Something very important to point out is that you are currently trying to use a Firebase callable function, as shown by the function heading functions.https.onCall(() => {});. Since you want to work with requests and response codes, the correct type of function to use is an HTTP function. You would only need to change the heading in your index.js:

What is this.root in our school's provided code

Your school's template code does not manage what is the root of the tree, so this must be managed in a variable by the driver code. In the testing code this variable is named binarySearchTree, and it really is what would be called this.root in the second (2-class) implementation.

Now, while practicing, I've seen something odd. Upon creation of a new node of an empty binary tree, the first node ends up being completely empty [...] Is this a desired behavior?

No it is not desired behavior. The template code does not provide the concept of an empty binary tree. It expects you to create the tree with at least one value, which should be provided as argument to the constructor. It is not intended to leave out the argument when calling the constructor.

The 2-class implementation provides the idea of an empty tree. But the school's template code does not; you would just have to state binarySearchTree = null if you want an empty tree. But the downside is clear: you cannot use the methods of the class to add a value to that. The only way to get the first value in a tree is to call the constructor and assign the constructed object to your binarySearchTree variable. So adding the very first value to the tree requires a different approach than adding the other values. This is also what you see in the testing code: the first value is added as argument to the constructor -- which is always called with an argument -- while the other values are added by calling the add method. This is a pity and really shows the limitations of the template code.

How can I implement the .height method in order to measure the depth of a Tree.

The idea is that you use recursion:

If there is a left child, get the height of the left subtree through recursion. If there is none, use -1 as default, as it is an empty subtree, and empty trees have a height of -1. Do the same at the right side. Get the maximum of these two values, since only the higher subtree of the two determines what is the height of the tree. Finally add one to this result so to account for the current node.

I found the cause of the breakdown. The fact is that starting from v1.15.3, TestCafe resets the cache of modules requested in test files. Because of this, getScenario sometimes tries to find a script in an object that has been overwritten.

I have fixed this bug in the repository: https://github.com/DevExpress/testcafe-example-multiuser-scenario.

The changes were made in the PR: https://github.com/DevExpress/testcafe-example-multiuser-scenario/pull/3.

By defining FilterSet the way you have, the distribution over the Filter union only happens inside DistributivePick<...>; then when you intersect that with another type mentioning Filter separately, you've essentially said that each side of the intersection is independent of the other. So it shouldn't be surprising that you end up accepting "cross-correlated" members.

What you want to do instead is represent the operation necessary to calculate FilterSet for each member of the Filter union separately, and then distribute that operation over the Filter union. If you had an individual filter type named F, then that operation looks like Pick & {filters: Pick[]}. Meaning the intersection needs to occur inside the distributive part and not outside of it.

To distribute over Filter with distributive conditional types, we need to take Filter and assign it to a type parameter F, and then check F with a conditional type. (Distributive conditional types only happen when the checked type is a type parameter). So here's one way to do it:

You should try forcing the OS language with:

Currently, we had to change the canHandleEvent to either Boolean or Promise...

Just to be clear, that's a massive semantic change that will ripple through every layer of the code that uses that method. You can't directly use filter with it anymore, for instance, and any synchronous function that uses it is now potentially asynchronous (and fundamentally, "potentially asynchronous" = "asynchronous"). But if it has to happen, it has to happen! :-)

Your original code using canHandleEvent like this:

How do I print either string or integer in C?

Use a different printf() depending on type.

This can be found here in the HyperSpec: 17.2.1 Satisfying a Two-Argument Test. A list of sequence functions, including member, find, and position, is given. These functions take a two-argument :test or :test-not argument.

If neither a :test nor a :test-not argument is supplied, it is as if a :test argument of #'eql was supplied.

The loop executes a lot faster than the Cypress commands or the zoom operation, you can see it if you add a console.log() just inside the loop
