Appendix A. TestRunner Details
How do we run tests? We could run our tests in the host Eclipse directly. While this is simple, it has the drawback that side effects of a test can impact the development environment. Consider a test that gets out of control and consumes all CPU cycles. You would have to shutdown your host Eclipse to recover, just because of a test. Moreover, running tests inside the host Eclipse instance makes it difficult to debug test failures.
Therefore, we want to execute the tests in a separate virtual machine. Figure A.1 illustrates the setup. Our contributed JUnit plug-in contains a test runner that launches a SocketTestRunner in a separate VM to execute the tests. The SocketTestRunner reports the results back via a socket ...
