routes of Apache Camel Junit

问题

I am trying to validate all the processes of route but start is working fine after that it started to break.Please give me some useful reference or sample for this.Thanks in advance.

test.txt:

F1:L1
F2:L2
F3:L3

Customer.java

    private String firstName;
    private String lastName;
    // getters and setters
    @Override
    public String toString(){
        return firstName +":::" + lastName;
    }
}

JUnit and Route:

    public class FileTest7 extends CamelTestSupport {

        @EndpointInject(uri = "direct:teststart")
        private Endpoint start;

        @EndpointInject(uri = "mock:direct:process1")
        private MockEndpoint mockProcess1;

        @EndpointInject(uri = "mock:direct:process2")
        private MockEndpoint mockProcess2;

        @EndpointInject(uri = "mock:direct:process3")
        private MockEndpoint mockProcess3;

        @EndpointInject(uri = "mock:direct:write2File")
        private MockEndpoint mockWrite2File;

        @EndpointInject(uri = "mock:end")
        private MockEndpoint mockEnd;

回答1:

The CamelContext is not automatically started by the test framework because you are using AdviceWith, to allow you to add advice to routes before they start. Add a call to startCamelContext() at the end of doPostSetup after you've added the advice.

Also, append doesn't appear to be a valid property of the file component so you'll need to remove append=true.
