JS/TS default rules

[elado]

this is what I use:

    "findrelated.applyRulesets": [
        "js"
    ],
    "findrelated.rulesets": [
        {
            "name": "js",
            "rules": [
                {
                    "pattern": "(.+)\/([^\/]+?)\\.([tj]sx?)$",
                    "locators": [
                        "$1\/{tests,__tests__,__test__}/$2.spec.$3"
                    ]
                },
                {
                    "pattern": "(.+)\/(?:tests|__tests__|__test__)\/([^\/]+?)\\.spec\\.([tj]sx?)$",
                    "locators": [
                        "$1\/$2.$3"
                    ]
                }
            ]
        }
    ],

works for my projects, can probably be improved, but a good start.

@elado why the tests,__tests__,__test__ to handle differently named test folders?

yeah, they cover different common patterns for the defaults used by javascript test runners (i typically use ava and jest).

I modified the rules to:

"rules": [
      {
        "pattern": "(.+)\/([^\/]+?)\\.([tj]sx?)$",
        "locators": [
          "$1/{test,tests,__tests__,__test__}/$2{.spec,.test,}.$3"
        ]
      },
      {
        "pattern": "src/(.+)\/([^\/]+?)\\.([tj]sx?)$",
        "locators": [
          "src/$1/{test,tests,__tests__,__test__}/$2{.spec,.test,}.$3",
          "{test,tests,__tests__,__test__}/$1/$2{.spec,.test,}.$3",
        ]
      },
      {
        "pattern": "(.+)\/(?:tests?|__tests?__)\/((?:.+?/)?(?:[^\/]+?))(?:\\.spec|\\.test)?\\.([tj]sx?)$",
        "locators": [
          "$1/$2.$3",
          "src/$1/$2.$3"
        ]
      },
      {
        "pattern": "(?:tests?|__tests?__)\/((?:.+?/)?(?:[^\/]+?))(?:\\.spec|\\.test)?\\.([tj]sx?)$",
        "locators": [
          "$1.$2",
          "src/$1.$2"
        ]
      }
    ]

This new ruleset should also handle the common pattern of including spec files in the same directory as the code under test. This is pattern is widely followed in the Angular community (see here for an example).

I'm using the following ruleset for javascript files in my Angular projects:

{
  "name": "javascript",
  "rules": [
    {
      "pattern": "(.*)\\.spec\\.([tj]sx?)$",
      "locators": [
        "$1.$2",
      ]
    },
    {
      "pattern": "(.*)\\.([tj]sx?)$",
      "locators": [
        "$1.spec.$2",
      ]
    }
  ]
}

Also I'm no regex wizard but the patterns mentioned before look like they might be more complicated than they need to be.
