Just remove test_ez_setup, as the last remaining test, test_install, only barely touches the functionality as the actually installation command is mocked. The test run in the travis config is much more comprehensive.

Remove test for use_setuptools, as it fails when running under pytest because the installed version of setuptools is already present.

Remove test_build_egg. The test doesn't work and it's difficult to test _build_egg given the current interface.

Use a context manager instead of calling _test.run in multiple places. Alleviates need to warn about Exceptions
