When running tests in verbose mode (or other options), tests involving Cobra may fail if the test does not explicitly set Command.args to an empty slice; in this case, Cobra defaults to using `os.Args`, which will contain arguments passed to the test (such as `-v` (verbose)). Commitse5762054c9and1ef0913976implemented a workaround for this when running (unit) tests for Cobra itself, but this check is specifig to Cobra (checking for `cobra.test`), and don't work on Windows (which will have a `.exe` extension), This patch implements a more universal check, so that users of Cobra as a module also benefit from this workaround. go1.21 and up provides a `testing.Testing()` utility ([1]); as the Cobra module still supports Go1.16 and up, an alternative implementation was added for older versions, based on golang.org/x/mod/lazyregexp [2].
