Linting is about so much more than code style and standards. Since we use auto format I have almost all the style checks off. What it does catch is hundreds of different types of potential bugs. Uninitialized variable. Missing null check. Deprecated or beta marked api used. Improper thread synchronization and double locking. Reassignment of parameters. Conditional check that's always true/false. This list is huge, and in my experience it catches mistakes constantly. For the average crud app, if you're wrong about the requirements the tests will be wrong anyways. It sounds like you're talking more about TDD which IMO is a cargo cult. And I'm hardly the only one with that opinion. Integration tests are important but that's more about running data through the code all at once than testing each function in isolation. Also, many open source projects get along with hardly any tests. The Linux kernel is probably the best example, but there's tons of popular projects without good or any tests. Check NPM popular repositories, I'll bet you more than half of the top 500 are under 10% code coverage. Tons of huge apps are doing fine without tests, and many I've worked on with tests are still horrible. I haven't really noticed any contribution from having lots of tests. IMO what's far more important is linting and maintaining code standards. It's hard to write a function that's horrible to debug when the linter limits you to 300 lines. Or a class that's totally incomprehensibly long when the linter limits you to 1000. All of my debugging nightmare projects have been due to lack of sound OOP principles, huge files of spaghetti. Good linting prevents that from happening. Besides Java my other big language is TypeScript. Using Mockito in java isn't that bad, and JUnit5 or TestNg are decent. Certainly easier than getting tests working in the garbage fire that is Angular6 + Jasmine + Karma.
