    Project mention: Mobile e2e tests using WebdriverIO and Appium | dev.to | 2021-02-28

    These tests are responsible for validating that a single unit is working properly. You can think of a unit as a class or function. These tests are written in an isolated fashion. I mean, if the rest of the system is full of bugs and nothing else work, if this unit work, the test will pass. They are also repeatable. They don't depend on anything else, really. Anytime you run the test, if the code hasn't changed, the test will report the same result. These tests are intimately related to the code quality of your project. If your code is clean, these tests should be relatively easy to write. When writing unit tests in iOS, you usually use XCTest or Quick

    An algorithm to optimize database queries that run multiple times

    Project mention: Show HN: EventReduce – Algorithm to optimise db queries that run multiple times | news.ycombinator.com | 2021-04-21
  • GitHub repo ut

    UT: C++20 μ(micro)/Unit Testing Framework

    Project mention: Another C++ unit testing framework without macros | reddit.com/r/cpp | 2021-04-16

    In Boost.UT there is a number of different styles to add a parametrized test case. All of them are pretty cryptic bue to heavy isage of oeverloaded operators of custom "non-public" classes. Except for the for-loop method, in all other methods the list of parameter values goes after the test procedure definition. I find this inconvenient, as I want to see list of parameter value next to the test name. This is what I used to from the times I was coding a lot of unit tests in C#.
