What is mutation testing? How can we generate test cases “for free”? How to make our software tests bulletproof, so we can refactor the code with more confidence?
At Yumasoft, we believe that testing is an inseparable part of software development. Mutation testing, which recently got a bit more attention in programming communities, is a great way of improving our tests. In today’s article, we’re exploring what mutation testing is and why everyone should be using it 🙂
If you work with a .NET backend that uses JSON.NET for serialization, you might encounter such weird things in the JSON result returned from a controller:
But what you actually want is the real object present there:
After reading this article, you will know how to achieve that 🙂
Based on my personal experience as a remote worker, I’d like to share with you my top 5 places for digital nomads in Southeast Asia. I found all these places having a great vibe for digital nomads.
At Yumasoft, we leverage remote work. It allows people who cooperate with us to freely travel if they’d like to. Everyone can choose to live in a place they feel comfortable. Especially in current times, when pandemic has changed a lot in terms of remote work. Let’s make a good use of it 🙂
Do you even care about naming tests? Or maybe you use some random, not-much-telling names for your test methods? At Yumasoft, we treat testing as an inseparable part of software development. It turns out that the tests you write can tell a lot about your software. However, when named carelessly, these tests have much less value. Let’s talk about naming tests properly, so both programmers and business can get more value of them.
Continuing the topic of frontend tests with
jest, we’re taking a look at StrykerJS today. Stryker Mutator is one of the most popular tools for mutation testing. We recently struggled with configuring StykerJS to work properly with
jest and TypeScript. I’d like to share our solution to these problems in this article.
If you are using
and you’re looking for how to show their results in TeamCity as follows:
Then this article will help you configure that 🙂
Disclaimer: I’m not describing the migration process step-by-step or TypeScript itself in this article. You can find many resources on that online, including official TS docs.
18 months since the beginning of the global pandemic, remote work has changed significantly. Many companies switched from in-office to fully-remote work. Let’s see what are the 10 things this pandemic changed in remote work.
In one of our projects at Yumasoft we needed to replace npm library’s implementation with a custom one. This was needed because one of the components we use created their own version (fork) of this npm package (the component uses this library internally). In order to make the component working correctly, we had to use the component’s authors version of the library, instead of using the original npm package. It turned out to not be an easy task, but finally we found a nice and easy solution.
