XUnit–Cancel a test when it takes too long

As part of one of my projects I have a set of smoke tests that I use to test the availability and correct behaviour of an external API.

All our code that interacts with other services is using retries with exponential backoff(through Polly) which helps with the reliability and resiliency of our system.

Unfortunately this also means that when we use the same code for our smoke tests, it takes a lot of time before the tests fail when the external API is not available. Taking into account all the retries, an individual test will fail after about 2 minutes. If you know that we have a lot of smoke tests available, the tests take a long time to execute.

I could reconfigure the retry policies to fail sooner but another option is to cancel a test when it takes too long.

In XUnit you can do this through the Timeout property on the [Fact] attribute.

Remark: Timeout is only supported when parallellization is disabled.

An example

I first disabled the parallel test execution inside the test assembly using:

Then I created a test where I set the timeout to 5000 milliseconds:

After 5 seconds the test is cancelled. Notice that Visual Studio didn’t report the test duration correctly:

I’m really bad at remembering emoji’s. So here is cheat sheet with all emoji’s that can be used in tools that support the github emoji markdown markup: All credits go to rcaviers who created this list.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t

DevToys–A swiss army knife for developers

As a developer there are a lot of small tasks you need to do as part of your coding, debugging and testing activities. DevToys is an offline windows app that tries to help you with these tasks. Instead of using different websites you get a fully offline experience offering help for a large list of tasks. Many tools are available. Here is the current list: Converters JSON <> YAML Timestamp Number Base Cron Parser Encoders / Decoders HTML URL Base64 Text & Image GZip JWT Decoder Formatters JSON SQL XML Generators Hash (MD5, SHA1, SHA256, SHA512) UUID 1 and 4 Lorem Ipsum Checksum Text Escape / Unescape Inspector & Case Converter Regex Tester Text Comparer XML Validator Markdown Preview Graphic Color B
