This post explains how to integrate the tremendous test runner Vitest with the continuous integration platform Azure Pipelines. If you read the post on integrating with Jest, you'll recognise a lot of common ground with this. Once again we want:
This post explains how to integrate the tremendous test runner Jest with the continuous integration platform Azure Pipelines. Perhaps we're setting up a new project and we've created a new React app with Create React App. This ships with Jest support out of the box. How do we get that plugged into Pipelines such that:
Related: there is a post on Vitest and Azure Pipelines.
I blogged a little while ago around to support integration tests using Autofac. This was specific to Autofac but documented a workaround for a long standing issue with ConfigureTestContainer that was introduced into .NET core 3.0 which affects all third-party containers that use ConfigureTestContainer in their tests.
Updated 2nd Oct 2020: for an approach that works with Autofac 6 and ConfigureTestContainer see this post.
If you're a user of Jest, you've no doubt heard of and perhaps made use of snapshot testing.
Cypress is a fantastic way to write UI tests for your web apps. Just world class. Wait, no. Galaxy class. I'm going to go one further: universe class. You get my drift.
Like pretty much everyone else I've been using PhantomJS to run my JavaScript (or compiled-to-JS) unit tests. It's been great. So when I heard the news that PhantomJS was dead I was genuinely sad. However, the King is dead.... Long live the King! For there is a new hope; it's called Chrome Headless . It's not a separate version of Chrome; rather the ability to run Chrome without a UI is now baked into Google's favourite browser as of v59. (For those history buffs I might as well be clear: the main reason PhantomJS died is because Chrome Headless was in the works.)
I'd like you to close your eyes and imagine a scenario. You're handed a prototype system. You're told it works. It has no documentation. It has 0 unit tests. The hope is that you can take it on, refactor it, make it better and (crucially) not break it. Oh, and you don't really understand what the code does or why it does it either; information on that front is, alas, sorely lacking.
I’ve a love / hate relationship with Coded UI. Well hate / hate might be more accurate. Hate perhaps married with a very grudging respect still underpinned by a wary bitterness. Yes, that’s about the size of it. Why? Well, when Coded UI works, it’s fab. But it’s flaky as anything. Anybody who’s used the technology is presently nodding sagely and holding back the tears. It’s all a bit... tough.
I wrote a while ago about how I was using some different tools in a current project:
Enough with the horrific misquotes - this is about Moq and async (that's my slight justification for robbing Herman Melville).
I previously attempted to migrate my Jasmine tests from JavaScript to TypeScript. The last time I tried it didn't go so well and I bailed. Thank the Lord for source control. But feeling I shouldn't be deterred I decided to have another crack at it.
Anyone who reads my blog will know that I have been long in the habit of writing unit tests for my C# code. I'm cool like that. However, it took me a while to get up and running writing unit tests for my JavaScript code. I finally got there using a combination of Jasmine 2.0 and Chutzpah. (Jasmine being my test framework and Chutzpah being my test runner.)
It started with nuns. Don't all good stories start that way? One of my (many) aunts is a Poor Clare nun. At some point in the distant past I was cajoled into putting together a simple website for her convent. This post is a walkthrough of how to migrate from AngularJS using JavaScript to AngularJS using TypeScript. It just so happens that the AngularJS app in question is the one that belongs to my mother's sister's convent.
Do you like to separate out your unit tests from the project you are testing? I imagine so. My own practice when creating a new project in Visual Studio is to create a separate unit test project alongside whose responsibility is to house unit tests for that new project.
