Ruby is an object-oriented, high-level, general-purpose programming language that is mostly used for developing web applications. In most cases, it is almost similar to Python, which makes it ideal for data analysis, prototyping, etc. It is merely used in most web applications because it offers a faster development code as compared to other languages. There are multiple unit testing frameworks available for Ruby that can be used with the Selenium Grid, but the most popular framework is – Test: Unit.
Test: Unit is based on xUnit principles, and it is available with the standard library of Ruby. It was designed by Kent Beck for the unit testing of web applications. Using this framework, you can easily create unit tests, check results, and to automate unit testing in Ruby.
Test: Unit 1.2.3 is the same version, which is bundled in Ruby 1.8. Thus, it doesn’t require additional downloading of packages. You can install it directly from the library. However, to use the framework, you need prior knowledge of XUnit frameworks and Ruby programming language.
Test: Unit consists of various features and capabilities, but there are a few features that make it different than other frameworks, such as it provides three basic functionalities, which include:
- Ideal tools for executing single tests or a whole group of tests
- A simplified way to define basic pass/fail tests
- Allow gathering related tests together and run them in a group
- Features like GUI test runner, GTK, Fox, make it ideal for splitting some packages
The only drawback of Test: Unit is that it is only suitable for unit testing of Ruby-based applications, and offers compatibility with xUnit frameworks, which means you cannot use it for other testing scenarios.
