main panics when following /dev/stdin since /dev/stdin is not seekable.
Check to see if file is seekable and use unbounded_seek if so.
Also `tail -f` with no files should not follow stdin.
Although for some tests this adds characters
we still use them there because the
brevity cost is now worth the benefit in
terms of instant, natural-language readability
and recognizability for people not familiar
with this tests of this module or even the project
Updates to individual integration tests
- use proposed conventional approach to beginning tests
- use new convenience functions for using fixtures
- use new names for TestScenario
Updates to integration test modules
- add proposed conventional module-level functions
Updates to test/common/util.rs
- rename TestSet, and its methods, for semantic clarity
- create convenience functions for use of fixtures
- delete convenience functions obsoleted by new conventions
The main motivation is to move toward running those tests for a specific
target, that is, if a test won't run on Windows, then we shouldn't build
it. This was previously the default behavior and prevented a successful
run on AppVeyor.
I borrowed this pattern from the tests in the Cargo project.
