Allow --test against a glob pattern of directories

[JoshuaKGoldberg]

Instead of yarn test:rules to run them all, or manually modifying ruleTestRunner.js to change what's running, it'd be nice to quickly run yarn test:rules -- no-floating-promises/*.

It could be done pretty easily in ruleTestRunner.ts with:

// Abridged for ease of reading
const paths = process.argv[2] || "**";
glob.sync(`test/rules/${paths}/tslint.json`)

You can use tslint CLI to test a specific rule. See --test flag in help. If you are making changes to tslint itself, you can compile and use the new compiled CLI

making changes to tslint

@mohsen1 yes, that's what I'm doing now. I'd like to sporadically run test:rules on specific .lint files without having to recompile the CLI.

To be a little more elaborate - --test only runs against one directory.

C:\Code\tslint>tslint --test test/rules/no-floating-promises/**
C:\Code\tslint\lib\configuration.js:114
            throw new Error("Could not find config file at: " + path.resolve(suppliedConfigFilePath));
            ^

Error: Could not find config file at: C:\Code\tslint\test\rules\no-floating-promises\**\tslint.json

It would be nice to have a little more control and be able to test multiple directories. Perhaps letting --test run against multiple directories would accomplish the same thing...

I have a slight preference for --test that works against more than 1 directory

That makes sense, they're basically the same. Updated the title.
