test-environment | Set of tools for the generation of test | Continuous Deployment library

in an Software-in-the-loop test-environment project I use VisualStudio2019 to compile embedded software (C++14, with etl (embedded template library)) for the VisualStudio Unittests (C#). Hence, the embedded software is (stubbed/mocked) at the HAL and OS-Layers and compiled with CLR support (/clr). Now i am stuck at a location where I am slowly getting mad :-(

In the embedded software a state machine is implemented by specific classes. One class has a member of type etl::stack, which implements a stack of fixed size. The fixed-sized stack is implemented in the etl as an aligned storage.

Now comes the VisualStudio compiler, complaining about:

C2711 Function cannot be compiled as managed, consider using #pragma unmanaged. Aligned data types not supported in managed code.

C3820 dataExchangeContainer: Initializers must be managed

I have 'cut' out the related code to a new project to get into details for this issue, to understand what i can do to get this compiled. Below is the example code. You need to get the embeded template library downloaded and put into your project to get this code stumbling over the compiler errors.

I have a simple NextJS project set up, and am having problems getting Jest to recognize my environment variables. I've followed the instructions on https://nextjs.org/docs/basic-features/environment-variables#test-environment-variables to the best of my abilities, but can't get it to work.

Here is a simplfied version of my problem.

(This question is also asked at Github here)

After an upgrade of R to 4.0.2 tests fail because it seems, the algorithm of sort in testthat changed. The following shows, that base::sort() and browser() are fine in R 4.0.2 (See this question, why this check is added.):

Added some time later: we now choose to option 2 from here instead of changing the test. Looking back, cross-platform reproducibility is more important ;-)

As described here, the sort logics changed. My question is, how I could make the following test pass on a LC_COLLATE=German_Switzerland.1252?

Reproducible example: create a package, call it testsort, add test-environment using usethis::use_testthat() and add a file "test-sort.R" in /testsort/tests/testthat/

[Similar questions have been asked and answered before, but the available answers rely on SELENIUM_PROMISE_MANAGER for synchronisation.]

I'm running a test-environment that handles all asynchronous activity with async/await. The AUT loads something in the dom like

I have two projects specified in the jest section of my package.json.

I am getting stuck with database Promises I am using inside the Jest testing framework. Things are running in the wrong order, and following some of my latest changes, Jest is not finishing correctly because an unknown asynchronous operation is not being handled. I am fairly new to Node/Jest.

Here is what I am trying to do. I am setting up Jest inside a multiple Docker container environment to call internal APIs in order to test their JSON outputs, and to run service functions in order to see what change they make against a test-environment MySQL database. To do that, I am:

• using the setupFilesAfterEnv Jest configuration option to point to a setup file, which I believe should be run first
• using the setup file to destroy the test database (if it exists), to recreate it, and then to create some tables
• using mysql2/promise to carry out operations on the database
• using a beforeEach(() => {}) in a test to truncate all tables, in readiness for inserting per-test data, so that tests are not dependent on each other

I can confirm that the setup file for Jest is being run before the first (and only) test file, but what is odd is that a Promise catch() in the test file appears to be thrown before a finally in the setup file.

I will put my code down first, and then speculate on what I vaguely suspect to be a problem.

Here is the setup file, nice and straightforward:

I am following link: https://kubernetes.dask.org/en/latest/, to run dask array on Kubernetes cluster. While running the example code, the worker pod is showing error status as below:

Steps:

1. Installed Kubernetes on 3 nodes(1 Master and 2 workers).

2. pip install dask-kubernetes

3. dask_example.py with code to run dask array (same as example given on link)

4. Worker-spec.yml file with pod configuration (same as example given on link)
