Package io.split.client.testing.runner

Class SplitTestRunner

  • All Implemented Interfaces:
    org.junit.runner.Describable, org.junit.runner.manipulation.Filterable, org.junit.runner.manipulation.Orderable, org.junit.runner.manipulation.Sortable
    public class SplitTestRunner
extends org.junit.runners.BlockJUnit4ClassRunner
    Split Test Runner

    Extension of standard JUnit 4 Runner Leverages Split* Testing Annotations to automate unit testing across various Feature Flag treatments Only one Annotation is respected per Test (IE Can not combine @SplitTest with @SplitScenarios on a single Test method)

        public SplitTestRunner​(Class<?> klass)
                throws org.junit.runners.model.InitializationError
        Split Test Runner Constructor

        Runner is instantiated by using the @RunWith(SplitTestRunner.class) annotation. Not to be called directly.

        Parameters:
        klass - The Test class to be run
        Throws:
        org.junit.runners.model.InitializationError - Error occurred during class initialization

    • Method Detail

      • computeTestMethods

        protected List<org.junit.runners.model.FrameworkMethod> computeTestMethods()
        Run tests in Alphabetical Order

        Runner is instantiated by using the @RunWith(SplitTestRunner.class) annotation. Not to be called directly.

        Overrides:
        computeTestMethods in class org.junit.runners.BlockJUnit4ClassRunner

      • runChild

        protected void runChild​(org.junit.runners.model.FrameworkMethod method,
                        org.junit.runner.notification.RunNotifier notifier)
        Run Suite of Scenarios for a Test

        Generates a Suite of Scenarios and then runs the test once for each permutation. If no Scenarios are defined, or the only defined Scenario has no Tests set, Run test normally

        Overrides:
        runChild in class org.junit.runners.BlockJUnit4ClassRunner
        Parameters:
        method - The Test function to be run
        notifier - The notifier class tracking test execution

      • withBefores

        protected org.junit.runners.model.Statement withBefores​(org.junit.runners.model.FrameworkMethod method,
                                                        Object target,
                                                        org.junit.runners.model.Statement statement)
        Adds Split Application to the Test's Call Stack

        This Override method first adds the application of Splits to run before the test execution. Then calls the SuperClass's method to add all @Before annotations to the call stack

        This is required to ensure the Tested code is using the same SplitClient that the Runner is using.

        Overrides:
        withBefores in class org.junit.runners.BlockJUnit4ClassRunner
        Returns:
        An instance of the Test Class being run

      • generateSuite

        public Suite generateSuite​(org.junit.runners.model.FrameworkMethod method)

      • describeChild

        protected org.junit.runner.Description describeChild​(org.junit.runners.model.FrameworkMethod method)
        Generate Test Description

        If no Scenarios are on for that test, describe normally Otherwise Describe as a Suite of tests, showing the active splits for each Scenario in that run's description

        Overrides:
        describeChild in class org.junit.runners.BlockJUnit4ClassRunner
        Parameters:
        method - The Test method to be run
        Returns:
        A formatted description of that Test
