A field study at Google[4] covering over 100,000 consumer-grade drives from December 2005 to August 2006 found correlations between certain S.M.A.R.T. information and annualized failure rates: In the 60 days following the first uncorrectable error on a drive (S.M.A.R.T. attribute 0xC6 or 198) detected as a result of an offline scan, the drive was, on average, 39 times more likely to fail than a similar drive for which no such error occurred. First errors in reallocations, offline reallocations (S.M.A.R.T. attributes 0xC4 and 0x05 or 196 and 5) and probational counts (S.M.A.R.T. attribute 0xC5 or 197) were also strongly correlated to higher probabilities of failure. Conversely, little correlation was found for increased temperature and no correlation for usage level. However, the research showed that a large proportion (56%) of the failed drives failed without recording any count in the "four strong S.M.A.R.T. warnings" identified as scan errors, reallocation count, offline reallocation and probational count. Further, 36% of failed drives did so without recording any S.M.A.R.T. error at all, except the temperature, meaning that S.M.A.R.T. data alone was of limited usefulness in anticipating failures.[5]

Students require a variety of learning situations and opportunities in order to be aware of and reflect on...variation, and to be able to make fine distinctions about the significant aspects of each new context. By identifying the differences between similar situations, the student is better able to respond appropriately. Such learning experiences are an important preparation for the unpredictable nature of the workplace

A village scoring 1.5 and another scoring 1.49 would be almost equally insecure.

Then inject it inside a test by calling TestBed.get() with the service class as the argument. it('should use ValueService', () => { service = TestBed.get(ValueService); expect(service.getValue()).toBe('real value'); });

However, you almost always inject service into application classes using Angular dependency injection and you should have tests that reflect that usage pattern. Angular testing utilities make it easy to investigate how injected services behave.

We can even remove the AuthService import if we want, there really is no dependency on anything else. The LoginComponent is tested in isolation:

That’s not very isolated but also not too much to ask for in this scenario. However imagine if LoginComponent required a number of other dependencies in order to run, we would need to know the inner workings of a number of other classes just to test our LoginComponent. This results in Tight Coupling and our tests being very Brittle, i.e. likely to break easily. For example if the AuthService changed how it stored the token, from localStorage to cookies then the LoginComponent test would break since it would still be setting the token via localStorage.

Mocking localStorage is optional, but without mocking getComputedStyle your test won’t run, as Angular checks in which browser it executes. We need to fake it.

Or inside the beforeEach() if you prefer to inject the service as part of your setup. beforeEach(() => { TestBed.configureTestingModule({ providers: [ValueService] }); service = TestBed.get(ValueService); });

Something that I've found helps greatly with testing is that when you have code with lots of nested function calls you should try to refactor it into a flat, top level pipeline rather than a calling each function from inside its parent function. Luckily in clojure this is really easy to do with macros like -> and friends, and once you start embracing this approach you can enter a whole new world of transducers. What I mean by a top level pipeline is that for example instead of writing code like this: (defn remap-keys [data] ...some logic...) (defn process-data [data] (remap-keys (flatten data))) (defn get-data [] (let [data (http/get *url*)] (process-data data))) you should make each step its own pure function which receives and returns data, and join them all together at the top with a threading macro: (defn fetch-data [url] (http/get url)) (defn process-data [data] (flatten data)) (defn remap-keys [data] ...some logic...) (defn get-data [] (-> *url* fetch-data process-data remap-keys)) You code hasn't really changed, but now each function can be tested completely independently of the others, because each one is a pure data transform with no internal calls to any of your other functions. You can use the repl to run each step one at a time and in doing so also capture some mock data to use for your tests! Additionally you could make an e2e tests pipeline which runs the same code as get-data but just starts with a different URL, however I would not advise doing this in most cases, and prefer to pass it as a parameter (or at least dynamic var) when feasible.

Douglas Crockford 2018-08-24 JSCheck is a testing tool for JavaScript. It was inspired by QuickCheck, a testing tool for Haskell developed by Koen Claessen and John Hughes of Chalmers University of Technology. JSCheck is a specification-driven testing tool. From a description of the properties of a system, function, or object, it will generate random test cases attempting to disprove those properties, and then report its findings. That can be especially effective in managing the evolution of a program because it can show the conformance of new code to old code. It also provides an interesting level of self-documentation, because the executable specifications it relies on can provide a good view of the workings of a program.

Nightwatch.js is an easy to use Node.js based End-to-End (E2E) testing solution for browser based apps and websites. It uses the powerful W3C WebDriver API to perform commands and assertions on DOM elements.

