Hi, tl;dr Are there any existing end-to-end testing libraries for CLI applications? Specifically, what I'm looking for is a library that makes it easy to test that "running this command should produce this output" without fear that a buggy application could corrupt the filesystem.
Background: I have a few CLI applications (written in Go) that are becoming quite complex. I'd like to add some end-to-end and integration tests to ensure that I don't accidentally break existing functionality while refactoring or adding new features. The CLI applications can make arbitrary changes to the filesystem and I don't want it to be possible for a buggy application to leave any trace on the filesystem after the test terminates. I want something like: - Easy setup of a chroot environment or Docker container or similar with my Go binary copied somewhere into $PATH. - Easy way to specify what commands should be run. - Easy way to write tests that check exit codes and ensure that the stdout/stderr output matches a string or regular expression. - Automatic tidy-up of the chroot/container after the test is complete. - Scripted in Go and integrated with Go's testing package, of course :) I don't need controls over CPU usage or networking as my applications are not CPU bound and do not need network access, but I wouldn't complain if they existed. A hypothetical test would look something like: https://play.golang.org/p/7L6PZIjvyy6. I know about github.com/ory/dockertest which is fantastic for writing integration tests with third-party services but not set up for testing your own applications. Do you know of any existing libraries that implement this sort of functionality? Many thanks, Tom -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
