🐕 Automated Test Vs Unit Test
In a system I've just delivered, I insisted on doing automated unit-testing in spite of the claims that I'd spend way more time doing the tests than I would by testing the system manually. With all my unit tests done, I run more than 400 test cases in less than 10 minutes, and every time I had to do a small change in the code, all it took me to
We use unit tests to find bugs or errors on a single unit or code. We use them to verify the logical integrity of a method or a class. They are easy to implement and very fast to execute. They require significantly fewer resources. Testers use integration tests to validate the integration of several components of code.
Manual vs. Automated testing It's important to make the distinction between manual and automated tests. Manual testing is done in person, by clicking through the application or interacting with the software and APIs with the appropriate tooling.
While unit testing involves testing individual modules of an application, isolated integration testing checks if different modules are working together as a group. Finally, functional testing checks whether the system operates the way it is supposed to. Together, these constitute an application that is bug-free and smooth for the end-user.
Of course, a failing unit test not always means trouble (maybe you need to update the test), but it definitely means that something has changed where you didn't expect it. Repeatedly running a potentially large set of unit tests is much cheaper than doing the testing manually each time. The time you need to debug stuff costs your boss $$$ as well.
1. This is an article about automated tests in Unity and several examples of how we use them while developing our game Sine. It should not serve as a complete tutorial on Unity Test but more like
To create a unit test project. On the File menu, select New > Project, or press Ctrl + Shift + N. On the Create a new project page, type unit test into the search box. Select the project template for the test framework that you want to use, for example MSTest Test Project or NUnit Test Project, and then select Next.
A common problem that can lead to non-testable code in certain languages such as C# is not using dependency injection. Consider using dependency injection so that a mock can easily be injected into your Subject Under Test (SUT) during a unit test. More information on using dependency injection can be found here.
