            Running several tests with single initialization/destruction of objects to test
            Asked 2022-Jan-27 at 09:11

            TL;DR: is it possible with pytest to create an instance of an object and then run a battery of tests on the same instance ?

            I have a custom C API, that uses posix threads and does operations on serial ports. My API is an implementation of a custom/proprietary protocol with a master/slave messaging. With simple test programs in C (or in Python), it works correctly.

            But, with pytest, when testing sending and reception of messages, pytest repeatdly open/close the COM port and create/delete the background thread, as each unit test is written in the following manner:

            From what I can see, in your SongManager you are creating Dictionary ret, but not adding any values to. Instead, you are trying to directly assign values: ret[timings] = notes_enc[name];. Dictionary is not an array, you should use Add() method, like this: ret.Add(timings, notes_enc[name]);

            The matched pattern of $str1 is 20/12/2021 13:58:3 AM

            Problems:

            • There's no 20th month

            • There's no 13 AM

            • Can give the wrong answer near a switch from Daylight-Saving Time.

            Also, there's a couple of problems strptime ignores:

            • You should be using %I instead of %H for 12-hour time.

            • There's a lack of leading zeros where they are normally expected (minutes and seconds).

            You appear to be asking the following:

            Given the year, month, day, hour, minute and second components of a local time, how do I obtain the corresponding epoch time so I can perform a difference?

            To achieve this, use Time::Local's timelocal*.

            Note First of all, take a look into your soup /doc_nextpage - There is the truth you processing the data on.

            What happens?

            In your doc_nextpage the html for your sponsored products is empty and thats why you get these None.

            They are empty because they will be provided dynamically by website and requests could not handle this. It is no browser, that will interpret / manipulate data.

            How to fix?

            One option is to simulate browser behavior with selenium and get page_source to process it with beautifulsoup or with selenium itself.

            Data source is UCI public accelerometer data available at this URL https://archive.ics.uci.edu/ml/datasets/Heterogeneity+Activity+Recognition. Possible values for frequency include patterns such as 1 minute, 4 hours, 2 days or simply sec, min, day. For the accepted functions to aggregate data, options are 'floor', 'ceil', 'min', 'max', 'mean'. Custom functions will be available in a future release. Note: You can upsample any missing values by using an option in the resample interface (fill = True). The purpose of the skew optimized as of join is to bucket each set of partition_cols to get the latest source record merged onto the fact table. ts_col = timestamp column for sorting partition_cols = partition columns for defining granular time series for windowing and sorting tsPartitionVal = value to break up each partition into time brackets fraction = overlap fraction right_prefix = prefix used for source columns when merged into fact table. The approximate exponential moving average uses an approximation of the form EMA = e * lag(col,0) + e * (1 - e) * lag(col, 1) + e * (1 - e)^2 * lag(col, 2) to define a rolling moving average based on exponential decay. window = number of lagged values to compute for moving average. Method for computing rolling statistics based on the distinguished timestamp column. rangeBackWindowSecs = number of seconds to look back. Method for transforming the time series to frequency domain based on the distinguished data column. timestep = timestep value to be used for getting the frequency scale. valueCol = name of the time domain data column which will be transformed.
