Jest VS AWS X-Ray

You have selected a testing framework. In my case, it's Jest with Supertest. - Source: dev.to / about 1 month ago

The test frameworks section provides an in-depth look at MochaJS, Jest, Jasmine, Puppeteer, Selenium, and Playwright. We review each framework's ease of use, community support, and overall robustness, supplemented with example unit tests. - Source: dev.to / 2 months ago

Console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. When your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules"... - Source: dev.to / 2 months ago

Note: I will be using Jest as testing framework throughout the examples. - Source: dev.to / 5 months ago

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go! - Source: dev.to / 4 months ago

I also send some annotations and subsegments to X-Ray that makes it easy to identify bottlenecks and Lambda cold starts. - Source: dev.to / 5 months ago

In my eventual use case, this is minor since it'll be run asynchronously, and can take as long as it generally pleases. But that's not as great for our synchronous demo API. So it's time to enable AWS X-Ray to run the distributed tracing over the whole thing. - Source: dev.to / 10 months ago

I've not used AWS' offering but I believe that this is what you can use https://aws.amazon.com/xray/. Source: 12 months ago

AWS X-Ray is the first tracing-specific platform on this list. X-Ray focuses on troubleshooting and debugging use cases enabled by distributed tracing, such as identifying latency bottlenecks or diagnosing the root cause of unusual behavior, particularly in microservices/serverless architectures. - Source: dev.to / about 1 year ago

AWS X-Ray is a distributed tracing system included in the AWS cloud platform, that enables developers to monitor, analyze, and debug distributed applications running on AWS infrastructure. It provides information on how an application is performing and allows developers to identify and resolve performance issues quickly. X-Ray traces requests as they travel through an application, providing a comprehensive view of... - Source: dev.to / about 1 year ago
