Some tests will create files and directories as part of the execution path for Packer, and we need a way to check this, so this commit adds a new file gadget to do those checks after a command executes.
When trying to validate that a particular file exists after a run of Packer in a test suite, we can use the FileExists checker that we provide as part of the gadgets we added for the acceptance test suites. This approach works well, but only if we can extract a file name reliably from the output of Packer core, or if we know what to look for exactly beforehand. For other cases with a generated name however, the FileExists checker is not enough, and therefore to accomodate for those cases, we are introducing a new checker for this purpose: FileGlob. FileGlob, as its name suggests, runs a glob expression on the filesystem, and returns an error if no match was found regarding this glob expression.

Yep, the plan is to have those merged already, so we don't have a dependency problem when/if we revisit those, as that code will already have been merged into main! Thanks for the approval, merging this now! |
