Disable Jasmine's fdescribe() and fit() based on environment

Edit 14.11.19:

To make things easier I created an installable package you can find at https://www.npmjs.com/package/tslint-jasmine

Original post:

If you're using TSLint and (like me) found that all the defocus and tslint-jasmine-noSkipOrFocus checkers are not working for you, I created a Gist for that: https://gist.github.com/djungowski/7d9126bb79970446b4ffeb5656c6bf1f

How to use:

1. Save Gist in a a folder called TSLint/Rules as noJasmineFocusRule.js
2. Add the Rules folder to your TSLint config: rulesDirectory: 'TSLint/Rules'
3. Enable option with "no-jasmine-focus": true

Using something like no-focused-tests would be okay. Any idea how to enable this rule as an error in Codeship and disable it locally?

You could use a combination of environment variables and redefining the fdescribe/fit global functions:

1. npm i --save cross-env

2. package.json:

   "scripts": {
     "test": "jasmine",
     "test-safe": "cross-env FOCUSED_TESTS=off jasmine"
   },
   

3. disableFocusedTestsIfNecessary.js (included after jasmine defines its globals):

   if (process.env.FOCUSED_TESTS === "off") {
     console.log("Focused tests must be off");
     global.fdescribe = global.fit = function() {
       throw new Error("fdescribe and fit are disabled in this environment");
     };
   }
   else {
     console.log("Focused tests enabled");
   }
   

4. Tell codeship to run npm run test-safe instead of npm run test

For those interested, if you are using jasmine and eslint, you can use this plugin to ensure no focused tests: https://github.com/tlvince/eslint-plugin-jasmine.

1. First install eslint globally npm install -g eslint.
2. Then install the eslint-plugin-jasmine library npm install --save-dev eslint-plugin-jasmine.

3. Create a .eslintrc file which would look something like this:

   {
     "rules": {
       "semi": 2
     },
     "plugins": ["jasmine"],
     "env": {
       "jasmine": true
     },
     "extends": "plugin:jasmine/recommended",
   }
   

4. Then you are ready to run the linter eslint -c ./.eslintrc app.js
