      • isUseRouteBuilder

        public boolean isUseRouteBuilder()
        Use the RouteBuilder or not
        Returns:
        true then CamelContext will be auto started, false then CamelContext will not be auto started (you will have to start it manually)

      • setUseRouteBuilder

        public void setUseRouteBuilder​(boolean useRouteBuilder)

      • isDumpRouteCoverage

        public boolean isDumpRouteCoverage()
        Whether to dump route coverage stats at the end of the test.

        This allows tooling or manual inspection of the stats, so you can generate a route trace diagram of which EIPs have been in use and which have not. Similar concepts as a code coverage report.

        You can also turn on route coverage globally via setting JVM system property CamelTestRouteCoverage=true.

        Returns:
        true to write route coverage status in an xml file in the target/camel-route-coverage directory after the test has finished.

      • isUseAdviceWith

        public boolean isUseAdviceWith()
        Override when using advice with and return true. This helps knowing advice with is to be used, and CamelContext will not be started before the advice with takes place. This helps by ensuring the advice with has been property setup before the CamelContext is started

        Important: Its important to start CamelContext manually from the unit test after you are done doing all the advice with.

        Returns:
        true if you use advice with in your unit tests.

      • isCreateCamelContextPerClass

        public final boolean isCreateCamelContextPerClass()
        Tells whether CamelContext should be setup per test or per class.

        By default it will be setup/teardown per test method. This method returns true when the camel test class is annotated with @TestInstance(TestInstance.Lifecycle.PER_CLASS).

        Important: Use this with care as the CamelContext will carry over state from previous tests, such as endpoints, components etc. So you cannot use this in all your tests.

        Setting up CamelContext uses the doPreSetup(), doSetUp(), and doPostSetup() methods in that given order.

        Returns:
        true per class, false per test.

      • isMockEndpoints

        public String isMockEndpoints()
        Override to enable auto mocking endpoints based on the pattern.

      • isMockEndpointsAndSkip

        public String isMockEndpointsAndSkip()
        Override to enable auto mocking endpoints based on the pattern, and skip sending to original endpoint.

        Return * to mock all endpoints.

        See Also:
        EndpointHelper.matchEndpoint(CamelContext, String, String)

      • replaceRouteFromWith

        public void replaceRouteFromWith​(String routeId,
                                 String fromEndpoint)

      • getRouteFilterIncludePattern

        public String getRouteFilterIncludePattern()
        Used for filtering routes matching the given pattern, which follows the following rules:

        - Match by route id - Match by route input endpoint uri

        The matching is using exact match, by wildcard and regular expression.

        For example to only include routes which starts with foo in their route id's, use: include=foo* And to exclude routes which starts from JMS endpoints, use: exclude=jms:*

        Multiple patterns can be separated by comma, for example to exclude both foo and bar routes, use: exclude=foo*,bar*

        Exclude takes precedence over include.

      • getRouteFilterExcludePattern

        public String getRouteFilterExcludePattern()
        Used for filtering routes matching the given pattern, which follows the following rules:

        The matching is using exact match, by wildcard and regular expression.

        For example to only include routes which starts with foo in their route id's, use: include=foo* And to exclude routes which starts from JMS endpoints, use: exclude=jms:*
