Astra is also more likely to operate within the boundaries set by the user and implied by its environment. In an internal evaluation, Astra never attempted to circumvent a Codex Auto-Review denial.

Astra causes fewer misaligned outcomes than any other frontier models tested. For a fair comparison, we used a generic computer-using-agent harness...

One of the great problems in the social sciences is that theories regularly develop in ways that make it difficult to test them empirically;34

The company said that in testing, 95 percent of Fable sessions ran entirely on Fable responses, without falling back to Opus 4.8.

safety concerns

When Claude Opus 4.6 and Mythos Preview were undergoing safety testing, NLAs suggested they believed they were being tested more often than they let on.

So I realized what I value more than the quality of the tests and documentation is that I want somebody to have _used_ the thing.

After multiple weeks of internal testing and no regressions in the set of evaluations we ran, we felt confident about the change and shipped it alongside Opus 4.7 on April 16.

Two unrelated experiments made it challenging for us to reproduce the issue at first: an internal-only server-side experiment related to message queuing; and an orthogonal change in how we display thinking suppressed this bug in most CLI sessions

In our internal evals and testing, medium effort achieved slightly lower intelligence with significantly less latency for the majority of tasks.

Begin with fast checks that explain behavior, then add slower, heavier checks only when they reduce risk.

A common piece of advice for working with AI coding tools is to simply write more tests because if the tests pass, the code is fine.

but would fail recognize that the feature didn't work end-to-end

This class of bug is insidious because it evades every layer of defense. It will not be caught in development testing — who runs a test for 50 days? It will not be flagged in code review — the logic looks perfectly reasonable.

a clockwork watch may be ticking normally, such that it’s very hard to tell that it is likely to break down next month, but opening up the watch and looking inside can reveal mechanical weaknesses that allow you to figure it out.

Those who boast of such high cognition should not keep it backbut should present it publicly to be tested and esteemed.

When writing component tests that involve two-way bindings, context or snippet props, it’s best to create a wrapper component for your specific test and interact with that. @testing-library/svelte contains some examples.

Vitest makes writing tests directly within your source code easy, eliminating the need for separate test files. This approach, known as in-source testing, is useful when you want to quickly test individual functions without the overhead of creating and managing separate test files.

Interact with live systems whenever feasible instead of mocking components to uncover potential integration issues.

Today I realized that the pursuit of knowledge is a lifelong journey. It’s important to question what we know to avoid biases.

Enhances ActionMailer to support the :cache delivery method, which behaves like :test, except that the deliveries are marshalled to a temporary cache file, thus making them available to other processes.

There are two things that I enjoy: a test framework written in my own Domain Specific Language (DSL) that is easily understood by all those on a project and the ability for all participants to easily read, search, and view the tests.

Disable all observers in your test suite by default. They should not be complicating your model tests because they should have separate concerns anyway. You don't need to unit test that observers actually fire, because ActiveRecord's test suite does that, and your integration tests will cover it.

I emphatically disagree with BlueFish about observers being difficult to properly unit test. This is precisely the biggest point that distinguishes them from lifecycle callbacks: you can test observers in isolation, and doing so discourages you from falling into many of the state- and order-heavy design pitfalls BlueFish refers to (which again I think is more often true of lifecycle callbacks).

flip to the acknowledgments in cookbooks to see if testers are thanked.

This is the most simulative version of a controller. It will try and mimic real user behaviour. It's the recommended version to use when the goal of the load-test is finding out how many concurrently active users the target instance supports.

As of right now the full build takes over an hour to run, and this makes cycling for PRs and quick iterative development very difficult.

He pointed out that these questions penalize the more imaginative and favor those who are content to collect facts. Therefore, multiple-choice test statistics, in all their uses, are misleading.

Thirty years ago, the physicist and teacher Banesh Hoffmann wrote a book, ''The Tyranny of Testing,'' which was attacked by the test-making industry and ignored by educationists. It showed how multiple-choice questions, by their form and substance, work against the aim of teaching.

Youmust apprehend the unity with definiteness. There is only oneway to know that you have succeeded. You must be able totell yourself or anybody else what the unity is, and in a fewwords. ( If it requires too many words, you have not seen theunity but a multiplicity. ) Do not be satisfied with "feeling theunity" that you cannot express. The reader who says, "I knowwhat it is, but I just can't say it," probably does not even foolhimself.

I ran into the same problem and never really found a good answer via the test objects. The only solution I saw was to actually update the session via a controller. I defined a new action in one of my controllers from within test_helper (so the action does not exist when actually runnning the application). I also had to create an entry in routes. Maybe there’s a better way to update routes while testing. So from my integration test I can do the following and verfiy: assert(session[:fake].nil?, “starts empty”) v = ‘Yuck’ get ‘/user_session’, :fake => v assert_equal(v, session[:fake], “value was set”)

we should have some psychological screening at the top jobs. I think that there should be an expectation that people who are about to control nuclear weapons, that can literally wipe out our species, should, at a minimum, be subject to a psychological test.

REPLs are nice but they work well only for reasonably isolated code with few dependencies. It's hard to set up a complex object to pass into a function. It's harder still to set up an elaborate context of dependencies around that function.

Industrial concerns doubtless suffer enormous losses from the employment of persons whose mental ability is not equal to the tasks they are expected to perform. The present methods of trying out new employees, transferring them to simpler and simpler jobs as their inefficiency becomes apparent, is wasteful and to a great extent unnecessary. A cheaper and more satisfactory method would be to employ a psychologist to examine applicants for positions and to weed out the unfit. Any business employing as many as five hundred or a thousand workers, as, for example, a large department store, could save in this way several times the salary of a well-trained psychologist.

Nonparametric statistics are often preferred to parametric tests when the sample size is small and the data are skewed or contain outliers.

Our test raises an ActiveRecord::RecordNotFound exception. We know that Rails has special handling to return a 404 status code in this case. However, the request spec still raises the exception.

What we ultimately should care about is being able to use our knowledge to produce something new, whatever that may be. To not merely reproduce you must understand the material. And understanding requires application, a hermeneutic principle that particularly Gadamer worked out extensively. If you really want to measure your level of understanding, you should try to apply or explain something to yourself or someone else.
