This makes a quick pass through our tests;

Discard output/err
----------------------------------------------

Many tests were testing for error-conditions, but didn't discard output.
This produced a lot of noise when running the tests, and made it hard
to discover if there were actual failures, or if the output was expected.
For example:

    === RUN   TestConfigCreateErrors
    Error: "create" requires exactly 2 arguments.
    See 'create --help'.

    Usage:  create [OPTIONS] CONFIG file|- [flags]

    Create a config from a file or STDIN
    Error: "create" requires exactly 2 arguments.
    See 'create --help'.

    Usage:  create [OPTIONS] CONFIG file|- [flags]

    Create a config from a file or STDIN
    Error: error creating config
    --- PASS: TestConfigCreateErrors (0.00s)

And after discarding output:

    === RUN   TestConfigCreateErrors
    --- PASS: TestConfigCreateErrors (0.00s)

Use sub-tests where possible
----------------------------------------------

Some tests were already set-up to use test-tables, and even had a usable
name (or in some cases "error" to check for). Change them to actual sub-
tests. Same test as above, but now with sub-tests and output discarded:

    === RUN   TestConfigCreateErrors
    === RUN   TestConfigCreateErrors/requires_exactly_2_arguments
    === RUN   TestConfigCreateErrors/requires_exactly_2_arguments#01
    === RUN   TestConfigCreateErrors/error_creating_config
    --- PASS: TestConfigCreateErrors (0.00s)
        --- PASS: TestConfigCreateErrors/requires_exactly_2_arguments (0.00s)
        --- PASS: TestConfigCreateErrors/requires_exactly_2_arguments#01 (0.00s)
        --- PASS: TestConfigCreateErrors/error_creating_config (0.00s)
    PASS

It's not perfect in all cases (in the above, there's duplicate "expected"
errors, but Go conveniently adds "#01" for the duplicate). There's probably
also various tests I missed that could still use the same changes applied;
we can improve these in follow-ups.

Set cmd.Args to prevent test-failures
----------------------------------------------

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").

    # compile the tests:
    go test -c -o foo.test

    # execute the test:
    ./foo.test -test.v -test.run TestFoo
    === RUN   TestFoo
    Error: "foo" accepts no arguments.

The Cobra maintainers ran into the same situation, and for their own
use have added a special case to ignore `os.Args` in these cases;
https://github.com/spf13/cobra/blob/v1.8.1/command.go#L1078-L1083

    args := c.args

    // Workaround FAIL with "go test -v" or "cobra.test -test.v", see #155
    if c.args == nil && filepath.Base(os.Args[0]) != "cobra.test" {
        args = os.Args[1:]
    }

Unfortunately, that exception is too specific (only checks for `cobra.test`),
so doesn't automatically fix the issue for other test-binaries. They did
provide a `cmd.SetArgs()` utility for this purpose
https://github.com/spf13/cobra/blob/v1.8.1/command.go#L276-L280

    // SetArgs sets arguments for the command. It is set to os.Args[1:] by default, if desired, can be overridden
    // particularly useful when testing.
    func (c *Command) SetArgs(a []string) {
        c.args = a
    }

And the fix is to explicitly set the command's args to an empty slice to
prevent Cobra from falling back to using `os.Args[1:]` as arguments.

    cmd := newSomeThingCommand()
    cmd.SetArgs([]string{})

Some tests already take this issue into account, and I updated some tests
for this, but there's likely many other ones that can use the same treatment.

Perhaps the Cobra maintainers would accept a contribution to make their
condition less specific and to look for binaries ending with a `.test`
suffix (which is what compiled binaries usually are named as).
