All Implemented Interfaces:
org.junit.runner.Describable, org.junit.runner.manipulation.Filterable, org.junit.runner.manipulation.Orderable, org.junit.runner.manipulation.Sortable
Direct Known Subclasses:

Enclosing class:
SandboxTestRunner
protected static class SandboxTestRunner.HelperTestRunner extends org.junit.runners.BlockJUnit4ClassRunner
The goal of SandboxTestRunner.HelperTestRunner is to have BlockJUnit4ClassRunner instances that encapsulate bootstrapped test classes. When SandboxTestRunner is initially constructed, the test class is from the main app class loader. This test class can't be used to run tests because it can't load Android classes.

Because we need load a separate test class per sandbox, we need to create a new Runner that encapsulates the bootstrapped test class. This is primarily used to invoke the ParentRunner#methodBlock(FrameworkMethod), which uses reflection to invoke before/after methods and test rules.

    • methodInvoker

      protected org.junit.runners.model.Statement methodInvoker(org.junit.runners.model.FrameworkMethod method, Object test)
      For tests with a timeout, we need to wrap the test method execution (but not @Befores or @Afters in a TimeLimitedStatement. JUnit's built-in FailOnTimeout statement causes the test method (but not @Befores or @Afters) to be run on a short-lived thread. This is inadequate for our purposes; we want to guarantee that every entry point to test code is run from the same thread.
      Overrides:
      methodInvoker in class org.junit.runners.BlockJUnit4ClassRunner

      protected org.junit.runners.model.Statement withPotentialTimeout(org.junit.runners.model.FrameworkMethod method, Object test, org.junit.runners.model.Statement next)
      Disables JUnit's normal timeout mode strategy.
