Why do we need tests to be understandable by any human. IMO tests that go to that degree do so by obscuring what logic is actually running and make it harder as a developer to fully understand what is going on. I would rather just keep tests plain and simple with as few abstractions around them as possible.
Cypress cy.get(‘h1’).contains(‘Result’)
Playwright await expect(page.getByTitle(‘Result’)).toHaveCount(1)
Testing library expect(screen.getByTitle(/Result/i)).toBeTruthy()
We can nit pick about syntax here and I prefer the cypress one as it immediately tells me what it is doing and I am not even familiar with those frameworks but:
UUV Then I should see a title named “Result”
That tells me nothing about what it is actually doing. How is the framework meant to interpret that or similar things? It is imprecise and I have no way to validate it will do what I expect it should. I do not trust AI or LLMs enough to translate that into a workable test. Even if it works for simple situations like this how does it grow to far more real and complex test cases?
It would be one thing to use a LLM to generate a test for you that you can inspect - but to generate it probably on every run quite likely without being able to see what it did? Um No thanks. Not with the current state of LLMs.
At least I assume it is LLM based as there is no other way to do this as far as I am aware, though they dont seem to mention it at all.
Can when the specific situations are reached in very micro benchmark situations. But overall on aggregate you find even JIT languages don’t strictly outperform pre compiled languages for general workflows when looking at languages of a similar class. When you compare them to compiled languages like C/C++/rust/zip (aka ones without a GC or much of a runtime at all) then JIT languages fall behind like all other GCed languages.
Of these 25 reasons, most apply to a lot of languages and are far from Java exclusive or even java strong points. Pick any mainstream language and you will hit most of the benefits it lists here. With quite a few being almost meaningless. Like this:
Java/JVM/JIT can achieve runtime optimization on frequently run code, especially on something that’s running as a service so that you avoid the overheads from JVM startup times.
Compiled languages generally don’t need a JIT or to be optimized at runtime as they are compiled and optimized at compile time. And most language that don’t have a runtime like Javas already run faster than Java without its heavy startup time. Language with JITs are generally interpreted languages which have these same benefits as java lists here. Though do often suffer from other performance issues. But really at the end of the day all that really matters is how fast the language is and how good its startup times are. Java is not ahead of the pack in either of these regards and does not do significantly better then other languages in its same class (and often still drastically sucks for startup time).
Or
Much of a company’s framework can be stable Java, with Scala or Clojure-backed business logic.
Many languages you can embed other languages inside. Nothing really special about scala or clojure here except that they work well with java. And I don’t really see this as a major benefit as most places I see dont separate their core code and business logic into different languages.
And the remaining issues that are more java specific are:
Java was one of the first mainstream GC strongly typed OOP languages. So it got its niche.
Java has been one of the main programming languages taught in colleges and universities in the last few decades.
Java’s Legacy Migration: Many banks in particular migrated legacy systems to Java in the early 2000’s when it was getting a lot of popularity and the industry was collectively in the midst of a huge OOP fever dream.
Which all paint a picture - it was popular long ago and taught in universities and lots of business pushed it when back in the day. And now it is hard to move off it.
And lastly:
Oracle
What? How is this a point? If anything this should be a massive negative.
Not exactly 25 reasons to pick java in financial enterprise.
It might. Depending on how much tension there is. Too much and it will cause the filament to slip in the extruder causing under extrusion. If you are not seeing signs of under extrusion then you are fine for now - but that might change if you change filament or anything else. I would try to lower how much tension the filament is under to avoid problems in the future. Otherwise it would be something to keep in mind if you do start seeing signs of under extrusion.
Did you read the article at all?
“Putting all new code aside, fortunately, neither this document nor the U.S. government is calling for an immediate migration from C/C++ to Rust — as but one example,” he said. “CISA’s Secure by Design document recognizes that software maintainers simply cannot migrate their code bases en masse like that.”
Companies have until January 1, 2026, to create memory safety roadmaps.
All they are asking for by that date is a roadmap for dealing with memory safety issues, not rewrite everything.
What? You can easily escape from it if there are better alternatives you can use. Pointing at one language and saying it is not easy to code like it is another language is a pointless argument. You can do that about any two languages. They all differ for good reasons and as long as you can solve similar problems in both, even if in different ways then what does it matter that you cannot do it in the same way?
You could do a lot of things. Rust had a gc and it was removed so they have already explored this area and are very unlikely to do so again unless there is a big need for it that libraries cannot solve. Which I have not seen anyone that actually uses the language a lot see the need for.
Not like how async was talked about - that required a lot if discussion and tests in libraries before it was added to the language. GC does not have anywhere near as many people pushing for it, the only noise I see is people on the outside thinking it would be nice with no details on how it might work in the language.
So someone that is not involved in rust at all and does not seem to like the language thinks it will get a GC at some point? That is not a very credible source for such a statement. Rust is very unlikely to see an official GC anytime soon if ever. There are zero signs it will ever get one. There was a lot of serious talk about it before 1.0 days - but never made it into the language. Similar to green threads which was a feature of the language pre 1.0 days but dropped before the 1.0 release. Rust really wants to have a no required runtime and leans heavy on the zero-cost abstractions for things. Which a GC would impose on the language.
There are quite a few places where a GC is just not acceptable. Anything that requires precise timing for one. This includes kernel development, a lot of embedded systems, gaming, high frequency trading and even latency critical web servers. Though you are right that a lot of places a GC is fine to have. But IMO rust adds more than just fast and safe code without a GC - lots of people come to the language for those but stay for the rest of the features it has to offer.
IMO a big one is the enum support it has and how they can hold values. This opens up a lot of patterns that are just nice to use and one of the biggest things I miss when using other languages. Built with that are Options and Results which are amazing for representing missing values and errors (which is nicer than coding with exceptions IMO). And generally they whole type system leads you towards thinking about the state things can be in and accounting for those states which tends to make it easier to write software with fewer issues in production.
