You need to define to which object mocks should be injected via @InjectMocks annotation, but it does not work together with @Spy annotation. See mockito issue.
There is the simplest solution to use Mockito.spy instead of @Spy together with @InjectMocks:

I’m using Mockito for unit testing and I want to skip the execution of a method.

I referred to this ticket Skip execution of a line using Mockito. Here, I assume doSomeTask() and createLink() methods are in different classes. But in my case, both the methods are in the same class (ActualClass.java).

Azure Data Explorer (Kusto/KQL) Financial Asset Backtesting Trail Stop

Asked 2022-Mar-16 at 20:24

I have a data set of financial asset prices over time and I'd like to mimic a trail stop for back testing strategies against this data set.

Trail stops are a type of trade order supported by some online brokers that are used as a stop loss or profit protection when opening a position, a trail stop is placed to automatically stop loss when a price condition is met.

The trail stop order will follow an asset price as it increases, and stay at the max during the time the position is open, once the asset price falls below the trail stop max, the position will be closed by the broker.

In this case the trail stop is a percentage of asset price. i.e. asset price less 3%.

I've tried a number of approaches, including summarization and the scan operator, and can't seem to land on a working prototype.

Below is an example data table of an asset with price changes over time.

Answered 2022-Mar-16 at 20:24

Investopedia for a good explanation about trailing stop

Order by position & timestamp
Use prev() to identify the starting of a new position.
Use scan() to calculate running max of CallPremium (always goes up, resets for a new position).
Compare each CallPremium to the running max and check if trailing stop achieved.

QUESTION

What to do with many almost-same if-statements?

Asked 2022-Mar-11 at 05:29

I need help. Im new on coding, so I've developed a game with pygame. It's a game where you fight as a robot against a zombie. If a fireball collides with the zombie, the heart picture will be updated from filled to half and so on.

The Tech-Lead said that this code is not efficient because of the many if statements in the def hearts() method in the Enemy class.

Could you please help me to shorten it? I have absolutely 0 idea what I could do. Thinking about loops, but dont know how to do it. Please help me

Here is my code:

...

ANSWER

Answered 2022-Mar-11 at 00:50

The tech-lead is wrong: your code is perfectly efficient the way it is written. Making the code shorter does not make it faster or more "elegant".

However, shorter code can be easier to maintain and change. Your code is fine as long as the number of heart containers is always exactly 12. But if you want to change that (to increase/decrease the difficultly of the game, or let the player get new heart containers) then this code won't work. It is hard-coded to work with exactly 12 heart containers only.

To change this, put this repetitive code in a loop. You'll need to look at the pattern of how the numbers change and create a small math formula for it. I've come up with the following. (I've also added constants instead of the integer literals, so that the code is easier to read and change.)

QUESTION

invert many small, different-sized matrices python

Asked 2022-Feb-21 at 23:09

I have a block-diagonal sparse matrix in python with hundreds of thousands to millions of rows, but with many different sized blocks between 1x1 and 6x6; for example plt.spy() on a submatrix:

I need the inverse of this matrix without looping in python (too slow). I should be able to extract the block diagonal to get a list of 2d arrays (have not actually implemented this yet), but even then I cannot figure out how to apply, e.g., np.linalg.inv() to a bunch of different size matrices. Any ideas on inverting in sparse matrix form or via a list of diagonal blocks??

...

ANSWER

Answered 2022-Feb-21 at 23:09

AFAIK, there is no way to do that efficiently using Numpy. The best solution would be to group the blocks by size to compute them in a vectorized way (most Numpy function cannot work on array of different sizes). But this solution is not great because Numpy is not designed to compute small arrays and the overhead will be pretty big for such a small blocks.

A solution is to use Numba so to generate a fast native code to compute your blocks efficiently. Numba supports typed lists and np.linalg.inv. If your input is a sparse matrix the best solution would be to extract the sub-blocks directly from it. However, Numba does not supports the Scipy's sparse matrices yet. That being said, you can for example extract the data and indices fields (which are Numpy array) of a CSR matrix so to compute them using Numba although this is a bit more complex to do.

How to capture windows message from the up/down button of a CDateTimeCtrl control?

Asked 2022-Feb-21 at 08:57

I am using a CDateTimeCtrl, along with a callback field, in my dialog application. All works well as intended but I want to capture the windows message when the up-down button ( looks a lot like the spin control) of the CDateTimeCtrl is clicked without success. Spy++ reported the class of the up-down button to be msctls_updown32. Spy++ message log offer no clue either. How do I capture the mouse click messages from this up-down control ( looks like an OLE control to me)?

Not too sure about your use of the key Target Allocation , but if your plan is to adjust the maximum holding weight till you have a 100% portfolio allocation, you can use the following code to run a loop on each column.

Must note that this will not work if your max weight has a decimal precision of > 2 decimals.
