test(derive): Provide better error info `Parser::parse_from` will call `exit` on failure and we don't just lose backtrace information but we don't even know which of the tests running in parallel panicked. I ran into this when experimenting with `clap_derive` and I couldn't tell what actually failed. So let's switch to `Parse::try_parse_from`. Errors went from: ``` test option_option ... ok error: Found argument 'bar' which wasn't expected, or isn't valid in this context USAGE: clap_derive [OPTIONS] For more information try --help error: test failed, to rerun pass '--test arg_enum' ``` To: ``` test option_option ... ok test variant_with_defined_casing ... ok test skip_variant ... ok test default_value ... ok test vector ... FAILED test option_vector ... ok failures: ---- vector stdout ---- thread 'vector' panicked at 'called `Result::unwrap()` on an `Err` value: Error { message: Formatted(Colorizer { use_stderr: true, color_when: Auto , pieces: [("error:", Some(Red)), (" ", None), ("Found argument '", None), ("bar", Some(Yellow)), ("' which wasn't expected, or isn't valid in this context", None), ("\n\n", None), ("USAGE:\n clap_derive [OPTIONS]", None), ("\n\nFor more information try ", None), ("--help", Some(Green)), (" \n", None)] }), kind: UnknownArgument, info: ["bar"], source: None, backtrace: Backtrace }', clap_derive/tests/arg_enum.rs:388:56 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace failures: vector test result: FAILED. 15 passed; 1 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.00s error: test failed, to rerun pass '--test arg_enum' ```

test(derive): Provide better error info `Parser::parse_from` will call `exit` on failure and we don't just lose backtrace information but we don't even know which of the tests running in parallel panicked.

test(derive): Provide better error info `Parser::parse_from` will call `exit` on failure and we don't just lose backtrace information but we don't even know which of the tests running in parallel panicked. I ran into this when experimenting with `clap_derive` and I couldn't tell what actually failed. So let's switch to `Parse::try_parse_from`. Errors went from: ``` test option_option ... ok error: Found argument 'bar' which wasn't expected, or isn't valid in this context USAGE: clap_derive [OPTIONS] For more information try --help error: test failed, to rerun pass '--test arg_enum' ``` To: ``` test option_option ... ok test variant_with_defined_casing ... ok test skip_variant ... ok test default_value ... ok test vector ... FAILED test option_vector ... ok failures: ---- vector stdout ---- thread 'vector' panicked at 'called `Result::unwrap()` on an `Err` value: Error { message: Formatted(Colorizer { use_stderr: true, color_when: Auto , pieces: [("error:", Some(Red)), (" ", None), ("Found argument '", None), ("bar", Some(Yellow)), ("' which wasn't expected, or isn't valid in this context", None), ("\n\n", None), ("USAGE:\n clap_derive [OPTIONS]", None), ("\n\nFor more information try ", None), ("--help", Some(Green)), (" \n", None)] }), kind: UnknownArgument, info: ["bar"], source: None, backtrace: Backtrace }', clap_derive/tests/arg_enum.rs:388:56 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace failures: vector test result: FAILED. 15 passed; 1 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.00s error: test failed, to rerun pass '--test arg_enum' ```
