To add code coverage to a React project created without Create React App (CRA), you need to instrument the source code by running it through the Babel plugin “istanbul”. Here are the steps:
npm install istanbul babel-core babel-loader --save-dev
webpack.config.jsorwebpack.config.babel.js, for processing files through the istanbul plugin:module: {
rules: [
{
test: /\.(js|jsx|ts|tsx)$/,
use: {
loader: 'babel-loader',
options: {
plugins: ['istanbul'],
},
},
exclude: /node_modules/,
},
// ...
],
}
start-server-and-testpackage to your project:npm install start-server-and-test --save-dev
cypress.config.ts, add the following code to include the@cypress/code-coverage/task:import { defineConfig } from "cypress/types/index";export default defineConfig({
e2e: {
setupNodeEvents(on, config) {
require("@cypress/code-coverage/task")(on, config);
return config;
},
video: false,
baseUrl: "http://localhost:3000/",
},
});
e2e.ts, include the following code to use the@cypress/code-coverage/support:import "@cypress/code-coverage/support";
package.json:"test:e2e:run": "start-server-and-test start http://localhost:9000 cy:run",
npm run test:e2e:run
After these steps, you should be able to see the code coverage information in the cypress test runner.

You could try using the NetworkBoundResource architecture pattern. The idea is to have a repository layer that combines both the local database (using Room) and the network data. The repository layer returns a resource object that represents the state of the data being loaded, such as loading, success, and error.
You can define a NetworkBoundResource as follows:
class NetworkBoundResource<ResultType, RequestType> @MainThread constructor(private val appExecutors: AppExecutors) { private val result = MediatorLiveData<Resource<ResultType>>() init { result.value = Resource.loading(null) val dbSource = loadFromDb() result.addSource(dbSource) { data -> result.removeSource(dbSource) if (shouldFetch(data)) { fetchFromNetwork(dbSource) } else { result.addSource(dbSource) { newData -> setValue(Resource.success(newData)) } } } } @MainThread private fun setValue(newValue: Resource<ResultType>) { if (result.value != newValue) { result.value = newValue } } private fun fetchFromNetwork(dbSource: LiveData<ResultType>) { val apiResponse = createCall() result.addSource(dbSource) { newData -> setValue(Resource.loading(newData)) } result.addSource(apiResponse) { response -> result.removeSource(apiResponse) result.removeSource(dbSource) when (response) { is ApiSuccessResponse -> { appExecutors.diskIO().execute { saveCallResult(processResponse(response)) appExecutors.mainThread().execute { result.addSource(loadFromDb()) { newData -> setValue(Resource.success(newData)) } } } } is ApiEmptyResponse -> { appExecutors.mainThread().execute { result.addSource(loadFromDb()) { newData -> setValue(Resource.success(newData)) } } } is ApiErrorResponse -> { onFetchFailed() result.addSource(dbSource) { newData -> setValue(Resource.error(response.errorMessage, newData)) } } } } } protected open fun onFetchFailed() {} fun asLiveData() = result as LiveData<Resource<ResultType>> @WorkerThread protected open fun processResponse(response: ApiSuccessResponse<RequestType>) = response.body @WorkerThread protected abstract fun saveCallResult(item: RequestType) @MainThread protected abstract fun shouldFetch(data: ResultType?): Boolean @MainThread protected abstract fun loadFromDb(): LiveData<ResultType> @MainThread protected abstract fun createCall(): LiveData<ApiResponse<RequestType>> }

The decision to reassign focus when a window is closed is typically based on the window’s behavior when being closed. This behavior is typically controlled by the application that created the window and the specific action that was taken to close the window (e.g. clicking the close button, using a keyboard shortcut, etc.).
For example, some applications may choose to hide the window when it is closed instead of destroying it, which would not trigger the OS to reassign focus. On the other hand, when a WPF window is collapsed, it is treated as if it were closed and the OS will reassign focus as it would with a closed window.
It’s also worth noting that the behavior of window management in Windows can vary depending on the specific version of the operating system and the desktop environment being used.

To access a multiprocessing.Queue from asyncio, you can use the asyncio.Queue. The simplest way to do this is to wrap the multiprocessing.Queue in an asyncio.Queue and use the asyncio.Queue methods to access the data in a safe and reliable manner. You can use asyncio.Queue.put() to insert data into the queue, and asyncio.Queue.get() to retrieve data from the queue.
For synchronization, you can use asyncio.Lock, which provides a simple way to lock access to shared resources. When a task acquires the lock, no other tasks can access the shared resource until the lock is released.
Example implementation:
import asyncio import multiprocessing async def producer(queue, lock): while True: # produce some data data = ... async with lock: await queue.put(data) async def consumer(queue, lock): while True: async with lock: data = await queue.get() # consume the data ... queue = asyncio.Queue() lock = asyncio.Lock() asyncio.run(asyncio.gather(producer(queue, lock), consumer(queue, lock)))This solution is based on asyncio, but the concept can be applied to Trio or Anyio as well.

The error message “JSONError: Unexpected token ‘<‘ at 1:1<html>^” indicates that the response received from the API was in HTML format, instead of JSON format, which is the expected format for most API requests. This error occurs because the client (Postman, in this case) was expecting a JSON response but received an HTML response instead. This could mean that the API endpoint has returned an error page with HTML content, instead of a proper JSON response. To resolve this issue, you should check the API documentation and make sure that the endpoint you are calling returns the correct format. If the issue persists, you should reach out to the API support team for further assistance
