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).

Of both "--quiet" and "--format" are set, --quiet takes precedence. This
patch adds a warning to inform the user that their custom format is not
used:
docker ps --format='{{.Image}}'
ubuntu:22.04
alpine
docker ps --format='{{.Image}}' --quiet
WARNING: Ignoring custom format, because both --format and --quiet are set.
40111f61d5c5

The warning is printed on STDERR, so can be redirected:
docker ps --format='{{.Image}}' --quiet 2> /dev/null
40111f61d5c5
482efdf39fac
The warning is only shown if the format is set using the "--format" option.
No warning is shown if a custom format is set through the CLI configuration
file:
mkdir -p ~/.docker/

Previously, the formatter would ignore the quiet option if a custom format
was passed; this situation was handled in runPs(), where custom formats
would only be applied if the quiet option was not set, but only if the
format was set in the CLI's config.
This patch updates NewContainerFormat() to do the same, even if a `--format`
was passed on the command-line.
This is a change in behavior, so may need some discussion; possible alternatives;
- produce an error if both `--format` and `--quiet` are passed
- print a warning if both are passed (but use the logic from this patch)
Before this patch:
```console
docker ps --format '{{.Image}}'
ubuntu:22.04
alpine
docker ps --format '{{.Image}}' --quiet
ubuntu:22.04
alpine
mkdir -p ~/.docker/
echo '{"psFormat": "{{.Image}}"}' > ~/.docker/config.json
docker ps
ubuntu:22.04
alpine
docker ps --quiet
ubuntu:22.04
alpine
```
With this patch applied:
```console
docker ps --format '{{.Image}}'
ubuntu:22.04
alpine
docker ps --format '{{.Image}}' --quiet

- do an early check if a custom format is specified either through the
command-line, or through the cli's configuration, before adjusting
the options (to add "size" if needed).
- also removes a redundant `options.Size = opts.size` line, as this value is
already copied at the start of buildContainerListOptions()
- Update NewContainerFormat to use "table" format as a default if no format
was given.

Before this patch, using a template that used templating functions (such as
`lower` or `json`) caused the command to fail in the pre-processor step (in
`buildContainerListOptions`):
docker ps --format='{{upper .Names}}'
template: :1:8: executing "" at <.Names>: invalid value; expected string
This problem was due to the pre-processing using a different "context" type than
was used in the actual template, and custom functions to not be defined when
instantiating the Go template.
With this patch, using functions in templates works correctly:
docker ps --format='{{upper .Names}}'

Move the remaining test with the others, and rename it from
`TestBuildContainerListOptions` to `TestContainerListBuildContainerListOptions`,
so that it has the same prefix as the other tests.