Let’s think of some properties for the rectangle area function: Given any two width and height values, the result is always a multiple of the two Order doesn’t matter. A rectangle which is 50×100 has the same area as one which is 100×50 If we divide the area by width, we should get the height Here we have three examples of how we can verify the test result for any given input without having to know the inputs up front. All of these should always hold true for any given valid input.

JSVerify is a property-based testing library, highly inspired by QuickCheck. It is testing framework agnostic, you could use JSVerify with Mocha, nodeunit, Jasmine or any other framework.

From Weekend Edition on NPR. Annotations in source available here. “Robograders” are on the rise in high stakes testing, and other aspects of our classrooms. Keep in mind this is just an algorithm looking for patterns in student writing. An algorithm isn’t magic, it’s code (writing) written by people. “The idea is bananas, as far as I’m concerned,” says Kelly Henderson, an English teacher at Newton South High School just outside Boston. “An art form, a form of expression being evaluated by an algorithm is patently ridiculous.”

Except that if the written assessment is such that it can be graded accurately by software, that’s probably not very good assessment. If what’s important are the facts and key concepts, won’t multiple-choice do?

In hindsight, I read these acts as cries for help, a kind of academic self-medication. I was bored, not because I’d mastered the required material – I got more than my share of non-A grades – but because the things I was asked to do were generally uninspiring. Perhaps nothing was more uninspiring than preparing for an AP exam.

Testing and Confinement - source that utilizes globals is somewhat more difficult to test because one cannot readily set up a 'clean' environment between runs. More generally, source that utilizes global services of any sort (e.g. reading and writing files or databases) that aren't explicitly provided to that source is difficult to test for the same reason. For communicating systems, the ability to test system invariants may require running more than one 'copy' of a system simultaneously, which is greatly hindered by any use of shared services - including global memory - that are not provided for sharing as part of the test.

Testing of any kind is, however, a fundamentally limited approach to determining whether any fact about a computer system is true or untrue.

On the simplest level, some programming languages are designed to prevent certain classes of mistakes. For example, some are designed in such a way that it is impossible to make the mistake that caused the Heartbleed bug.45These techniques have also been deployed in the aviation industry, for example, to ensure that the software that provides guidance functionality on rockets, airplanes, satellites, and scientific probes does not ever crash, as software failures have caused the losses of several vehicles in the past

static methods on their own say nothing about how a program interacts with its environment

Code can be complicated or obfuscated, and even expert analysis often misses eventual problems with the behavior of the program.

WebPack developers need not call compileComponents because it inlines templates and css as part of the automated build process that precedes running the test.

You should write isolated unit tests for pipes and services.

Furthermore, the format of the test causes many educators to erroneously believe that the state test or provincial exam only assesses low-level knowledge and skill. This, too, is false. Indeed, the data from released national tests show conclusively that the students have the most difficulty with those items that require understanding and transfer, not recall or recognition.

Unfortunately, penicillin was ineffective against the rabbit's infection. Disappointed, Fleming set the drug aside for a decade, as the rabbits had "proved" the drug was useless as a systemic medication.Years later, he administered the drug in desperation to a dying patient, for whom all other treatments were ineffectual. The penicillin performed a miracle, and the rest is history.

Had Fleming himself carried out a simple and well established animal test - the mouse protection test - the potential of his discovery might have been realised 10 years earlier

students were being made to take them several times a year, including “benchmark” tests to prepare them for the other tests.

The term “testing” evokes a certain response from most of us: the person being tested is being evaluated on his or her knowledge or understanding of a particular area, and will be judged right or wrong, adequate or inadequate based on the performance given. This implicit definition does not reflect the settings in which the benefits of “test-enhanced learning” have been established.

Setting aside the last few minutes of a class to ask students to recall, articulate, and organize their memory of the content of the day’s class may provide significant benefits to their later memory of these topics.

This theory posits that memory has two components: storage strength and retrieval strength. Retrieval events improve storage strength, enhancing overall memory, and the effects are most pronounced at the point of forgetting—that is, retrieval at the point of forgetting has a greater impact on memory than repeated retrieval when retrieval strength is high.

 Imagine an educational system in which we based our understanding of student potential and achievement upon individual interests and passions, developed and nurtured throughout the years of schooling. This is what most teachers intuitively seek to do. Imagine, then, how amazing schools could be without the false conventions of examinations and tests that are philosophically at variance with all that we know about learning and humanity. Imagine the traditionalist bereft of the Examination Excuse. The fact is, we know that we don’t need examinations for students to get into good colleges and we don’t even need good colleges to learn and be successful, so why is this absurdity still the unchallenged tail that wags the dog of our school systems?

For this reason, integration tests should always be kept separate from unit tests, in order to keep the unit tests running as quickly as they can.

The basic principle is that you patch where an object is looked up, which is not necessarily the same place as where it is defined. A couple of examples will help to clarify this.
