When running tests from my IDE, it compiles the tests before running, then executes the compiled binary to run the tests. Cobra doesn't like that, because in that situation os.Args is taken as argument for the command that's executed. The command that's tested now sees the
test-
flags as arguments (-test.v -test.run ..
), which causes various tests to fail ("Command XYZ does not accept arguments").Set arguments to an empty slice to make sure it doesn't inherit arguments from the test-binary.
