A coverage tool such as this one can be very helpful in debugging, as it is in testing.

There's no reason we have to actually have the if expression.

like the hashing and the cookies and salting and all that stuff, you can just write functions to test that there's a whole course.

An open automated test by definition reproduces the problem.

Because our JavaScript interpreter could potentially accept an infinite number of inputs there are an infinite number of possible JavaScript programs out there we don't have time to test them all.

Statistic one, lecture six, another example.

You can watch the answer hopefully you'll understand the answer and then maybe you'll be able to try it on your own again after you've seen the answer.

I just make up this tuple, number , followed by the actual value. and that's how we got things like this for ( number , 11).

Testing can never demonstrate the. Absence of air is only there. Presence, right?

I need you to pass a test.

You might want to memorize it if you just want to be able to do the test a little bit faster.

They built it.

When can we test it?

We could write down any work of literature and have it be a web page.

Once this penicillin concentrates, we can test it on the rat.

When all test are successful, we print out done.

If you make no mistake, then you get exactly the same area as you had before, and you can test your routine and arbitrary maps and arbitrary data sets, and it'll just be fine.

Elementary, my dear Watson.

If you have assertions in your code, not only can you detect errors much more easily but you can also test your code much more thoroughly.

Have you ever cheated on an exam?

If you had some additional conditions, you could test it.

So now that we understand all of that, it's a QUlZ!

Here, I'm just going to talk about how we test Dylan.

And you can also use this to fill out form fields with default values, if you know what the user is probably going to enter.

The new value of i will be ten, if we do anything here that uses the value of i we'll see that the value of i is ten

Otherwise we continue on and we set a size and a current test, best size and best test to be the length of the current test and test itself.

We could return second right away, and so now we only have 2 lines, and we'll run the same test just to show that it still works.

He could swim fast enough to pass the test.

But after this, you could have more lower case letters, more upper case letters or underscores and you can have as many of those as you want.

So we're not going to test them all in finite time we're only going to gain confidence by testing a few.

Tests database connection. You can ensure that valid connection information is provided.

Yeah. It also makes it much easier to do, for example, binary search.

We see it fails, which is not much of a surprise because 3 and 6 are both in here.

Excessive motion or soft endpoint is a positive test.

But the point remains is that the document.write function is really how you modify on a basic level the overwriting HTML page.

We'll call print_all_links with our test string that has test 1, test 2, and test 3 as the 3 links.

This first one, part of testing a program feature is running the program in a way that exercises that feature, that was the last quiz.

Education shouldn't be aimed at passing a test.

And part of the problem is, I think, that the dominant culture of education has come to focus on not teaching and learning, but testing.

What that did is registered my user, I did the whole password hashing salting thing.

This is the IP address which should be tested.

To do so, I assume that half of the people are of type A and half of the people are of type B.

That would give me all of the links sorted descending by votes with no constraints whatsoever.

Therefore, this condition is data dependent on this initialization.

We assume, there's none and if there would be one, then the assertion would immediately fail.
